I had a full-blown heat stroke while working In the engine room of a Navy ship in the Persian Gulf, more than 40 years ago. The temperature in the lower level was usually between 95 and 120 F, and we usually spent 18 hours a day down there. We ran aground and went to emergency power, which shut off the ventilation to the lower level. My last memory was of everything looking oddly brown, and then nothing. A shipmate saved my life by carrying me over his shoulder up multiple levels, and dumping me in a 100 gallon vat of iced tea. Two days later they sent me right back down there. Over the years I have learned to watch for the onset of a second bout. If I get really hot, I stop sweating, and start to feel sort of disembodied, so that I either jump into our pond or run the hose over myself. The damage seems to be permanent; don’t let it happen to you.

I remember being in the engine room of HMS Fearless, when taking part in a Nuclear/Biologic contamination prevention drill; which meant shutting nearly all of the ventilation down. We got up to 60 degrees C with very high relative humidity. The control cubicle was air conditioned to a more tolerable level, but for routine rounds of the machinery space itself people were rationed to 10 minutes at a time.

I live in Arizona and it’s currently 114°. Amazingly, there isn’t a lot of detailed information on heat stroke symptoms in the media or displayed in public here. Thank you for the information. I hope I never need to use it, but it’s reassuring to have.

UK and North West Coast North America traditionally do not have any air conditioners. That is why over 600 people died in British Columbia during last years heat dome.

As a military veteran, I would only like to add to what Dr John stated on hydration. If the temps are beyond your personal threshold, keep an eye on your sweating. If you stop sweating, this is not good. Your body is too depleted of water and it can’t sacrifice any more towards sweat. Hydrate in small amounts even if you don’t feel thirsty. Please be sure to add a little salt to your water, or eat a few salty crisps/chips while hydrating. If you add salt to the water, you shouldn’t be able to taste it, just a very small amount to replenish what is lost in sweating. Many cases that end up in ER are not because the person is not drinking, it’s due to lack of salts. If you are drinking lots, but no salt, this can lead to nausea, vomiting, and saline IV at the ER. Love to you all and God bless!

The cold pack in the groin is the most important, that cooled me down faster than anything.

I was in my mid-twentys sunning in my backyard in SoCal. When I sat up I knew I was in serious trouble.”; lightheaded, nauseous, shaky, heart racing. I barely crawled to my shower and with my last bit of strength turned the cold water on and just laid on the floor of the shower. What a blessed difference that made. I realize I could have died. I am so much more careful now. Thank you to my Guardian Angel!

Friendly warning: my hubby spent a long sunny day fishing on a boat. Surrounded by water and only soda pop to drink. After about 6 hours they were all feeling horrible and hubby was showing all the symptoms Doc covered. I had him sit in the lake while they trailered the boat then got him home. Made him sit in his underwear in front of the air conditioner with a glass of ice water. It took weeks for him to get his strength back. So even idle heatstroke can happen. Take care

