What causes redness and burning of the skin?

Redness and hotness of the skin may be caused by sun exposure, excitement, allergies and fever. Appropriate measures need to be taken according to the specific causes. Try not to apply topical medications blindly to avoid irritation to the stratum corneum of the skin.

1. Sun exposure: If you stay outdoors for a long time and are exposed to sunlight, your skin may become red and hot. This is a normal physiological phenomenon and does not require treatment.

2. Excitement: If your mood fluctuates too much, such as being overly nervous, the blood circulation in your body will speed up. If more blood flows to the brain, your skin will feel red and hot. The symptoms will recover after your mood stabilizes.

3. Allergy: If the skin is exposed to the outside for a long time and comes into contact with allergens, or if you eat some foods that are prone to allergies, it is easy to induce allergic reactions. Not only will the skin become red and hot, but it will also cause rashes and itching. You need to take oral antihistamines under the guidance of a doctor, such as loratadine and cetirizine.

4. Fever: When the human body has a fever, the body is in a state of immunosuppression, the skin temperature will rise, and it will feel hot when touched. If it is caused by a fever, physical measures can be taken to reduce the fever, such as applying a cooling patch on the forehead or taking a warm bath.
