The main causes of winter skin itching are as follows: 1. **Dry skin**: Low winter temperatures and low humidity cause the skin to lose moisture easily, leading to dryness and itching. In addition, reduced sebum production from sebaceous glands during winter further exacerbates skin dryness. 2. **Excessive cleansing**: Taking showers with excessively hot water, showering for prolonged periods, or using strongly alkaline body washes during winter can damage the skin's barrier function, resulting in dryness and itching. 3. **Environmental factors**: Spending extended periods in air-conditioned rooms or environments with very low humidity can cause skin dehydration, leading to dryness and itching. 4. **Allergies**: Contact with allergens such as cosmetics, pollen, and dust can also trigger skin itching. 5. **Medical conditions**: Certain skin disorders, such as eczema and cold urticaria, tend to worsen in winter, causing increased skin itching. To relieve itching, it is important to maintain skin hydration, avoid excessive cleansing, ensure appropriate indoor humidity, and seek medical treatment based on the underlying cause under a doctor's guidance.
