If you are like me, almost every morning you wake up completely rattled, as if you have not really rested and with the regular need to continue sleeping indefinitely. This happens both when you sleep little, and, inexplicably, when you sleep a lot. Popular rumors say that: if you sleep too little you don't get enough rest, that the secret of a good sleep is to go to bed early and sleep at least 8 consecutive hours, to avoid quick naps and not to sleep too much if you don't you want to wake up dazed. None of this is true and a very original and useful web application intervenes that can become a reference point to know what time to go to bed, what time it is convenient to wake up and, in general, to calculate the ideal sleep hours for all those who have problems waking up fresh and rested in the morning.

The principle is very clear: no matter how many hours you sleep, you can even sleep only three hours and wake up very well ready for any activity.
The important thing is to respect the sleep cycles that last 90 minutes. This means that if you actually sleep without interruptions for an hour and a half it is better than sleeping two hours, better sleeping 7 and a half hours than 8. The ideal for a restful sleep is still to sleep for 5 or 6 consecutive cycles.
To make a precise calculation of when to go to sleep and when to wake up the next morning, you can go to the SleepyTi.me website. In the web application you have to select the desired time of when you want to wake up and then press on "Calculate". For example, if you have to go to school or work tomorrow, you can write 8.00 AM as a wake-up time.
The site will tell what time you should go to sleep to wake up well at that time and the recommended hours are: 11:00 PM or 12:30 AM or 2:00 AM or 3:30 AM.
Sleepytime warns that the proposed time is when you actually have to fall asleep. Calculated that, on average, a person takes 14 minutes to fall asleep, one must consider going to bed a few minutes before the time set by the application.
From the home page, you can immediately press the ZZZ button to know what time it would be better to wake up if you went to sleep at this time.
Furthermore, by going to the sleepyti.me/wake/ section you can specify, instead of the alarm time, the time when you plan to go to sleep and, as a result, you get the ideal time to wake up to be sure to get up fresh and immediately operational. This site tells us when to go to bed and, who has sleep problems, could really try to respect the indicated times for a few days and see if the calculation actually works.
