“Tuberculosis is a direct result of over-work, either mental or physical, and rest is largely its cure. This life in the open air is best carried out in a sitting or semi-reclining posture. Every hour of the day in all seasons of the year and in all kinds of weather should thus be spent, together with sleeping in a tent, protected veranda, or in a house with windows wide open. It will be found that the colder the weather, the more marked and permanent the results. One does not need to be uncomfortable; one can be well wrapped with heavy blankets. It is the inhalation of cold air that is so effectual in stimulating appetite, as a general tonic and fever reducer. A consumptive should have for his motto: ‘Every hour in the closed house is an hour lost.’ There is no excuse for losing time.” But it is not for those who are in ill health alone that I would commend out-of-door sleeping. Those who are healthy need to be kept in health, and there is a vim, a vigor, a physical joy, comes from this habit that I would that every child, young man and woman, and adult in the land might enjoy. Here is what one intelligent writer, Mary Heath, has recently said upon this subject, and her words I most heartily indorse: “The success of any scheme for human betterment, morally, mentally, or physically, depends upon securing human co-operation by convincing the intellect of the truth or falsity of any widespread belief. The almost universal notion that night air is dangerous has predisposed, more than any other one cause, to the shutting of every door and window at sunset to keep out malaria.

After false ideas about the harmfulness of fresh air are eradicated, plans should be devised and utilized for arranging outdoor sleeping apartments; plans should also be devised for keeping the body warm in cold weather without an over-amount of bedclothing; and for the health and convenience of the millions of middle class and more or less humble domestic home workers, provisions should be made for doing the housework as much as possible out of doors, away from the kitchen heat and odors of cooking food. Out-of-door recreation for the family should also be provided for. Could all sedentary workers spend the seven to nine hours of sleep in a clean, outdoor atmosphere, many of the evil effects of indoor sedentary work would be neutralized. The shop, office, or factory employe, after sleeping in the pure night air, would awake invigorated for the day’s demands and duties. Beginning the day aright, with a keen normal appetite for healthful food, he would be able to utilize his working energies without either structural damage
