Legs often itch when walking, especially if you're not accustomed to regular exercise, because of increased blood flow stimulating nerves surrounding your capillaries.
The Science Behind the Itch
When you start walking, your muscles require more oxygen. To meet this demand:
- Arteries and capillaries in your muscles expand.
- This expansion allows for increased blood flow.
If you don't exercise frequently, the nerves around these capillaries aren't used to such rapid expansion. This overstimulation of the nerves is often interpreted by the brain as an itching sensation.
Factors Contributing to the Itch
Here's a breakdown of why this is more likely to happen to some people:
- Lack of Exercise: Infrequent physical activity means your capillaries are less adapted to the expansion required during exercise.
- Nerve Sensitivity: Some individuals may have more sensitive nerves around their capillaries.
What Can You Do About It?
The good news is this itching sensation usually diminishes with regular exercise. As your body adapts, the nerves become less sensitive to the increased blood flow. Here are some tips:
- Start Slowly: Gradually increase the intensity and duration of your walks.
- Regular Exercise: Consistent physical activity helps your body adapt.
- Moisturize: Dry skin can exacerbate itching.
- Avoid Irritants: Wear comfortable clothing that doesn't irritate the skin.
