Nor shall any one be allowed to sleep in our kitchen. It is a very unhealthful and uncleanly custom to let the servants sleep in the kitchen. There should be no sleeping in a room where food is prepared. By morning the air of a sleeping room is always charged with bad matter given off from the lungs of the sleepers. Sleeping rooms have a chance for ventilation during the day, and all these vapors are replaced by pure air. But there is no time in the morning to change the air of the kitchen. The food must be prepared in the midst of all the bad gases that have gathered there during the night. This brings us to think of what proper sleeping arrangements should be. Not enough attention is given to the subject in this country. The nights are so hot that people are careless. Many grown people and nearly all children sleep on or close to the floor. This custom is a great source of sickness. If the floor is of bamboo, the bad air from the earth rises through it at night. There is always a draft across the floor, from doors and from windows, and from spaces in the floor itself. When we are asleep the body is relaxed, the pores of the skin are open, and we are in every way less able to resist chills and the bad effects of impure air. Sleep is a condition of helplessness, and we should protect ourselves in it. A serious cause of disease, which people are just beginning to understand, is the mosquito. We have only lately come to know that this insect is the direct cause of the malaria which is so common, and so dangerous, here. Malaria is a germ disease. That is, it is a disease caused by germs which get into the blood. The germ of malaria is a parasite which lives on the body of the mosquito. We can imagine how tiny it must be when we know that a great many of them find room to live on a single mosquito. Now, when the mosquito lights on a person and bites him, these germs often get into the little puncture which the insect makes to draw blood. In this way they get into the blood of the human being, and there they increase in numbers very fast. They poison the blood, the person becomes sick and weak, suffers from headache and other pains, and very often dies at last of malaria. We may learn from these facts how important it is that mosquito nets should be used in this country. Even if a person sleeps upon the floor, he should arrange some sort of protection from the mosquitoes.
