Why do extreme temperatures (hot and cold) make sore muscles feel better?
In: Biology
When you workout, for example, your muscles produce a lot lactic acid as a product of burning sugars to release energy. That’s why sometimes you can feel the pain flowing to nearby parts of your body. This is when you want to use cold water, because this will improve circulation and help to remove the latic acid from the muscle. After that you want to use hot water, because it will help you muscle to relax. Relaxing helps it to not be so tense and not hurting all the time. The way is more or less like that: hurt? Yes. Go cold. Then go hot.
