Diabetes, poorly controlled, may contribute to dehydration and may be aggravated by excessive heat. Diarrhea may contribute to dehydration. Obesity requires increased energy to move around and the extra insulation reduces heat loss - both contributing to the body's overall heat gain. Acclimatization So far in this guideline, we have shown the consequences of lack of acclimatization. This section will show methods to achieve acclimatization and prevent these consequences.
Acclimatization is the process by which the body becomes accustomed to heat.
During first exposures to a hot environment, workers often feel very tired, irritable and 'too hot'. Body temperatures often rise. After repeated exposures these symptoms decrease or disappear. When this occurs a person is considered to be acclimatized. This period of 'repeated exposure' is not the same for everyone.
