Place a humidifier in your room to manage humidity. The optimal humidity level for winter is considered to be 40% to 60% for comfort. If the humidity is too high, it can cause mold and dust mites, and if it's too low, viruses like the flu can become more active, making it easier to catch a cold and causing dry throats and skin. Since the air tends to dry out in winter due to air conditioning and heating, maintaining proper humidity with a humidifier or indoor drying can help you spend the winter comfortably. *This is a used item, so please understand this before making a purchase.
