Scientists claim that sleeping twice a day for an adult is the norm. There is the same benefits of daytime sleep for men and women of different ages, as well as children. The need is caused by the biorhythms of our body. The metabolic rate also changes. So, experiments were carried out that showed the following property of the human body: from 13 to 15 o'clock in the afternoon, the human body temperature decreases slightly. Moreover, this does not depend on whether he ate or not, as well as how much he slept at night.
A moderate afternoon nap is undoubtedly beneficial. And it manifests itself in the fact that the general condition of the body improves. A person feels more cheerful, full of strength and energy.
Is he as good as scientists say? The answer is definitely yes. Firstly, concentration of attention increases by 30-50%. Secondly, efficiency increases. In addition, mood and general well-being are definitely improved. A short nap provides a burst of energy and reduces irritability.
In the article "Napping to modulate frustration and impulsivity: A pilot study" by scientists from the Department of Psychology at the University of Michigan, it is said that half an hour's nap is the most effective measure in combating sleep deprivation and fatigue. It helps to strengthen the immune system, add positive emotions, increase the level of patience and reduce impulsivity.
But I have a long-term habit of sleeping during the day. From half an hour to an hour.
And I always adjust my rhythm of life to this iron rule for me.
And I always feel great.
Even if I sleep a whole day an hour, I wake up easily and without any problems I turn back into a vigorous working regime.
Daytime sleep allows me to work actively all day, and I still have strength for sports in the evenings.
What about siesta? In the Arab countries and in Spain it is not only an hour's rest, but also a dream. True, according to statistics, they have a decline in productivity.
It is useful, and even very much, but under certain conditions:
1) You sleep well (ideally, or at least normally) at night.
Because there is no way to compensate for night sleep with daytime sleep. Even if you generally transfer the entire night's sleep to a day (people with this way of life decently harm their body and sooner or later catch health problems, very systemic).
2) You have no difficulty falling asleep at night.
Because otherwise naps can further complicate your insomnia problems. In this case, you must first deal with it, and then think about daytime sleep.
3) You will sleep approximately between 13 and 16 hours of the day (not all 3 hours, but within this interval) ...
I strongly advise against going to bed later - it’s easier, if the situation allows, to hold out and go to bed early for the night.
4) You will sleep no more than 20-25 minutes.
Actually, the time will have to be selected experimentally, but plus or minus it will be like this. The fact is that further the person falls into a deep sleep, and this cannot be done categorically during the day - you will pull yourself out of deep sleep and you will feel twice as bad as before. Brokenness, headache and weakness are attached. There is, however, an option to sleep for more than an hour (seemingly about 90 minutes) in order to sleep off the whole cycle and not pull yourself out of deep sleep. Everyone needs to find the exact time based on their own experience.
In principle, there is still debate about the benefits and dangers of naps, but most scientists agree that naps can be very beneficial to health, it has been proven to increase efficiency, concentration, attention, and so on. but all this is subject to all of the above rules. Incorrect daytime sleep can only harm (for example, too long daytime sleep for more than 20-25 minutes, but less than a full cycle, on a regular basis leads to problems with the cardiovascular system and, according to some studies, significantly increases the risk of heart attacks and other serious heart diseases) .
If in science, then daytime sleep does not replace nighttime sleep. Its plus is, basically, restarting some internal processes. Biorhythmically - it is good to sleep when the production of melatonin reaches high values; in a healthy ordinary person, these values increase at night, in the dark. Man, biologically, is a daytime creature. We are accustomed to sleeping at night and being active during the day. For young children (taking into account their general activity during the daylight hours), it is really physiological to sleep during the day and then it is quite easy to fall asleep at night. It is physiological for an adult to spend about 14 hours a day awake without interruption.
In short, if for you sleep during the day is a way of life / the only option for rest - then sleep.
If you want to "heal" the body in this way - do not overdo it. You can disrupt your biorhythm, thereby exacerbating the state of anxiety and fatigue.
Sleep is generally useful if it is not too much or too little. It is not so important when you sleep, of course, the body is more adapted to sleep at night, but it is important to maintain a certain number of hours of sleep per day, that is, if you slept at night 4 hours, and sleep another 3 in the afternoon, then it will be better than not sleeping, and if you slept for 8 hours at night, and still sleep in the afternoon for 3 hours, then it will not be very useful, and your state will not be so cheerful, as before daytime sleep, draw conclusions from here.
