  1. When you go to bed late, the slow-wave sleep phase is less frequent. Neurotransmitters that inhibit consciousness, such as serotonin, are produced less. So it's easier to wake up.
    But very quickly comes fatigue and drowsiness. Literally after a couple of hours I want to sleep, as if I didn't sleep at all.

  2. my dad once said a great thing to me: “if you sleep less, you want less.” I used this rule in my sessions: instead of the usual night's sleep, I slept for three hours 2-3 times a day. but after a week, you start losing ground and going crazy. To be honest, I don't know how it works, but it's an interesting thing

  3. The later you go to bed, the easier it is to get up, there is such a thing. In fact, this is due to a violation of the circadian rhythms of sleep. It has long been proven that if you do not fall asleep in the interval (extreme interval) from 00 to 2, the body begins to produce a large number of glucocorticoids (stress hormones), in a simple way, the wrong hormones and neurotransmitters begin to predominate. Therefore, in the morning, with high cortisol, it is easier for you to wake up, but in the long run it does not bode well.

  4. The main rule is to sleep at least 7 hours. When sleeping 5-6 hours or less, statistically, the violation of insulin sensitivity increases several times, which leads to fat deposits 30% faster than in those who get enough sleep and heart attack mortality is several times higher in people who like to sleep less. Melatonin is also a sleep hormone, it is the most powerful antioxidant. This is skin protection and cancer prevention. But its production occurs from 12 to 4 o'clock in the morning, in the dark to a greater extent.�

    For this reason, experiments with sleep reduction, objectively nothing but harm will not bring.�

  5. Waking up refreshed in the morning after only 4 hours of sleep is realistic, but it is not a fact that in the middle of the day you will not feel tired and you will not need a 20-minute (at least) “reboot”.

    It is best to go to bed before 23: 00, the duration of sleep should be at least 8 hours. It is necessary to sleep in a completely dark room. You should go to bed and get up earlier. When a person falls asleep between one o'clock in the morning and four in the morning, he wakes up no one knows when. Different days require different sleep times. � �

    Sleep is divided into several phases: 1. deep sleep. The most important part of sleep. In it, the brain and the body relax, and the most intensive recovery of the body's resources takes place. Your heart rate slows down, and your body temperature drops. Brain activity is almost nonexistent. And 2. REM sleep phase. In this phase, the pupil of the eye runs madly back and forth under the eyelid. There is also a rest of the body, but not as intense as in the deep sleep phase. In 95% of cases, it is in this phase that you dream.

    Our sleep consists of cycles: several phases follow each other in turn. The only thing we need to know from this is that REM sleep is the easiest time to wake up. In it, the body practically does not sleep, but is in a state of slumber. This is the phase where you toss and turn the most.

    So, the ease of waking up depends mainly on the phase of sleep, not its quantity.�

    Waking up in REM sleep is much easier.

  6. since the body does not have time to finally fall asleep and plunge into the stage of deep sleep, it is much easier to get up in 2-3 hours than in the same 6 hours

  7. I don't know, it doesn't work with me. One day I decided to get about two hours of sleep before an exam, which is from five to seven in the morning, and when I woke up, I felt completely destroyed. It's like I've been hit by a skating rink. The next time I had to sit up for such a long time at night, I just didn't go to bed and I was much better than that time.
