How to become an A human

Research shows that sleep regulates hormones that control the appetite.

Researchers at the National Center for Disease Diseases in Bergen have now investigated the relationship between sleep length and body mass index (BMI) among Norwegian children aged 10-12 years.

BMI is a measure of obesity, you can also find out if you are overweight using the life-hip ratio.

5000 children examined

– The findings showed that sleep length is associated with obesity in children at this age, says sleep researcher Yngvild Danielsen, who has analyzed data from the survey Children in Bergen, where 5,000 children are involved.

A previous study in Sweden showed that stress in the family gave overweight children.

Hormones control the appetite

– The curve showing the relationship between sleep and obesity in children is U-shaped. That is, both short and long sleep lengths are associated with obesity. As for the two groups, children who sleep a little and children who sleep a lot, we think the explanation mechanisms behind are different. One explanation is that sleep length affects hormone production, and especially the hormones leptin and ghrelin, which regulate appetite, says Yngvild Danielsen.

Leptin is a hormone that tells the brain when the body has had enough food, while ghrelin is a hormone that increases appetite.

– When you do not get enough sleep, the leptin level decreases, which causes you to not experience satisfaction after eating. Sleep deprivation also causes ghrelin levels to rise, which increases appetite, explains Michael Breus, PhD at the Atlanta School of Sleep Medicine, according to WebMD.

American Research

Two independent American studies have shown these relationships.

A study at the University of Chicago in Illinois measured the leptin level and ghrelin level of 12 healthy men, who also recorded the experience of hunger and appetite.

The 12 men first performed two days of reduced sleep, then two days of prolonged sleep. Everything while the hormone levels and experiences of starvation and appetite were measured and logged.

The study showed that sleep restraint lowered the leptin level and raised the ghrelin level. The appetite also went up. The desire for food with a high degree of carbohydrate and high calorie content increased by 45 percent.

The study conducted by Stanford University in California in collaboration with the University of Wisconsin concluded that 1,000 volunteers reported how many hours they were sleeping each night before doctors measured their leptin and ghrelin levels and the fat percentage in their body mass.

The result showed that those who slept less than eight hours each night had low leptin levels, high ghrelin levels and a higher fat percentage.

Sleep amount and fat percentage matched. Those who slept the least had the highest body weight.

May be due to borderline

The survey in Bergen has not included data about children’s parents.

– Previous research has shown that there is a relationship between parents’ BMI and children’s BMI, which is explained, among other things, by genetics. It may also be thought that there is a connection between the border setting parents practice for the children’s sleep and diet, “says Yngvild Danielsen.

If you have problems with sweets, there are good tips to help you control the need for sweets.

Also applies to adults

Through the research program HUSK (Health Survey in Hordaland), Reidun Ursin, Professor of Sleep Physiology at the Faculty of Medicine at the University of Bergen, together with five other researchers, has considered the relationship between sleep and BMI. Almost 9000 people aged 40 to 45 answered questions about their sleep habits.

The researchers in HUSK found that little sleep gives increased BMI and increases the tendency to obesity.

Our studies show that people who sleep for six hours a night are more likely to be obese than those who sleep 7-8 hours in the night, Reidun Ursin says to address. no.

Remember that you can adjust your daily rhythm if you are among those who struggle with sleep loss when the time rings in the morning. Sleep researchers have previously recommended five different strategies to combat insomnia.

20 minutes extra sleep gives lower BMI

Robert D. Vorona, MD at the American Virginia Medical School, has conducted a survey of 1,000 patients divided into the normal weight group (BMI under 25), overweight (BMI 25-29.9), obesity (BMI 30-39.9) and extreme obesity (BMI over 40). The average BMI was 30 and the average age was 48.

Vorona found that short sleep time was associated with high BMI, with the exception of the extreme obesity group. Patients with obesity and overweight slept less than patients with low BMI.

The difference was 16 minutes sleep average per night, or nearly two hours per week.

Those who worked night shift slept on average 42 minutes less than others.

– Americans sleep too little and are corpulent. Our findings suggest that no extra sleep is needed, 20 minutes extra each night may coincide with lower BMI, researchers write in their conclusion.
