People who have a snoring problem tend to appear less attractive, youthful and alert than restful sleepers.

The researchers found that while people with snoring problem were rated to be ugly before the treatment, they appeared more attractive after being treated for apnoea and were also found to have fewer wrinkles following the treatment.
“The common lore, that people 'look sleepy' because they are sleepy, and that they have puffy eyes with dark circles under them, drives people to spend untold dollars on home remedies. We perceived that our CPAP patients often looked better, or reported that they'd been told they looked better, after treatment. But no one has ever actually studied this”, Dr Chervin said.
