Got patients with skin conditions? You might ask them how they’re sleeping. A new study found that itching and burning didn’t just keep people from falling asleep, it also reduced the quality of that sleep.

‘[P]atients with skin disease experienced a feeling of fatigue more often upon waking up; periods of drowsiness during the day; tingling sensations in the eyes; and repeated yawning.’

So they might not realize the connection between being tired the next day and the fact that their skin condition is affecting them while they sleep.
