Frequent bathing in winter may lead to skin dryness, barrier damage, and other issues. Excessive cleaning can damage the oil layer on the surface of the skin, increase the risk of skin sensitivity, and have a more significant impact on the elderly, infants, and patients with skin diseases. In winter, the temperature is low and the air is dry, leading to a decrease in sebum secretion on the skin. Frequent use of hot water for bathing can accelerate the loss of oil on the surface of the skin, causing a decrease in the moisture content of the stratum corneum, resulting in dryness, itching, and even flaking. Middle aged and elderly people with decreased sebaceous gland function are more prone to developing hypolipidemic eczema. Rubbing vigorously during showering can damage the stratum corneum of the skin, leading to impaired barrier function and making it easier for external stimuli to invade and trigger inflammatory reactions.
In some special circumstances, it is necessary to increase the frequency of bathing, such as after athlete training, heavy labor workers, or patients with skin infections. However, it is important to control the water temperature to no more than 40 degrees Celsius, shorten the rinsing time to within 10 minutes, and apply moisturizer immediately after bathing. Patients with skin diseases such as psoriasis and atopic dermatitis should adjust their bathing frequency according to medical advice, and if necessary, use medical moisturizers instead of regular bathing products.
It is recommended to take a shower or clean locally the next day in winter, choose weakly acidic shower gel with a pH value of around 5.5, and avoid using alkaline soap. Apply moisturizing products containing ceramide, urea, or glycerin within 3 minutes after bathing, and use a humidifier indoors to maintain a humidity of around 50%. When symptoms such as persistent skin dryness and redness occur, it is necessary to seek timely medical attention from a dermatologist.