Good Morning Dr Campbell .. An interesting topic and quite relevant at the moment .. thank you for that. Something to add if I may please? Those who have worked in the South African Mining Industry .. myself, Deep Level Gold Mining (2000m + underground) are fully aware of the hazards of 'Heat Stroke' .. with having had Training in the Identification of 'Conditions Conducive to Heat Sroke'. Put simply .. an environmental 'Wet Bulb' / WB Thermometer Temperature of 27.5°C and above (where Regulatory Formal Precautions .. Codes of Practice, Procedures, Standards, etc, had to be taken in the Management of Heat Stroke .. Prevention / Identification / Treatment) and with an upper limit of 32.5°C WB being the cut-off where the workers had to be withdrawn from the specific workplace until the environmental condidtions therein could be brought back to within standard. 'Ventilation'. Properly ventilating / increasing the flow of fresh air through the affected area was generally the means of cooling it down. Thus .. even environmental temperatures well UNDER 30°C, should the air be saturated / very humid, can constitute a hazard. As a Certified 'Acclimatisation Technician' and having worked with and under the guidance of the South African Chamber of Mines Research Organisation - Industrial Hygiene Division, herewith some additional handy tips for the layman .. everything that you have stated being correct and relevant: * 'Heat Exhaustion' is not 'Heat Stroke' .. the former being more common, normally preceding the latter and easier to recognise and treat. 'Heat Stroke' can only be formally diagnosed by taking Tissue Samples .. unfortunately all too often from the deceased or, very least, brain / organ damaged. * The most accurate means to measure body temperature is rectally .. thus the specialist Mining First Aid Kits (and my current) containing only those. They're much more robust anyway Again, added to that already said .. PREVENTION: Vitamin C / Ascorbic Acid, has been found to assist in natural body acclimatisation to and performance in, heat. 250mg per day. TREATMENT: * Must start IMMEDIATELY and be MAINTAINED for at least TWO Hours until the Body Temperature (ideally rectal) has fallen below 40°C .. or TRAINED Medical Assistance has arrived. Please note, 'TRAINED' means exactly that .. in the SPECIFIC Recognition and Treatment of Heat Stroke. Stopping treatment and just bundling the Victim into an Ambulance followed by a sometimes lengthy trip to Hospital can do more harm than good. * Move the Victim to a SAFE shady / cooler spot. ICE BATHS .. CAREFUL! In unqualified hands they can be counter-productive .. more on that later. * Strip them to the bare minimum .. ideally naked if possible. * Sprinkle the body with water (not drench) while directing a flow of cooling air over it ..fanning with an item of clothing / newspaper / etc, electric fan, compressed air, whatever. This will, as you explained, stimulate evaporation and subsequent cooling of the skin. * Massage the body / skin from the body extremities towards the Heart. This stimulates Capillary Blood Flow .. the now-cooler blood from the skin surface back into the Circulatory System towards the Heart, Organs and most important, Brain. * Monitor the ABC .. namely Breathing and Heart. The victim could be unconscious and CPR may be necessary. * Should the Victim be conscious and aware, give water to drink and reassure. * Beware of 'overcooling'. Reduce / stop cooling should 'goosebumps' appear on the skin. Overcooling can result in blood capillary constriction, reduced blood flow to the skin surface and thus negatively affecting 'venting' of body heat. That is why Ice Baths 'could' possibly be counter-productive in that the skin cooling mechanism may 'shut down' and the internal (stil beingl generated) body heat remains contained deep inside where it will do the most damage. * Maintain Treatment for at AT LEAST two hours until the body temperature has fallen below 40°C and REMAINS consistently so and / or TRAINED Medical Assistance has arrived. * Once the Victim is stable, cover lightly and wait for transport, etc. I hope that this will be of some assistance to those out there. Awareness .. being able to recognise heat-related symptoms and applying correct counter-measures go a long way in the mitigation of this issue. Take care ..

Amazing, you pep right up. (only when you're really sweating) -freeze a gallon jug of water and set it up in front of your fan or put your feet on it -Bowl of ice water and wash cloth and constantly wipe your body down -Night time heat wave- put sheets in the washer and use them while still damp with the fan on you! You'll cool right down and they'll dry quicker than you think... before you know it, it's morning time! Most important thing is to stop doing anything just before the heat of the day kicks in!!!

You've reminded me of a time when my girlfriend and I were traveling around Texas on vacation. One day, we were in San Antonio to visit the Alamo, of course. And while we were down there, we came across a county fair, or some such thing. There were all these young guys milling around, dressed as Confederate soldiers, with muskets, etc. Now, this is mid-afternoon, in blazing heat, and these guys are dressed in thick wool uniforms. I remember talking to one of the young 'soldiers', and asking him how he could stand being dressed like that. He looked so hot and miserable.

