A new research led by the researchers from University of California revealed that sleeping late at night may lead to weight gain in adults. The researchers have recognized a connection between sleep and BMI.
For the research, they analyzed longitudinal data from a group of nearly 3,300 youths and adults in the US and found that they gain 2.1 points on the BMI index after losing every hour of sleep. Furthermore, screen time, exercise and the duration of sleep did not mitigate this BMI increase.
The lead author of the research, Lauren Asarnow, a doctoral student in UC Berkeley’s Golden Bear Sleep and Mood Research Clinic said, “These results highlight adolescent bedtimes, not just total sleep time, as a potential target for weight management during the transition to adulthood.”
Researchers aimed on three time periods – the onset of puberty, the college-age years and young adulthood. They compared the bedtimes and BMI of teenagers.
Adolescents in the study reported their bedtimes and sleep hours while researchers calculated their Body Mass Index (BMI) based on their height and weight. The reports of the study suggested that youth who go to bed earlier will “set their weight on a healthier course as they emerge into adulthood,” Asarnow said.
The research was published in the journal Sleep.
