What causes itchy skin in winter?

The main causes of itchy skin in winter include the following: 1. Environmental factors: Cold winter weather and low humidity cause the skin to lose moisture, making it dry and prone to itching. 2. Human factors: Excessive bathing, using highly alkaline soaps, or washing with water that is too hot can strip the skin of its natural oils, worsening dryness and itchiness. 3. Medical conditions: Certain skin disorders such as psoriasis and eczema may worsen in winter due to dry skin, leading to increased itching. 4. Allergic reactions: Allergies to cold air or exposure to certain allergens can also trigger skin itching during winter. To relieve winter-related skin itching, it is recommended to keep the skin clean, use moisturizers appropriately, avoid excessive bathing and harsh skincare products, and take care to stay warm and protect the skin from irritation. If necessary, seek medical attention promptly for professional treatment.
