1 градус по Кельвину
Вот какой совет по сну дал мне "Калькулятор сна" (sleepyti.me/). Для того, чтобы проснуться в 7.30. Я должен лечь спать в:
10:30 PM or 12:00 AM or 1:30 AM or 3:00 AM
Please keep in mind that you should be falling asleep at these times.
The average adult human takes fourteen minutes to fall asleep, so plan accordingly!
sleepyti.me works by counting backwards in sleep cycles. Sleep cycles typically last 90 minutes.
Waking up in the middle of a sleep cycle leaves you feeling tired and groggy, but waking up in between cycles lets you wake up feeling refreshed and alert!
