Why do I get a headache when I take a nap for a long time? Why do I have a headache every day after

The reasons for the headache after taking a nap for a long time may be as follows: 1. It may be related to the sleep time, and too long or too short sleep time will lead to dizziness.

2. Considering that it is related to the sleeping environment, if the indoor air circulation is not good, it will lead to the brain in a state of chronic itching, and it will also cause dizziness.

3. It may be related to the sleeping position, if you sleep on your stomach, the neck is in a state of stretching, which is easy to compress the vertebral arteries, and there will be dizziness, heaviness, and even dizziness, nausea, vomiting and other symptoms.

First, most people are accustomed to taking a nap after eating at noon, when the stomach is just filled with food, a large amount of blood flows to the stomach, resulting in a drop in blood pressure, brain supply and nutrition significantly reduced, and falling asleep immediately may cause insufficient blood and oxygen supply to the brain, and headache after waking up.

Second, nap time, most people think that as long as they sleep at noon, they can achieve the effect, but experts analyze that the easiest time for people to fall asleep is 8 hours after getting up in the morning, or about 1 o'clock at noon 8 hours before going to bed at night.

Because at this time, people's alertness is in a natural decline period, and the body will be well rested than taking a nap, and if you don't take a nap around noon, then there is a possibility of headache.

Third, eating too greasy and full before napping will increase the burden of digestion and absorption on the body, and if the blood viscosity increases, it may also cause headaches after napping.

Fourth, the nap time is too long, experts believe that a healthy nap is about 30 minutes, the longest is not more than an hour, if the time is too short to achieve the effect of rest, too long to wake up, there will be a slight headache, because of the light sleep period.

Fifth, if the nap position is not right, such as sleeping on the table, it will lead to a decrease in blood supply and oxygen supply to the head, and symptoms of dizziness and headache will occur after waking up.

Clause. 1. The nap time is too long.

Usually, if the cause of headache occurs, it is more appropriate to control the nap time to about 20 minutes to 30 minutes. During this time period, the human brain is in a state of light sleep, if it exceeds this time, people will enter a deep sleep state, sleep is interrupted, and people will feel that they have not slept enough after getting up, so the mental state is not very good, so we should pay attention to developing a fixed sleep time, forming a fixed biological clock, usually waking up naturally in about half an hour, and the mental state is also better.

Clause. 2. Sleep on your stomach.

There are some office workers or students, because of the limited conditions, many times can only lie on the table at noon to sleep, such a sleeping position is easy to cause insufficient blood supply to the brain, wake up dizzy and dizzy, and the arms will also be numb, so you should try to avoid lying on the table to sleep, you can put your legs on the table to sleep, reduce the burden on the head, or buy an office special sleep pillow, there is also a certain improvement effect.

Clause. 3. Being woken up suddenly.

If you are sleeping well and are suddenly woken up by a loud noise, you will feel uncomfortable, feel that you have not slept enough, and you may even have a headache, so you should pay attention to maintaining a good sleeping environment to reduce external interference.

The reason why nap headaches occur may be related to the fact that the sleeping time is a little long, the sleeping position is lying on the stomach, and then being suddenly woken up, these three factors have a certain relationship.

Expert Q&A. What's going on with a headache after a nap.

Zhang Zhaoxu. Deputy Chief Physician.

Department of Neurology, Peking University People's Hospital.

Headaches after napping are mostly related to long naps and sleeping position.

1) Sleep time is too long: When people sleep, the heart rate will be relatively slow, the cerebral blood flow will be reduced, and it is easy to temporarily lack blood supply to the brain during napping, resulting in autonomic dysfunction, so that dizziness, headache, fatigue and other phenomena often occur when you wake up from a nap, making people feel uncomfortable and uncomfortable. In particular, if you take a nap for too long, the blood flow to the brain will be reduced, and the symptoms will be more obvious after the nap.

Secondly, people with serious disorders in the blood circulation system, especially those with narrowing of cerebral blood vessels, often have headaches when taking a nap for too long, so the nap time is generally not more than 1 hour, and the nap time is generally selected at about 1 o'clock at noon, because at this time, people's alertness is in a natural decline period, and the nap body will get a good rest at this time.

