Women who had only 6 hours of sleep per day, stand at 12 increased risk of major. that women who get 5 hours of sleep or less have 15 percent higher risk of becoming obese during the study period of 16 years, compared to women who sleep more.
Sleepless nights can also make the symptoms of conditions such as chronic lung disease worse. The authors believe their research to be the first to investigate the relationship between bedtime and BMI longitudinally in an observational study.Ī study by the University of Bristol, published in March, found that if you need a lie-in at weekends to make up for lack of sleep in the week, you may be at risk of obesity and type 2 diabetes.Īs well as lack of sleep being linked to obesity, night shift work has also been linked to being severely overweight, because sleeping during the day burns fewer calories than at night.Įxperts suggest that a mismatch between the body’s internal circadian clock and sleep patterns can disrupt normal metabolism. Net World Directory: Sleepless Nights Causes Weight Gain : Back to the main health blog page. Respiratory system If you wake up throughout the night and start to suffer from sleep deprivation, your body will be more vulnerable to respiratory illnesses such as flu and the common cold. Visceral fat is deposited deep inside the abdomen. Sleep and circadian variables were determined via self-reported measures at all three waves and investigators measured height and weight at each stage. Findings from a randomized controlled crossover study led by Naima Covassin, Ph.D., a cardiovascular medicine researcher at Mayo Clinic, show that lack of sufficient sleep led to a 9 increase in total abdominal fat area and an 11 increase in abdominal visceral fat, compared to control sleep. The study incorporated three waves of data from the National Longitudinal Study of Adolescent Health between 19, with the youngest participants aged 12 and the eldest 32. Lead author Lauren Asarnow, a doctoral candidate at the University of California, Berkeley, said: “The results are important because they highlight adolescent bedtimes, not just total sleep time, as a potential target for weight management concurrently and in the transition to adulthood.”
The paper said this made the case for future research on the effect of later bedtimes upon dietary habits. Like other studies before it, new research from Northwestern University finds that lost sleep can cause changes in your metabolism that make you store more fat, lose muscle and be more likely to. However, the relationship between bedtime and BMI was significantly reduced with the inclusion of fast food consumption. The authors said they were surprised to find that the relationship between bedtime and BMI – calculated using an individual’s height and weight – was not significantly changed or moderated by total sleep time, exercise frequency or screen time. Although BMI (body mass index) does not distinguish between lean muscle and fat, and the researchers from the University of California, Berkeley, and Columbia University did not measure waist circumference, the study will raise further concerns about the reported relationship between lack of sleep and obesity.
