Barak figured out several years ago that heavy king and corn snakes produce a relaxing kneading sensation. She says that once people get over any initial misgivings, they find physical contact with the snakes to be stress relieving.
"Some people said that holding the snakes made them feel better, relaxed," she said "One old lady said it was soothing, like a cold compress."
The size of the snakes depends on the type of massage - the larger ones are said to alleviate deeper muscle tensions and the smaller ones create a 'fluttering' effect. All are the snakes used are non-venomous.
