Lack of sleep can cause serious harm to the body

Guide: Do you know that lack of sleep can cause some harm to the body?

Everyone knows that sleep is vital to the human body. According to research, people with insufficient sleep and poor sleep quality are prone to work injuries and accidents.

Below, the experts will tell you that the 9 major adverse effects caused by lack of sleep.

Let’s go and have a look.


It is easy to cause accidents. Insufficient sleep has become one of the important factors causing traffic accidents today. The reaction speed of a person driving in confusion is equal to the reaction of drunk driving.

According to relevant statistics, in the United States within one year, there were 100,000 accidents and 1,500 traffic casualties caused by fatigue driving.

Most of these perpetrators are young people under the age of 25.


Making people ignorant sleep plays a decisive role in a person’s thinking and learning ability. Lack of sleep affects people’s cognitive process in many ways.

First, lack of sleep can harm people’s attention, alertness, concentration, reasoning, and problem-solving skills, which can make your learning less efficient.

  In fact, during the night, each sleep cycle plays a role in “consolidating” memory in the brain.

But if you don’t get enough sleep, during the day, you may not remember what you have learned and what you have experienced.


Causes serious health problems Sleep disorders and chronic sleep deprivation can increase your risk of developing these diseases: heart disease, heart attack, heart failure, arrhythmia, high blood pressure, stroke, diabetes.

It is estimated that 90% of insomniacs (people who are characterized by difficulty falling asleep and being awake) are also associated with other health problems.

  4 Insufficient sleep can lead to depression through time, sleep deprivation and sleep disorders can lead to depression.

Insomnia and depression are inextricably linked.

According to a survey of 10,000 people in 2007, those who have insomnia are five times more likely to develop depression than those who do not have insomnia.

In fact, insomnia is often a precursor to depression.

  Insomnia and depression are complementary, and lack of sleep can exacerbate depression, which in turn makes it harder to fall asleep.

From a positive perspective, treating sleep problems can help alleviate depression, and vice versa.

  5 Accelerate skin aging Presumably most people have experienced sallow skin and puffy eyes after not sleeping for several nights.

It is proved that long-term lack of sleep can lead to dull skin, wrinkles, and dark circles.

When you don’t get enough sleep, your body will release more stress hormone cortisol.

Excessive leather alcohol breaks down collagen in the skin, which keeps the skin smooth and elastic.

Deep sleep repairs skin tissue.

  6 Stunning and forgetting to make your memory clearer?

This requires you to get enough sleep every day.

Researchers in the United States and the United States have unanimously determined that a brain region known as the “spike wave” is specifically responsible for consolidating memory.

This brainwave is also responsible for the information learned from the transmission of the hippocampus to the cerebral cortex.

Most of the “spikes” appear only when people are deeply sleepy.

  7 Insufficient sleep can increase weight and lack of sleep may increase the sense of drought and increase appetite.

According to relevant data, people who sleep 6 hours a day may even become obese than those who sleep 7-9 hours a day.

Chronic hormones in the stomach stimulate hunger and leptin signaling in the brain, thereby suppressing appetite.

Shortening sleep time reduces the secretion of leptin and increases the level of obesity hormones.

Insufficient sleep is enough to stimulate appetite, and it also stimulates the body’s desire to sorghum and tremble.

  8 Increasing the risk of death British researchers have observed how the sleep patterns of more than 10,000 British civil servants have affected their mortality rates for more than two decades.The results showed that those who lost sleep from 7 hours to 5 hours or longer had nearly twice the risk of death from illness.

In particular, the lack of sleep doubles the chance of death from cardiovascular disease.

  9 Influencing Judgment The lack of sleep affects our understanding of things. Because we cannot properly assess and act wisely, this will affect people’s reasonable judgment of events.

People who are deprived of sleep seem to be particularly prone to judgment errors.

In this world where the pace of life is gradually accelerating, sleeping less becomes a symbol of glory.

But sleep experts say that the act of reducing sleep is wrong, and you may not be able to pay for it.

Especially if you are working through the military’s judgment-critical work, the impact of lack of sleep can be a big problem.
