Most people sleep more than a third of their lives in their lifetime. Sleep is closely related to our health. Lack of sleep affects many aspects of our lives.
1.Prone to accidents
Insufficient sleep has become one of the important factors causing traffic accidents today. The reaction speed of a person driving while confused is equivalent to that of drunk driving. According to relevant statistics, in the United States in one year, 100,000 motor vehicle accidents and 1,500 traffic casualties were caused by fatigue driving. The majority of these perpetrators were young people under the age of 25.
According to research, people who suffer from poor sleep and poor quality of sleep are also prone to work injuries and accidents. According to a survey, workers who frequently complain about lack of sleep during the day are more likely to have work-related injuries and frequent accidents. And they have taken more sick leave as a result.
2. Make people dull
Sleep plays a decisive role in a person’s thinking and learning ability. Lack of sleep affects people’s cognitive processes in many ways. First of all, lack of sleep can damage people’s attention, alertness, concentration, reasoning ability, and problem-solving ability, which can lead to your learning efficiency.
Secondly, at 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 experienced.
3.Causes serious health problems
Problems with sleep disorders and chronic lack of sleep can increase your risk of these conditions: heart disease, heart attack, heart failure, arrhythmia, high blood pressure, diabetes. It is estimated that 90% of patients with insomnia (people characterized by difficulty falling asleep and awakening easily) also have other health problems.
4.Lack of sleep can cause depression
Over time, lack of sleep and sleep disorders can lead to depression. Insomnia is inextricably linked to depression. According to a 2007 survey of 10,000 people, those with insomnia are five times more likely to develop depression than those without insomnia. In fact, insomnia is often one of the symptoms of depression.
Insomnia and depression are complementary, and lack of sleep can worsen the state of depression, which in turn makes it more difficult to fall asleep. From a positive perspective, treating sleep problems can help alleviate depression and vice versa.
5.Speed up skin aging
Presumably, most people have experienced yellow skin and puffy eyes after not sleeping for several nights. But this proves that chronic lack of sleep can cause skin dullness, wrinkles, and dark circles. When you don’t get enough sleep, your body releases more of the stress hormone cortisol. An excess of cortisol breaks down collagen in the skin, which keeps the skin smooth and elastic. Deep sleep repairs skin tissue.
6. Make people forgetful
Want to make your memory clearer? This requires you to get enough sleep every day. American researchers have determined that brain waves in one area of the brain are specifically responsible for consolidating memory. This brain wave is also responsible for transmitting the learned information from the brain’s hippocampus to the cerebral cortex. Most of these brain waves occur when people sleep deeply.
7. Lacking sleep can increase weight
Insufficient sleep may increase hunger and increase appetite. According to relevant data, people who sleep less than 6 hours a day are more likely to become obese than people who sleep 7-9 hours a day. Hunger hormones in the stomach can stimulate hunger and leptin signals in the brain, thereby suppressing appetite. Shortening the sleep time will reduce the secretion of leptin and increase the level of hunger hormones. Not only does lack of sleep stimulate appetite, but it also stimulates the body’s desire for high fat and high carbohydrates.
8.Increased risk of death
British researchers have observed how the sleep patterns of more than 10,000 British civil servants have affected their mortality for more than two decades. The results showed that those who reduced their sleep from 7 hours to 5 hours or less had a nearly doubled risk of death from the disease. In particular, the lack of sleep doubles the risk of death from cardiovascular disease.
9.Influence judgment
Lack of sleep affects our understanding of things, and because of the inability to accurately assess and act wisely, it will affect people’s ability to make sound judgments about events. People who are deprived of sleep appear to be particularly prone to misjudgment. In a world where the pace of life is accelerating, sleeping less is becoming a symbol of glory. But sleep experts say it’s wrong to get less sleep, and you may lose more than you gain. The effects of lack of sleep can be a big problem, especially if you are doing a judgment-focused job.
