Possible physical  Side effects  of Sleep Deprivation

    A good night's sleep does not please anyone, it not only makes your mood pleasant but also prevents the formation of ugly dark circles around the eyes, but sleeping for a reasonable period of time will improve the health of everything including your heart, weight, and mind. Proves to be the best.

But today's busy schedule has brought the average duration of sleep to 6 hours (medical experts recommend 7 to 8 hours ).

Almost everyone knows the importance of a good night's sleep, but you may have no idea what can happen to you if you don't.

Here some physical side effects of sleep deprivation.


Irritability and emotional complaints are common as a result of sleepless nights. This was revealed in a medical study that showed that negative emotions are the result of sleep deprivation and also affect office performance and driving ability as well.


Scientists aren't sure why sleep deprivation causes headaches, but it does. Sleepless nights cause half of the headaches, while 36 to 58% of people who snore have headaches in the morning.


Sleep deprivation can lead to hormonal imbalances, which can lead to cravings for food, especially high-calorie foods. The ability to control one's desires is lost and the two are a very dangerous combination as it results in obesity while feeling tired all the time.

Visual impairment

Sleep deprivation can also be manifested in the form of visual impairment, blurred vision and double vision instead of one. The more time you spend waking up, the more likely you are to have a visual impairment, and the more likely you are to experience hallucinations.

Heart disease

One study found that people were not allowed to sleep for 88 hours, which led to high blood pressure, which was not surprising, but when they were allowed to sleep for only 4 hours each night, their heart rate increased. As the body began to store proteins that increase the risk of heart disease.

Slow response

When it is not complete, the reaction to any event slows down. In one study, people were given the task of making quick decisions, some of which were allowed to sleep during the test, while others were not. Those who got a chance to sleep performed better in the test while others performed worse and the response was very slow.


Do you know how to strengthen the body's immune system, especially without an open wound? That is sleep. If you suffer from sleep deprivation, even a lack of sleep at night can have a negative effect on the body's natural defenses against germs.

Impaired attention span

Having difficulty concentrating while reading or listening? Struggling to do something that requires more focus? Focusing tasks are most affected by sleep deprivation. According to a study, if you want to be mentally alert and alert, you should get enough sleep, otherwise, the mind becomes drowsy and it becomes very difficult to do anything.

Decreased effect of vaccination

Vaccines usually produce antibodies in the body that can protect against a specific virus, but when you do not get enough sleep, your body's immune system weakens and these antibodies do not work effectively.

Get angry quickly

Another study found that Sleep deprivation affects the emotional centers of the brain in such a way that they become 60% more active. Simply put, these centers prevent you from processing your emotions and reacting appropriately to the situation.

Difficulty speaking

Severe sleep deprivation can make you stutter or have difficulty speaking, just as if someone were addicted. During one study, volunteers were kept awake for 36 hours, after which they repeated and stammered words while talking to someone. They began to speak slowly and vaguely in a tiring manner, even sharing their thoughts with them. It has not been possible to express.

Chronic colds

If you are always worried about catching a cold and the flu strikes wherever you go, one possible reason may be insufficient sleep. According to a study, people who get less than 7 hours of sleep are three times more likely to get the disease.

Stomach diseases

Inflammatory diseases of the stomach get worse as a result of lack of sleep. Seven to eight hours of sleep provides adequate protection against stomach ailments, but a decrease in it increases the risk.


During sleep, our body eliminates metabolic disorders, but waking up more often increases the risk of insulin sensitivity, which can lead to type 2 diabetes. One study found that an increase in sleep duration may reduce the risk of diabetes, while another study identified a link between a normal sleep pattern and a risk of diabetes.


Medical experts have studied the link between sleep and cancer and found that the body's clock system intervention weakens the body's immune system and increases the risk of certain types of cancer, especially breast and colon cancer.

Memory problems

Lack of sleep in middle age causes changes in brain structure that have a negative effect on long-term memory, while sleep deprivation can also be seen in young people. According to a study, people who sleep more have a better memory.


According to a study, deprivation of adequate sleep reduces the risk of infertility, especially if women are accustomed to less than 7 hours, which has a negative effect on their ability to conceive. Research has shown that sleep affects the body's hormonal system, and too little sleep affects the female hormonal system, which increases the risk of infertility. In another study, men found that sleep deprivation can increase the risk of miscarriage accident, especially with less than six hours of sleep.

Feeling hungry all the time

If the brain does not get the energy it needs from sleep, it uses food as a source of energy. Fat and sweet foods are common all the time, lack of sleep also affects the hormone leptin, which controls appetite, and people eat too much unnecessarily and do not feel full.

Loss of control over intent

When the body and mind are tired, people take thoughtless steps, that is, it becomes difficult for people to deny something harmful, while they also start spending money on unnecessary purchases, usually in situations where people are saying or doing, they themselves do not understand.

Premature aging

Sleep is very important for facial beauty and it is common to get dark circles around the eyes and face without sleep, but a study also found that too much sleep deprivation can cause your skin to age faster. This is due to the release of excessive amounts of the stress hormone cortisol in the body and its excess does not allow the collagen, the protein that keeps the skin smooth and smooth.

Feeling lonely

One study found that sleep deprivation makes it harder for young people to socialize with people and makes them feel isolated from the world. Things get worse when people who feel lonely don't try to get enough sleep.

Alzheimer's disease

Numerous medical research reports have found that sleep helps cleanse the brain of beta-amyloid proteins that accumulate in the brain when you wake up more. These proteins are thought to cause Alzheimer's disease. The more you sleep, the harder it is to clean. The worse the sleep schedule, the greater the risk of Alzheimer's disease.

The risk of depression increases

One study found that poor sleep not only makes people more irritable, but also increases their risk of depression. Lack of sleep also increases the likelihood of escalating fights between husband and wife, which in turn can ruin their relationship. According to researchers, people with insomnia are twice as likely to develop depression.

Weak muscles

Lack of sleep changes the hormonal system and makes it harder for the body to build muscle and eliminate weakness, which is why it becomes more difficult to treat after damage to the muscles. The study found that sleep increases the body's release of growth and repair hormones, which is why fitness experts recommend adequate sleep for bodybuilders.

Lack of or excessive sleep can be fatal

This was revealed in a medical study in South Korea.

Research from the Seoul National University College of Medicine has shown that too little or too much sleep is bad for your health. The study looked at the sleep times of more than 133,000 men and women and looked at how sleep duration affects health.

The results showed that people who are accustomed to sleeping for 6 hours or less are more likely to develop metabolic syndromes such as high blood sugar, high cholesterol, high blood pressure, and fat around the waist than those who sleep for 8 hours. The risk of stroke is very high, as well as the possibility of a rash.

But people who sleep for 10 hours or more are not good for their health because they also have an increased risk of metabolic syndrome, especially in women.

According to researchers, these findings are currently analytical and it is difficult to say for sure how long sleep causes medical problems.

But it does reinforce past evidence that sleep and health are inextricably linked.
Another recent study found that people who slept for 5 hours or less had a higher risk of dying from any cause than those who slept for 7 to 8 hours.

However, if such people try to make up for the lack of sleep during the holidays, the risk of dying from serious illnesses can be significantly reduced.

Research has shown that there is no substitute for regular sleep, but it depends on people's body clock, meaning that different people experience drowsiness at different times of the day.

The South Korean study did not determine the ideal sleep times.

The results of the study were published in the medical journal BMC Public Health.
