What you need to know before bedtime - the Big 3 of sleep

Seven to nine is the number of hours of sleep recommended for most adults. If you're thinking, 'That's not me', the doctor says you might want to make some changes. 

How do you feel when that alarm wakes you up? Here's the problem - many of us don't go to bed alone. We've got our phone, tablet or TV keeping us company. 

Ninety percent of people have screens they use in their bedroom within an hour of going to bed," said Dr. Meeta Singh, Henry Ford sleep doctor. "And that actively suppresses your melatonin."

Dr. Singh says figuring out your bedtime is simple math. 

"You count eight backwards from the time that you have to wake up and that's your bedtime," said Singh. "That will make sure you get eight hours in bed."

Getting those eight hours isn't quite so simple, but here are the big three when it comes to your sleep: quantity, timing and quality. 

"You need a certain number of hours to feel rested the next day," Singh said. "So that's number one, is the number of hours of sleep.

"Number two, the timing of sleep is important."

Sleep quality means making sure your room is dark, there are no screens, you're not full of caffeine or alcohol.
