People who sleep less than seven hours a night are 2.9 times more likely to be obese than people who sleep eight to nine hours per night according to a new study from researchers at Texas Tech in Lubbock, Texas, USA. Conclusion

Conclusion : Adults should sleep 8-9 hours to maintain optimal weight

“Our study demonstrates that short sleep times have an association with obesity in adults with chronic medical problems and that chronic disease and attendant therapies and/or changes in physical activities do not obscure this relationship,” Kenneth Nugent, MD, lead author of the study was quoted as saying.

“This study suggests that adults should sleep eight to nine hours per night to maintain optimal weight,” he added.

 

Subjects

Subjects : 200 people

The study analyzed data from a survey of 200 people attending internal medicine clinics who completed a survey regarding sleep habits, lifestyle characteristics, and medical diagnoses.

 

Comments

Comments : Several studies have shown lack of sleep is associated with increased body weight

A number of studies have found that less sleep is associated with higher body weight.

I believe this is one of the dozen or so factors that has lead to the obesity epidemic in the last 30 years.
