Age
A person’s age is a risk factor for causing heat intolerance. In general, older adults are more likely than younger people to experience heat-related health problems such as heat exhaustion and heat stroke. This is because older adults often have reduced physical fitness levels, making it harder to cool down quickly when temperatures rise.
Their bodies also produce less sweat than younger people in hot weather conditions. In addition, many older people take medications that make them more sensitive to the effects of heat exposure. One study shows that people older than 65 are more likely than younger people to experience heat-related illness when they’re exposed to temperatures above 90 degrees in the first three days after they arrive at a summer camp.
