I was reading comments on this blog a while back and came across a knee pain sufferer parsing his symptoms for meaning. One thing that helped with the pain, he noted, were hot showers.
Yup. Makes sense.
Well, I thought I’d share my analysis of this phenomenon (“The Hot Shower Effect”), as others have no doubt noticed the same thing. Of course, my standard disclaimer: I’m not a doctor (nor do I play one on TV).
Anyway, I think hot showers confer a similar feel-good benefit as light stretching (which made my bad knees feel better). Namely, they loosen the muscles in the leg, so that when you sit, for example, your kneecap isn’t pushed so tightly against the damaged cartilage in your joint.
Stress would naturally work in the opposite direction, by tightening the muscles and placing the joint under more irritating force.
Of course there’s most likely an additional effect at work that has to do with mood and brain chemicals. Stress correlates with unhappiness, anger, frustration, anxiety -- all negative emotions. A hot shower is tranquil and relaxing.
Having a bad knee is a difficult, depressing experience. Whatever can get you out of that zone even for a little while -- taking a hot shower, meditating, laughing at the antics of some squirrel on YouTube -- should be helpful, even if it there’s more you need to do eventually to address the root cause of your pain.
