I agree that laughing reduces stress hormones, and at least in the short-term reduces CO2 levels.Suikerbuik said:https://raypeatforum.com/forums/posts/93940/ Rather a sign of being in stress most of the time. The laughing will reduce stress hormones. And laughing also happen to lower CO2, especially noticeable in those who are metabolically limited.
I have a suspicion, however, that it can also result in useful activation and relaxation of the diaghragm in some circumstances. Reduced stress hormones also tends to reduce hyperventilation. For people who tend to chronically hyperventilate with active chest muscles, inactive diaphragm, and chronically high stress hormones, as long as the additional temporary hyperventilation involved in the active laughing is not too severe, the longer-term effect of a good laugh may be to reduce hyperventilation and raise CO2 levels.
This could be another component of 'laughter is the best medicine'. I think this is consistent with my experience, but it is speculation on my part, not something I've seen studies on on. Does that seem feasible to you?
