The researchers invited 30 young men and women of normal weight to participate in the trial. In the first trial, the subjects were assigned to sleep for 9 hours every night for 5 consecutive days. In the second trial, the subjects were scheduled to sleep only four hours a night for five consecutive days. During the two trials, their meals were strictly controlled for the first four days, but they could eat as they wanted on the last day.
The results showed that the subjects consumed an average of 2600 calories a day. When they get enough sleep, they only eat the equivalent of 2500 calories on the last day, but when they don’t get enough sleep, they can eat the equivalent of 2800 calories. Studies have shown that people who don’t get enough sleep eat more, but don’t burn more calories, so they tend to get fat.
1. Less sleep will increase food intake. The most healthy sleep is to sleep for seven hours every day. If not enough sleep, it will seriously affect the balance of hormones in the body, make the digestive system disordered, so as to increase food intake, so as to increase the storage of fat, and finally make the body fat. When people are in deep sleep, the growth hormone secreted by the brain will guide the body to convert fat into energy consumption, but if the sleep time is reduced, coupled with the accumulation of heat in the body, the hormone secretion can’t catch up with the speed of fat growth, the body will naturally grow fat.
2. The sleep period is a period of deep sleep, in which the body burns the most calories. If you sleep too little and your body can’t relax well, the shorter the duration of REM sleep will be, so that you can’t burn more calories and become obese after a long time.
These are the reasons for obesity caused by lack of sleep. Normal people should guarantee about 8 hours sleep every day, so that they can achieve the most ideal state of health, and will not cause obesity. If you are suffering from insomnia, you should pay attention to the routine, exercise more, eat light, keep a cheerful mood, and relax yourself before going to bed.
Over time, sleep deprivation and sleep disorders can lead to depression. Insomnia and depression are inextricably linked. Lack of sleep can exacerbate depression, which in turn can make it more difficult to fall asleep. From a positive point of view, the treatment of sleep problems can help alleviate depression, and vice versa.
Presumably most people have experienced a few nights after not sleeping, skin wax yellow, puffy eyes. But this proves that a long-term lack of sleep can lead to dull skin, wrinkles and dark circles. When you don’t get enough sleep, your body releases more stress hormone cortisol. Excess cortisol breaks down collagen in the skin, which keeps the skin smooth and elastic. Deep sleep can repair skin tissue.
Want to make your memory clearer? This requires you to get enough sleep every day. Researchers in the United States and France agree that a brain region called “sharp ripples” is specifically responsible for memory consolidation. This brainwave is also responsible for the transmission of information from the hippocampus to the cortex. And “sharp ripples” mostly appear when people are deep asleep.
Sleep plays a decisive role in one’s thinking and learning ability. Lack of sleep affects one’s cognitive process 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 low learning efficiency.
Sleep disorders and chronic sleep deprivation can increase your risk of these diseases: heart disease, heart failure, arrhythmia, high blood pressure, stroke, diabetes. It is estimated that 90% of insomniacs (people who are difficult to fall asleep and easy to wake up) have other health problems.
Lack of sleep may increase hunger and appetite. According to relevant data, people who sleep less than 6 hours a day are more likely to be obese than those who sleep 7-9 hours a day. Hunger hormones in the stomach stimulate hunger and leptin signals in the brain, thus inhibiting appetite. Shortening sleep time will reduce the secretion of leptin and increase the level of hunger hormone. Lack of sleep not only stimulates appetite, it also stimulates the desire for high fat and carbohydrate.
Lack of sleep will affect our understanding of things, because of the inability to accurately assess and act wisely, it will affect people’s reasonable judgment of events. People deprived of sleep seem to be particularly prone to miscalculation. In an increasingly fast-paced world, less sleep is becoming a symbol of glory. But sleep experts say it’s wrong to make sleep less, and you may not be able to pay for it. Especially if you’re in a judgment heavy job, the impact of sleep deprivation can be a big problem.
British researchers have looked at how sleep patterns in more than 10000 British civil servants affect their mortality rates over more than two decades. The results showed that those who fell asleep from seven hours to five hours or less were nearly twice as likely to die of disease. In particular, lack of sleep doubles the risk of death from cardiovascular disease.
