Why can excessive drowsiness appear, what threatens too much sleep, and in general - how much is it?

The night is over, the day is coming, a pleasant melody wakes you up ... However, something went wrong. Instead of feeling energized and rested, you barely open your heavy eyelids and feel drained of energy and clumsy. Immediately after returning home, you go to improve your condition - to sleep. It is a pity that the effect is not very impressive ... Why can't you sleep a lot? What happens if you spend too much time in the arms of Morpheus?

Why you want to sleep a lot: causes of excessive sleepiness

A lot of sleep is harmful, but sometimes you really want it! But it is one thing when it comes to periodically relieving fatigue and stress, and quite another when a person spends more time in a dream than it should be according to generally accepted standards. Why?

Excessive sleepiness is sometimes associated with specific conditions such as hypersomnia or sleep apnea, and is also a symptom of thyroid problems or diabetes.
An increased need for sleep occurs in people who are very active physically, often tired.
Many people want to sleep a lot in autumn and winter, when there is simply not enough light.
Sometimes increased drowsiness occurs in the process of taking certain medications.
A "drunk" party may continue in the form of an increased desire to sleep.
Finally, there are people who simply love to sleep in principle.

Why is too much sleep bad for health? What happens if you sleep more than normal?

We need to get enough sleep, but scientists warn us against becoming too attached to our comfortable beds and sofas. Their arguments are quite amazing! What is the danger of too much sleep?

1. Diabetes

Studies have shown that, oddly enough, it provokes both too little and too much sleep.

2. Obesity

Observations of scientists confirm that people who sleep 9-10 hours a day are 21% more at risk of obesity over 6 years than those who sleep 7-8 hours. But pay attention: lack of sleep causes the same consequences!

3. Headache

This problem often appears in people prone to it, especially on weekends and holidays, when there is an opportunity to sleep longer. The same thing happens in people who sleep during the day, which disturbs their sleep at night. Therefore, they suffer from morning headaches.

4. Pain in the spine

It is harmful to health to sleep a lot also because the spine can suffer. The times when passive lying was a means of combating such diseases is fading into oblivion. Now doctors recommend daily physical activity, which brings much more relief.

5. Depression

Insomnia is usually associated with this condition (and rightly so). But about 15% of depressed people sleep too much, which experts say can worsen their condition. Why? Because habits associated with regular sleep help fight the disorder.

6. Heart disease

Studies involving 72,000 women showed that those who slept 9-11 hours a day were 38% more prone to heart disease than women who slept 8 hours a day. Doctors are still investigating what is the secret of this addiction.

7. Shorter life

This is true in a figurative sense, as we spend more time detached from reality. But people live less and in the most direct sense. It remains to be seen what this correlation is based on, but the researchers argue that people with depression or with lower social status (which may be related) generally sleep more.

How many hours of sleep does a person need?

The list of diseases and problems is quite long, right? So it's better to get enough sleep, but within reason. What is our need for sleep? Doctors recommend spending 7-8 hours a day in the arms of Morpheus. The hygiene of this process is also important. If you go to bed and wake up at the same time, avoid late drinking of alcohol and caffeine, sleep on a comfortable mattress in a ventilated bedroom, sleep will become a time of real rest and recovery for you, because this is its main mission.

Is it worth it to get enough sleep "in reserve" when the opportunity arises? If you periodically think about this question, then remember that it is harmful to sleep a lot. The consequences of this can be almost sadder than lack of sleep, the negative effect of which is so much talked about today.

We often hear that it is necessary to get enough sleep, then there will be no health problems. This is true, you need to devote time to sleep, but sleeping more than you need is no less harmful than less.

It is necessary to figure out how much time a person needs for a good sleep in order to feel alert and rested. You can’t be in the arms of Morpheus for too long, it won’t bring any rest for the body. But problems can arise quite serious. But why is it so harmful to oversleep and what is it fraught with, and in general - is it harmful to sleep a lot or is it just a myth?

Sometimes you really want to sleep, although doing this in large quantities is harmful. But why is the violation of generally accepted norms so dangerous, what's the matter here?

Often it is associated with certain medical conditions such as hypersomnia. This means that a person has problems with the thyroid gland or develops diabetes;
Physically active people often need long rest periods;
Especially often such a desire arises in the winter and autumn periods, the body simply does not have enough light;
Taking certain medications often leads to increased drowsiness;
A strong desire to sleep more than necessary is often caused by the consequences of a fun party that took place the day before.
And do not forget about those people who just love to spend a lot of time in bed and there are a large number of them all over the world. But they need to know why it is harmful to sleep for a long time and what such a habit can lead to.

