Why do my fingers swell up when I go for a jog (run)?

Question

I run 40 mins every morning and at the end of it my fingers are normally swollen. It goes away after about 20 minutes, but I was just wondering why this happens.

Answer 1

It is because of

1)Weather:
- Long walks in warm weather.
- Some walkers reported the problem more in cool weather.
- Some thought that higher altitude contributed to more swelling.
Electrolyte imbalance:Electrolytes are the salts in your bloodstream, which must be kept in balance to prevent swelling in the tissues. Sweating without replacing the lost salt can upset this balance.

Too much salt can swing you in the opposite direction and still cause swelling."If you are not taking in adequate electrolytes, the imbalance in salt levels between the blood stream, the cells, and the extracellular spaces essentially results in a trapping of the water in the tissues as the sodium is lost in sweat. The same thing can happen if you are taking in too much salt. For those interested, look up "sodium-potassium pump" in a textbook of physiology to get you started."

2) Good Hydration:One person's physician said the swelling was a sign of good hydration, i.e., of fluids being carried into the capillaries just beneath the skin to promote cooling. This swelling is more noticeable in the extremities. He didn't think it was anything to worry about.

3) Centrifugal Force:If you are walking / running properly, the centrifugal force generated by swinging your arms will gradually lead to edema (swelling) in the hands.

4) Blood Pooling: Swollen fingers/hands are due to blood pooling in the extremities of the body. Blood pooling also occurs in the feet. However, in our legs we have large, efficient muscles that are pretty good at getting the blood pumped back up to the heart. In the hands and fingers, we have smaller muscles that are not as good at getting the blood pumped back up to the heart. So, what you get is numb, tingling, swollen fingers.

Circulation isnt running through your fingertips when they are at your side. For good circulation...your supposed to keep that body part above your heart. Thats kind of hard to do (and look sane) while walking. Id keep my arms up in sort of a boxing style and sway them forward and back like you see the daily joggers do. See if that helps. You must be retaining some water.

Answer 4

You may have circulation problems. You should think about talking to your doctor about high blood pressure. That's what I had (poor circulation problems) and when I ran, the tips of my fingers felt numb, also sometimes the tips of my toes felt numb. Right now I'm on blood pressure medication, and thinks are fine for me.

Answer 5

more blood comes as a result of activity
