It's a HUG!
Your skin needs reassurance. It has been used as a therapeutic tool, because it takes us back to our earliest experiences in life. We don't touch enough in our lives. We are taught not to touch. But our skin hungers for touch. It makes us feel good. Here is where quality and quantity count. When you hug, you give permission to hug. Listen to your body, trust it, it is wise. Tell the person you need a hug. Ask for one. When we hug, we share a commonness. You can hug anywhere you are comfortable.
Here is good advice: 4 hugs a day for survival, 8 hugs a day to maintain balance, 12 hugs a day to grow. Be generous with your hugs.
