Massage and Scuba Diving Because massage stimulates the circulatory system, i.e. "shakes the soda bottle", a surface interval of four hours is recommended prior to massage if you dive below 80 feet and a surface interval of 6 hours is recommended if you dive below 120 feet, to allow the body to sufficiently off-gas. If you plan to dive more than 2 tanks per day, please save your massage for a day you are not diving.
80 feet = 4 hour surface interval 120 feet = 6 hour surface interval
