Heat exhaustion and heat stroke are the two main heat related conditions. While heat stroke is a serious condition which needs prompt medical attention, heat exhaustion is less severe than heat stroke and can be termed as the precursor to heat stroke.
Heat exhaustion happens if the body gets overheated internally but not able to cool off quickly and sufficiently. When the body overheats, for example, during athletics and outdoor sports or physical exercises like workouts, gardening, etc. it raises the body temperature. But if water or other fluids are not taken in timely and the extra heat is not passed out of the body sufficiently either through natural cooling or artificial cooling it leads to heat exhaustion. People who are overweight, are drinking alcohol, or are patient of cardiovascular disease, or are pregnant pose greater risk of heat exhaustion.
There are two types of heat exhaustion:
1. Water depletion - The symptoms are
2. Salt depletion - The symptoms are
Sometimes while working outside in the heat your skin may suddenly become cold and clammy or you may start sweating excessively or you may have headache or feel nauseous. These may be the symptoms of heat exhaustion and you should then stop your work, take rest under a shade, drink some water or fluid mixed with body salts.
If you ignore the symptoms and continue to work in the heat it may eventually lead to serious and emergency condition called heat stroke. Heat stroke, if not treated promptly, can potentially damage brain or other organs or even cost you your life.
