Why is tinea cruris more prone to itching at night?
Disease description:
My friend is 36 years old and recently developed jock itch. Today, he told me that the affected area was extremely itchy at night, to the point of preventing sleep. I would like to know why jock itch tends to cause more itching at night.

The main reasons for tinea cruris (jock itch) causing more itchiness at night are as follows:
1. **Increased fungal activity**: Fungi tend to be more active at night, possibly stimulating the skin and intensifying inflammatory reactions, thus causing or worsening itching.
2. **Heightened nerve sensitivity**: The body's nerve sensitivity is relatively higher at night, making sensations of itchiness more intense.
3. **Elevated body temperature**: During sleep at night, localized body temperature may rise due to factors such as covering with blankets. This provides a more favorable environment for fungal growth and reproduction, thereby increasing skin irritation and itchiness.
4. **Psychological factors**: Before sleep or during the night, individuals tend to be more attentive and relaxed, which may lead to a heightened focus on the sensation of itching. This psychological awareness can intensify the perception of itchiness.
