  1. Because during a long sleep, the body relaxes a lot. At the same time, the tone of blood vessels is weakened. What does this have to do with headaches?

    There are no pain receptors in the brain. They are present in the blood vessels of the brain. When the tone of blood vessels decreases, the blood pressure expands and stretches them. Begin to irritate the pain receptors that send a signal to the brain and it is perceived as a headache. In fact, it hurts the blood vessels in the head from overextension.

    This is usually observed in patients with vegetative-vascular dystonia (when the vessels cannot change their tone in time to meet the body's needs). In a healthy person, after switching to wakefulness, the blood vessels also immediately return to tone and there is no headache. There are also exceptions (after overwork, regime change).

  2. My head starts to ache not from the fact that we sleep for a long time, but from the fact that we just “crush sleep”, trying to enjoy the borderline half-asleep half-awake state. Even a short lying down can deprive us of energy for the whole day
    If you wake up, then you need to get up quickly and take ablution with cool water, at a comfortable temperature. Then dry thoroughly with a towel and put on clean clothes. Moreover, the fear of leaving the comfort zone lasts just over two minutes.
    Without going into details, we can say that sleep is useful at night, especially in the first half of it. The rising sun begins to increase the fire in the body and our body begins to activate metabolic processes, which, in turn, require active blood circulation, and, consequently, the motor activity of the muscular system, especially the lower extremities. Because it is the muscles of our legs that make a very significant contribution to ensuring blood circulation.
    Stagnant processes caused by the lack of normal blood flow cause disturbances in the vital systems of the body. And headache, this is not the only problem of violation of the daily routine.
    I wish you all active cheerfulness and enthusiasm. Because it is enthusiasm that is the driving force that makes us wake up early in the morning.

  3. It all depends on how active the person is.Average activity -8 hours of sleep.That is, there is a certain ratio of sleep time and daytime activity. Too much sleep in an hour and a half does not play a big role,but three or four “extra” hours of sleep adversely affects a person. I may not have given a clear answer,but I can't say anything more clear. The only thing I can say is:there is a version according to which the entire cause of headaches after a “long” sleep is sleep apnea.

  4. What does “too long”mean? For some, 10 hours is already “too long”.�

    And in general, what, this happens? What is a headache from sleep?)))�

    I need 12-15 hours to get enough sleep, feel great and full of energy. If possible, I sleep 19-21 hours WITHOUT waking up. I've been practicing this for 9 years (if possible, �of course). On the contrary, my head hurts when I sleep 6-8 hours, wake up with difficulty, according to the alarm clock, broken and as if with a hangover. Especially when you have to “live like this” for a week or several in a row, or even a month – just terrible.�

    Is there something wrong with me?�

    PS: What was discussed in the answer of Alexander Sterligov, the VSD is also available.

  5. Rather, this happens in people who have problems with blood vessels and frequent migraines (with aura). There is only one way out, go to bed on time, get up on the weekend on the alarm clock of the working day. After waking up, be sure to release the intestines, exercise, breakfast. It is better to take a nap later in the afternoon, after lunch))).

  6. There are several reasons.Problem with blood vessels.Perhaps the oxygen supply is poor due to the tortuosity of the artery,this occurs mainly in those who suffer from cervical osteochondrosis.Also, the cause of the same hypoxia may be a curvature of the nasal septum.When we move, the blood that carries oxygen to all the organs moves in a different rhythm.There is another option, this is the clogged arteries in some people with cholesterol plaque.

  7. The causes of this ailment are not so many in fact.

    It is likely that you are sleeping in a stuffy room, because too little oxygen is supplied to the brain. In this case, I advise you to walk to work/school in the morning and get some air – it should pass.

    Blood venous outflow can also be disrupted, after which the pressure rises, which leads us again to a headache.

    When you sleep for about 12 hours, a slight brain intoxication may occur.

    In general, healthy sleep is when you fall asleep at about the same time, and wake up on your own, without an alarm clock. If you are very concerned about headaches after sleep, I advise you to consult a specialist.

    Well, if you overturned more than one glass of hot drink before going to bed, the cause of the headache is quite clear. As a way out of this situation – tip over more:)

    Sleep well, Alexander, and don't get sick.

  8. I read somewhere that this is due to hypoxia caused by insufficient gas exchange during sleep (breathing is infrequent and not deep), I may be wrong.

  9. There are many explanations – an uncomfortable position of the neck, as a result of which the vertebral artery is crushed.

    Drinking alcohol and/or a large amount of fluids before going to bed-we get a deterioration in fluid absorption, edema plus intoxication

    Oxygen starvation-if you sleep with your windows closed.

    Due to prolonged stay in a horizontal position, the outflow of blood from the head worsens, which increases intracranial pressure.
