The neck should be comfortably clad, and kept at the normal temperature as nearly as possible. It is the sudden change from an over-heated neck and chest to that of the opposite extreme that causes the trouble. The boy who, with scarf tightly wrapped about his neck, fights his mimic battle with snowballs until the perspiration flows from every pore, and then throws aside jacket and scarf while he rests, and the girl who, in furs and tippet, skates until she becomes thoroughly heated, and takes off her wraps while she stops to breathe, have many imitators among the older boys and girls in the world. As to the proper amount of covering for the neck, much depends upon habit, and not a little upon individual requirement. The important point is to preserve uniformity, and to guard against sudden changes. The sailor with neck freely exposed is fully as exempt from colds as is the soldier whose neck is more warmly clad. If they should suddenly exchange their manner of dress, the result would be disastrous to both. The important blood-vessels that supply the face, head, and brain, and the jugular veins which return the blood to the heart, all pass through the neck. The clothing about the neck should therefore be loose, so as to allow the freest passage of the food, breath, and blood, and the fullest movement of the head. =Male Attire.=--While appearance demands that the outer clothing should be neat-fitting, comfort and health require that it should be sufficiently loose to admit of the freest movements of the body. It should be as light as possible to insure proper protection from the cold. Weight does not always count for warmth. Many persons prefer light flannels as outer garments for warm weather. The trousers should be supported from the shoulders by suspenders. Belts involve more or less constriction of the abdomen, and are injurious. Men suffer greater disadvantage from their use than women. The practice of wearing a belt during the summer months is especially objectionable. =Female Attire.=--Healthful and proper clothing implies, (1), the protection of the body against extremes of heat and cold, and the maintaining of an equable temperature in every part; (2), the absence of all superfluous material and needless weight; and (3), the non-interference with the normal functions of the body. Mrs. Woolson, a writer on Dress and Health, says: The limbs have not half the amount of covering which is put upon the trunk of the body. Many garments have no sleeves, or sleeves that terminate a few inches below the shoulders. As to the legs, the clothing which should increase in direct ratio to the distance from the body to the feet, diminishes in the same ratio. Thin drawers, thinner stockings, and wind-blown skirts which keep up constant currents of air supply little warmth to the limbs beneath. The feet, half-clad and pinched in tight shoes, are chilled in consequence.
