Teenagers who don’t get enough sleep may wake up to worse consequences than nodding off during chemistry class. According to new research, risk of being obese by age 21 was 20 percent higher among 16-year-olds who got less than six hours of sleep a night, compared with their peers who slumbered more than eight hours. (The Centers for Disease Control and Prevention recommends nine to ten hours of sleep for teenagers.)
Researchers at the Mailman School of Public Health at Columbia University and the University of North Carolina Gillings School of Public Health are the first to examine the effect of sleeplessness on obesity in teenagers over time, providing the strongest evidence yet that lack of sleep raises risk for an elevated BMI. Results appear in Journal of Pediatrics.
Shakira F. Suglia, ScD, assistant professor of Epidemiology at the Mailman School, and colleagues analyzed health information from more than 10,000 American teens and young adults, ages 16 and 21, as part of the National Longitudinal Study of Adolescent Health. Information on height and weight and sleep was collected during home visits in 1995 and 2001.
Nearly one-fifth of the 16-year-olds reported getting less than six hours of sleep. This group was 20 percent more likely to be obese by age 21, compared to their peers who got more than eight hours of sleep. While lack of physical activity and time spent watching television contributed to obesity, they did not account for the relationship between sleeplessness and obesity.
“Lack of sleep in your teenage years can stack the deck against you for obesity later in life,” says Suglia. “Once you’re an obese adult, it is much harder to lose weight and keep it off. And the longer you are obese, the greater your risk for health problems like heart disease, diabetes, and cancer.”
“The message for parents is to make sure their teenagers get more than eight hours a night,” adds Suglia. “A good night’s sleep does more than help them stay alert in school. It helps them grow into healthy adults.”
Daytime sleepiness and fatigue are known to affect what and how people eat, by altering appetite and stimulating cravings. Energy levels may also play a role. For the sleep-deprived, ordering calorie-dense fast food is easier than preparing a nutritious meal. Information on what the teens ate was not captured in the surveys, although it could play a role. Future research may look whether, for example, soda consumption is a factor in sleeplessness and, in turn, obesity. (A 2013 study by Suglia found young children who drink soda are more likely to have behavioral problems.)

Yoga Body: The Origins of Modern Posture Practice
Yoga is so prevalent in the modern world–practiced by pop stars, taught in schools, and offered in yoga centers, health clubs, and even shopping malls–that we take its presence, and its meaning, for granted. But how did the current yoga boom happen? And is it really rooted in ancient Indian
practices, as many of its adherents claim?
In this groundbreaking book, Mark Singleton calls into question many commonly held beliefs about the nature and origins of postural yoga (?sana) and suggests a radically new way of understanding the meaning of yoga as it is practiced by millions of people across the world today. Singleton shows
that, contrary to popular belief, there is no evidence in the Indian tradition for the kind of health and fitness-oriented ?sana practice that dominates the global yoga scene of the twenty-first century. Singleton''s surprising–and surely controversial–thesis is that yoga as it is popularly
practiced today owes a greater debt to modern Indian nationalism and, even more surprisingly, to the spiritual aspirations of European bodybuilding and early 20th-century women''s gymnastic movements of Europe and America, than it does to any ancient Indian yoga tradition. This discovery enables
Singleton to explain, as no one has done before, how the most prevalent forms of postural yoga, like Ashtanga, Bikram and Hatha yoga, came to be the hugely popular phenomena they are today.
Drawing on a wealth of rare documents from archives in India, the UK and the USA, as well as interviews with the few remaining, now very elderly figures in the 1930s Mysore ?sana revival, Yoga Body turns the conventional wisdom about yoga on its head.
