Seasonal skin allergies are allergic reactions of the skin triggered by allergens that occur during specific seasons. For example, in spring, pollen allergies might lead to dermatitis, eczema, or urticaria; in summer, the intense ultraviolet rays can cause solar dermatitis, and in the cold weather of autumn and winter, cold urticaria or allergic dermatitis might occur. These conditions only appear during specific seasons and generally ease off or disappear after the season ends without the need for treatment. These are characteristics of seasonal skin allergies. In such cases, it is advisable to regularly exercise to boost the immune system to fight against allergens, avoid spicy and irritating foods, and refrain from staying up late.
