Understanding the Reasons Behind Itchy Legs While Running
Sore muscles, fatigue, and a burning sensation are common experiences during running. However, itching may also join the party!
Yes, it’s a real thing. If you’ve felt the sudden urge to scratch your legs while out for a run, you’re not alone.
Although there isn’t a formal medical term for this itching sensation during running, it’s often referred to as “runner’s itch,” as explained by Dr. Edward Laskowski, a sports medicine specialist at the Mayo Clinic. Apart from being uncomfortable, let’s explore the possible reasons behind this phenomenon.
Possible Cause #1: Starting or Restarting Your Running Routine
Dr. Laskowski suggests a few causes, and one is related to your running frequency. When you engage in physical activity, your muscles require more blood flow to receive oxygen. As you run, more blood flows to your calves, quads, and hamstrings. When you start a new running regimen or resume running after a long break, this increased blood flow can lead to itching as your body adjusts to the change.
Dr. Laskowski explains, “Your return to exercise may cause blood capillaries in arteries in your legs to dilate. This expansion can put pressure on and irritate small nerve rootlets to the skin and contribute to itching.”
With time, as your muscles develop more blood vessels to accommodate the increased demand, the itching should diminish as your body adapts to the elevated blood flow.
Possible Cause #2: Allergic Reactions
Another potential reason is an external factor. It’s conceivable that you may be experiencing an allergic reaction to your clothing or laundry detergent, especially exacerbated by sweating.
Dr. Laskowski mentions a condition known as exercise-induced urticaria, where your body reacts to physical activity. Symptoms include itching, hives, and a sensation of warmth triggered by exercise.
Tips for Managing Itchy Legs
Identifying the possible triggers is just the first step. So, what can you do about it? Firstly, check if your clothing is causing the issue by trying out different running gear, preferably sweat-wicking, and experimenting with a mild laundry detergent.
If the itching stems from the novelty of your running routine, patience is key. As your body gets accustomed to the activity, the symptoms should lessen. If not, consult your doctor or an allergy specialist for proper treatment, possibly involving antihistamines.
Dr. Laskowski recommends that “establishing a regular exercise routine is one of the best ways to prevent runner’s itch and decrease its severity.” If you do experience itching, consider slowing down or taking a break until the following day.
Resist the urge to scratch, as it may offer temporary relief but could lead to more itching due to a chemical reaction in your brain. Consider using ice or soothing creams like cortisone and aloe vera instead.
