How much deep sleep do you need?

Answer 1

Just like you need about eight glasses of water every day, you need on average eight hours of sleep. This all depends on you. If you are young, then it is normal to sleep up to 12 hours every night as younger people use much more energy, requiring more sleep.

Answer 2

Sleeping is divided into 4 stages(former 5).

1. NREM stage 1
2. NREM stage 2
3. NREM stage 3(former stage 3 and 4)
4. REM (stage 4, former stage 5)

Deep sleep or Slow-Wave Sleep is in stage 3.

Depending on your age the amount you are in every stage and total sleep time vary. A healthy adult will need 7-8 hours of sleep every night. While sleeping you will go through the stages like this:

1 - 2 - 3 - 2 - 4

5% - 25% - 20% - 25% - 25%

24m. - 2h. - 96m. - 2h. - 2h.

Deep Sleep is believed needed to contain new memories for the future. This is also the stage were your brain "reset" from the days tasks and duties.

NREM = None Rapid Eye Movement sleep
