According to a recent study carried out by researchers from Johns
Hopkins University in the U.S, it was found that people who lost a stone in
weight, and reduced about 15 percent of their waistline, slept much better
while overweight individuals continue to have sleep-related issues besides
various other problems.
The study was carried out on 77
people who were overweight or obese and had either type 2 diabetes or
pre-diabetes, who were then randomly assigned to one of two groups. One group
participated in exercise training and went on a diet while the other group just
followed a diet.
The participants were required to
fill out a questionnaire on sleep survey at the start and end of the study to
identify sleep problems, including sleep apnea, insomnia, daytime fatigue,
restless sleep, excessive sleep or sleepiness. They were also required to
mention if they required sedatives to help them sleep. The body mass index and
abdominal fat of the subjects were
measured at the start and end of the survey.
On an average, both groups lost
about 15lb of weight; they also lost about the same amount of abdominal fat
which was measured with the help of magnetic resonance imaging (MRI). Also,
there was an improvement in the sleep score of both the groups by 20%. Although
a variety of sleep problems were reported by both the groups but no single
problem was projected prominently.
Kerry Stewart, Professor of
Medicine at the Johns Hopkins University School of Medicine and Director of
Clinical and Research Exercise Physiology said that an improvement in sleep
quality was discovered to be associated with weight loss in general and loss of
belly fat in particular. She added that good sleep is vital for optimal
physical and mental health, as well as for the proper functioning of the heart.
Lack of proper sleep has been linked to high blood pressure, heart attack and
It is a well known fact that obese individuals
are known to suffer from sleep-related problems. It is therefore important to
maintain an optimum weight and this can be brought about by adopting a healthy
lifestyle, which includes regular exercising and a healthy diet.
