Fewer Americans are drinking alcohol, according to a new report.
A study by researchers at Boston University analyzed data from surveys filled out by over 8,000 Americans who have been followed for over 50 years.
They found Americans are drinking less beer and more wine, and hard liquor has remained the same. More people are reporting they're non-drinkers now, and alcohol consumption appears to lessen with age. However, no change was reported in alcohol-related disorders.
Researchers say the shift towards "moderate drinking" may mean Americans are moving in a healthier direction, but efforts to prevent alcohol disorders are still needed.

And in other medical news…
How much sleep children and teens get may influence their risk for obesity.
Researchers in Pittsburgh conducted sleep studies on over 300 children ages seven to seventeen.
They found those who got an hour less than the average amount of sleep had double the risk for obesity. Spending an hour less in REM sleep, the type linked to dreaming, tripled the risk for being overweight.
Researchers say they don't know why sleep and obesity are linked but hey suspect changes in hormones from sleep loss may play a role.
