Sleep Increases Your Pain Threshold
If you want to tough out physical pain, hit the sack. That’s the suggestion of a 2012 study from the journal Sleep, which divided study subjects into two groups, one that slept nine hours nightly and another that slept an average seven each night. Researchers then tested how long each participant could hold their finger to a radiant heat source. Subjects in the nine-hour group withstood the heat about 25 percent longer. It’s not clear why more sleep led to more pain tolerance, but the findings echo similar results in other studies and suggest that a long night’s sleep is a potent pain reliever.
