How much sleep should I get?
Aim for roughly eight hours of sleep each night. Research suggests that students who get at least seven to eight hours of sleep have higher GPAs than those who get six or less. Sleep lets your brain rest and sort through all of the information that bombards you daily. It allows you to rebuild cells, refill energy stores, and retain memory.
**If you are truly pressed for time, 4 sleep cycles (6 hours) is a good consolation. Shoot for 6.5 hours in practice.
More sleep isn’t necessarily better, because it might mean that you are waking up in the middle of the 90-minute sleep cycle. We recommend sleeping slightly longer than:
- 7.5 hours (5 sleep cycles)
- 9 hours (6 sleep cycles) – Even better!
- 6 hours (4 sleep cycles) – If you are short on time.

Add a safety cushion of 30 minutes and voilà! You end up with 8 or 9.5 hours of sleep!
