American scientists argue that overweight people who have managed to lose weight can enjoy better sleep quality. The results of the study were presented at the American Heart Association Scientific Sessions.
Researchers from Johns Hopkins University School and Yale University School of Nursing found that reducing weight in people struggling with excess weight or even obese had a positive effect on the effectiveness of night rest. In this regard, the reduction of belly fat is of particular importance.
We found that improving sleep quality was significantly linked to weight loss overall, and specifically shedding belly fat, reports senior study author Kerry Stewart.
The subjects were subjected to two weight loss programs, one of which was based on the use of a special diet, and the other included physical exercise in addition to the diet. Additionally, they completed questionnaires for measuring sleep quality, which included such problems as: insomnia, sleep apnea, daytime fatigue, restless sleep, excessive sleep, general sleepiness, and the need for sedation.
The participants of the study managed to lose weight by an average of about 7 kg and lose about 15 percent. abdominal fat. As a result, they could enjoy better sleep quality, which was shown by 20 percent. higher scores on the questionnaire scale.
There were also no differences between the groups. Whether exercise was included in the weight loss program or not, the quality of sleep improved.
A key ingredient in improving the quality of sleep in our study turned out to be a reduction in overall body weight, in particular belly fat, regardless of age, gender, or the group that was slimming through a diet or diet combined with exercise, concludes Stewart.
The researcher emphasizes that good-quality sleep is very important to maintaining physical and mental health. It enables the proper functioning of the circulatory system. Chronic sleep disorders increase the risk of developing high blood pressure, heart attack, stroke and cardiac arrhythmias. (PAP)