2) Poor sleeping posture: Many people sleep on their stomachs during the afternoon nap on weekdays due to environmental factors, which will reduce the blood supply to the head, and make people wake up with a series of symptoms of cerebral ischemia and hypoxia, such as dizziness, dizziness, and fatigue. At the same time, using your hands as a pillow will put pressure on your eyeballs, which will easily induce eye diseases over time, and lying on the table will compress your chest and affect blood circulation.

And poor posture can stretch the head and neck muscles, which can lead to headaches. It is best to limit your sleep to one hour at noon.

There are several cycles of sleep in the human body, from light sleep to deep sleep and then to REM period. Generally, from light sleep to deep sleep, it takes 30 to 40 minutes to produce slow-wave sleep, so now it is scientifically recommended that you try not to take a nap for more than 30 minutes.

If you sleep for more than 30 minutes in the middle of the day, you will start to sleep slowly. Once you enter a slow-wave sleep, it is very difficult for a person to wake up. The cycle is forcibly awakened without being naturally experienced, and it takes a long time for the brain waves to gradually return to a conscious state.

During the adjustment process, there will be headaches, stuffiness, and even confusion. Therefore, if you take a nap for too long, you may have this kind of headache and stuffiness. Especially in the afternoon, I feel that it is better not to sleep, because it is not easy to be awakened from deep sleep, and it takes a lot of burden for the brain to re-establish the balance of wakefulness.

Some people may have a short period of hypoxia during a short nap and sleep, so the hypoxic state may cause blood vessels to spasm, causing headaches.

Therefore, no matter which aspect causes repeated headaches during sleep, it is still necessary to pay attention. Sleep software can record the sound and frequency of breathing, first ruling out sleep apnea and hypoxia during sleep. If you want to think about other problems, you can consult a more professional sleep specialist to help solve them.

Some people will feel a headache after taking a nap, and the main reason is that they do not grasp the time when they sleep, and they sleep for too long, resulting in headaches. It is generally recommended to control the nap time to about 20 minutes to 40 minutes, if you exceed this time, you can have a headache. In addition, there are some people who cover their faces with a quilt during napping, which can also cause headaches.

Benefits of napping.

Improves memory.

After working all morning, the afternoon is usually very tiring and sleepy, and if you take a nap in between, then your physical strength will be significantly improved, and your memory will be much better. Our brains need a break, and continuous operation will reduce brain power, so napping is necessary.

Boosts immunity.

Developing a good nap habit is also very effective in boosting our immunity. Part of a person's immunity is innate, and there are also factors such as usual diet, work and rest. Pay attention to rest, take frequent naps, relieve your stress, improve the function of the immune system, and your natural immunity will increase.

Drive away bad moods.

When people are unhappy or depressed, it is easy to feel tired, so it is also recommended to take a nap when they are uncomfortable, and forget about unhappy things temporarily when they sleep, so that the brain nerves can relax a little, and the pressure will be reduced, which is conducive to relieving sad emotions. Therefore, napping has the effect of reducing stress and making people happy.

Prevention of coronary heart disease.

According to studies, proper napping can regulate the hormone balance in the body and reduce the incidence of coronary heart disease. A Greek study showed that taking a 30-minute nap at least three times a week reduced the risk of sudden death from heart disease by 37%.

There is also evidence that the incidence of coronary heart disease is much lower in countries and regions with lunch break habits than in countries that do not nap. This is due to the fact that a lunch break soothes the cardiovascular system and reduces tension in the body.

Headache after taking a nap may be caused by neurological disorders, and others may be related to weak physique, poor sleep, excessive stress, depression, depression, etc. You should develop good living habits, regular work and rest, don't stay up late, keep a good mood, participate in more outdoor sports, and strengthen physical exercise.

1.Sleeping too long: When people sleep, the heart rate will be relatively slow, the cerebral blood flow will be reduced, and it is easy to temporarily lack blood supply to the brain during napping, resulting in autonomic dysfunction, so that dizziness, headache, fatigue and other phenomena often occur when you wake up from a nap, making people feel uncomfortable and uncomfortable.

