There are many ways to de-stress and spas specialize in this. Exercise is an excellent de-stresser. Bathing in hot water is a de-stresser. Massages are for many the ultimate de-stresser. At spas people typically leave their outside world behind, they slow down and their bodies become more relaxed. A spa has nurturing staff and there is lovely food that doesn't intoxicate but rather revitalizes. I think that what spas do is help us get back to who we really are and connecting at that level is always romantic.
