How is insomnia harmful to your body?

Not getting enough sleep not only makes people mentally exhausted but also increases the risk of cancer.

In an interview with The NewYork Times, billionaire Elon Musk worried friends and investors when they revealed that they worked too much and spent too little time sleeping. Tesla’s CEO himself admits his lifestyle is not healthy.

Life habits of billionaire Elon Musk.

Working too much, Elon Musk did not sleep enough for 7 hours a night, increasing the risk of chronic disease and death. In a recent interview with the New York Times, Elon Musk, CEO of Tesla Company revealed he worked 120 hours a week, equivalent to more than 17 hours a day. This greatly affected the life and health of the 47-year-old billionaire.

“That’s not really great,” Musk admitted. “There are times when I don’t leave the factory for 3-4 days.”

This summer, Musk missed his birthday and just went out for a few hours to attend his brother’s wedding. He also said he never took time off work for more than a week, except for malaria in 2001.

If the numbers above are correct, Musk only has 7 hours a day without working. As such, he certainly fell into a lack of regular sleep.

Matthew Walker, a neurologist, from California University Berkely specializes in studying the effects of sleep deprivation on the body. Sharing with Business Insider, he said: “Sleepless, life is shorter. The quality of your life will also decrease.”

In the US, the US Centers for Disease Control and Prevention recommends that adults aged 18 to 60 sleep at least 7 hours a night. However, Walker’s research shows that sleep time should be about 7-8 hours. Resting below this level will lead to long-term health damage, even death.

In fact, lack of sleep depletes natural killer cells, also known as NK cells, a form of lymphocyte (white blood cell) that helps protect the body from disease. Sleeping 4-5 hours a night can reduce this cell count by 70%.

Sleep deprivation also increases the risk of chronic diseases like Alzheimer’s, obesity, and diabetes. Sleeping 5-6 hours a night for a week is enough to cause prediabetes. In the long term, the heart, blood vessels, and kidneys are also affected.

Not to mention, people who sleep less susceptible to cancer. Currently, scientists have recognized insomnia is a factor that promotes the risk of colon cancer, breast cancer, and prostate cancer.

Of course, not everyone is the same. Some people sleep 6 hours and stay healthy, but they only account for about 1% of the population and carry the BHLHE41 gene very rarely.

Lack of sleep could destroy the body.

When you’re not sure if you have the BHLHE41 gene, you should get enough sleep to protect your health. If you have trouble sleeping, try to use Walker’s method of always staying in bed for 8 hours, even if you don’t sleep at all. This also helps improve mental, physical and labor productivity.

Matthew Walker, a neurologist, from the University of California, Berkely (USA), thinks that sleeping less, the shorter the life cycle. Although sleep time varies individually, most adults still need 7 to 8 hours of sleep a night.Here are the consequences you suffer if you lack sleep, according to Business Insider.

Increased risk of cancer.

Less sleep and interruption causes a higher risk of cancer, especially colon cancer and breast cancer.

Reduces the ability to restore skin and cause skin aging.

According to research from the University of Wisconsin (USA), lack of sleep and chronic skin diseases are closely related. When exposed to the sun or other harmful factors, the skin cannot recover well and shows more signs of aging.


Due to hormonal imbalance, people with sleep deprivation increase appetite leading to obesity. In addition, they have difficulty controlling behavior that leads to self-harm.


Research that just doesn’t get enough sleep makes the ability to socialize worse. They feel lonely, worse, these people often sleep poorly, making themselves stuck in a vicious cycle.

Short-term, long-term memory and reduced learning ability.

Some studies show that sleepless adults have difficulty remembering vocabulary and improving their skills.

Contact with Alzheimer’s.

Getting enough sleep reduces the amount of Beta-Amyloid, a protein that is closely related to Alzheimer’s disease.

The risk of cardiovascular disease increases.

Blood pressure, heart rate and the concentration of reactive C protein are higher when sleeping less, thereby increasing the risk of cardiovascular diseases.

Easy to get irritated.

Almost everyone feels cranky after a sleepless night, even with everyday situations.

Vision problems and hallucinations.

Lack of sleep leads to syringe vision, double vision, and blurred vision. The longer you stay, the more likely you are to suffer from refractive errors and hallucinations.

Slower and more clumsy response.

Sports players, officers, and surgeons all perform poorly with lower accuracy when sleep is not guaranteed.

Immune system decline.

Only one night of insomnia also causes the body’s immune mechanism and ability to absorb vaccines. According to one study, sleepers are not three times more prone to catching colds.

Reduce sexual desire.

Sleep helps replenish testosterone levels in both sexes. Reducing libido, sexual dysfunction and sleep apnea are three risks when you lack sleep.

The risk of type 2 diabetes.

Wake up when your body needs sleep-disrupting your body’s mechanism, eventually leading to insulin resistance (pre-diabetes) and type 2 diabetes.

Make the wrong decisions.

Many research results that just go to sleep are not enough to affect the ability to make decisions and implement preset plans. This is also part of the cause of the Chernobyl nuclear disaster, the Exxon Valdez oil spill and the shuttle Challenger explosion.

Easy to lose focus.

If you want your brain to stay focused, try to get enough sleep. Lack of concentration can lead to many disastrous traffic accidents because drivers or pilots are short of respite.

Increased urinary excretion.

This phenomenon comes from a mechanism to increase urine excretion at night without sleep.

Muscle weakness.

Muscular injuries due to living and practice become more difficult to heal. According to the study, the body releases growth hormone to heal wounds during sleep.

Poor pain tolerance.

Chronic pain will be worse because the lack of sleep increases sensitivity or even causes the body to ache.

Transforming gene activities.

A 2013 study found poor sleep led to abnormalities in gene activity. For those who sleep less than 6 hours a night, more than 700 genes are abnormal, especially those that control the immune system and respond to stress.

Other health problems.

Intestinal inflammation, irritable bowel syndrome, headache, and many other serious diseases can be caused by lack of sleep. Even some people may snore and are more prone to apnea during sleep.
