Heat rash is an annoying condition that occurs when a person is exposed to extremely warm temperatures. People who work outdoors or reside in humid, warm climates are more prone to getting heat rash. As the skin begins to sweat under clothing, the layers of garment may disrupt this process, causing sweat to become trapped and skin to chafe as it rubs against damp clothes. The result can be prickly, red bumps that rise up on the skin's surface. There are several ways to avoid heat rash, and ways to treat it at home, if you have to contend with this condition.
One of the best ways to avoid a rash is to avoid heat and sweating. Whenever possible, stay indoors during the summer, especially during the hottest part of the day. When it's not possible to stay indoors, dress in light layers. Sweating is the body's natural cooling mechanism, and allowing this process to occur with minimal interruption will help.
If heat rash occurs, thankfully, it will heal on its own given time. There are, however, several things you can do to relieve the discomfort and aid in faster healing in the meantime.
- Cool skin down by showering in cool water, applying ice packs, or sitting in air conditioned spaces.
- Soothe skin by taking a bath with colloidal oatmeal, which has soothing properties.
- Air dry skin rather than towel dry to minimize irritation.
- Apply a powder, such as Gold Bond, talcum, or baking soda to absorb moisture and soothe chafed skin.
- Apply a healing lotion or gel, such as calamine or aloe vera.
Once heat rash has developed, it will usually dissipate quickly, but individuals with more sensitive skin may take longer to see complete relief. During the healing process, follow the above regimen daily and avoid scratching the skin.
