How to treat the harm of daily bathing to the body

Taking a shower every day generally does not pose any harm to the body, but excessive cleaning or improper use may cause problems such as dry skin and damaged barriers. Skin problems can be improved by adjusting bathing habits, applying moisturizers externally, and avoiding irritants. Excessive water temperature or prolonged bathing time can damage the surface oil layer of the skin, leading to increased water loss from the stratum corneum. It is recommended to keep the water temperature close to body temperature and the bathing time should not exceed 15 minutes. Apply moisturizing cream containing ceramide, urea, or glycerin within 3 minutes after bathing to help repair the skin barrier. Choose soap free weakly acidic cleaning products to reduce interference with the skin's acid-base balance. When some people have underlying skin diseases such as atopic dermatitis or psoriasis, frequent bathing may exacerbate itching and scaling symptoms. These patients need to use medicinal detergents containing coal tar and salicylic acid under the guidance of a doctor, and if necessary, use topical corticosteroid ointments such as hydrocortisone butyrate cream and halometasone cream for anti-inflammatory treatment. When combined with bacterial infections, antibiotics such as fusidic acid cream can be used for a short period of time. Maintaining regular bathing habits can help maintain skin cleanliness, but the frequency should be adjusted according to the season. In winter, it can be reduced to once every other day. Wear breathable cotton clothing after bathing to avoid friction and irritation from synthetic materials. If there are persistent abnormal symptoms such as erythema and cracking, it is necessary to promptly seek medical attention from a dermatologist to investigate potential diseases such as atopic dermatitis and ichthyosis. Daily intake of deep-sea fish rich in omega-3 fatty acids can be increased to help strengthen the skin barrier function.
