What are the dangers of sleep deprivation?

The dangers of sleep deprivation:

1. Emotional instability. People with chronic fatigue are emotionally unstable because sleep and mood are regulated by the same brain chemical.

2. Aging before aging. Hormonal changes during sleep promote blood flow, so sleep well and be brighter and more resilient. Several studies have found that nighttime** renewals up to 8 times faster than daytime and is more effective at reducing wrinkles.

3. Resistance deteriorates. People who don't get enough sleep are more susceptible to diseases. In a foreign study, researchers injected healthy participants with a cold virus.

It was found that participants who slept less than 7 hours were three times more likely to be infected with cold viruses. People who slept only 4 hours a few nights in a row had a weaker immune response to the flu vaccine.

4. Slow response. Making tea also spills the tea on the new clothes you just bought. Such clumsiness may be the fault of lack of sleep.

Dr. Clay Kushda, director of the Center for Human Sleep Research at Stanford University, said there is a lot of evidence that people who are awake are slow, have trouble concentrating, have slow reactions, and have worse motor skills. In addition, drowsiness can lead to impaired balance and deep perception.

The dangers of poor sleep are:

It is easy to disorder the body's functions, and the first thing that is affected is attention, concentration, fine operation ability, high intellectual thinking and memory, learning efficiency and creative thinking ability will also be significantly reduced, followed by a decline in the resistance body.

People who are prone to anxiety and depression and are unable to get healthy sleep have a double and a double risk of having a good night's sleep. Long-term poor sleep can lead to autonomic nervous system dysfunction, nervousness and irritability, not getting along with people around you, depression, boredom and other emotions, and even pessimism and misanthropy. Therefore, the more severe the insomnia, the greater the risk of psychiatric symptoms.

Poor sleep can damage the stomach and liver. The reason why poor sleep will damage people's stomach and liver is related to people's digestive system, because staying up late and lack of sleep directly damage the two organs of people's stomach and liver, because it will increase the burden on the liver and destroy the digestive function of the stomach and intestines.

Cause or aggravate the occurrence of cardiovascular and cerebrovascular diseases: lack of sleep will lead to the heart has no way to get enough rest, and for a long time, it will lead to increased load on the heart and even sudden death. The incidence of hypertension, myocardial infarction, cerebral infarction and other diseases in the elderly with long-term insomnia is 25% higher than that of good sleep.

Accelerate aging and shorten lifespan: 10 p.m. to 2 a.m. is the most active time for cell necrosis and regeneration in the body. If you don't sleep well at night, the brain is prone to ischemia and hypoxia, which accelerates the death of brain cells, causes dysfunction of the cerebral cortex, causes autonomic nervous disorders, and leads to neurosis; It can also lead to a decrease in the ability to analyze and deal with problems, and a small number of people may even have some dementia symptoms; In addition, staying up late for a long time is prone to cancer.

It is prone to problems such as three highs and obesity. Sleep is very important, to develop healthy habits and lifestyle, early to bed and early to get up is not only good for beauty, but also for physical and mental health, prolonging life.

Occasional lack of sleep is generally not harmful to the body; However, if you don't get enough sleep for a long time, it may cause harm such as poor concentration, decreased immunity, and increased blood pressure.

1.Lack of concentration:

Staying up late for a long time can lead to long-term sleep deprivation, which may cause inattention during the day, which may be manifested as unresponsiveness, memory loss, etc., and may affect work or study efficiency.

2.Weakened immunity:

Staying up late for a long time can cause continuous lack of sleep, unable to ensure adequate rest, and may also cause a decrease in the body's immunity and prone to diseases such as upper respiratory tract infections.

3.Increased blood pressure:

If you stay up late for a long time, causing continuous sleep deprivation, it may cause disorders in the body's multiple nerve reflexes and regulatory mechanisms, resulting in an increase in blood pressure, which may endanger the body's health.

It is recommended to have a regular schedule and avoid staying up late to ensure adequate sleep. If there is a long-term lack of sleep and the body has uncomfortable symptoms, it is recommended to seek medical attention in time, clarify**, and standardize ** according to the doctor's instructions**.

This is an absolutely unhealthy way to sleep. The damage of long-term lack of sleep to the human body is mainly as follows: 1. It leads to neurasthenia, and the efficiency of work and study is greatly reduced; 2. If it is a teenager before the age of 18, it will also affect the growth and development, resulting in backward development; 3. Lack of sleep for a long time in women also affects endocrine function, leading to menstrual disorders, premature ovarian failure, and even affecting fertility, and men will also affect sexual function, resulting in impotence or **; 4. Long-term lack of sleep can induce cerebrovascular diseases; 5. Long-term lack of sleep can lead to a decrease in the body's immunity, and can even cause tumor diseases.

