Show Yawn for Your Health. Doctor Naegeli, professor of medicine medi-cine at Liege university, commends the practice of yawning as a physical teviver. A good yawn, the professor maintains, is excellent for the lungs, and for all the breathing organs as well. Hut there is an art in yawning, he says, just as there is an art in breathing. Every yawn should be as deep as possible, so as to bring all the muscles of the throat and chest Into action, and also to fill the lungs with a current of fresh air. Doctor Naegeli has known of many cases in which a sore throat has been alleviated by persistent yawning, says the London Chronicle. |
