There are cases of nervous pain at menstruation that are aggravated by heat and diminished by cold. I knew such a case where a girl at school, suffering with menstrual pain, alarmed teachers and friends by wringing towels out of cold water and laying them over her abdomen. But the alarm subsided when they saw that the pain soon passed away under the cold application. The girl was one in whom there were no local congestions, but great nervous exhaustion and heat always increased her sufferings, while cold allayed. I have read that a woman should not bathe or change her underwear while menstruating. I cannot see how soiled clothing can be more healthful than that which is clean; and if well-aired, I should no more object to your putting on clean underwear than to your changing your dress. Most especially would I advise a frequent change of napkins, in order to remove those which are soiled from their irritating contact with the body. A full bath during menstruation would, for most people, be unadvisable, but the cleansing of the private parts is imperative. For this, tepid water, with good soap, may be used daily or oftener. Other parts of the body may be rubbed with a wet cloth, followed by vigorous, dry rubbing. Cleanliness at all times is certainly a mark of refinement. You should use good sense and not run out in thin slippers on wet or cold ground; but if your feet get wet through accident, keep in motion until you can make a change of shoes and stockings. There is little danger from wet feet to those in good health, if they keep in vigorous motion. As to other rules, they are those that pertain to the care of health at all times: loose clothing, deep breathing, wholesome food, plenty of sleep, sunlight, pure air, exercise according to your strength, and, above all, serenity of mind, accepting the fact of physical womanhood, together with a recognition of its sacredness and dignity. As a minor item, I would suggest that the napkins be fastened to straps that go over the shoulder and are then joined together in front and back to an end piece, on each of which a button is sewn. Buttonholes in the napkins at the corners, diagonal from each other, will make them easily attached or removed. The napkins should be of a material that is quickly absorbent of the flow. Cheesecloth is cheap, and can be burned or otherwise disposed of after using. It may be protected by an outer strip of unbleached muslin which is almost water-proof.
