why does my skin turn red when I run?

Question

I notice it on my legs, specifically at the ankles and above my knees.

Answer 1

Your blood vessels dilate (open up) near to the skin to help loose heat generated by your exercise. A mechanism to export heat and maintain core temperature, thus the skin flushes!!!! Spray water on your skin if you run all the time and the skin will cool ...(and so will you) faster due to evaporative cooling....water draws heat from body and the water then evaporates and leaves the body cooler.

Answer 2

You may not be breathing correctly, or running too hard. When there isn't enough oxygen in your lungs, the heart starts to recycle blood more frequently, which gives you your hue. Try a cooling cream if you go running during lunch. Otherwise, just wash your face with cold water and it should be gone in 10 minutes.

Answer 3

Your body temperature increases and your blood flow increases which causes your skin to turn red. Notice the hotter you get the redder your skin turns and also your heart rate increases as this happens.

Answer 4

Your skin turns red because your blood pressure raises when you get more active and the heat of your body would also show that way. They are many reasons if you get real sick after wards or you start getting real bad headaches I would discuss it with your Doc.

Answer 5

My mom had this problem. It turned out a medication she was on caused her not to sweat very much. It could mean you need to drink more water, or perhaps you take something that causes you to sweat less than normal. Either way, it is not exactly healthy. It is normal to be a little flush with exercise, but not beet red.

Answer 6

your body temperature changes and your body needs to get rid of the excess heat. Your capillaries in your blood dialate and get bigger so that more blood flows through them and it comes in closer contact with the skin so that it transfers the heat away from the body. That is why you are red, is because the blood basically is closer to the skin.

Answer 7

Because you are running, you get sweaty and over heated. So your skin will become flushed. Especially if out in hot weather.

Answer 8

Because when you run, you need energy all over your body. In order for your body to make energy(ATP), you need oxygen to perform cellular respiration, which makes the energy. Blood is just like a vehicle that transports oxygen to other parts of the body. You see the oxygen is attached to blood via hemoglobin. The blood is just rushing to other parts of the body where oxygen is needed to make ATP/energy so that you can continue running. Get it.

Answer 9

The same thing happens to me. The blood is simply coming to the surface to help cool you off. It will probably not decrease as you get older.

Answer 10

lack of oxygen. just like when your face turns red when you're holding your breath. energy used for exercise takes more oxygen than normal...therefore constricting the amounts going to other places, like your skin.
