It s good to take a nap, but why do you sometimes wake up physically and mentally exhausted and feel

Nowadays, many office workers have the habit of taking a nap, and they can take a beautiful nap at noon, which is of great help to the efficiency of the afternoon, but some people always feel physically and mentally exhausted after the lunch break, not only feel very tired, but also always feel that they have not woken up, making the whole afternoon work listless.

Generally speaking, a half-hour nap is good, not too long. This is because people usually fall asleep half an hour after falling asleep. At this time, it is in the stage of central nervous system inhibition, the blood passing through the brain tissue is relatively reduced, and the human muscles are in a relaxed state, and the metabolic processes in the body are relatively reduced.

If you wake up at this time, the inhibition of people's cerebral cortex has not been lifted, and they are prone to symptoms of general discomfort, dizziness, and exhaustion. Therefore, the nap time should not be too long, preferably around 30-40 minutes, that is, it has not yet entered the period of deep sleep. By now you should know why you get more and more tired as you sleep.

In addition to the influence of timing, there are other factors that can also affect the quality of sleep.

1: Sleep when you're full. Many office workers have a fast pace, and they basically sleep at the time of pinching, so many people will be ready to sleep immediately after eating, although people are indeed easy to get sleepy after eating a full meal, and they can quickly enter the sleep state, but falling asleep immediately after a full meal will affect the peristalsis of the stomach and is not conducive to the digestion and absorption of food.

Sleeping while the stomach is still working, it will also affect the quality of sleep.

2: Nap position. When taking a nap, you must let yourself have a comfortable sleeping position, many people like to sleep on their stomachs, which will lead to problems with the cervical spine, and will also lead to insufficient blood supply to the hands, and numbness in the hands.

Generally speaking, lunch break is indeed good for the body, but don't sleep too comfortably, too comfortable is easy to enter deep sleep, easy to cause fatigue of the body, and don't sleep for too long, easy to affect the quality of sleep at night.

The main reason is that the nap time is too long, and the body cannot recover quickly after waking up, so there will be a feeling of exertion.

There is no need to rest for too long, otherwise it will cause physical discomfort.

It's because you've slept for too long. As a result, the body cannot adapt. So I think it's best to keep your nap time to less than half an hour.

Take a nap and talk about some "skills".

Busy work and tense rhythm often make manpower inadequate, so napping has become an important guarantee for many people's work in a day. Experts believe that napping can not only enhance physical strength, eliminate fatigue, improve work efficiency in the afternoon, but also have the effect of enhancing the body's protective function. However, there are many things to pay attention to in napping, and only a reasonable napping method can achieve the best effect.

First, don't rush to take a nap after eating. 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 supply and nutrition to the brain drop significantly. Therefore, it is best to move for 10 minutes before napping to allow food to digest.

The second is to pay attention to the time to fall asleep. Most people think that as long as you sleep at noon, you can achieve the effect. However, according to experts, 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 o'clock in the afternoon.

Because at this time, people's alertness is in a natural decline period, and the body will get a good rest during the nap at this time.

The third is to pay attention to hygiene during naps. 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, after waking up, you can drink a glass of water to replenish blood volume, dilute blood viscosity, and then you can do some light activities such as walking.

Fourth, napping should not be too long. Experts believe that a healthy nap is most appropriate for 15-30 minutes, and the longest should not exceed 1 hour. If the time is too short to achieve the effect of rest; If it takes too long, you will wake up with a slight headache and general weakness, and it will not be easy to wake up.

Fifth, don't sleep on your stomach during a nap. It is understood that most people do not pay attention to the posture of napping, some lie on their stomachs, and some simply sleep on the table. In fact, sleeping at the desk will reduce the blood supply to the head, and people will 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 pillows will compress your eyeballs, which will easily induce eye diseases over time, and lying on the table will compress your chest, affecting blood circulation and nerve conduction.

Because your brain and body are tired before you go to bed, once you relax, if you don't rest enough, you will feel more normal, so it is recommended to pay more attention to rest.

Two reasons.

1 The first is the lack of oxygen, and the lack of air circulation when sleeping is the wrong sleeping position, such as sleeping on your stomach.

I also often get tired after napping, and sometimes I have headaches.

A proper nap can go a long way in improving the spirit of work life in the afternoon and evening.

However, if you take a nap for too long, it will lead to lack of energy in the afternoon, so it is recommended that the nap time be one hour.

I don't know if you will feel dizzy after your lunch break, and you feel that it is better to not sleep.
