What happens when you sleep for a long time, and what problems can sleep for a long time cause?

It depends on your own physical condition and what the reason is.

If you don't exercise, it's definitely not good for your health, it's hard to say whether you will gain weight, and some people can grow meat when they drink water.

Ordinary people generally sleep for about 8 hours a day, and those who are frail and sick should increase their sleep time appropriately.

Human sleep is rhythmic, alternating deep sleep and light sleep until you wake up. The first half of sleep is mostly deep sleep, and the second half is mostly light sleep. In the case of a person sleeping for a long time, deep sleep does not increase, but only prolongs the time of light sleep.

People who can fall into deep sleep soon, even if the light sleep time is relatively small, will not affect the mental state; On the contrary, it only prolongs the light sleep time, but the sleep quality does not improve, and you still feel "unsatisfactory" after waking up.

Sleeping too long is not good for health, sometimes 9 hours of sleep is greater than 6 hours of sleep, longer and shorter sleep time will increase the risk of diabetes, coronary heart disease, and even death, while 7 hours of sleep has the lowest risk of diabetes, the lowest risk of coronary heart disease and the lowest risk of death.

Sleeping too long not only can't eliminate fatigue, but also brings a lot of harm to the human body.

1.Weakness. When a person is active, the heart beats faster, the contractility of the heart muscle increases, and the cardiac output increases.

When the human body is resting, the heart is at rest, and the heartbeat, contractility, and blood output decrease. If you sleep for a long time, it will destroy the rhythm of rest and exercise of the heart, and the heart will rest again and again, and eventually the heart will be weakened by contraction, and the heart will not beat after a little activity.

1. Panic and fatigue, so I have to lie down again to form a vicious circle, resulting in weakness.

2.Susceptibility to respiratory diseases. The air in the bedroom is the dirtiest in the morning, even if the windows are closed, there is still some air not circulated, and the unclean air contains a lot of bacteria, viruses, carbon dioxide and dust, which has an impact on the respiratory tract's ability to resist diseases.

As a result, those who snooze behind closed doors often suffer from colds, coughs, and sore throats.

3.Limb fatigue and weakness. After a night's rest, muscles and joints will become relaxed, and immediate activity after waking up can increase muscle tension, increase the blood of muscles, make bones and muscle tissue in a state of repair, and eliminate metabolites accumulated in muscles at night, which is conducive to muscle tissue recovery and exercise.

People who sleep lazily miss the opportunity to move due to muscle tissue, and feel weak legs, lumbosacral discomfort, and weakness after waking up.

4.Affects digestive function. Lazy people cannot eat on time, and the gastrointestinal tract has hungry peristalsis, which disrupts the secretion of gastric juice and affects digestive function.

5.Interferes with nervous system function. People who sleep lazy sleep have a long-term excited sleep center, while other nerve centers will be relatively slow to resume their functions due to inhibition for too long, so they will feel groggy and listless.

The landlord is likely to be a problem with sleep habits, insist on getting up at 7 o'clock in the morning for 2 weeks, go out for a walk, find something to do, I think your biological clock will be adjusted.

Not sleeping for a long time can lead to a decline in the patient's physical function, and in severe cases, sudden death. Patients with lack of sleep will manifest themselves in a short period of time with dizziness, heaviness, difficulty concentrating, fatigue, palpitation and other manifestations.

1. Easy fatigue and poor mental state.

Many people think that sleep is when we rest, the longer the sleep time, the better the mental state of the body, in fact, it is not, when we sleep, the speed of the body's metabolism slows down, and the speed of blood circulation will also slow down, which will cause the body's nutrients and oxygen to dredge to all parts of the body, and the brain is prone to the problem of hypoxia after a long period of sleep, which leads to poor memory.

2. Affects heart function.

When people are resting, the various organs of the body are also resting, and our heart is the same, sleeping for a long time, it will cause the contraction rate of the heart, simply put, our heart's working ability decreases, and when we encounter a little need for exercise, it is easy to have problems such as palpitation and shortness of breath, and the body will become weak, the resistance will decline, and it will be easy to be attacked by germs, so we must arrange our sleep time in total, and do not sleep for a long time.

3. Cause weight gain.

What is sleep, is the human body in a dormant state, the whole body with speed, the decomposition of food in the body will slow down, sleep we do not need the following body calories, the food eaten is not consumed, it will become fat storage, so often long sleep will cause body weight gain, become obese, and obesity will also cause coronary heart disease, diabetes, hypertension and other diseases.

4. Cardiovascular disease.

We sleep for a long time is not good, sleep time is too short, will cause cardiovascular disease, because during sleep, our blood circulation slows down, blood will be deposited on the blood vessel wall, for a long time it is easy to cause thrombosis or arteriosclerosis and other problems, so we usually have to arrange sleep time reasonably, 6 8 hours of sleep time is the best, the baby's time can be 1 2 hours longer, and the elderly time is generally 6 hours.

The first type of sleep in a normal human body is six to eight hours. Sleeping too long will cause some damage to the stomach and intestines, so it will lead to gastritis or stomach ulcers. Second, it will affect heart function, and sleeping too long will disrupt the regularity of heart movement, resulting in irregular heart rate and palpitation.

Third, it will lead to insufficient oxygen supply to the brain, resulting in headaches, dizziness, nausea, vomiting, sluggish thinking, slow reaction and other symptoms.

Sleeping for a long time will make the whole body very tired, and then it will be easy to get tired, and it will slow down the speed of our blood circulation, so that the metabolism will also slow down, may get old, and will also hurt our stomach, hurt our brain, and will get some cardiovascular and cerebrovascular diseases, and will lead to weight gain.

It will become more sleepy the more you sleep, affect the body's metabolism, insufficient blood supply to the brain, limited thinking, poor blood circulation, and affect our heart function, because the lack of exercise will affect the contractility of the heart.

It will make your brain lack oxygen, your brain's ability to react slowly, your memory will not be very good, your blood circulation will not be good, and your body will have some diseases.
