I recently heard that a massage is equivalent to sleep on a 1 hour of massage to 4 hours of sleep basis. I suppose this could be true, but my google fu is not strong enough to reveal more than claims that appear to be advertising. What is the Straight Dope on this, O teeming dozens?
I’ve had a number of relaxing massages, and it does feel very restful afterwards. But I do not notice needing less sleep as a result.
