Daytime sleepiness blamed on obesity, depression

June 13, 2012

Now a couple of new studies say the main driver behind this excessive sleepiness are obesity and depression.

Researchers say the link is a complex one. They say obesity and weight gain affect sleep, and poor sleep affects weight from a physiological and behavioral perspective.

There are well-publicized risks associated with excessive daytime sleepiness that include accidents caused by drowsy driving and workplace injuries.

The findings were presented Wednesday at the Associated Professional Sleep Society's meeting.
