Sleeping teens' sugar
|
A good night's sleep seems to be good for an obese teen's blood sugar. At The Children's Hospital of Philadelphia, researcher Dorit Koren saw that in measurements of 62 obese teens with an average age of 14, who spent time at the hospital's sleep lab.
Koren was watching blood sugar because, in overweight or obese teens, higher glucose levels could indicate a risk of developing diabetes:
"Teenagers who slept about seven and a half to eight and a half hours had the lowest glucose levels. Those who slept less - and, to a lesser degree, those who slept more - had higher glucose levels." (12 seconds)
Koren says it's another reason for teens to get enough sleep.
The study in the journal Diabetes Care was supported by the National Institutes of Health.