If you need to stay up late for some special reasons, you need to pay attention to the rhythm of sleep, such as people who need to work night shifts frequently, they need to take a proper rest before going to night shifts, and they also need to take proper rest after night shifts. At the same time, in order to avoid lack of concentration in the process of night shift, it is recommended that the sleep time is not too short during the non-night shift time, so that the impact of staying up late on the biological clock will be minimized.

Sleep is one of the most important physiological needs of the human body, and it is also one of the most basic repair and recovery mechanisms of the human body. During sleep, various physiological functions of the human body will enter a state of rest, so that the body can be fully rested and repaired. However, if you don't get enough sleep every day, it will cause great harm to your body.

Studies have shown that sleep deprivation can lead to a decline in physical performance, making the body prone to fatigue and sleepiness. Long-term lack of sleep can also lead to decreased immunity, susceptibility to diseases, and damage to cardiovascular and cerebrovascular organs. At the same time, lack of sleep can also have a negative impact on the physical mood and psychology, making people prone to negative emotions such as irritability, depression and anxiety.

So, does one or two hours of less sleep a day count as staying up late? According to the World Health Organization, adults should get 7-8 hours of sleep a day. If you sleep less than 7 hours a day, you can be considered sleep deprived.

And if you sleep less than 6 hours a day, it can be considered a severe sleep deprivation. Therefore, one or two hours of sleep per day can indeed be considered a state of sleep deprivation, and severe sleep deprivation is even more harmful to the body. Why are modern people prone to sleep deprivation?

On the one hand, the pace of life in modern society is faster than ever, and many people have to shorten their sleep time for the needs of work and life. On the other hand, many people rely too much on electronic devices such as mobile phones, TVs, and computers, resulting in a late time to go to bed at night and make it difficult to ensure adequate sleep time. In addition, some bad lifestyle habits, such as excessive alcohol consumption, smoking, and unhealthy diet, can also affect the quality of one's sleep.

In response to the problem of lack of sleep, we should take positive and effective measures. First of all, we need to pay more attention to sleep and ensure that we sleep no less than 7 hours a day. Secondly, we should reduce the amount of time we spend using electronic devices as much as possible, especially at night close to bedtime.

At the same time, establishing good lifestyle habits, such as regular diet, proper exercise, and avoiding excessive fatigue, can also help improve sleep quality and maintain a healthy physical state. In conclusion, one or two hours of sleep less per day can indeed be considered a state of sleep deprivation, and sleep deprivation can have a negative impact on a person's body and mind. Therefore, we should take active measures to ensure adequate sleep time and maintain a good living state to maintain a healthy and happy life.

Occasional lack of sleep will generally not cause harm to the body, but if you lack sleep for a long time, it may cause inattention, decreased immunity, increased blood pressure and other harms, staying up late for a long time can lead to long-term lack of sleep, may cause inattention during the day, may show sluggishness, memory loss, etc. may affect the efficiency of work and study, staying up late for a long time will also continue to lack of sleep, ensuring adequate rest may also cause the body's immunity to decline, prone to respiratory tract infections, It is recommended to have a regular rhythm of occasional lack of sleep, generally will not cause harm to the body, but if long-term sleep is insufficient, it may cause inattention, decreased immunity, increased blood pressure and other harms, staying up late for a long time can lead to long-term sleep deprivation, may cause daytime inattention, may show sluggish response, memory loss and other may affect work and study efficiency, staying up late for a long time will also continue to lack of sleep, ensuring adequate rest may also cause the body's immunity to decline, prone to respiratory tract infections, It is recommended to have a regular schedule, avoid staying up late, and ensure adequate sleep.

1. Frequent colds.

One of the dangers of sleep deprivation is a weakened immune system, which makes people more susceptible to various attacks, the most common being colds. One study found that people who slept less than 7 hours were 3 times more likely to suffer from cold poisoning than those who slept more than 8 hours a day.

2. Inexplicably sad.

When we don't get enough sleep, we may be more likely to feel sad and depressed because a tired brain is more likely to store negative emotions. In addition, people who lack sleep are always emotionally unstable, for example, people who lack sleep are more likely to be scared and anxious.

3. Clumsy.

Studies have found that people who lack sleep have imprecise motor skills and slow movements, which is one of the more common hazards of sleep deprivation.

4. Increase in waist circumference.

Long-term lack of sleep can cause confusion in blood sugar levels, causing the body to produce more leptin, a hormone that causes appetite. As a result of these physiological shifts, people who lack sleep are more likely to binge eat. Therefore, one of the harms of sleep deprivation is that it leads to an increase in waist circumference and weight gain.

