One of the greatest observers of human things (not physiological), says, in another language, “Where there is sun there is thought.” All physiology goes to confirm this. Where is the shady side of deep valleys, there is cretinism. Where are cellars and the unsunned sides of narrow streets, there is the degeneracy and weakliness of the human race—mind and body equally degenerating. Put the pale withering plant and human being into the sun, and, if not too far gone, each will recover health and spirit.
It is a curious thing to observe how almost all patients lie with their faces turned to the light, exactly as plants always make their faces turned to the light; a patient will even complain that it gives him pain “lying on that side.” “Then why do you lie on that side?” He does not know,—but we do. It is because it is the side towards the window. A fashionable physician has recently published in a government report that he always turns his patients’ faces from the light. Yes, but nature is stronger than fashionable physicians, and depend upon it she turns the faces back and towards such light as she can get. Walk through the wards of a hospital, remember the bed sides of private patients you have seen, and count how many sick you ever saw lying with their faces towards the wall.
