How to avoid itchy skin after sweating;

I suggest you pay attention to your diet! Vitamin intake is very important to prevent and treat skin itching, especially vitamins A, B2 and B6. Eat more foods rich in vitamin A, such as animal liver, carrots, rape, celery, eggs, cod liver oil and so on.

Patients with itchy skin should avoid spicy, greasy, seafood, coffee, cigarettes, wine and other irritating foods.

Diet should be light and eat less high-fat foods, because high-fat foods will increase the oil burden on the skin, especially the pores on the skin surface are easy to block; Eat less sugar food. Too much sugar will increase the proliferation of bacteria on the skin, stimulate the skin and cause itching.

Keeping your body clean, and not caring for hygiene for a long time will lead to the body and skin harboring filth, breeding bacteria and mites, so take a bath as often as possible and change clothes frequently.
