Not enough sleep: Talk to your doctor about this & see if you need assessed for secondary insomnia (insomnia due to other organic or psychological factors) which can be treated. Meanwhile you can try the sleep hygeine techniques.

Actually yes: "normal" sleep is between 6 and 8 hours but is extremely variable. There is a statistical relationship (for sleep only) that states that longevity is decreased when less than 6 or greater than 8 hours on a regular basis. There is a record of a woman who claimed to sleep only 1 hour a night and that she was perfectly healthy. We still don't know why we sleep!
