If Americans were given a grade for sleeping, they would have earned a C last year.
The SleepScore Million Nights Survey, created by Dr. Mehmet Oz, ResMed and Six Senses Hotels Resorts Spas and launched in October 2016, collected 1.5 million nights of sleep data from Americans. The results, presented at the International Consumer Electronics Show 2017 by SleepScore Labs, gave the country a sleep score of 77.
- Most don’t get the recommended amount of sleep—79% reported getting seven hours or less.
- Women average 24 more minutes of sleep than men.
- The mattress matters. Sleeping on a good mattress adds up to 20 minutes of sleep a night.
- Americans lost sleep the day of the U.S. election and the day after.
- On average, Americans go to bed at 10:21 p.m. and wake up at 7:41 a.m.
- Exercise benefits sleep. Those who exercised 30 minutes a day tended to sleep 14 minutes longer.
- Good news for moderate drinkers—those who consumed one or two alcoholic beverages slept 16 minutes more than those who had more than two drinks or no drinks at all.
- Two or three cups of coffee don’t seem to disrupt sleep. But those who drank four cups or more slept 16 minutes less than others.
