When temperature and the humidity is high at the same time or when the temperature exceeds a certain threshold, human’s ability to cool their bodies through sweating is reduced.
In such instances, the real threat is heat related illnesses to life.
Children, elderly and the obese people have a high risk of developing heat illnesses including outdoor workers. People taking certain medications or consuming alcohol also have high risk. Athletes in superb healthy conditions can also succumb to heat related illnesses if ignoring the early warning signs.
