Loneliness doesn’t just feel bad. It’s actually bad for you. Researchers at Brigham Young University found that having few friends is as dangerous for you as smoking more than a pack a day or drinking heavily. And it can actually be worse for you than being obese or a couch potato.
The connection’s not clear, but a strong social network can reduce your risk of stress and depression. When you’re feeling good, you’re more likely to take care of yourself.
