I believe in the regular warm tub bath, or cold sponge followed by a good rubbing all over the body at this time, together with nine or ten hours' sleep, and light, nourishing food without stimulant. If the bowels are active, it often lessens the pain considerably, and it is very important that every girl attend to this if she has any regard for her health. There are a few abnormalities of the menstrual function which I will not take the space to state here. Before leaving the subject, I wish to impress upon the reader that most abnormalities, such as too little or too much flow, or very great exhausting pain are usually caused, not by any disease of the generative organs, but more often a disturbance of the general health, which can often be treated and cured by building up the system. Every girl should learn the laws of menstruation and its hygiene and have a full understanding of the same. The menstrual function occurs only in the female at puberty, but at the same time there comes to both boys and girls, or male and female, a mysterious and impelling influence, which has great power over the lives of both during the adolescent period unless they understand and control it. This is known as the Sexual Impulse. CHAPTER IV. SEXUAL IMPULSE—PART I. The sexual impulse is the strongest force in all living creatures. It is this that animates the struggle for existence; it is this that attracts and unites two beings, that they may reproduce their kind; it is this that inspires man to the highest and noblest thoughts; it is this also that inspires man to all endeavors and achievements, to all art and poetry; this impulse is the creative instinct which dominates all living things and without which life must die. If, then, this force, this impulse plays so strong a part in our lives, is it not necessary that we know something about it? * * * * * At the time of puberty there comes both to boys and girls, two impulses—one, the desire to touch or caress; to come in contact with, to write or to speak to, an individual of the opposite sex. This impulse is much stronger in girls than in boys. The other is the impulse that impels the individual to discharge the accumulation of ripe sex cells, and relieve himself of the nervous tension which this accumulation produces. This impulse is stronger in boys than in girls. One writer states that this is an unconscious desire for relief from physical congestion, not differing greatly from the sense of relief which the emptying of the bladder or rectum produces. * * * * * These two impulses together, according to Moll, constitute the Sexual Impulse, and this constitutes the foundation upon which love, the greatest of all emotions, is based. * * * * *
