Now, when you hear "skin hunger" you might think: malnutrition. Skin needs vitamin D, E, oils, moisture, etcetera to be healthy. But what skin hunger refers to emotional starvation from lack of psychical touch.
( This article talks about how touch affects metabolism, kind a cool: http://www.nytimes.com/1988/02/02/science/the-experience-of-touch-research-points-to-a-critical-role.html?pagewanted=all)
It's just like stomach hunger in the way that you don't know you're hungry until you're empty.
The sensation of skin hunger is hard to describe. When its at its worst it feels like the very surface of my skin sort of bristles or stings very subtly. A strange sort of ache almost. But this is a bodily sensation too, the muscles feel anxious but without energy, the heart feels clenched and lonely.
This is a pretty prevalent problem in the digital age. People don't need to physically communicate anymore. But what has resulted are young adults age 20+ who are emotionally starved because they can go months and years without meaningful human touch. Basically, no hugs. I read somewhere (you can look it up yourself) that there are hugging clubs where people go to get hugs because they are so deprived. One person acts as a life-hug-guard to make sure things stay appropriate.
As a single lady, this is a basic fact of life. I go to work and I sit alone in a small climate controlled room for 8 hours then go to a empty house and occupy myself with projects. At church I get to shake hands. Yippee.
To remedy this I sometimes beg for back tickles from family.
To be clear, tickling is the gentle caress of the finger tips or nails not a distracted pat or rub that tapers off after thirty seconds.
One time while watching TV with my niece, her hair tickling my chin almost put me asleep because it felt so good.
