Daily sessions on a Rebounder—a soft, flexible mini-trampoline—may boost the immune system and help detoxify the body. According to the Well Being Journal, bouncing temporarily increases white blood cell levels, and helps organs release accumulated toxins. The theory is that when the body is suspended in air, gravity pulls on cells. When the body lands, the cells get squeezed, causing toxins to be released. At the very least, bouncing is a gentle but effective low-impact exercise. “It’s an efficient way to increase oxygen intake, get an emotional lift, and gain more energy,” says Marel Norwood, PhD, of Seattle, Wash., a social psychologist specializing in stress management. “I used to have to run 30 minutes to get that lift. Now I feel it after seven minutes of bouncing,” says Norwood. Health benefits run the gamut from alleviating the symptoms of osteoporosis to strengthening muscles. But probably the best payoff is simple: It’s fun.
