Cholinergic urticaria

Cholinergic urticaria is basically an allergy to sweat, so the condition is triggered when the body temperature gets too high, especially during physical exercise.

"Some of the factors that trigger itching or irritation are changes in the pH of the skin (which can expose certain parts of the body to bacteria), as well as difficulty in the complete evaporation of sweat. perspiration ", explains dermatologist Priscila Câmara de Camargo, from the Camargo Clinic.

Contact dermatitis

Contact dermatitis is also called contact eczema, an inflammatory condition on the skin that arises from contact with substances that can cause irritation or allergy.

Thus, some runners may be prone to itchy legs during running because of contact dermatitis.

Although the problem is not directly related to physical activity, running, for example, can contribute to contact dermatitis, either from the product used to wash the clothes or the fabric.
