Can Heat Make You Nauseous?

Excess exposure to heat can make some people feel ill. Illness caused by heat can happen to anybody. The average body temperature is 37°C (98.6F), although body temperature can range between 36.1°C to 37.2°C, it is still considered as normal. Depending on how agile you are, or the time of the day, your body temperature can vary. Young people tend to have a higher body temperature than old people. 

Too much heat can cause heat exhaustion. Heat exhaustion is a term used to describe the feeling of illness after too much exposure to heat. Dehydration usually follows after heat exhaustion. Dehydration is the state in which the water level in the body drops below normal. Dehydration causes serious thirst. 

Heat exhaustion exists in two ways which are: (1) Water depletion (2) Salt depletion. 

1. Water depletion is the state in which the water level in the body goes below normal. There is not enough water in the body, and as a result, leads to serious thirst, headache, weakness and loss of consciousness.

3. Health conditions: There are several health-related conditions in which people suffering from these kinds of illnesses are more prone to heat exhaustion. People suffering from diseases like diabetes, HBP, obesity, liver and kidney disease, heart disease, alcoholism etc. are more prone to hospitalisation and death from heat-related illnesses.