Why is it harmful to human health

Nobody argues with the fact that it is necessary to get enough sleep, it is useful and necessary for a person, but it is harmful to sleep a lot. A strong attachment to a cozy bed does not lead to anything good. And here is what this habit is fraught with:

Sleep disturbance often leads to the development of diabetes. And it doesn't matter if a person sleeps less than necessary or more.
In the course of scientific observations, it was found that people who sleep more than 10 hours a day are 5 times more likely to suffer from obesity than those who sleep at 8 hours. You should not sleep more than you should, more than 8 hours is already superfluous.
Such people often have a headache, especially when it comes to holidays and weekends. It is no secret that if there is an opportunity not to get out of bed for a long time, many people use this opportunity. The situation is observed in those people who prefer to sleep during the day, at night the process is already disrupted. And in the mornings my head hurts, and all because there is such a bad habit.
The human spine suffers. Many people think that passive lying is good for the spine, but this is not true. In such a situation, only physical activity will help, which brings positive results after a short time and sleep becomes better.
Oddly enough, but often such people suffer from depression. It overtakes those who suffer from insomnia and those who sleep too long. They often say that I sleep a lot and still get tired quickly, but there is nothing strange in this.
People who sleep more than 10 hours a day are 3 times more likely to develop heart disease. But the secret of such dependence has not yet been fully clarified, there are many reasons, but the fact that it is dangerous is unequivocal.
Such people live much less, it has been proven that people who suffer from depression or those who have a low social status devote a significant amount of time to sleep. A person often sleeps a lot because he has nothing to do, and a successful person falls asleep as needed.

How much sleep does a person need

Sleep is necessary, but it should be in reasonable quantities. What is a reasonable amount? Doctors say that it is enough to spend no more than 8 hours a day in the arms of Morpheus, so that it is regular, do not drink alcohol and caffeine late, sleep in a well-ventilated room so that the mattress is comfortable. Then everything will become normal, everything is ready for recovery and relaxation, as it should be, this is precisely the main mission of a night's rest for a person.

And do not try to get enough sleep in advance, when there is such an opportunity. Nothing good will come from such a rest of the body. Adults need to fully relax, but do not abuse it, long sleep, unlike normal sleep, does not lead to anything good.

How extra hours in bed affect a person's memory

People who spend more time at night than necessary often suffer from high blood pressure. Their risk of developing diabetes also increases significantly. Blood to the brain interrupts in insufficient quantities, it works inefficiently. He lacks glucose and oxygen.

Memory becomes worse, concentration of attention is significantly reduced, and the risk of dementia increases. You should not try to take a nap longer, if a person has slept more than eight hours, he has not rested. Long-sleeping people often give out a tired look and puffiness.

The bed is only for sleeping and having sex. Reading, watching TV and eating in bed is not necessary.
If you can’t fall asleep in 20 minutes, you need to get up and take a little walk around the house. Read, but also watch TV or work at the computer, it only excites the body. As soon as you feel sleepy, you have to go back to bed. And don't set your alarm clock ahead.
You need to go in for sports, at least half an hour a day to devote physical activity. In the morning it is necessary to do exercises, before falling asleep to do yoga, then the mind and body will be relaxed.
If possible, complex tasks should be completed in the morning. Then, when going to bed, a person feels calm and confident.
Don't go to bed on an empty stomach. Well, you shouldn't eat right before that. Eat a salad or an apple just right.
Caffeinated drinks should not be drunk 2 hours before bedtime.
Do not drink a lot of liquid at night.
do not drink alcoholic beverages. This does not relax, as some people think, but the quality of sleep deteriorates significantly.
The room should be quiet and dark, a sleep mask and earplugs help a lot.
Before going to sleep, you need to breathe properly, slowly inhale deeply and exhale quickly.
It is useful to take a nap during the day, but it is important not to overdo it.

However, the reasons for this phenomenon have not yet been established, because many factors affect conception.

But lovers of the kingdom of Morpheus are interested in the question - is it harmful to sleep a lot? Too much sleep, it turns out, also has a bad effect on health. Prolonged sleep can provoke diabetes, heart disease and reduce a person's life expectancy.

Every person has their own sleep schedule. It depends on age, health status, activity level and frequency of stress in life. On average, it is normal for people to sleep for 8-9 hours. Exceeding the norm for several hours is a pathology called "hypersomnia".

People suffering from pathological drowsiness constantly walk sluggish, sleepy, get tired quickly, although they show low activity during the day. Of course, not always a long sleep is a consequence of "hypersomnia". Factors such as depression, alcohol intoxication, and taking certain medications can affect the amount of sleep you get.

Scientists who conducted research on the effect of long sleep on the condition and health of people found that if a person sleeps 10-12 hours every night, he can get coronary heart disease, obesity, diabetes, and also shorten his life much. Sleep-deprived people who have enough 5-6 hours of sleep live much longer than their one-year-old dormouse. That is why it is harmful to sleep a lot.

