The concept of SNOEZELEN was defined in the late 1970s by two Dutch therapists, Jan Hulsegge and Ad Verheul while they were working at the De Hartenberg Institute in Holland, a center for people with intellectual disabilities. At the Institute’s annual summer fair, Hulsegge and Verheul set up an experimental sensory tent filled with simple effects such as a fan blowing shards of paper, ink mixed with water and projected onto a screen, musical instruments, tactile objects, scent bottles, soaps, and flavorful foods. It was a tremendous success, especially with low-functioning clients who demonstrated positive verbal and non-verbal feedback. The therapists called this multi-sensory experience “snoezelen,” a contraction of the Dutch verbs “snuffelen” (to seek out or explore) and “doezelen” (to relax).
