The analysis also found over 30% of adults reported an hour of sleep debt -— when you sleep less than your body needs — while nearly 1 in 10 adults had a sleep debt of two hours or more.
“This is a well done study examining a very large and representative sample,” said Dr. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota.
Social jet lagIn addition, nearly half of the adults in the study reported social jet lag – a bad fit between the sleep timing preferred by a person’s inner biological clock and the one dictated by society.
Over 46% of the survey participants reported at least 1 hour of social jet lag, while 19.3% experienced at least 2 hours.
Untreated social jet lag can have serious consequences, including insomnia, early waking or excessive sleepiness, daytime fatigue, difficulty concentrating, constipation or diarrhea and increased cortisol levels.
