Laughing for health
Popular wisdom has it that laughter is the best medicine. A growing number of scientific studies are now providing proof.
The effect of laughter on physical and mental well-being is the purview of gelotology, the study of humour and laughter. This new field of study has found that the longer and more often you laugh, the greater the health benefits.
Various kinds of stimuli cause laughter, explained Michaela Schaeffner, head of the Munich-based Association of German Laughter Therapists. They include emotional stimuli such as a good mood while on holiday, mental stimuli like a funny joke and physical stimuli such as tickling.
“When it comes to mental and physical stimuli, the key is an element of surprise, a sense of contrast,” Schaeffer said. When the brain receives an appropriate stimulus, it sets laughter in motion. “More than a hundred muscles are involved, from facial to respiratory,” noted Carsten Niemitz, director of the Institute of Human Biology and Anthropology at the Free University of Berlin.
Breathing during laughter is deeper than usual, which affects the whole body. “More oxygen flows to the body’s cells, the bronchia are ventilated, catabolic processes are advanced, muscles relax, the heart and circulation are stimulated,” said Michael Titze, lecturer at the March Institute of Psychotherapy in the Brandenburg town of Baruth. In addition, laughter boosts healing. A laughing person’s brain blocks production of stress hormones such as adrenaline and cortisone. “When someone laughs, more serotonin or ‘the happiness hormone,’ is secreted. So if you laugh a lot, you’ll feel better,” Niemitz said.
Good laughter-training methods include regional laughter club meetings, laughter seminars and laughter yoga. “Laughter yoga begins by activating the laughter muscles via various playful exercises,” Schaeffner said. The exercises have to do with making sounds, facial expressions and body movements as well as breathing techniques and stimulating the diaphragm.
