Pet therapy with cats can also help ease the blues. Kitty owners can be less lonely and have higher morale than those who don’t have a cat—likely because cuddling with an animal can unleash oxytocin, the body’s “love” hormone.
Being with a dog for five minutes can lower your levels of cortisol, a stress hormone. The effect is so pronounced that, in one study, frazzled people said they felt it was more relaxing to be around their pets than their spouses.
It even works at the office: Research found that people who brought their dogs to work had lower stress levels throughout the day (meanwhile, levels rose among their canine-less colleagues).
There’s more: Walking with a dog—versus cruising alone—has been linked to more social interactions, such as conversations with strangers (like, say, that cute guy at the park).
Pet aficionados may also have lower levels of heart-hurting cholesterol and fatty triglycerides.
The really great news? If you live with a Fifi or Fido, you may need fewer overall visits to the doctor and have a healthier ticker. One study found cat owners were less likely to die from heart disease than those who live sans felines. Another found that dog owners were nine times more likely to be alive one year after a heart attack than those without dogs.
