Barring any mildew or mold growth on your neglected workout clothes, it’s likely the itch is related to an exercise-induced histamine response. Histamine is a substance found in the body that’s most commonly associated with allergic reactions, itching, and inflammation. But researchers are just beginning to understand that histamine also plays a role in exercise.  Previously, a popular theory on exercise-induced itchiness had to do with blood vessel expansion, or vasodilation. The body expands blood vessels during exercise to help bring more oxygen and nutrients to working muscles, and to eliminate carbon dioxide and waste products. The idea is when blood vessels expand after a period of relative inactivity, the surrounding nerves, unused to the phenomenon, mistakenly register the expansion as itchiness. The problem with that theory: “I’ve read no studies that support that,” says Stanford exercise physiologist Dr. Anne Friedlander. However, new…

If you exercise regularly, your brain gets accustomed to the signals and starts to ignore them.Related: Why Scratching an Itch Only Makes It WorseBut the longer the break…

Causes of Itch During Exercise – Verywell Fit

5 Common Causes of Itch During Exercise Most itches are not problematic and will often have no recognizable cause. However, in some cases, an itch will develop whenever you engage in strenuous physical activity, such as exercise. While annoying, it is rarely serious and will usually resolve soon after you finish working out. There are cases, though, where an itch can become so intrusive that it interferes with your ability to exercise. At other times, a sudden acute itch may be the first sign of a potentially life-threatening condition known as exercise-induced anaphylaxis (EIA). What Is an Itch? An itch, also known as pruritus, is a general sensation arising from the irritation of skin cells or nerve cells associated with the skin. The sensation occurs when nerve endings, called proprioceptors, are stimulated by infection, injury, chemicals, temperature, or the body’s own immune response. When proprioceptors are stimulated, they deliver messages to the brain…
