Why Do We Need Sleep?
Unless a person gets enough sleep, his performance is likely to be sadly lacking. Not just sexual performance either. Work performance, creativity, reaction time, and mood all become worse when we're tired. Although it's not entirely clear why we need sleep, the effects of sleep deprivation justify trying to get enough.
How Much Sleep Do We Need?
The amount of sleep needed depends upon the individual and their age. Some people manage on four or five hours of sleep a night. On average seven, eight, or nine hours of sleep a night is what the majority of young and middle aged men need to stay bright-eyed and bushy-tailed during the day. As we get older we tend to need less sleep. For peak performance during the day about four or five 90-minute sleep cycles are needed to rest and re-charge the brain. Each cycle combines deep sleep that brings rest, and REM (Rapid-Eye Movement) sleep during which it's believed brain chemicals are released that help tasks such as learning to be performed more easily.
Are You Getting Enough Sleep?
If you can answer 'no' to all of these then you are probably getting enough sleep:

Are You Getting Enough Sleep?
If you can answer 'no' to all of these then you are probably getting enough sleep:
- Do you sleep longer than usual on the weekends?
- Do you feel drowsy or nod off during the afternoon?
- Do you fall asleep within around 5 minutes of being in bed (It takes people who are getting enough sleep around 10-20 minutes to fall asleep)?
- Go to bed and get up at the same time everyday, including your days off.
- Keep your bedroom for sleep and sex, not work and TV.
- Avoid heavy meals, caffeine, nicotine, and alcohol for 3-4 hours before going to bed.
- Don't exercise within 3 hours of bedtime.
