What is a normal sleep pattern?
Typical sleep cycle patterns change throughout our lives, too.

What is the difference between REM and deep sleep?
Your brain waves in REM sleep are closer to wakefulness than deep sleep, and your breathing becomes irregular and speeds up. Blood pressure and heart rates also increase to near awake levels in REM sleep. It’s not surprising that with so much near-wakefulness, this stage is when most of your dreaming occurs.
How accurate is Fitbit sleep?
The results of Fitbit’s study, which were scored independently by polysomnography technologists, demonstrate that these devices can be used to track sleep stages with a reasonable degree of accuracy in normal adult sleepers, according to Fitbit.
What is the best sleep pattern?
People are most likely to be at their sleepiest at two points: between 1 p.m. and 3 p.m. and between 2 a.m. and 4 a.m. The better the quality of sleep you get, the less likely you are to experience significant daytime sleepiness. Circadian rhythm also dictates your natural bedtime and morning wakeup schedules.

Deep sleep, on the other hand is likely to take up 10 to 25 percent (depending on your age) of your sleep. “There’s no real way to get too much deep sleep,” says Grandner. “Your body has its own natural drive for it, so once you meet that, the need will dissipate and you’ll just start going into REM and light sleep.”
What is the most restful stage of sleep?
Waking someone from stage 4 is almost impossible—a bit like trying to wake a hibernating bear in the middle of winter. This is the most restful part of the night’s sleep. Muscular activity decreases even further, and our eyes do not move.
