Lack of sleep has for quite some time been connected to obesity, but the main culprit is not eating at night, but impairing metabolism, new research shows.
People who sleep less increase the body’s ability to store fat.
Research results that are considered scientific evidence have shown that sleep disturbance affects the usual rhythm of the body, increasing the risk of a wide range of health problems from heart to diabetes.
Jonathan Sedererness, an analyst at the University of Uppsala, Sweden, said that the consequences of the study show an irreplaceable function sleep has in the functioning of the human body.
“Sleeping is not only about saving energy and regenerating the body, it also has many other functions,” says Jonathan.
Judging by the results, lack of sleep and how it affects obesity and overeating. Absence of sleep prompts the interruption of the hormone that controls appetite and a feeling of satiety. Therefore, those who sleep less, have more time to eat, are more tired to exercise, and have less self-control when it comes to the temptation to eat unhealthy snacks.
The latest study provides new evidence on how sleep deprivation has a direct impact on metabolism and balance between muscle and fat.
During the study, which was carried out in Science Advances, 15 healthy volunteers attended normal sleep and sleepless nights. Samples of fat, blood and adipose tissue were also given during the non-sleeping session.
Researchers have found that after a sleep-deprived session, human fat tissue shows a change in cell-related gene activity, increasing their tendency for lipid absorption and proliferation.
In contrast, muscle scientists have noted the reduced levels of structural proteins that each body needs to maintain and build muscle mass. Therefore, people who sleep less have less muscle mass and more fat in the body.
