The topic of effects of cold on the human body never stops exiting both ordinary people and scientists all over the world. A lot of research were done on this topic, as well as many scientific papers and publications were written.
Researchers found that the colder it is, the slower is the process that leads to death of body cells. In other words, cold has a beneficial effect on life expectancy.
The same process causes many diseases associated with aging. Cells have control mechanisms that remove spent proteins. However, protection weakens with increasing age, and this is one of the main causes of cardiovascular diseases, sclerosis, Alzheimer's and Parkinson's diseases.