As someone who has lived all their life with late temperatures in late 30s and early 40s celcius in summer we can recognise symptoms of heat stroke fairly easily and early. Here are the most common symptoms of heatstroke - headaches, nausea, vomiting, diarrhoea. temperature. Below are the points for protecting yourself from high heat:: 1. Avoid being outside between 10 am and 5 pm - best option. Kids to be especially careful. 2. Fluids - double the fluid intake. No carbonated drinks, no coke no Pepsi no alcohol and no cold beer does not really help if you are exposed to heat. Cool water with lemon juice and sugar several times a day. Note cool not iced water. 3. Dehydration is your biggest enemy in the heat - if you are dehydrated go to the pharmacy and get an electrolyte sachet. Dissolve it in 1litre of cool water and drink up slowly. In my country we get these in tetrapacks. As the doc says in this video - your urine should be light in colour not dark and you should be urinating frequently. 4. Head and ears should be protected while outside. Eyes as well if your eyes are sensitive (that's why in cultures with high heat folks wear complicated head gear and women cover their heads) 5. DO NOT run, jog or exercise in the day time in the sun (i.e. between 10 am and 5 pm) 6. Wet a cotton towel and wipe your face behind the neck, behind your ears regularly if you are outside. Alternatively, spray your face, neck and the top of your head with a spray bottle - again cool not iced water. 7. Wear cotton clothes - best way for your body to breath. Polyester, rayon, nylon all enemies of high heat. 8. Do not suddenly drink or wash yourself with water from the fridge or iced water if you have just come inside from high heat. 9. If you don't have an AC buy a light thin cotton bedsheet in color green or blue wet it, wring it...add eu de Cologne if available and hang it on the curtain rods and open the windows and switch on a fan....this will cool your home as long as there is no direct sunlight. I don't know the science behind this but we've been doing this for centuries. It's really sad that I hv to write this on a thread to folks in the UK. God knows what will happen to us here in my country. We can probably cook in the sun in a couple of years. 😀😀😀

Science behind the wet sheet cooling the room is that when the water in the sheet evaporates it takes heat out of the surrounding air. That's how sweating works. I'll note that a red face is also another sign of heat stroke. I saw that when hiking at Grand Canyon.

She repeatedly encouraged everyone on the tour to make sure that we wore hats, drinks loads of water (she made sure the water on the coach was always chilled and available). And she also insisted that we stood in the shade at every opportunity. I noticed how stressed she was about the heat so I asked her if, as an Italian, she did not like the heat. Her answer shocked the hell out of me. She said she wasn’t stressed because she didn’t like the heat. She was stressed because on one of her previous tours, a gentleman suffered heatstroke and died!

They were from Massachusetts, just hiked here in AZ starting at 8am, got lost, it was 107 and humid at the time at 1pm when i got there. The dead lady was still wearing full boots, socks, dark blue thick exercise pants, shirt with vest and had a huge mop of brown curly hair. I had sandals, light short pants and a big hat. The husband told me to help her in the parking lot, I ran to her. Rest in peace. And if it's too hot, seek shade, relax and just wait. They were pushing for the parking lot after having been lost for hours and finally finding the trail again. The last uphill section did her in, her belly was already swelling. I'll never forget how their 'professional' hiking equipment totally failed them. Heck if you're in that kind of situation, undress and seek shade. Wait until night, seek out water no matter how dirty it is. What a loss, the husband was just destroyed

I forced myself to continue but if I go there again I will carry water to douse myself if necessary. And carry a little battery powered fan too. At my home the summers are getting hotter and I am seriously considering moving further north. Many years ago I worked construction in Florida and the heat was bad. After sweating for a few hours I would get cold water to drink and it seemed that as soon it hit my mouth it evaporated. It was the best tasting water! The flavor of "WET"!!!

I would be happy to be virtually interviewed to go over in more detail the precautions I take that allow me to run in these conditions. I run on days where there are excessive heat warnings and people are warned not to go outside except for short periods of time. I wear tight running clothes because they get wet with sweat and keep me cool. Loose fitting clothes don’t cool much because the wet fabric needs to be in direct skin contact to provide any cooling!

I’ve had this happen years ago. It drastically lowered my tolerance to heat and even changed the way I think and speak. The words are in my thoughts but they don’t come out sometimes. Don’t let this happen to you because there’s no going back.

Great timely information John. I've seen it in Afghan where lads would collapse and become almost delirious and had to be rapidly cooled. Its not something we're used to in the UK but anyone working in EMS/ED please be aware of the early symptoms when you're working in full PPE especially during an arrest or extracting your patients. I experienced a mild case last summer on a working arrest in a bathroom. I'd neglected hydration and became very confused and my head went a bit fuzzy and my legs became very cramped but I ignored it/didn't recognise it and worked through but became really quite unwell and very tachy about 15 minutes after first realising something was wrong and almost collapsed down a flight of stairs. I thought I was just dehydrated and took on some diarolyte but I had to strip off and ended up going home unable to finish my shift, thankfully I was with an Aussie who knew what was going on and he probably saved me from going man down. Should have known better, but the onset felt quite rapid. Look after yourselves and those around you folks you're no good to your patients if you become a casualty yourself. Anyone with young kids or elderly relatives be aware as they can go downhill much quicker as they struggle to regulate their temperature, if you recognise the symptoms get help.

