Anal itching during nighttime sleep may be caused by pinworm infection. A classic symptom of enterobiasis (pinworm infection) is anal pruritus, which typically worsens at night. This occurs because female pinworms migrate to the perianal region during the night to lay eggs and secrete substances that can irritate the surrounding skin, thereby triggering intense itching.
