The Swedish massage is the most common and best-known type of massage in the city. Based on the Western concepts of anatomy and physiology—as opposed to energy work on "meridians" or sen lines that are the focus in Asian massage systems—therapists utilize this type of massage to stimulate circulation, flush the circulatory system, release tight muscles, restore range of motion, and to relieve pain. The Swedish massage is a good fit for beginners. Most people get a 50- or 60-minute Swedish or deep tissue massage, but 75 or 90 minutes will give the therapist more time to work the muscle tissue and achieve results. A Swedish massage can be slow and gentle, or vigorous and bracing, depending on the therapist's personal style and what he or she is trying to achieve.
