What Causes Heat Rash?

Overheating

Overheating can cause heat rash because it causes individuals to sweat profusely. There are many potential causes of getting overheated. Some examples are wearing clothes that are too warm for the weather, using heated blankets, and spending too much time in a hot area. Other causes include having a fever or being in a hot tub or a sauna. It is important to dress in cool clothes when going outside on a hot day. Wearing loose clothes is also a good idea because tight clothes can create friction on the skin and increase the risk of getting heat rash. If there is a heat wave or if individuals are in a very hot climate, it is important to spend as much time as possible indoors and stay hydrated. When individuals are using heated blankets, they should not leave them on for too long, as this can cause the skin to overheat and even burn. Individuals should also avoid staying in a hot tub or a sauna for a long time. The best thing anyone can do to avoid heat rash is simply to stay cool and avoid getting overheated.

Intense Physical Exercise

Intense physical exercise is a common cause of heat rash. Individuals tend to sweat a lot when they exercise intensely, especially if they are exercising outdoors when it is hot. Heat rash from exercise can be prevented by wearing loose, comfortable clothing, taking a shower as soon as possible after working out, and taking measures to stay cool while working out. For example, if it is hot outside, individuals may want to consider working out indoors with air conditioning. If they prefer to work out outside, they should try to go in the morning when it is not as hot. Some individuals play sports and do not have the option of working out indoors or choosing the time they exercise. Using a portable fan, pouring cold water over the face, and drinking ice-cold beverages are also ways to stay cool while working out outdoors.
