Although scientists still puzzle over why sleep is necessary, one thing is certain: We cannot survive more than a few weeks without it. When we are denied good, restful, sustained sleep on a regular basis, our brains falter in concentration, learning, memory and alertness. That’s no matter how much coffee you might guzzle.
Most adults require seven to eight hours of sleep each night.
If you have trouble sleeping, here are a few tips:
- Don’t eat a heavy meal late in the day.
- Avoid caffeine and alcohol late in the day.
- Get regular exercise, but not close to bedtime.
- If you can’t fall asleep or wake up in the middle of the night, get up and read or watch TV until you feel drowsy.
- If you lie awake worrying about things, make a to-do list before going to bed.