It is especially harmful for women to sleep a lot. Regular excess of sleep even by 1 hour leads to a 1.5-fold increase in the risk of developing cardiovascular diseases in women. In addition, oversleeping makes a woman irritable, distracted during the day, leads to frequent mood swings and, ultimately, to stress.

However, according to the latest research by scientists, in this way he not only does not restore energy, but also harms his health.

Why is it bad to sleep a lot?

So, according to numerous studies, excessive sleep can lead to a decrease in socio-economic status, as well as provoke mental and physiological disorders in the body. In particular, American researchers from Yale University, who have been studying the relationship between sleep duration and the risk of various diseases for 15 years, found that people who sleep more than 9 hours a day 50% higher risk of developing diabetes than those who sleep 7 hours.

Sleep a lot - get enough sleep for yourself

Scientists came to these conclusions thanks to a study in which a thousand male volunteers who do not have diabetes were divided into three groups: group 1 - participants who did not get enough sleep (sleep less than 6 hours a day); group 2 - participants who slept 7-8 hours a day; Group 3 - people who spent more than 8 hours sleeping. As a result, it turned out that the incidence of diabetes mellitus among members of the third group is three times higher than cases of this disease among the participants of the first two groups. At the same time, this pattern took place regardless of other factors of the disease, such as weight, age, and smoking habit.

Sleeping too long can lead to diabetes

In addition, a group of scientists from the University at Buffalo found that Sleeping more than eight hours a night significantly increases the risk of stroke. Team leader Ednan Kvareshi, assistant professor of neurosurgery, notes that “if you sleep less, but feel quite alert and productive during the day, everything is fine. But if you are overcome by daytime sleepiness, it’s bad. You are also at risk for stroke, if you snore in your sleep.

In this study, scientists took part in 1348 people, including those who had this disease. All subjects underwent a thorough medical examination, the purpose of which was to identify possible disorders in the cardiovascular system. Doctors paid special attention to the habits and features of the sleep of the subjects, as well as to the narrowing in the body of the coronary artery. The results showed that 14% of those surveyed from the group sleeping more than eight hours a day experiencing daytime sleepiness and snorers, have had a previous stroke or ischemic attack, which is similar to small, since it affects the vessels of the brain or the vessels leading to it. On the contrary, among those who did not suffer from such sleep disorders, there were only 4-5% of stroke survivors.

Team leader Ednan Kvareshi believes that people experiencing such sleep problems should definitely see a doctor. The scientist notes that these may be signs of stopping breathing during sleep (apnea), which leads to the fact that the brain is left without oxygen for a short time, resulting in an increased risk of stroke. “This can happen many times a night, sometimes a person wakes up. Most often this happens in a chronic snorer. Meanwhile, people who experience sleep apnea do not get enough sleep and need to sleep longer, otherwise they “nod” during the day, ”concludes the researcher.

In turn, researchers from West Virginia University found that too long is directly related to the risk of cardiovascular disease. sleep in women. According to the results of their research, if a woman sleeps 9 or more hours a day, then the risk of heart problems increases by 1.5 times.

Long and prolonged sleep increases the risk of stroke

All scientists believe that sleep disorders increase the risk of stroke within 10 years after their occurrence. “How much and how a person sleeps,” says Dr. Kvareshi, “is not just a habit that is easy to change. Sleep disorders are physiological disorders that require the intervention of specialists.”

According to medical research, excessive sleep - more than 8 hours a day - can also cause headaches, which can also affect people who sleep a lot during the day and little at night. In addition, the habit of long sleep can lead to excessive weight gain. According to scientists, people who sleep 9-10 (11.12) hours a day are more prone to obesity in the next 6 years than those who sleep 7-8 hours. Recent studies by scientists also show that among lovers of long sleep - 15%, suffering from depression.

Thus, long-term studies of scientists have made it possible to determine what serious violations can occur if a person sleeps for a long time. So, it was found that who sleeps from ten to twelve hours every night, can acquire diseases such as diabetes, obesity, depression, as well as increase the risk of stroke and heart problems. In addition, according to scientists, long sleep shortens life. Researchers have found that those who get only five hours of sleep live much longer than people who are used to sleeping ten to twelve hours.

Scientists are sure that to maintain energy, a middle-aged person should sleep 7 hours a day and in no case more than 9. Therefore, for those who sleep more than seven or eight hours, doctors recommend undergoing a medical examination and determining the cause of oversleeping.

You should also try to adhere to the correct daily routine and follow a few simple rules for a good rest. So, doctors do not recommend taking alcohol and caffeine for several hours before bedtime. You should also make sure that the bedroom and bed are comfortable. Doctors advise airing the sleeping room thirty to forty minutes before bedtime every day. Before going to bed, you can read an interesting book, listen to pleasant, soothing music. Regular exercise doesn't hurt either.
