What Is Runner’s Itch?
Runner’s itch, as the term suggests, is a sudden onset of bouts of itching or symptoms of an allergy following a run or exercise. Listed below are the most common causes of runner’s itch.
What Causes Runner’s Itch?
There are a number of conditions, allergies, and other factors that could be causing your legs to itch while running. They include:
- Exercise-Induced Urticaria
This condition is also referred to as cholinergic urticaria. It results in itchy red hives, along with other allergic symptoms. Physical activity that increases the core temperature and causes you to sweat is one of the most common causes of this condition (1).
- Exercise-Induced Anaphylaxis
This is a rare condition in which anaphylaxis occurs post a physical activity of any kind. Anaphylaxis is a deadly allergic reaction that occurs when you are exposed to anything you are allergic to. In some cases, such reactions may also be triggered by exercise or running (2).
- Cold Urticaria
Cold urticaria is an allergic reaction to cold temperatures (3). It can cause your skin to develop red and itchy hives when exposed to cold. Its symptoms may be mild or severe and may vary from one individual to another.
- Circulation Problems
In some cases, lack of running or jumping into a sprint after a long interval can cause your legs to itch. If you have not been physically active lately, the capillaries in your legs can collapse slightly. The sudden bout of exercise may need your capillaries to expand to allow increased blood flow. This expansion sends “itchy signals” to your brain, thereby causing your legs to itch while running. This condition is most likely to ease after running for a few days.
- Allergic Reactions
Allergic reactions like contact dermatitisi XA skin condition characterized by itchy rashes caused due to direct contact with an allergen or a reactive substance. or eczemai XA common skin condition characterized by inflammation, dryness, itchiness and scaly patches. Also known as atopic dermatitis. could also cause runner’s itch. If your skin is allergic to certain detergents or clothing that you have worn while running, it could develop an allergic reaction to the irritant and may begin to itch (4). Sweating while running tends to make the itching more severe.
- Dry Skin
In general, those with dry skin are more prone to itching (5). Hence, if you have xerosis or dry skin, you are more likely to experience itching while running.
Almost all conditions that trigger itchy legs can be rather easily managed by treating the underlying cause, such as the use of antihistaminesi XA class of drugs that are used to provide relief from allergies, hay fever, cold, insect bites and in some cases, short-term insomnia. .

What Can You Do To Prevent Itching?
- Warm up for at least 10 minutes before a workout or run.
- Take short intervals between any physical activity.
- If the itching is triggered by cold temperature, wear layers of clothing to cover the exposed body parts while running.
- If you experience exercise-induced anaphylaxis, opt for a less strenuous workout like swimming.
- Have a body bath daily.
- Moisturize your skin daily.
- Wear protective clothing like knee-length socks if you are living in an area with allergens like poison ivy.
- Drink water at least 45 minutes before and after your workout. Dehydration causes the release of histamine in your skin, leading to itching. Increasing your water intake can counteract this effect.
Most cases of itchy legs while running, excluding exercise-induced anaphylaxis, are not of much concern. Exercise-induced anaphylaxis can be life-threatening and needs to be treated medically immediately. The other causes can be managed quite easily by taking prescription medications for the underlying condition. Taking antihistamines and applying Calamine lotion can relieve the symptoms of itching.
