Taking a nap can replenish your energy, but what happens when you wake up and feel weak?

When you first wake up, your physical condition is not in shape, and you have not recovered from sleepiness, so you will be tired.

The weather is hot, or if you sleep for too long, your body has entered a deep sleep, and it is difficult to recover for a while.

Because the brain is awake, but the body is still in a state of sleep, it takes a little time for the body to recover.

Normal, just fell asleep, if you don't sleep well, you will be tired, and it has nothing to do with milk.

Maybe I slept for too long, or I slept in the wrong position, but I usually don't wake up.

A short nap can refresh us and we will be tired after too long.

If you have this situation when you go to sleep, it means that you have gone into a deep sleep, and it takes a long time for the body to wake up from deep sleep.

It may be because you take a nap for too long, about half an hour to an hour.

It may be due to the fact that the nap time is too long.

A healthy nap of 15-30 minutes is the most appropriate, if it is more than 30 minutes, the body will enter a deep sleep period that is not easy to wake up, which is easy to disrupt the biological clock and affect the normal evening sleep. It should not take more than 1 hour at most, otherwise you will have soreness, weakness, and headache.

You don't have to worry, you should be fine.

Experiments conducted by scientists have shown that every day after noon 14-16 o'clock is the limit zone of the temperature curve in the human body. Taking a half-hour nap at this time is no less effective than a long night's sleep.

Although napping is necessary and beneficial, it is necessary to pay attention to the method, otherwise it will be counterproductive.

Don't go to bed after eating.

Because I have just eaten lunch, my stomach is full of food, and my digestive function is in a state of movement, such as taking a nap at this time, it will affect the digestion of the stomach and intestines, cause stomach problems, and also affect the quality of napping. It is best to rest for more than ten minutes after eating before falling asleep peacefully.

Pay attention to your sleeping position.

Many people choose to rest in the office at noon, both sitting on the chair to "sit and sleep", there are also those who "recline sleeping" on the reclining sofa, and those who are still lying on the table "sleeping". The ideal position to sleep is to lie comfortably, preferably with your head high and your feet down, facing your right side. If you sit and sleep for a long time, your brain will be deprived of oxygen, and you will be prone to dizziness, fatigue and other uncomfortable symptoms.

When people take a nap, the body is in a relatively static state, after waking up, the body cells have not yet woken up, and the blood circulation has not returned to normal, so I feel weak, drink water, and it will recover after a little activity, there is not much reason, don't be afraid.

Lunch break copy time is too long, light sleep.

When Bai wakes up suddenly after entering a deep sleep, the deeper inhibition process in the cerebral cortex cannot be lifted immediately, and the closed capillary network cannot be opened immediately, which will inevitably cause transient insufficiency of blood supply to the brain, that is, the function of the autonomic nervous system will be temporarily disturbed, and the human body will feel very uncomfortable and tired.

If the lunch break is too long, and the light sleep turns into deep sleep and then wakes up suddenly, the deep inhibition process in the cerebral cortex cannot be lifted immediately, and the closed capillary network cannot be opened immediately, which will inevitably cause transient blood supply insufficiency to the brain, that is, the function of the autonomic nervous system is temporarily disturbed, and the human body will feel very uncomfortable, tired, and sleepy.

A nap is different from sleeping at night, and it is definitely not as long as possible, it is best to take about 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".

After taking a nap, I don't have the strength to get upIt is caused by a relatively long sleep time, which causes a relatively long sleep time of fast waves.

Usually pay attention to strictly control the nap time, and go to bed only 1 hour after lunch. And the best sleep is half an hour, and the maximum should not exceed 1 hour.

You can do a routine blood test, if it is caused by a cold, you should actively ** the underlying disease, pay attention to ensure adequate sleep, usually exercise more, enhance physical fitness, the above symptoms will improve. Actually,Everyone knows that napping in summer is important, but the effect of napping is not based on people's feelings, but on how to sleep and how long they sleep.

The easiest time for people to fall asleep is 8 hours after waking up in the morning, or 8 hours before going to bed at night, around 1 p.m., when people's alertness is in a natural decline and the body will get a good rest. A healthy nap of 15 to 30 minutes is the most appropriate, and the maximum should not exceed 1 hour, the time is too short to meet the requirements of rest; If it takes too long, you will wake up with a slight headache and general weakness, and it is not easy to wake up at this time, so it is better to extend it to 1 1 5 hours for a complete sleep cycle.

In addition to paying attention to the time to fall asleep, you should also pay attention to hygiene during napping. Don't eat anything too greasy before going to bed, and don't eat too much, because greasy will increase blood viscosity, aggravate coronary artery disease, and oversatiety will increase the burden of stomach digestion. In addition, many people are accustomed to going to bed 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 and nutrition supply to the brain decreases significantly.

Therefore, it is best to move for about 10 minutes before napping, such as taking a walk, to facilitate food digestion.

These people don't get enough sleep at night, so after falling asleep at noon, they will be particularly listless.

Because we sometimes sleep for too long, the human body enters a deep sleep, so after waking up, the whole person will have no energy; It is best to control the nap to less than 10 minutes, so that it will be more comfortable.

That's because I didn't sleep until I woke up naturally, and if I woke up naturally, I wouldn't be listless.

This is because the time of napping is not grasped, the nap time should not be too long, nor too short, so that you can not achieve a good rest, the reason why you are listless after taking a nap may be because you have not rested well.

Sudden headache when you wake up from sleep may be too long asleep or it may be a lack of oxygen to the brain, it is recommended that you wake up and make yourself a cup of green tea or coffee Go out for a walk may alleviate these symptoms.

A healthy nap of 15 to 30 minutes is the most appropriate, if it is more than 30 minutes, the body will enter a deep sleep period that is not easy to wake up, it is better to extend it to 1 hour to complete a whole sleep cycle. If you take a nap for too long, you will have a slight headache and general weakness in the first half hour of waking up, which is caused by sleep inertia.
