10 Symptoms of Head Lice

6. Difficulty Sleeping

Lice are nocturnal feeders, meaning that nighttime is their most active period. This is when they are most likely to feed on dead skin cells as well as lay eggs. The resulting activity makes it difficult to get sleep because the patient is often tormented by constant itchiness and desire to scratch their scalp. A burning feeling or a biting feeling may also be experienced, which further contribute to sleeplessness. Smaller children especially like to be affected by this, because their scalps are more sensible. They're also more prone to getting lice in the first place.
