Nothing is cozier than a hug. Whether it’s a mama-daughter embrace or a sweet squeeze with your significant other, hugs make us feel warm and fuzzy inside. But they do more than make us feel good: Research suggests that hugs can deliver some real health benefits, from easing stress to lowering blood pressure. Here, four ways a warm embrace can be good for both your mind and body.

They help us feel supported

Hugs don’t just bring us closer to others in a literal sense: they also trigger the release of oxytocin, a chemical associated with bonding behaviors. “Studies show that people feel better and more connected to their partner when they hug or touch frequently,” Terri Orbuch, PhD, a relationship expert and author of 5 Simple Steps to Take Your Marriage from Good to Great, told Health in an email. “When we physically connect through a hug, it makes us feel emotionally and psychologically connected to the other person, it calms us, and it shows support.” No harm in that.

They may lower your risk of infections

Who knew cuddling could help keep you sniffle-free? In a 2014 study from Carnegie Mellon University, researchers found that stressed-out people (who are more likely to get sick) had a reduced risk of infection after being exposed to a common cold virus if they felt like they had adequate social support in their lives and received more frequent hugs.
