There has been a large number of trials that show massage has health and wellness benefits such as reducing blood pressure, improving sleep and improving psychological states. I have a big table summary of the trials in our article Massage for health and wellness .
The main issue though is to get these results most of the trials used very frequent massages over a period of time: usually daily or at least three times per week. If using professional services this puts those benefits beyond the reach of most, but they are readily available with one of our massagers and some good advice.
