If your skin get really itchy when you run, bike or lift weights then you could be suffering from an allergic reaction to exercises. A few people are actually allergic to exercise, and in very rare cases, a sweaty workout could be enough to kill them.

Being hypersensitive to heat or sweat a condition known as cholinergic urticaria, which is characterised by an itchy rash that appears all over her body due to a higher body temperature from sweating, exercise or hot showers. The reaction begins as a small rash on her neck similar to miniature bumps and it later spreads to her back, stomach and the legs. The tingling sensation distracts her, making her exercising uncomfortable. However, this link as an allergic reaction has become fertile ground for discussion by scientists.

Medical case studies are yet to find evidence that supports that it is caused by being allergic to your sweat.
Experts in “Exercise-Induced Urticaria and Anaphylaxis,’ say that the condition can also be triggered by the food you eat before exercise. They also found out that in rare cases, it runs in families. Itchy feeling “Cholinergic urticaria induced by exercise usually manifests approximately six minutes after onset of exercise and increases for approximately 12 to 25 minutes. Generally, urticaria begins on the upper part of the thorax and neck but may occur anywhere on the body.

The itch is caused by the body heating up through exercise. When you have this condition, histamine is released which produces a very prickly and itchy feeling in the skin. Urticaria comes from the Latin word ‘urtica’ which means stinging nettle, which describes the feeling that a person has when they are have this allergic reaction to their sweat. These heat-raising activities trigger your sweat glands to produce a chemical that causes an itchy feel

Though the itchy feeling goes away within an hour, it is important to seek medical advice to understand the triggers.

Medicine available “Antihistamines are prescribed to decrease the uncomfortable feeling. They block the effect of histamine, a chemical in the skin that can cause allergy symptoms or anti-itch salves, to ease the symptoms
Anti-allergic medicines can also be taken prior to exercise, to minimise the itchy feeling, thus enabling the person to have a stress-free exercise. In extreme reactions, swelling of the face, throat, fingers and toes can happen. In other cases, nausea, abdominal cramps and diarrhoea can also happen.
