Current research Abnormal sleep times favor obesity
It is probably already known to most people that too little sleep is not healthy for the body. Researchers have now found that both too much and too little sleep can increase the likelihood that sufferers will develop obesity or obesity.
The researchers from the University of Glasgow found in their current research that too much or too little sleep can increase the likelihood that people will become overweight or even obese. The doctors issued a press release on the results of their study. In addition, they were published in the journal "American Journal of Clinical Nutrition".

In the study, the British experts found that abnormal sleep patterns increase the risk of becoming overweight if people are already genetically predisposed to obesity. This effect was independent of diet, health or socio-demographic factors, explain the authors. However, the physicians at the University of Glasgow found no clear link between sleep duration and body weight in people at low genetic risk of obesity.
Duration of bedtime and its effects studied
For their study, the researchers considered both the effects of too short a sleep of less than seven hours per night, and the effects of a bedtime more than nine hours. They also took into account the change in sleeping hours during shift work and so-called nap during the day, say the experts.
People with a high genetic risk for obesity should pay attention to normal bedtime
The results of this study show that in people with a high genetic risk for obesity, short and long sleep times, the already existing risk of obesity continues to increase compared to people who have a normal sleep duration of between seven and nine hours per night.
Long sleeping subjects weighed about four kilograms more
Late risers with a risk of obesity were about four kilograms heavier, explain the doctors. On average, if such people slept too briefly, they were on average two kilograms heavier compared to those with a similarly high genetic risk for obesity but a normal sleep duration.
Shift work and nap also affect the weight
The results are based on data from nearly 120,000 UK participants. The subjects' data did not show a general, obvious association between sleep duration and body weight in people who had a low genetic risk for obesity, the researchers explain. However, it became clear during the investigation that shiftwork or a nap during the day could have a significant adverse effect on body weight if there was already a heightened genetic risk of obesity.

Some people are not so badly affected by the negative effects
The overall influence of negative sleep characteristics on body weight in people with a low genetic risk of obesity is much lower. Such people just seem to be better able to cope better with the negative effects despite bad sleep habits, the experts speculate.
Our sleep can have a significant impact on body weight
People with a high genetic risk of obesity seem to be more worried about certain lifestyle factors in general to maintain a healthy body weight, explains author. Carlos Celis from the University of Glasgow. The study's findings suggest that sleep is another important factor in maintaining healthy body weight, which has a significant impact on our diet and physical activity. (As)
