How to use iPhone's Bedtime mode
The iPhone's "Bedtime mode" within the Clock app is an innovative and interesting feature.
Working on the basis that being consistent with the amount of sleep you get (i.e. going to bed and waking up at the same time every day) is better for your health, iPhone's Bedtime mode helps make that goal easier to achieve.
If your iPhone does have iOS 13 or earlier, however, Bedtime mode is ready to roll. Here's everything you need to know about using iPhone's Bedtime mode — from getting started with the feature and analyzing your sleep results to learning how to turn off Bedtime mode and more.
So, how much sleep do you need?
If you've never really thought about it before, it can be hard to guesstimate exactly how much sleep your body needs.
While everyone is different, there are some general guidelines, based on age, to help you come up with a figure. The guidelines, published in Sleep Health: Journal of the National Sleep Foundation, were penned by a panel of experts that looked at 320 studies on the matter.
Teenagers (ages 14-17): 8-10 hours
Young adults (ages 18-25): 7-9 hours
Adults (ages 26-64): 7-9 hours
Older adults (ages 65-plus): 7-8 hours
It's worth taking these guidelines seriously, as getting yourself into long-term "sleep debt" has been linked to obesity, diabetes and cardiovascular disease. That's why iPhone's Bedtime mode comes in handy.