My daughter’s a student paramedic, experienced the same trying to extract a patient from a tiny room upstairs to the ambulance. There was a thermometer in the room and she watched it increase by 4 degC as they worked on the patient. Took 5 of them to get the patient out of a series of narrow stairs and over a wall. She was decidedly unwell afterwards, the other paramedics made her eat and drink and she gradually recovered.

Its winter in Australia at the moment, so I'm sitting at home with the heating on, but we're very familiar with temps well above 40C degrees in summer, so we're pretty aware of the heat, but people still get themselves into trouble with heatstroke every year. Most healthy people who don't do anything silly will be fine, but you can get into strife easily if you don't take some basic precautions like drinking plenty of water.

Such a knowledgeable man. You have taught me so much in all areas of your posts.

All good advice Dr John. A have worked as a Geologist for over 35 years and always in the hottest deserts or hot and humid jungles in more than 80 countries. I've seen people die of heat stroke when it was preventable. I have routinely 'chewed out' the men and women who work for me for not adhering to some simple rules of the bush: 1) Always carry more water than you need and force yourself to drink every 15mins (I drink up to 20 litres during the day on some jobs... about 25% of my body weight, but always over 10 litres a day). Never leave the safety of the camp or vehicle without an excess of water. If your pee is darker than pale straw yellow you are dehydrated. 2) Wear light cotton clothing that is at least two sizes larger than you would normally wear. A low denier cotton will allow a breeze to flow through. No long pants... if you're worried about snakes wear loose gaiters around your lower legs. 3) Wear a wide brimmed hat!!! About 20% of the heat (or cold in an cold climate) is accumulating around your head (or escaping when it's cold). On my jobs if you don't have a hat you don't work. And baseball caps don't count for a hat! 4) If you must be in the open, rest under the shade of a tree or brush as often as possible. Don't discuss a work schedule or hiking plan in the blazing sun! 5) Start the work day at first light (before you can read the print in a newspaper). Take shelter under a tree during the middle of the day and resume your activity after 3pm even if this means working into the evening to last light. Working during the middle of the day has only a work rate of about 30% of the cooler hours anyway. I've worked in areas where the temperature has reached 50 degC during the middle of the day... you are stupid to try to work during those hours. 6) Monitor the demeanor of your colleagues. Heat stroke can come on very quickly so at the slightest hint of a problem demand him/her to take shelter and drink. 7) Take a dose of hydration salts twice during the day (I like the orange flavoured sachets) if working in the heat. You will lose an enormous amount of salt in hot climates and it can be a big problem (not just the cramps). 8) If you're a lily white skinned Englishman/woman you will need a sun block but try to get one that allows the skin to 'breathe'. Your skin doesn't get as much evaporative cooling effect if you slather it on thick. There's much more but I might end on sad note. About 25 years ago a European family of four decided they would travel from their minus 15 degC winter and visit Uluru (Ayers Rock) and the Olgas in Australia during a normal day for those parts of 45 degC. Their flight connections took them all the way to Uluru. Excited to hike around the Olgas area they started their adventure within an hour of checking into the hotel. Withing 3 hours they had all perished. No acclimatization, not enough water, poorly dressed, they had no chance. Heat kills if you're not prepared. It happens often but is always preventable.

Yes 20 litres a day is an exception but when you're lugging a 25-30kg pack over hill and dale in the Tanami, Great Sandy, Kimberly, Kalahari etc and can't work at a leisurely pace you will sweat big time. A litre to 1.5lts per hour is nothing. If I were a tourist in these areas (there are virtually none in the deep desert) I could get away with less than 6 litres a day. Remember it's only the equivalent of a cup of water every 15 minutes. And you will live.

