Workout Woes... the Skincare Kind.
I don't know about you, but running - and any sort of exercise for that matter - makes my face red. Sometimes the redness will last for a few minutes, sometimes for a few hours. Thankfully, this isn't something to be concerned about, but it's an interesting example of the many ways that your body and your skin work together.
As you exercise, you build heat. And as you accumulate heat, your internal body temperature will go up - which your body will immediately try to counteract by expanding its vast network of blood vessels. As the warmer blood reaches the vessels closest to the surface of your skin that blood will begin to cool off. So why the red face? Due to the fact that there is such a rich network of blood vessels in your face, the change in color seems more prevalent than in other areas of your body.
Now, ever have itchy skin after exercising? Well, this is more annoying than a bit of unwanted color but it's something you can fix. This itching isn't caused by a particular exercise that you might do, but rather, from the intensity of your exercise. The heat build up that we talked about before, and the maintenance of that internal body temperature, causes inflammation in the skin. The inflammation then triggers the release of histamine, which causes the itching. The best fix is to take a preventative angle: an hour before your workout, take a non-sedative, anti-histamine like allegra, and you should be itch free! Now, if only working out were this easy...
