Mortality rate increases with temperature

According to researchers, climate changes will make summer hotter. This phenomenon will lead to higher mortality rates. Mercedes Medina-Ramón, of Harvard Medical School, USA said: "The mortality rate will increase by 1.59% because of sudden cold but if it is abnormally hot, this rate will increase to 5.74%."

Medina-Ramón and his colleagues studied the relationship between temperature and mortality in 50 US cities from 1989 to 2000. They found that heart attack and heart-related diseases were intact. multiplication of many deaths but mortality from these diseases tends to increase with the increase of temperature.

The research team said the use of massively heating systems in the United States helps people resist sudden colds. But many workplaces and many families are still not equipped with so much air conditioning. As a result, they found cities with less air conditioning and a larger population would have a higher death rate on hot summer days.

They also caution that equipping national air conditioning is not a good advice.

Medina-Ramón said: "The regulation itself also causes problems related to climate change. The more we use air conditioning, the more energy we will use and therefore carbon dioxide is emissions will increase, making climate problems worse. "

In the past few days, hot weather in southeastern Europe has killed 38 people. Romania was worst affected with at least 23 deaths. Greece and Italy are also affected by this heat wave.
