If the symptoms of a cold are mild, you can take a hot bath, but you should pay attention to the temperature and duration of the bath, as well as keeping warm afterward. If you have high fever, severe dizziness or fatigue, it is recommended that you wait until your symptoms improve before taking a hot bath. 1. Bathing temperature: Although the water temperature should not be too low when you have a cold, it should not be too high to avoid burns. At the same time, high water temperature may cause excessive expansion of capillaries, dizziness and even fainting. 2. Bathing time: When you have a cold, it is not recommended to take a long bath. Because the environment is relatively closed when taking a bath, the temperature is high, which is not conducive to the body’s heat dissipation, and will also aggravate the dizziness and other symptoms. 3. Warmth: In order to avoid catching a cold after taking a bath, you should use a towel to dry your body in a timely manner and use a hair dryer to dry your hair. Ensure that the ambient temperature is not too low, and do not face the air conditioner or fan directly. Colds require timely hydration to avoid dehydration. If the symptoms are serious, it is recommended to consult a doctor for standardized treatment.
