Content: The effects of heat on people’s health in the UK starts at relatively modest temperatures. Epidemiological studies have shown that maximum air temperatures of only 23- 24 ̊C are associated with excess summer mortality. Physiologically, when the ambient temperature is higher than the skin temperature, the body has to regulate its temperature by losing heat through sweating. At this stage if any other factor reduces the body’s effectiveness of sweating – such as dehydration, close fitting clothing or taking certain medications – it can cause the body to overheat. Acclimatisation and adaptation play an important part in how well people can tolerate different levels of heat. This is why people in somewhere like Madrid are more accustomed to higher temperatures than people in London. HIW: What is the highest temperature a human body can tolerate? PS: There are actually no studies that we are aware of that have identified a maximum temperature.
