Swelling

Mine do. Can't even get my ring off after cardio, especially if it's hot out! Someone told me it could be excessive salt in diet. I do eat string cheese almost every day...

Nothing should be swelling during, well, anything. As someone else said, get that checked out by a doctor. It may be something as simple as too much sodium in your diet and not enough water and potassium, but it's best to get the serious stuff ruled out first. How much water (plain water, nothing added) do you drink on a daily basis?

Mine also swell sometimes when I do cardio - especially if it is really hot.

Q: Why do my hands swell when I do cardio?

A: According to Mayoclinic.com: Hand swelling during exercise is a fairly common problem. Unfortunately, the cause isn't so clear. It may be due to an exaggerated response by the circulatory system of your hands and fingers. Hand swelling during exercise is unlikely due to drinking excess water, electrolyte imbalance or weather.

Usually, when you exercise other parts of your body, your heart redirects blood from your hands to exercising muscles. This cools the skin and local tissues of the hand. The blood vessels in your hand try to maintain circulation but may overreact, leading to a local increase in blood and possibly swelling.

There is no proven method for preventing or reducing hand swelling during exercise. However, anecdotal evidence suggests that the following tips may help some people:

Before you exercise, remove your rings and loosen your watchband. During exercise, do occasional forward and backward arm circles. In addition, occasionally stretch your fingers out and then make a fist. Repeat this several times during exercise.
