Is it true that sleeping too much will make you fat? Sleeping too much makes you fat, right?

Too little sleep can lead to obesity Experts advise you to sleep more. There has always been a saying in the past that being fat is due to sleeping too much.

But a new study has made a startling finding: there is a big correlation between sleep time and obesity. In the future, experts can prescribe a good remedy for people who want to be slimmer, and that is to sleep.

Scientists have found that people who sleep less than 4 hours a night are 73% more likely to be obese than those who sleep 7 to 9 hours a night. Health experts generally recommend that people get 7 to 9 hours of sleep a day. People who sleep an average of 5 hours a night are obese 50 percent of the time, while those who sleep an average of 6 hours a night are just over 23 percent obese.

Steven Helmsfield, Ph.D. from Columbia University in the United States, said: "This may be a boon for obese people, and we will advise them to sleep more in the future." "Dr. Helmsfield is a physician at St. Luke-Roosevelt Hospital in New York.

Dr. Helmsfield and Columbia epidemiologist James Ganwitz led the study, which will present their findings at an upcoming meeting of the North American Society for Obesity Research. Their data comes from a survey of about 10,000 adults by the National Health and Nutrition Survey (NHANES) in the '80s. The survey included long-term tracking of healthy habits, and the researchers modified the data based on other factors that may affect obesity, such as exercise habits, and concluded that sleep has an effect on obesity.

"The conclusions of the study may be contrary to our common sense," Ganwitz said. Generally speaking, sleep tends to be obese because people consume relatively few calories when they rest.

But once they wake up, they will be fed up in large quantities. Experts believe that the risk of obesity is different due to the slow effect of sleep deprivation on the body's food-seeking "circuit". Dr. Helmsfield said

A growing body of scientific evidence suggests a link between sleep and various nerve conduction that regulates food intake. Sleep deprivation lowers levels of leptin, an appetite-suppressing blood protein that may also affect how the brain feels when the body is getting enough food. In addition, sleep deprivation can also increase Grehlin levels.

Grehrin is a substance that whets your appetite. Dr. Philip Eklin, a sleep expert at the University of Arizona in the United States, said that sleep deprivation can also harm the body's "management function" - the person's decision-making ability. Dr. Acklin is the Medical Director of the Tucson Gap Hot Springs Sanatorium.

The spa provides health and weight management training, especially for the company's top management. "One of the ways I do this is to tell them to adjust their sleep time and increase it from six to seven hours," Dr. Acklin said. ”

Sleep is important, but it's not always better to sleep longer.

As we all know, sleep helps to eliminate physical fatigue and maintain abundant energy, but it must be the opposite! For the average adult, it's normal to sleep 7 to 9 hours a day, and long sleeps will make you :

1: Easy to gain weight.

As the time of sleep increases, the time for activity will be relatively reduced, energy expenditure will be reduced, and excess calories will be converted into fat and stored in the body, causing obesity.

2: Cause fatigue and headaches.

If you often work overtime and stay up late on weekdays, and sleep until noon or afternoon of the next day on weekends, it will disrupt the original biological clock and affect the quality of sleep, resulting in feeling tired after waking up, and the more you sleep, the more tired you become.

Why is it easy to sleep too much in winter?

The weather is cold. In winter, the weather is cold and cold, and I am reluctant to get up in the morning, especially on weekends, I like to nest in the warm quilt all day long, and I sleep too much unconsciously.

Decreased vitality. In the cold winter, many people will reduce the number of outdoor exercises, so that the amount of exercise will be greatly reduced, and the whole person will appear less energetic and easily sleepy, resulting in too much sleep.

Blood sugar fluctuates greatly after a meal.

In winter, people prefer to eat some hot stews, but these foods generally take longer to cook, and foods that take longer to cook and have higher temperatures have higher GI values. After eating high-GI foods, the human body has a large blood sugar load, which makes people easily drowsy, and sleepiness can also occur during the day.

Sleep is the need of life, so people can't live without sleep, and the lack of sleep every day must be made up, otherwise they will be punished, much like a debt must be repaid.

If you sleep less than 6 hours a day, although it increases heat consumption, the metabolic rate in the body will be disturbed, insulin secretion will increase, leptin secretion will decrease, resulting in increased fat synthesis, more appetite, and it is very easy to become obese.
