Why do my feet itch severely at night?

Severe itching of the feet at night is often caused by fungal infection or eczema. During the day, there are many distractions, so the feeling of itching in the feet may not be noticeable. When we go to bed at night, we usually soak our feet in hot water. Fungi prefer a warm and humid environment, which can easily release inflammatory mediators, causing severe itching in the feet. It is important to treat the cause of the itching to alleviate the condition. If the feet have itchy skin diseases such as foot eczema or athlete's foot, itching often intensifies at night. This can be attributed to several reasons:

During the day, our attention is often diverted by work, study, etc., so the sensation of itching may not be too intense. At night, when it is quiet and there are no other distractions, the sensation of itching becomes more apparent.

The feeling of itching is related to temperature. Itching sensations tend to intensify when the temperature rises. At night, when our feet are covered in blankets and the temperature increases, the itching sensation intensifies.

If the itching is caused by athlete's foot (fungal infection), the warm and humid environment inside the blanket at night can promote the growth and activity of the fungus. This can lead to the release of inflammatory mediators, stimulating our nerves and causing unbearable itching.
