This is Jamie Glick. I'm here to talk about flushed abdominal skin after running. Flushed abdominal skin after running is a normal occurrence that happens as an adaption after you run. But it's important not to be confused with a more serious condition such as heat stroke. When you're running the body likes to keep itself in balance. And this balance is called homeostasis. One of the things the body has to do when you're running is maintain your temperature at an even level. When you're running your body generates a lot of heat. All the muscle working generate heat, the heart pumping blood out, the heart generates heat. The body has to have a way to cool you off. So one of the ways the body does this is by expanding your blood vessels. A larger blood vessel can carry more blood. It also, these expanded blood vessels now sit closer to the body's surface. And when they sit closer to the surface they can let off that heat through the skin. Another thing your body does is sweat. The sweat causes a nice layer of moisture on your body and that moisture can then go off into the air and also let off excess heat. And it's important that your skin flushing is not confused with a heat rash. A heat rash is a potentially very serious condition that can lead to a heat stroke, but the rash would come on first. And the rash is a raised pimply lesion on the skin. It is a lot of times under the arms, under the chest, or around the neck. A heat rash is different because this is more on the abdomen, on the chest and on the neck but it's not raised. So that's the important differentiation between a heat rash and just a plain flushing of the skin which is normal.