5. Hesitation.

Sleep-deprived and tired people are always unable to distinguish between important and irrelevant information, resulting in the simplest decisions being exaggerated. In addition, people who are sleep deprived often take risks to maximize their chances. Then, the risk of uncertainty will also increase.

Long-term sleep deprivation can cause harm to physical health in many ways, including but not limited to the following:

Cognitive decline: Lack of sleep can affect the cognitive functions of the brain, including concentration, memory, learning ability, etc., making people more likely to be distracted and make mistakes.

Impaired immune system: Lack of sleep can affect the normal function of the immune system, reduce resistance, and easily cause colds, flu and other diseases.

Emotional instability: Lack of adequate sleep can lead to mood swings and a tendency to mental health problems such as irritability, irritability, and depression.

Affects metabolism and weight: Lack of sleep can affect metabolic processes in the body, making appetite and eating habits irregular, which can easily lead to weight gain.

Cardiovascular health problems: Chronic sleep deprivation is associated with an increased incidence of cardiovascular diseases such as high blood pressure and heart disease.

Affects muscle recovery and repair: Sleep is an important period for muscle recovery and repair, and lack of adequate sleep can affect the body's ability to do so.

Affects photosynthesis: Lack of sleep can reduce the body's absorption of sunlight and affect vitamin D synthesis, which in turn affects calcium absorption and bone health.

Affect reproductive health: Sleep deprivation may affect the normal functioning of the reproductive system and affect fertility.

Reduced work and driving safety: Lack of adequate sleep can reduce productivity and increase the risk of accidents while driving.

Accelerates the aging process: Long-term sleep deprivation may accelerate cellular aging and affect the overall health of the body.

Therefore, getting enough sleep is an important part of maintaining good health. Adults typically need 7 to 9 hours of sleep per night, and specific needs vary from individual to individual. If you feel persistent fatigue, difficulty concentrating, emotional instability, etc., it may be caused by lack of sleep, and it is recommended to adjust your routine and rest to ensure adequate rest.

If the problem is severe or persistent, it is advisable to seek the advice of a medical professional.

1. Temper tantrum: When people are focused on doing something, if they are interrupted due to unexpected interference, negative emotions will be generated; If you don't get enough sleep, this negative emotion will be amplified.

2. Headache: Scientists still can't find out the reason behind it, but 36 58% of people who don't get enough sleep will have headaches when they wake up.

3. Reduced learning ability: short-term memory is an important key to determining learning effectiveness, and people who lack sleep will have weakened short-term memory ability, which also affects the learning effect.

4. Weight gain: People who lack sleep will have hormonal imbalances in their bodies, not only will their appetite increase, but they will also want to eat high-calorie foods more, and their ability to control impulsive behaviors will also decrease, and these factors add up to lead to rapid weight gain.

The University of Cleveland Medical Center evaluated the skin condition of 60 women between the ages of 30 and 49 and confirmed that a good night's sleep leads to a fresher and more energetic feel, and a lack of sleep accelerates aging.

Half of the women in the study, who defined sleep deprivation as less than 7 hours a day as sleep deprivation, or poor sleep quality, were more likely to have fine lines, uneven skin tone and loss of elasticity than those who slept enough. At the same time, they themselves have a poor evaluation of ** and facial appearance.

As part of the study, the researchers also found that in addition to increased signs of aging, sleep-deprived people also experienced slower self-healing after suffering from external injuries, such as barrier disruption or UV exposure. For example, the same sunburn, people who don't get enough sleep may still be red and inflamed after 72 hours of sunburn, while people who get enough sleep** recover well.

Frequent diarrhea, colds, heat stroke Young people lack sleep and are in poor health.

The Chinese Sleep Research Association recently released the "2017 China Youth Sleep Status Report", and "sleeping well" has become a luxury for young people. The survey included people between the ages of 10 and 45 and surveyed nearly 60,000 people. In terms of overall sleep status, 76% of respondents said it was difficult to fall asleep, more than 13% of them even felt in a state of pain, and only 24% said that their overall sleep was good.

Among them, those who can "sleep until dawn" can be called God's favorite, while only 11% of young people who are "heartless" are so "heartless", and the rest of the respondents said that they will wake up in the middle of the night.

93% of respondents consume a lot of sleep time by playing with their mobile phones, watching TV shows and shopping before going to bed. The survey shows that some people who usually pay attention to beauty reading content still maintain a very active state on their mobile phones at 2 o'clock in the morning, which can be described as "sticking to the ** screen".
