A massage isn’t just a treat—it can be part of staying healthy. Receiving a 45-minute Swedish massage can greatly lower levels of two key inflammation-promoting hormones, according to a study in The Journal of Alternative and Complementary Medicine. “Massage may decrease inflammatory substances by [appropriately] increasing the amount of disease-fighting white blood cells in the body,” says Mark Hyman Rapaport, M.D., co-author of the study. “It may also lower stress hormones. Either way, these inflammation-lowering results can be seen after just one massage.”
