Of all the natural disasters, heat is the number one killer, studies show. And as temperatures continue to rise due to the climate crisis, scientists expect it to make even more people sick.
Heat waves are already occurring more and more often. In the 1960s, Americans saw about two heat waves a year, and by 2010, there were six a year, according to the U.S. Environmental Protection Agency.
Heat-related illnesses are the leading cause of death among athletes according to the US Centers for Disease Control and Prevention. But this can be a problem for anyone who performs activities at peak heat.
The National Weather Service in America has published some tips for coping with the heat this week. Doctors have encouraged people to stay indoors as long as possible. The elderly, children and people with chronic illnesses are most at risk for heat-related illnesses, according to the CDC.
Two of the most common heat-related conditions are heat stroke and fatigue.
If a person is hit by heat, the body can not cool down. Its temperature rises rapidly and the natural cooling mechanism – sweat – fails. A person’s temperature can rise to 106 degrees or above in just 10 or 15 minutes. This can lead to death.
Heat exhaustion occurs when the body loses too much water or salt due to excessive sweating. This can come with symptoms like, dizziness, irritability, thirst, headache and high body temperature.In both conditions, urgent help is needed quickly.
