Swedish massage employs a series of long, gliding strokes, kneading of the muscles, and vibrational taps which are so common when one thinks of massage. Five basic strokes gliding, kneading, vibrations, friction and hacking are all applied in the direction of the heart in order to encourage blood circulation and the natural disposal of toxins in the body. Massage oils are used to reduce friction and achieve smooth, long and deep strokes. Essential oils are sometimes used in order to tap into a client's olfactory senses (sense of smell). In order for a Swedish massage to be as effective as possible it is recommended that the client disrobe to their own level of comfort that will also allow the proper use of oil. By using draping techniques, body parts are only uncovered when they are being massaged.
