In a new study researchers have found the weight gain among teens may also be due to late bedtimes.

The study was conducted by University of California-Berkeley and Columbia University. Data of more than 3,300 teens and young adults were studied over a period of fifteen years at different intervals. Details of the findings are published in the October issue of Sleep journal.

According to study author Lauren Asarnow, obesity is on the rise among teenagers and adults as well and simultaneously there is an epidemic of lack of sleep and going to bed late too.

Teens' Weight Gain Linked To Late Bedtimes

Asarnow is a doctoral candidate at the University of California, Berkeley. His findings revealed every one hour of lost sleep is linked to a 2.1 point increase in body mass index (BMI).

Sleep Health Foundation sleep psychologist Dorothy Bruck said those who have a later circadian rhythm risk themselves of developing mental health issues like depression.

He added these days many teenagers are concerned about weight gain and hence it is suggested they should make sure going to bed at a reasonable early time.

Asarnow said her findings have important implications as sleep is modifiable and parents should shift bedtime in their young ones and this could give them good sleep habits. This will further result with preventing weight gain over time.

Few earlier studies have found chronic pattern of late sleep times also results with metabolic disturbances.
