Children should be taught, in simple, easy lessons, the rudiments of physiology and hygiene. The work should be begun by the mother in the home and should be faithfully carried forward in the school. As the students advance in years, instruction in this line should be continued until they are qualified to care for the house they live in. They should understand the importance of guarding against disease by preserving the vigor of every organ. They also should be taught how to deal with common diseases and accidents. Every school should give instruction in both physiology and hygiene. TEd 118.2
There are matters not usually included in the study of physiology that should be considered—matters of far greater value to the student than many of the technicalities commonly taught under this subject. As the foundation principle of all education in these lines, the young should be taught that the laws of nature are the laws of God—as truly divine as are the precepts of the Decalogue. God has written on every nerve, muscle, and fiber of the body the laws that govern our physical organism. Every careless or willful violation of these laws is a sin against our Creator. TEd 118.3
The influence of the mind on the body, as well as of the body on the mind, should be emphasized. The electric power of the brain, promoted by mental activity, vitalizes the whole system, and is thus an invaluable aid in resisting disease. This should be made plain. The power of the will and the importance of self-control, both in the preservation and in the recovery of health, should be emphasized. Likewise, the depressing and even ruinous effect of anger, discontent, selfishness, or impurity should be shown. On the other hand, the marvelous life-giving power to be found in cheerfulness, unselfishness, and gratitude should be emphasized. TEd 118.4
There is a physiological truth in the scripture, “A merry [rejoicing] heart does good, like medicine.” Proverbs 17:22. TEd 118.5
As the mechanism of the body is studied, attention should be directed to its wonderful adaptation of means to ends, the harmonious action and dependence of the various organs. As the interest of the students is thus awakened, and they are led to see the importance of physical culture, much can be done by the teacher to secure proper development and right habits. TEd 118.6
