Hello: Precautions for pruritus patients: 1. Live regularly, go to bed early and get up early, and exercise properly. Increase or decrease clothes in time to avoid hot and cold stimulation. 2. Patients with systemic itching should pay attention to reducing the number of baths. Don't rub your skin excessively when taking a bath, and don't use alkaline soap. 3. Underwear should be made of cotton, which is loose and comfortable to avoid friction. 4. Relax, avoid anger and anxiety, and build self-confidence. Actively look for reasons and eliminate inducing factors. 5. Quit smoking alcohol, strong tea, coffee and all spicy and irritating foods, and moderately supplement fat in the diet. And you should also go to a regular skin specialist hospital for treatment as soon as possible.
