Usually, when our body temperatures get high due to heat, we sweat. Sweating is the natural mechanism of the body in order to remove excess heat and sometimes urea from the body.

Droplets of water mixed salt and urea are excreted through the small pores of the skin. Usually, these pores are there all over the body. Sweating can lead to bad odors depending on where it is coming from.

Coming back to heat rash, it occurs when these pores through which sweat comes out are blocked. The clogged pores prevent sweat from evaporating. Additionally, friction and these blocked pores of the skin results in the formation of small red bumps. These bumps are often prickly and itchy [1, 2].

We call this bumps as “heat rash“. These bumps are often cause a lot of problems.

As problematic they are, these painful blisters may be found found on the parts of the body that rub together. These type of body parts include the inner thighs, under the arms, necks, armpits, and the elbows [2].

Also, those who are living in hot and humid locations and conditions are prone to getting heat rash. Even so, people who are overweight and obese also can suffer from heat rash [2].
