Early and prolonged sleep reduces the risk of obesity – Oyster-France evening edition

According to a recent study conducted in 26 developed countries, the rhythm of sleep has a strong impact on weight control. Insomnia due to short nights and late sleep has been linked to obesity. Descriptions.

Sleeping well is good for the line. Research has already established that insomnia increases the risk of heart disease, memory loss and inattention. Obesity is a public health issue. It can have serious health consequences such as diabetes, heart disease or cancer.

Chinese researchers a Public health study, Released June 30, 2021 Journal of the American Medical Association (JAMA), Which shows that going to bed earlier and avoiding short nights will help you control your weight better.

In the group of participants, almost half expressed trends in weight gain. An effect unrelated to the circadian rhythm of a sleep rhythm, i.e. the internal clock of the human body is about 24 hours based on a day and night cycle.

The body regulates itself once it respects its circadian rhythm. If you stay awake for a long time, the body will work longer to store fat, without using it all.

The World Health Organization (WHO) recalls that abdominal obesity is defined as a waist circumference of more than 102 cm for men or more than 88 cm for women. When the body mass index (BMI) value exceeds 30, we are talking about general obesity. “Accumulation of stored reserves in adipose tissue”, National Institute of Health and Medical Research (INSERM) recalls.

Inserm accuses of disrupting the biological clock: “It regulates the organism’s various functions and metabolism for more than about 24 hours. Adequate sleep, irregular diet or even night work can disrupt this clock and increase the risk of gaining too much weight.”

Poorly regulated sleep leads to fatigue and depression, which is very conducive to snacking. In addition, the poorly rested body finds that its hormonal system is affected by a disorder of hormone deficiency and an increase in appetite-stimulating hormone, the site notes. Better health .

More than 130,000 participants

According to a Chinese study published in Journal of the American Medical Association (JAMA), “One-third of adults sleep less than six hours a night”. Researchers also note that the American Academy of Sleep Medicine and the Sleep Research Society recommend that adults sleep at least seven or more hours a night to improve optimal health, including weight.

According to data from 60 research centers in 26 developed countries, 136,652 participants, 60% of whom were women, were found between 2005 and 2009. 20% of them are suffering from overall obesity and 27% are suffering from abdominal obesity.

Letters are established between short nights of less than 6 hours and general obesity, while long sleeps promote greater fat storage in the stomach. Obesity is short and late (after midnight) sleep, just like sleeping during the day, just before 8pm.

The link between insomnia and weight gain has been around for a while, which is hell of a vicious circle! If very short and late-starting nights promote obesity, weight gain can promote insomnia. A study published in the April 2020 issue of the journal Blos Biology Showed it “Being overweight promotes poor sleep”.