I went to high school in the 70s and they taught everyone playing sports how to recognize heat stroke. I was running cross-country and noticed one of the runners puking on the side of the road, I told him get into a drainage ditch and soak his head. I instructed another runner to go to the nearest house and call our coach. I had him continue to douse his head and used his t-shirt to soak his body. Coach came and picked him up, told me it was a good thing I made him get in the nasty ditch water he was suffering a heat stroke, he never ran cross-country again.

Oh... great information!!! I had it as a teenager long time ago, in Brazil, after a bike ride at the pike of summer, at noon... I know now I was very lucky and remember very well the situation. It is exactly as described above by Dr. Campbell; I remember arriving home and taking my bike into the elevator to get to my apartment on the third floor and the feeling of intense dizziness, loss of vision, hearing noises still but from far away... I realized I was loosing consciousness, slowly reached out to the ground to avoid a fall and I fought it as much as I could to remain awake. In my mind at that moment, I just thought It could not happen in the elevator... By miracle, someone reach out to me in the elevator, I could hear the voice of that person from far but I had no vision, I remember saying, I can't see! I can't see! It was our housekeeper going out for errands that by miracle was there waiting for the elevator and rescued me. She pull me out of the elevator, sat me down on the stairwell nearby, lower my head down for a bit,( my vision and hearing returned) and helped into my home. She handle me Ice... I rest for a bit, took a cold shower and learned my lesson. Never again went to exercise under the sun in hot weather. Just now after this video, I'm shocked to know how serious this condition really is and deeply thanked God for all his blessings.

Excellent Discourse on this very important matter. Having experienced Heatstroke to the point of total collapse, your discussion rings true. Cheers from Michael. Australia.

Running up a hill in Yuma, AZ in mid afternoon in July around 115F, I knew immediately I was in a state of heat exhaustion heading towards heat stroke, all the while my Dad was threatening to take me to the hospital if I vomited one more sip of water while I was in a cool shower. Then my sister made me drink a slightly diluted squeezed lemon juice and though I vomited that up several times, I knew it was working and in a few minutes my digestion calmed down, I was able to hydrate and was eating refried beans 2 hrs later. Don’t know what it was about the lemon juice, but it turned it around for me that day. The cool shower only cooled me down on the outside, but my internal temp was hot. It was scary. Please take heat exhaustion seriously and don’t delay getting medical help.

I’ve learned to carry giant water bottles. During summer I never leave home without a ice chest with water bottles I keep a towel to soak in ice and put it under my arm pit (usually the fastest way to cool your body temp) I work outside doing construction so hydration and body temperature cooler is really a necessity.

John something I haven’t seen covered in British media coverage “ ways to stay cool” is something our grand parents used to do in Australia and New Zealand before A/c was affordable, common practice at the time was to open a window on one side of the house and another on the opposite side. Then you get an ordinary house fan and face it OUT the window. This blows hot air out of the house and sucks cool air in from the open window. Particularly useful at night when houses can stay warmer than the evening outdoor temperature.

Some tips for dealing with high heat temperatures for those who are not used to them. Keep your curtains closed,it stops a huge amount of heat entering your home. Keep windows and doors closed during the day. Drink plenty of room temperature water,cold water feels refreshing but your body doesn’t absorb it as well. Cool loose fitting clothes,the least amount of clothing as possible. Cars become extremely hot when parked,open the doors and windows and wait a few minutes before you get in and don’t leave kids or pets in a parked car,it is not good to sit in a parked car while someone else nips into the shop. Wet a small towel with cold water and keep it round your neck. Stay in the shade. No physical exercise when very hot,wait till it cools down then take a gentle walk. If you have fans and or air conditioning then use it. Keep an eye on the elderly,they don’t feel temperature like we do so make sure they are drinking enough and make sure they are not wearing too many clothes. Fill a hot water bottle with cold water and freeze it,put your feet on it when you go to bed,it will help you feel cooler and get off to sleep easier.

Great stuff John on this as most in the northern climes don't experience these high temps. Down here we see 38+ daily in summer and get somewhat immune to the effects. That does not exclude us from some serious adverse results! An electrical friend was working in a switchroom at our steelworks on a 40+ day and ended up with severe heatstroke.

