Hugs help release oxytocin, which makes you feel good and can reduce anxiety. Getting more hugs can mean better sleep because it makes you feel calm and secure. Hugging may improve your immune system, helping you get sick less often and less severely. There's no denying the power of a hug. If you’ve ever said you’ve felt starved for touch, you’re actually not that far off. The same areas of our brain that are satisfied by eating are also satisfied by human touch, including hugs.
