Why do my feet itch when it's hot

If your feet itch in hot weather, it may be caused by skin metamorphosis due to high temperature stimulation, or it may be caused by fungal infection or allergic reaction.

1. High temperature stimulation: If the weather is hot, the temperature inside the shoes is relatively high, which will stimulate the skin allergy and cause itching symptoms. It will also cause tinea pedis, and the skin often shows symptoms such as dryness, peeling, and cracking.

2. Fungal infection: If the weather is hot in summer and you do not pay attention to the cleanliness of your feet, usually after your feet sweat, the sweat is not discharged in time, which will cause bacteria to breed in your shoes. It is easy to be infected by fungi, leading to athlete's foot, which causes symptoms of itchy feet.

3. Allergic reaction: If the weather is hot, the temperature of the feet rises, and acetylcholine is released in the body, which will stimulate the degranulation of mast cells and release allergic mediators such as histamine and leukotrienes, leading to symptoms of skin itching.

If the itchy feet are caused by fungal infection, you need to use antifungal drugs for treatment under the guidance of a doctor. At the same time, you should pay attention to the cleanliness and dryness of your feet, wear more breathable shoes, and do not scratch with your hands during the treatment, otherwise it will cause inflammation and infection. At the same time, avoid using too hot water when washing your feet, and do not eat seafood, beef and spicy foods.
