Daytime sleep: good or bad? It would seem that most people have long defined their priorities in this matter. Anthropologists claim that the human body is genetically programmed to sleep twice a day, and encourage afternoon rest. Managers of large enterprises purchase “sleepy capsules” for their employees so that they can sleep and recuperate at work. Young people are actively involved in the struggle for the right daytime sleep at work. And thousands of people are engaged in direct practice, happy to lie down to take a nap after lunch.
A short nap during the day is called a healthy habit. However, there are situations in which he can become very harmful!
After a nap, my head hurts: why?
Findings about the possible dangers of afternoon rest are often associated with complaints from some people that they become ill after a nap. Having awakened, they feel a headache, unpleasant weakness, body aches, even nausea. Not feeling the promised surge of energy at all, they are suffering almost to the very evening, trying to concentrate on their actions while reminding a boiled amoeba.
However, to blame for the deterioration of their well-being sleep – stupid and unfair. After all, the reason why a person has a headache after a nap, is usually his own incontinence.
If you eat too well at dinner, you feel unwell. Food consumption is a physiological need, but if you overstay, the body will not like it. So it is with the rest. Pereiv sleep, a person will experience discomfort. This is due to the complex neurohormonal processes associated with sleep and wakefulness.
If you feel bad after a nap, but you need such a rest, you can give only one piece of advice: limit yourself to 20-30-minute “pouring” instead of sleeping for 2-3-4 hours in a row, contrary to the laws of human nature.
The harm of daytime sleep for the night
Excessive daytime sleep can harm not only the well-being and level of one’s own adequacy after waking up, but also health. It is proved that too long or too late daytime sleep (after 14-15 hours of the day) makes it difficult to fall asleep at night. A person who indulges his weaknesses and sleeps how much he will fit during the day, risks acquiring chronic insomnia!
Then it will not be easy to break out of the vicious circle: because of the harmful long sleep of the day, you will start to fall asleep only in the morning, because of nighttime sleeplessness you will have to go to bed for a long time … It’s better not to create prerequisites for this. The method of prevention is the same: an adjustable, time-limited daytime sleep.
The harm of daytime sleep to health
In recent years, the results of several studies on the health effects of naps have been published abroad. For example, American neurologists have found that daytime sleep in older people is associated with an increased (3-4 times!) Likelihood of stroke. English somnologists said that daytime sleep in people of mature and elderly age (assuming that the total duration of sleep per day exceeds 8 hours) is associated with a decrease in life expectancy.
All this is pretty scary, isn’t it? So does daytime sleep benefit or hurt?
Do not rush to renounce sleep in the afternoon. Please note: the above studies have studied people in the older age group. And they, as we know, are carriers of various diseases, including those that are accompanied by daytime sleepiness. Thus, it is possible that they are the cause of sleepiness are diseases, and not vice versa. For example, obstructive sleep apnea (stopping breathing in a dream against snoring, it is more and more common with age) provokes drowsiness during the day, increases the risk of strokes and shortens a person’s life …
And yet: in research on the negative impact on health, it’s not just a daytime sleep, but excess daytime sleep. He, as we have already decided, is really harmful. But a short rest is only beneficial!
When day sleep should be abandoned
There are several situations in which it is better not to use the opportunity to sleep during the day.
– No need for daytime sleep. “Sleep is the best way to spend time getting bored. He slept – and there, you see, where did the boredom go … This Mark Twain know-how cannot be considered a guide to action. Sleeping only in order to “kill time” is a waste of notorious time and a risk to acquire nighttime insomnia.
– Lack of a sense of proportion. There are people who can not resist the charms of sleep. Being set to lie down for 20 minutes, they get up after 3 hours with a headache; they feel bad and even ashamed of themselves, but they cannot do anything about it. Is it about you? Then, firstly, make sure that you are healthy (excessive sleepiness is not the norm), and secondly, it is better to avoid daytime sleep. Better to dober until the evening than to get chronic insomnia.
– Difficult falling asleep in the evenings. If you hardly fall asleep in the evenings, you are not recommended to have a day rest – there is a risk that it will become even more difficult to fall asleep at night.
So: is there any significant harm from daytime sleep? If it is planned correctly (in more detail about its organization – here), then you should not be afraid. Sleep on health!
