Here are 10 harms to your body and brain caused by lack of sleep
Lack of sleep is associated with a higher risk of certain cancers.
We are advised by doctors to sleep 7-9 hours a night. But many people say that because of work or family, they cannot. A typical and famous case is CEO of Tesla and SpaceX, Elon Musk. With a 120-hour-a-week schedule and just six hours of sleep a day, Musk recently had to burst into tears in an interview with the New York Times, acknowledging that his health was going down. Because of this, Arianna Huffington, the founder of The Huffington Post, had to send an open letter to Musk about his sleep schedule. Arianna advised that Musk is “using human energy in an extremely outdated, anti-scientific and extremely inefficient” way.
Matthew Walker, a neurologist and sleep expert, once said, “The shorter your sleep time, the shorter your life will be.” Most adults need 7-9 hours of sleep each night, children need more sleep. Rarely, some people may actually need only a few hours of sleep each night, while others need 11 hours. But no matter how your internal biological clock works, the lack of sleep will make your physical and mental health affected. Here are 10 health consequences of sleep deprivation:
- Lack of sleep is associated with a higher risk of certain cancers
According to a 2003 study on shifts, sleep deprivation and interruption of sleep schedules, it is associated with an increased risk of certain cancers, most notably colon cancer and breast cancer.
- Lack of sleep makes the wound on the skin hard to heal and the skin is also easier to age
According to a University of Wisconsin study, poor sleep quality is closely related to chronic skin problems. Studies have also found it difficult to heal sun-damaged skin or other factors in sleep deprived people, so the skin of these people has more signs of aging than normal people.
- Lack of sleep makes it hard to control desire, potentially leading to unhealthy behaviors and weight gain
People who do not get enough sleep seem to fall into a “hypnotic” state, causing them to lose control of themselves and not resist high-calorie foods. They crave more food and eat unhealthy meals. Researchers think the hormonal imbalance caused by lack of sleep is the cause of this hypnosis. Hormonal imbalance is also associated with high BMI and obesity.
- People feel more lonely after sleepless nights – and loneliness makes them more sleepy
Researchers have found that young people who are deprived of sleep are less likely to socialize than others. And those who report that they have poor sleep also tend to say they are lonely. It seems that only making things worse, people who feel lonely do not tend to go to bed early, which leads them to a vicious cycle.
- Lack of sleep increases the risk of heart disease and type 2 diabetes
There is a lot of evidence that lack of sleep has a negative effect on the heart. When researchers kept some volunteers awake for 88 hours, their blood pressure increased. Even participants who are allowed to sleep 4 hours a night also have a high heart rate when compared to those who get eight hours of sleep. C-reactive protein concentration, a sign of heart disease risk, also increased in people who lacked sleep. In addition, other studies show that lack of sleep affects metabolism, increasing the risk of insulin disorders, leading to type 2 diabetes.
- Sleepiness makes you uncomfortable and irritable
You may not realize it yourself, but the truth is that you will be more irritable with things around if you didn’t get enough sleep the night before. Research has also shown that people’s cognitive ability is impaired when they are deprived of sleep, leading to a lot of mistakes. And because of that, they are easily irritable to themselves.
- Lack of sleep can cause hallucinations, very dangerous when participating in traffic
As you know, never drive when you’re sleepy. Even if you try to keep your eyes open, studies show that sleepless people report hallucinations of the tunnel (seeing themselves walking into a dark tunnel with flickering light at the end of the road), looking at the double (see everything split into 2 like drunken people) and blurred vision. These hallucinations are especially dangerous if you are driving.
- People with sleep deprivation respond slowly to everything around them
One more reason to reinforce that you should not drive when you are sleep deprived. Your reaction speed is seriously affected when not getting enough sleep. Therefore, it is not surprising that lack of sleep makes people more clumsy. Research shows that a sleepless night will make surgeons increase the risk of errors by 20-32%. Athletes who play games that require precision like shooting also make more mistakes when they lack sleep.
- The immune system does not work well when you are tired
You know the great things that the immune system does for you, when you are accidentally injured or you have to be in a germ environment, such as going to the hospital to see an ill person or an office that is having flu. But do you know that it’s not just chronic insomnia that even a sleepless night can weaken the immune system. Lack of sleep makes the risk of colds increase 3 times. It even affects the vaccination, making the vaccine less effective.
- People who lack sleep are less happy and more susceptible to depression.
In a classic study led by Nobel laureate psychologist Daniel Kahneman, a group of 909 women were asked to record details of their sleep logs and moods as well as daily activities. While the difference in income of up to $ 60,000 has little effect on their happiness, scientists found bad sleep the night before as one of two factors that could ruin the mood of the day. the next day. Another study found that women with higher quality sleep were happier in marriage. In contrast, insomnia doubles the risk of developing depression. So treatment for depression often includes treatment for insomnia.
