Why Do My Legs Itch When I Run?

Skin That Is Easily Irritated

If you have hypersensitive skin, you may be more susceptible to runner’s itch. Itchy skin can be caused by allergies to specific soaps and detergents, fabric softeners, or clothing materials.

Sweating and dry skin can aggravate irritation.

To avoid sweaty skin, use sensitive-skin friendly laundry detergents and workout apparel made of moisture-wicking fibers. Apply moisturizer before your run to prevent dryness.

You Paused Your Run For a While

Returning to running after a few months off might be jarring. We’ve all been there, whether this is after a long run or just as a result of life being too hectic.

The flow of blood to the smallest veins in the muscles, known as capillaries, is restricted when we’re inactive.

When we resume jogging, our hearts begin to beat anew, pumping blood through all of our legs and thighs’ veins.

Capillaries enlarge to facilitate the increased blood flow, stimulating nerve endings in the nearby region. They begin to itch as a result of this.

Urticaria Caused by Exercise

Exercise-induced urticaria is an adverse response that manifests itself as itching, rashes, or redness and swelling.

Further Signs and Symptoms Include:

  • Stomach aches
  • Headache
  • Respiratory problems
  • Inflammation of the face, tongue, or hands is a common symptom.

Exercise-induced urticaria is a type of urticaria that arises during and after vigorous activity, such as jogging or trekking, particularly in hot or cold temperatures.

Vasculitis Caused by Exercise

Golfer’s vasculitis and hiker’s rash are two terms for exercise-induced vasculitis.

It’s also known as the Disney rash since it frequently occurs after being physically occupied and subjected to sunshine on a hot day, both of which are prevalent at Disney amusement parks.

On the thighs and lower legs, this inflammation disorder causes red patches, purple blotches, and swelling. Severe stinging, agony and burning accompany the itchy rashes.

You might well be predisposed to exercise-induced vasculitis due to your genetics. Within a few days, the symptoms normally disappear.  

Purpura Caused by Exercise

People who are running marathons, going long walks, or indulging in extreme physical exercise develop exercise-induced purpura. It’s very frequent in the highlands during extreme heat.

Bloodstains appear on the lower legs as a result of this illness. Skin that is crushed by socks, on the other hand, is normally unaffected. Lesions normally heal in a matter of days.

Release of Histamines

Rather than being an adverse response, exercise may cause histamine to be released to alleviate lethargy. Histamine causes your blood vessels to dilate, making you itchy.

Why Is My Runner’s Itch Still There?

While the runner’s itch is irritating, it is usually not a reason for concern.

The greatest strategy to prevent a runner’s itch and lessen its severity is to have a steady workout regimen. Itching usually stops once your body gets adjusted to activity again.

As soon as your symptoms start, try to slow, take breaks, or avoid exercising.

If your runner’s itch is persistent and not improving with medication, you might have to stop jogging entirely, especially during the summer.

How To Prevent Runner’s Itch?

Keep Yourself Hydrated and Moisturized

Hydration is the general principle of running, as every runner understands. You must be well hydrated for a variety of reasons to complete our workouts and events.

Drinking adequate water affects the skin in terms of providing the moisture your body demands. Healthy skin requires a healthful, well-hydrated system

Keep in mind that your hydration levels are influenced by your diet. Even though you’re drinking ample water, if you’re not eating well, you can become dehydrated.

The biggest factor is salty foodstuff. A high-salt diet can dehydrate you significantly.

Apply moisturizer daily, particularly in winter. During the wintertime, it’s easy to recall to moisturize your face and hands. Applying it to your legs regularly will keep your skin supple and prevent itching.

Buy New Running Gear

It could be time for a change if your itch is triggered by slacks that are too tight, a chafing waistband, or even poor-quality long socks.

Why Do Legs Itch So much In The Winter?

If you bathe once a day, be mindful. Excessive showers can remove part of the body’s natural oils, leaving it dry and irritated.

Another problem, particularly during the chilly colder months, is dry air. When it’s cold outside, there’s less humidity, which means there’s less moisture in the air, which means it’s dryer.

You lose most of your moisture via respiration, and you seldom feel like drinking water in the cold. In the wintertime, recharging is a challenge, leaving you parched and leading to dryness.


Runner’s itch is typically a minor irritation that doesn’t require medical attention.

Running consistently, using antihistamines, and limiting triggers like particular meals and beverages can all help stop runner’s itching.

If you have a runner’s itch, delay or prevent running for a while. If your condition is severe or does not improve to treatments, check with your doctor.
