What to do about itchy skin due to low immunity

To relieve itchy skin caused by low immunity, the following measures can be taken: 1. Use mild cleansing products, bathe daily, and gently pat the skin dry—avoid vigorous rubbing. 2. Avoid skincare and hygiene products containing alcohol or fragrances; wear soft, comfortable clothing to minimize skin irritation. 3. Eat more foods rich in vitamin C, such as citrus fruits and strawberries, to boost immunity. At the same time, avoid consuming excessive spicy or irritating foods. 4. If itching is severe, use antihistamines or topical anti-itch creams under medical supervision. 5. Improve immunity through moderate exercise, adequate sleep, and maintaining healthy lifestyle habits, thereby addressing the underlying cause of itchy skin.
