Hugs are awesome. They help in a number of ways. Hugs cause a chemical reaction that lowers our heart rate and stress levels, so they are helpful on a physical level. Hugs also help us mentally, emotionally and sometimes even spiritually. Hugs can make us feel cared for, loved, safe, excited, wanted, etc.

I think online hugs can be effective as well. I imagine the physical effects are lessened, but I'm sure there's some sort of reaction if you can visualize an online hug being real. It probably just depends on how 'real' it feels to you.

Hugs to you and all who want or need them.