In particular, if the nap time is too long, the central nervous system of the brain will deepen the inhibition, prompting the blood vessels of the brain cells to close for too long, so that the blood flow of the brain will be more reduced, and the symptoms will be more obvious after the nap, and the people with serious disorders in the blood circulation system, especially those who have narrowed the cerebral blood vessels, often have headaches when the nap time is too long, so the nap time is generally not more than 1 hour, and the nap time is generally selected at about 1 o'clock at noon, because at this time, people's alertness is in a natural decline period, and the nap body will get a good rest at this time.

2.Take a nap immediately after a meal: Many people are used to sleeping after lunch, and at this time, the stomach is just filled with food, a large amount of blood flows to the stomach, blood pressure drops, and the oxygen supply and nutrition to the brain drop significantly.

Why do I get a headache after a nap? It can be affected by a variety of reasons, such as sleeping too long, sleeping on your stomach, getting cold or cold, and waking up too quickly, which can cause headaches after napping. If you want to avoid it better, you must do a good job of these ** effective prevention, control the nap time between 15 and 30 minutes, try not to sleep on the table, and move slowly when you get up, which may effectively alleviate this condition.

4 causes of headaches after napping.

1. Sleeping too long.

If it is more than 30 minutes, it will cause a temporary lack of oxygen in our brain, which will cause pain in the head. When this happens, it can lead to poor sleep quality and leave our brains without adequate rest. Therefore, the nap time must be controlled well, and try to keep it within 15-30 minutes.

2. Sleep on your stomach.

Many people like to sleep on their stomachs when they go to bed at noon, knowing that this posture is not good for our health. Because sleeping on your stomach reduces the blood supply to your head, you may wake up with symptoms of dizziness, fatigue, dizziness, numbness in the limbs, and cerebral ischemia or hypoxia. Therefore, it is better not to sleep on your stomach, choose a way to lie down, or you can rest on the chair.

3. Cold, cold, cold.

If the indoor temperature is too low during napping, it can cause a cold, which causes our cerebral blood vessels to constrict strongly, and the blood flow is constantly decreasing, which will cause us to wake up with a headache. Therefore, when taking a nap, you must keep the indoor temperature not too low, if the indoor temperature cannot be adjusted, you can cover a piece of clothing on your body to prevent cold, causing cold and moisture to enter the body.

4. Getting up too quickly.

Some people wake up as soon as the alarm goes off during a nap, and this quick way of getting up can also cause headaches, and sometimes even feel dizzy and dark in front of the eyes. So do it slowly when you get up, not too fast, as this is not good for your health and must be avoided.

Napping is good, but be careful not to sleep too long and not to sleep on your stomach, so that you will have a headache when you wake up.

Resting at noon is generally about 30 minutes is the best time, after sleeping for a long time, the brain blood supply is insufficient, and after getting up, you will naturally have a headache, and on the contrary, you will feel muddy and nightmare, and you will have no energy.

The nap time should not be too long, preferably around 30 minutes and less than 1 hour. If you wake up after entering a deep sleep for too long, you will not be able to achieve the effect of "relieving fatigue". A nap is different from sleeping at night, and it's definitely not as long as possible.

If the lunch break is too long, light sleep will turn into deep sleep. If you wake up suddenly or sleep in an improper position during deep sleep, it will cause transient insufficiency of blood supply to the brain, temporary disturbance of autonomic nervous system function, and the human body will feel very uncomfortable, including headache, fatigue, leg weakness and other uncomfortable feelings.

The causes of headaches after napping every day may be related to the following:

First, the first consideration is that the nap time is too long or too short, and there is no healthy regular time. Clause.

2. Caused by sleep environment factors during napping, such as excessive noise in the environment, inappropriate indoor temperature, excessive ventilation and cold, etc., the body cannot enter deep sleep. Clause.

3. Nervous headache caused by mental factors such as excessive work pressure and emotional instability recently.

It should be that the nap time is too long, the nap time is controlled in about 20 minutes to 30 minutes is more appropriate, in this time period the human brain is in a state of light sleep, if it exceeds this time, people will enter a deep sleep state, sleep is interrupted, after getting up, people will feel that they have not slept enough, so the mental state is not very good, so we should pay attention to develop a fixed sleep time, the formation of a fixed biological clock, usually to about half an hour to wake up naturally, the mental state is also better.
