The reason behind hands and fingers swelling during walking or running

Are you one of the many who have experienced swollen fingers or hands while walking or running? This common issue is still being studied, but initial evidence points to various causes such as heat, metabolic changes, or arm movement during workouts.

When you walk or run, the natural swinging motion of your arms could be responsible for the swelling in your fingers and hands. This repetitive arm movement may create a centrifugal force that pushes fluid into these areas, resulting in post-exercise swelling.

Fluid imbalance is another potential cause, especially in warm environments. Your body responds to increased heat by increasing blood flow to the skin, leading to sweating. Some individuals may have difficulty regulating internal temperature through sweating, causing fluid buildup in the hands and fingers.

In rare cases, swelling could be a sign of hyponatremia, characterized by low sodium levels in the body. Endurance athletes like ultramarathon runners are at higher risk due to excessive water consumption before workouts, leading to fluid imbalance and swelling.

Metabolic changes during exercise can also contribute to hand swelling. As blood flow is redirected to vital organs and muscles, the hands may receive less blood, causing vasodilation and localized swelling.

To reduce post-exercise swelling, consider drinking electrolyte-containing fluids, engaging in arm movements during workouts, removing restrictive items, and wearing compression gloves. While hand swelling after exercise is generally normal, it’s essential to seek medical attention if accompanied by severe symptoms like dizziness or headache.

In conclusion, the mystery of post-exercise hand swelling is a complex issue with multiple potential causes. By understanding these factors and taking preventive measures, you can better manage this common condition and enjoy a more comfortable workout experience.
