Why does my anus itch more at night and how can I prevent it?

Pruritus ani, or anal itching, can feel worse at night because you're less distracted and more aware of any discomfort. There are several ways to help prevent it:

1. Hygiene: Keep the area clean and dry. Gently wash with water and pat dry after using the bathroom. Avoid harsh soaps that might irritate the skin.

2. Clothing: Wear loose-fitting underwear and clothing to prevent moisture build-up.

3. Diet: Some foods can irritate the area, such as spicy foods, caffeine, and chocolate. Try to notice if certain foods make the itching worse.

4. Avoid Scratching: Scratching can make the itch worse and even cause damage to the skin.

5. Moisture Control: Use a soft, absorbent cloth or unscented tissue to keep the area dry.

By following these steps, you can help reduce the chance of itching and improve comfort at night. Seek medical attention for persistent itching as this can sometimes be a sign of pinworms.
