Ideally, you should avoid using the computer and TV for an hour and a half before you want to go to sleep. If that is impossible, then the Zzz glasses can help offset the impact of the light and allow you go to sleep after being exposed to light. They also have yellow colored light bulbs which block the blue light. Jeffrey says the solution to this problem can even be relatively inexpensive--turn down the lights! Sleep and the disruption of the circadian cycle may be a factor in everything from postpartum depression to cancer to obesity.
Adults need to get seven and a half hours of sleep per night. Kids ages 5 to 12 need 9-11 hours of sleep. Of course, everyone is different and you can tell you have gotten enough sleep if you wake up naturally without an alarm clock.
