It is very important for you to complete recommended sleep cycles until your wake up time. Make sure a minimum of 4 sleep cycles between your bedtime and wake up time.
The number of hours is not the same for every other person belonging to a different life stage. Where an adult needs to sleep for 7 to 9 hours daily, children or newbies need more time to sleep. Look at the following table to check how many hours you should sleep daily:
|Life Stage||Age Range||Recommended Sleep Hours|
|Infant||4–12 months||12-16 hours (including naps)|
|Toddler||1–2 years||11-14 hours (including naps)|
|Preschool||3–5 years||10-13 hours (including naps)|
|School-age||6-12 years||9-12 hours|
|Teens||13-18 years||8-10 hours|
|Adult||18 years and older||7 or more hours|
However, the following table gives you an idea about different wake up and sleep timings corresponding to different sleep cycles:

Using our sleep cycle calculator is quite easy and fast! It involves the following steps to go by and get sleep or wake up times in moments.
For an adult normal individual, one sleep cycle consists of 90-120 minutes of sleep. Our sleep cycle calculator also considers the same cycle range to suggest you better bedtime and wake time.
NREM stands for Non-Rapid Eye Movement Sleep and involves the first 3 of the total 4 sleep cycles. In the first 2 cycles, the brain and body gradually slow down. In 3rd phase, you run into a deep sleep.
REM stands for Rapid Eye Movement Sleep in which your body is paralyzed temporarily. In this last sleep cycle, the activity of the brain increases, and your eyes move all around behind the lids. It mostly happens near to wake up time. You can also calculate your wake up time by entering your bedtime in the REM sleep calculator and judging if any such issue happens to you.
Yes of course! As we mentioned earlier, everyone has different sleep cycle lengths. So you need to optimize your sleep to stay energized after you wake up.
