A Good Night’s Sleep

When the morning sun looks in through your bedroom window, do you jump out of bed? 1.    An adequate amount of sleep can make the difference between a great day and a terrible one!

A good night’s sleep doesn’t just happen. You need to prepare for it. 2.  First, go to bed at the same time every day, and get up at the same time. If you haven’t gotten a good night’s sleep, don’t oversleep the next morning. Get up at your regular time. Sleeping late for just a couples of days can change your body clock to a different cycle. You don’t want that if you have a set daily schedule.

Also, avoid big meals at night.   3.  Your stomach works hard to digest those fatty foods, and that may keep you up.

Your body produces a chemical called melatonin (褪黑色素) that helps you sleep. Light affects the amount of melatonin your body makes.   4. So at night turn off your TV and computer. Also, don’t read from a backlit electronic equipment like an IPad. Some scientists think that the light from those stops your body from making melatonin. So turn those screens off at least an hour before bedtime.

Maybe you can’t sleep or you wake up in the middle of the night.   5.  Get up and do something relaxing elsewhere. Then go back to bed when you feel asleep again. If you worry a lot, make a list of things you need to do the next day. Do that an hour before bed. That way you get your worrying out of the way before you go to bed.

A. Don’t just lie in bed.
