What Are Sweat Pimples?
When sweat mixes with oil, dirt and bacteria clogging the pores, sometimes small, red and pus-filled bumps appear on the skin, these are known as sweat pimples. These breakouts mostly appear on the face, back, chest, and forehead, mainly after sweating a lot.
Causes of Sweat Pimples
1. Sweat and Oil Build-up – If you sweat a lot, then excess sweat can trap dirt and bacteria in the pores, which then leads to pimples due to body heat.
2. Clogged Pores – Sweat when not washed off properly, mixes with sebum, resulting in breakouts.
3. Friction from Clothing – An environment is created for acne-causing bacteria to thrive when you wear tight clothes, as they trap sweat.
4. Heat and Humidity – If the climate is hot, you tend to sweat more, which can lead to summer pimples on face and body.
What Is Heat Rash?
Heat rash is another name for prickly heat or miliaria, this starts to show up when sweat gets trapped under the skin because of blocked sweat ducts. Small red or clear bumps start to show, which causes itchiness, and a prickling sensation. Compared to sweat pimples, clogged pores don’t cause heat rash but sweat trapped beneath the skin’s surface causes heat rash. Medline Plus
