Sleep for Your Waist – a Study in Journal Sleep

Sleep for Your Waist – a Study in Journal Sleep

Studies have shown that the insufficient sleep leads to weight gain.

Dr. Sperry and colleagues reviewed 23 studies of 56,259 adults and reported (August edition of SLEEP) that there indeed exists a significant, inverse relationship between sleep duration and waist circumference. 

It is a huge problem. In the United States in 2001, only 38% of adults reported getting eight hour of sleep per night, and, by 2009, that percentage had dropped to 28%. Several studies have demonstrated that insufficient sleep is associated with increased risk for poor physical health (including hypertension, metabolic syndrome, type 2 diabetes, and hypercholesterolemia) and mental health (including depressed mood, anxiety, and cognitive deficits). In parallel with the decrease in sleep, the prevalence of obesity has increased. In 2009–2010, 78 million US adults age 20 y and older were obese.

Despite significant heterogeneity related to sleep comparison method across the 22 studies, there was a consistent pattern of findings of a significant negative relation between sleep duration and central obesity, providing empirical support that shorter sleep durations are linked to an increase in central obesity.

In conclusion, cross-sectional studies done in various countries, demonstrate a significant negative relation between sleep duration and waist circumference, indicating shorter sleep durations may contribute to central obesity. This study gives us one more reason for us to commit ourselves to getting 7-8 hours of sleep every night. Please do everything you can to make sure you get a sound sleep of 7-8 hours every night. 

Thanks.

Sleep Well, Live Well.
