Sleep cycle science: Why are you sleepy enough to sleep for eight hours?
Sleep quality looks at cycles rather than mere lengths and wakes up at the wrong stage.
The adult sleep consists of four to six cycles, each of about 90 to 110 minutes, which go through three stages of sleep, deep sleep and rapid eye movement (REM). Sleep well to repair the body, rem consolidate memories and emotions. The alarm rings during the deep sleep, and even after eight hours of sleep, it's a common reason for "sleeping enough and tired".
Use the cycle to get up.
- In 90 minutes the whole number is pushed back to sleep.
- For example, five cycles, about 7.5 hours, more sober than eight hours.
- It's more stable to get up when you're asleep. Bell
- Sleeping is mostly concentrated in the middle of the night.
Regularity affects quality recovery more than total duration. Sleep is also directly associated with metabolic and appetite: hunger rises and thinness declines when sleep is not enough, which indirectly undermines the implementation of [fat-loss-calorie-deficit] [fat-loss-calorie-deficit]. At the same time, inadequate recovery reduces the performance of training and allows for the observation of changes in static heart rate against [the introduction to the heart rate training area] (/heart-rate-training-zones). In combination with nutrition, reference is made to [the daily protein intake] (/daily-protein-intake).
How do you sleep?
In addition to the length of time, it is more important to focus on whether the day is natural and sober, whether it is possible to sleep quickly and whether it is frequent at night. A two-week sleep log search can be recorded. Overall health indicators can also be combined with a combination of [body-fat-percentage-guide] and [basal-metabolic-rate] judgement.
