Cold increases the risk of death
The research experts of the Chinese center for control and prevention of diseases in Podansko University have shown that between cold and mortality there is a connection. According to the opinion of scientists, the cold increases the risk of death mainly due to diseases of the heart, blood vessels and lungs.
Chinese researchers have analyzed almost two million (1826186) cases of natural death, which was recorded in 272 cities in the period from 2013 to 2015. In particular, it was death caused by the effects of cardiovascular and respiratory diseases, coronary heart disease, strokes and chronic obstructive pulmonary disease (COPD).
Having studied the circumstances of the death people, experts came to the conclusion that the increase in risk is due to two weather factors – a strong cold and heat. Of the total number of deaths 14,33% took place in conditions adverse to the health of the temperature regimes. Thus, according to the researchers, the impact of cold on human health is more destructive in comparison with the hot weather.
“When were in negative values of air temperature started, the risk of death rapidly decreased. The probability of getting sick from hypothermia in humans has persisted for two weeks, whereas from the heat – no more than two or three days,” – said the authors of the project.
The researchers emphasize that a cold is a serious factor increasing the risk of cardiovascular disease. According to them, the heart of cold weather is having a greater negative impact than respiratory disease: of 17.48% against of 10.57%. Particularly sensitive to cold children, women and people older than 75 years.
The calculations of experts testify that the most comfortable for the human body weather is nice and warm – plus of 22.8 degrees Celsius. When the temperature begins to rise and exceed the threshold, the risk of death increases the more, the more warmed up the air.
