Sleep : 7 to 8 hours is good. Good Luck

Depends: The sleep requirement varies with age, physical & mental activity levels. Infants start at 14h/d decline to 8-10 in mid childhood & increase in puberty. In older adults with a simple lifestyle 7-8 hrs is considered good. However, issues like sleep apnea will make this less than adequate until the problem is treated.

Varies: Some need at least 6-8 hrs of sleep each night. Others may get by with only 4-5hrs and others may require more than 9 hrs. Eights hrs may actually be too much for you. You may try to experiment with different time periods to see what your body needs. Sleep many be interrupted by episodes of apnea (breathing stops for a few moments), this would make you feel tired, no matter how long you sleep.

When counting how many hours of sleep you get do you start from the time you lay down?

No: Start timing from the time you sleep. Insomniacs can lay awake in bed for hours, but that doesn't give restorative sleep. If you have sleep problems, talk to your doctor for tips. Sleep is so important for weight, growth (in kids), immune system function, memory/learning, behavior, and more!

Yoga: What helps me when my mind is racing and i'm trying to fall asleep is to try to picture a white light and breath deeply and slowly while mentally repeating the phrase "white light". This is sort of like a yoga mantra and it works!

Normal hourse sleep: Sleep at 90 is studied as is sleep throughout ages. There is less deeper sleep as we age. The amounts are roughly the same 6-8 hours. Elderly people it may be normal to go back to napping in the day to make up for sleep disruption at night (one or two short naps > 1 hours). In 13 yr old the amount is about the same as 6-12 yr old (range between 9-12 hours of sleep) but the cycle is delayed.

Not week, night: Most adults do best with 7 - 7 1/2 hours of sleep per night. You can cut it a bit short and make up for it on weekends, but that's not near as good as that solid 7 every night.