Eventually, was well enough to get out of bed and explore, but still felt some fatigue for another 2 weeks. I was extremely fit and healthy those days, feeling indestructible - and thought i would be fine. All up, I lost a whole month of a holiday from this error of judgement.

Many years ago, 4 of us were on a bicycling vacation. All guys in our 20's and a mixture of fairly fit to very fit. We had to alter course because of a heat and air pollution wave, which got us all pollution sick in about half an hour. On the new route, we had some hot areas before we could get to a cooler, cleaner, higher altitude. And big climbs. The newly paved road was slanted just right towards the sun to catch a lot of temperature and we had a slight tailwind, which made it hotter, or at least no wind cooling. One of the guys got fairly unsteady and riding poorly. Uphill on a loaded bike at low speed is quite good at revealing balance or mental problems. So we got him in shade and mixed up some lemonade for him, which was the best we had on hand. Makes you really think about what should be in your first aid kit. We got him stable enough to pop over the hill to the next town and lunch at a diner with a big drink. He still wasn't 100%, so he called for a pick up ride. We were quite careful on the downhill into town. A lot of physiological problems incurred during a big hill climb can lead to serious problems on the downhill, leading to crashes. So we watched him closely on the downhill. If you ever have a very challenging time on an uphill, just take a break at the peak before heading back down. You could be unsteady on the downhill, which is not a good thing when you're going 40-50 mph. The other common problem is getting very sweaty on the uphill and then getting hypothermia on the downhill from being wet and suddenly on the shady side of the hill.

Few tips I’ve learned over the years to keep your house cool keep the blinds closed, the sun comes in my back window and the room can become like an oven so now I hang wet towels over the curtain rail I find it really helps. And if I have to go out I run my long headscarf under the cold tap, ring it out pop it in the freezer for 10 mins it helps keep the burning sun of my head and neck, I put my nightdress in a freezer bag in the fridge too, Hope my tips help someone today God bless everyone from London uk

Will be between 100 and 106 for the next seven days in Aurora Missouri in the United States. Worst heat wave in America in my life time I think. Oklahoma will be reaching 115 in some areas. This is crazy and it's happening in Europe also I see.

Here in Seattle we will get to 80 once this coming week, w/lows in 50’s. This is why I moved to/stay put in the great Northwest. My basement bedroom is particularly delightful. And here in my liv rm (no ac of course) I have a down quilt around my legs here at 5p. It’s a bit warm sure, but so cuddly : ). Yes, we get our years w/heatwaves thrown in more frequently now . . . but at least our Summers are arid (left the sauna known as Wash DC behind when I fled Eastcoast at 18 yrs.)

I get my hair wet to cool off in the heat. It makes a big difference.

Your lovly...thanks ! I could listen and take notes from you ALL DAY LONG! What a wonderful Teacher! Thank your wife, for sharing you with all of us.

Bless you for doing this video for us all to cope with possible heat effects Dr John. BTW the Fahrenheit measure is 98.4 So very informative of things could become severe, if folk aren’t aware. My husband had heat stroke in the summer of 1976 and was in a terrible state as a result. However, we managed to get help during the evening and he gradually returned to his normal state, but it was extremely frightening! I hope folk take notice of this video and take great care! Very many thanks indeed

It is actually 98.6 and NOT 98.4. The math formula is (37°C × 9/5) + 32 = 98.6°F

The Summer of 76 was much more Consistent, and before anyone says this one’s going to be hotter. Summer 76 was in the 30s almost every day from end of June through until August 🤦🏻‍♀️ it says a lot when we’re well into Summer and we’ve only had a few days of heat and media channels like this has everyone in a blind panic 😂

@@eveoakley6270 well,you're right that the 'news' tends to be London/southern centric. It is hot here on the south coast,lots of sunbathing going on. Not me,haven't sunbathed since l got badly burnt in my teens during one of those 'long hot summers' of the seventies 🤕 My skin peeled off in chunks for weeks after BUT, we do need your rain desperately,even though we had a fairly wet spring I think the hosepipe ban will start soon,and everything is really drying up What is 'strange' is that it's been dry for weeks,even though it only really 'warmed up' about a week ago Never used to do this,l think 🤔?, the westerly winds of the Atlantic just don't seem as 'wet' as they used to be

