English sleepyti.me
The service helps to wake up fresh and vigorous.How it works
- I have to wake up at ... - here we set the rise time.
- Click CALCULATE and you are offered options when it is better to try to sleep.
The bottom line is that we have several stages of sleep (we all know, it happens that it lays down for a minute, and I slept an hour, or it seemed like an hour slept, and a minute passed).
When you wake up in the middle of a sleep cycle, you feel tired and shaky, but waking up between cycles wakes up a feeling of cheerfulness and vigor.
Such a principle.
