Fingers Swell During Exercise

During exercise like walking or running, you sometimes see your fingers and hands swell. Although this moisture retention may be difficult and uncomfortable, under almost all conditions it is a normal physiological response to exercise and is not a cause for alarm. Some people are more sensitive than others for exercise-induced swelling of the hands.

Increased blood supply
When you exercise, place a bigger question on your blood circulation and respiratory systems. As blood flow increases to your heart, lungs and muscles, it reduces in extremities like your fingers. As a result, cool your fingers and the hands, opening their blood vessels wider, resulting in edema or swelling. Vasodilation - The dilation of the blood vessels - Close to the skin happens with effort and is one of the ways the body releases heat from the blood as exercise warms your system.

Trapped liquid
Another reason you will notice swelling during the exercise that can catch liquid in your hands. Effort increases the amount of blood pumping through your body. The big muscles of your legs move vigorously in most forms of exercise, but the muscles of your arms are smaller and can not work so hard. When your upper limbs are below the level of your heart, as they are when you walk or run, gravity makes it harder for liquid to leave your hands, causing them to blow up.

Hyponatremia
Although rare, a more severe form of body cell swelling may occasionally occur at athletes to take part in demanding sporting events such as marathons. Named hyponatremia, this dangerous condition is caused by a lack of sufficient sodium in the body. Large amounts of water drink in extreme effort can cause acute disturbance of normal sodium levels. Other symptoms, including confusion, fatigue and vomiting, are apparent in addition to swelling in the hands and fingers. Everyone suspected of suffering from hyponatremia requires immediate medical attention.

Swelling management
Although there is no way to prevent edema forming in your hands on effort, you can prevent discomfort by removing rings, watches, or shirts with tight cuffs before training. As soon as you stop, the circulation and volume of fluid in your hands will return to normal soon.
