Do you often feel tired in the morning even though you've been in bed for seven or eight hours the night before Like many people,you are not sleeping as much as you think you are 21.There is no specific number for efficiency that's been proven as linked to poor health However,according to a New York Times report about sleep quality,some experts estimate a rough number of 83 percent or above as a decent place to be:
22.Avoid blue light at night.Short wavelength blue light,sent out by the sun and by the screens of computers,iPods and smart-phones,makes you feel more alert.Blue light
tells your brain it's daytime.
23.You can also try installing apps that can filter(过滤)blue light on your devices.
24..Go to bed and wake up at relatively the same time.Consistency(连贯性)is key to a good night's sleep,especially when it comes to waking up.When you
have a regular wake-up time,your brain gets used to this and moves through the sleep cycle in preparation for you to feel rested and alert at your wake up time.Roughly an hour before you wake,hormone levels increase gradually,causing you to become more alert.
Take naps One of the biggest peaks in melatonin production happens during the 1 to 3 pm time frame.
25..If you aren't getting enough sleep at night,you're likely to feel an overwhelming desire to sleep in the afternoon.When this happens,you’re better off taking a short nap than resorting to caffeine or strong tea to keep you awake.A short nap will give you the rest you need to get through the rest of the afternoon,and you'll sleep much better in the evening than if you take a long afternoon nap.
