Usually, when our body temperatures get high due to heat, we sweat. Sweating is the natural mechanism of the body to remove excess heat and sometimes urea from the body.
Droplets of water mixed with salt and urea come out through the tiny pores of the skin. Usually, these pores are there all over the body. Therefore, sweating can lead to foul odors depending on where it comes from.
Coming back to heat rash, it occurs when these pores through which sweat comes out get blocked. The clogged pores prevent work from evaporating. Friction and these blocked pores of the skin results in the formation of small red bumps. These bumps are often spiky and itchy [1, 2].
We call these bumps “heat rash .”These bumps often cause a lot of problems. The other name for heat rash is miliaria .
