Friends with Benefits: How Pals Keep You Healthy

It's often tempting to vegetate at home in front of the TV or computer screen. But consider what doctors say is key to staying happy and healthy: socializing.

"More Americans in the last 20 years say that they have fewer close friends or people in their lives with whom they can discuss important matters," says Duke University sociologist Lynn Smith-Lovin. "What ties to a close-knit group of people does is create a safety net."

Doctors agree, and say that a good chat or a regular girls' or guys' night out can do even more.

"Feeling cared for and supported within a social network is particularly important for women in fostering self-care," says Todd Jackson, PhD, author of a 2006 study linking high levels of social support and community involvement with healthier diet, exercise and sleep habits, among other positive effects.
