Many people are not able to get full sleep even after sleeping for 7-8 hours, but there are some people who look fresh after sleeping for 4-5 hours. In such a situation, let us know what science works behind this, how much sleep is necessary to feel fresh…
How many hours of sleep is necessary
According to the American Academy of Sleep Medicine, everyone needs at least 8 hours of sleep in 24 hours. However, not everyone sleeps that much. Some people can complete their sleep even after sleeping for 4 hours. Regarding this, experts say that it is not the hours of sleep but the quality that is important. Deep sleep is important for completing sleep and feeling fresh even after sleeping less.
If the sleep is deep then even four hours of sleep is sufficient. Such people are called deep sleepers. Such people do not have health related problems despite less sleep. Whereas, those who sleep for 7-8 hours feel that they have not slept enough, they are called light sleepers. To understand sleep properly, knowledge of sleep cycle is most important.
What is a sleep cycle
Sleep cycle simply means the completion of the sleep cycle. It has many stages from sleeping to waking up. It starts with the onset of sleep after lying down on the bed. The hours of this stage can vary for everyone. Usually after two hours, the body starts moving from this stage to the next stage. In this, the movement of the eyes slows down and the heart rate becomes normal.
Deep sleep occurs in this stage. In this the brain remains calm and the sleep becomes deeper. The person who stays in it the most, completes his sleep despite fewer hours. There is no disturbance in this stage and dreams also do not come. The third and last stage is REM SLEEP. In this the sleep continues to be complete. The person keeps dreaming. Because of this his pupils keep moving. This stage can also last up to two hours.
What does sleep cycle mean?
Experts say that the meaning of sleep cycle is clear that if you fall asleep by 10-11 pm and wake up at 6 am, it means that you have had enough sleep. You should not sleep again after this because then the body starts going into the next stage. After this, when you wake up between 8-9 pm, your sleep is interrupted. This is the reason why some people do not feel fresh despite sleeping for 8-9 hours.
