Here's a reason to give someone you love a big, warm hug!
Hugging me increase production of feel-good endorphins in your body, which strengthens your immune system.
Endorphins also reduce your risk of infection by buffering the effects of stress, which can increase your susceptibility to disease.
Hugging also stimulates your thymus gland, which is responsible for the regulation and balance of white blood cells.
So hug away, it's good for you!