After moving to Perth Australia 26 years ago from New Zealand, one thing I've always struggled with is the very hot summers. The summer just past was one of the hottest I can recall, with a solid month of temperatures over 35 degrees and 14 of those over 40 degrees. A couple of days were nudging the 45 degree mark. It's even worse the further north and inland you go. The effect is cumulative too as urban areas retain heat from the previous day and it can be 30 degrees by 9 in the morning. In the mining centres they can have it very tough; an old flatmate of mine working as a diesel fitter worked underground in up to 50 degree temps. One saving grace is Perth has a Mediterranean style climate so doesn't get too humid unlike in the north of the state. Obviously, aircon is a big industry here.

Yes, the consecutive days of heat are a killer, it's almost as if the air con stops working as well as it did in the first few days. AND I live in Melbourne & have never been to WA. I can only imagine the heaviness of the a heat like that, totally exhausting.

I live in the Rhine valley close to the french border. This time of year-if I am out-I try to be out after 5 PM, and carry about half a liter of water with me (canteen half filled) in my ever present Backpack (For Girls: My man-purse). I just went over my backpack to check if I have my mineral tablets with me-nope. I have some petlings (raw-PET bottles that are heated and blown up to the size needed for the bottle) and filled one with some mineral tablets (Neukönigsförder are making them here) and multi vitamin tablets. Put them in the backpack in my medic pocket-there is some first aid kit and an additional thermal blanket in it as well as some glucose tablets ;-) I do not stray to far from civilization or shade, but on some walks some stretches can become uncomfortable, and this city is built in a former swamp close to the Rhine-it can get quite humid here, and then sweating only makes you wet without any cooling effects. I have at least a base-cap or a proper jungle hat with me this time of year (yup, man purse carries it). If it gets up or above 40°C this next days, we should be good-as this is supposed to be very dry air. Drinking and shade should be enough. In case it isn't for me or someone else-I am prepared. And after the Good Dr's talk I know what to do. Maybe I will up my water provision to a liter.

Great info! Don’t forget electrolytes, potassium, and salt. When temps are high, preventative measures are key. I do hot yoga and used to own a heated yoga studio. We recommended electrolytes in 16 oz. of water at least twice a day. If a person seems mentally foggy, slowly dissolving a glucose tablet helps tremendously to activate the blood glucose levels which in turn gets the person’s blood sugar up and helps clear the mental fog quickly. (Note: glucose is to be given to diabetics and/or people who have ANY extreme metabolic issues).

Brilliant, informative and interesting. Thank you Dr Campbell

Timely and appropriate topic, Dr Campbell.

Thank you! Record breaking long summer in Texas, having my hubby watch later tonight. You are so appreciated!!!

It gets over115 degrees here in Las Vegas. Up to 117.

Quite common during summer here in Queensland, Australia

Aircon?

*About thirst* ; as someone who suffers with both anxiety and stress, I've found that when my anxiety and/or stress are high, I don't feel thirst as quickly, if at all, I feel hungry instead, with a particular craving for sweet things (this happens even if my body is showing other signs of dehydration, like deflated and chapped lips). My hypothesis is this an old evolutionary trait where for our primitive ancestors fear and stress typically meant predation, and so the last thing you'd want is to go to the river to drink where predators usually keep watch, so instead, fruit that is rich in water is the safest option. Given the prevalence of both stress and anxiety in our society, I wonder how many people are experiencing the same as me, craving food and sweet things in particular when they are in fact thirsty while stressed/anxious.

As mentioned, these temps are records. The average high this time of year in London is 76F (24C). Tomorrow London with 96F (36C). No A/C in many homes, cafes, shops, on public transportation, etc.

I live near Seattle and born and raised in Ohio, so I really appreciate the 20 degree Celsius (not Centigrade, John) temperature here and how lucky we are for that and adequate water without flooding. Btw, might I suggest putting Celsius first in your notes. I am 72 years old but am quite comfortable with metric as I am sure you are as a medical professional. Thanks for this most informative and timely video! 😃

Never got a heat stroke but had heat exhaustion several times. I would mostly vomit, with dizziness and my vision would darken. I would mostly get it running track in the summers.
