One of my preferred news compilation websites, Alternet.org, just published a piece, originally from the UK Independent (I believe), on the relation of emotions, personal interactions, and similar ‘moods’ on health. Anastasia Stephens, in the article, ‘How Your Mood Affects Your Health,’ runs through in very cursory fashion a whole host of research on the effects of things like laughing, stress, arguments, and crying on the human immune systems, healing, and the like.
The article has a lot of fun little research summaries, unfortunately, without links to the actual research reports or anything deeper about the studies. But there’s warnings about how arguing affects healing:
A half-hour argument with your lover can also slow your body’s ability to heal by at least a day. In couples who regularly argue, that healing time is doubled again. Researchers at Ohio State University discovered this by testing married couples with a suction device that created tiny blisters on their arm. When couples were then asked to talk about an area of disagreement that provoked strong emotions, the wounds took around 40 per cent longer to heal. This response, say researchers, was caused by a surge in cytokines — immune-molecules that trigger inflammation. Chronic high levels of these are linked to arthritis, diabetes, heart-disease and cancer.
Or another personal favorite:
Scientists at the University of California have discovered that laughter relaxes tense muscles, reduces production of stress-causing hormones, lowers blood pressure, and helps increase oxygen absorption in the blood. Cardiologists at the University of Maryland Medical Center found laughing can actually reduce the risk of heart attack by curbing unwanted stress, which can destroy the protective lining of blood vessels. A good giggle also burns calories since it’s possible to move 400 muscles of the body when laughing. Some researchers estimate that laughing 100 times offers an aerobic workout equivalent to 10 minutes on a rowing machine or 15 minutes on an exercise bike.
