Some make themselves sick by overwork. For these, rest, freedom from care, and a spare diet, are essential to restoration of health. To those who are brain weary and nervous because of continual labor and close confinement, a visit to the country, where they can live a simple, carefree life, coming in close contact with the things of nature, will be most helpful. Roaming through the fields and the woods, picking the flowers, listening to the songs of the birds, will do far more that any other agency toward their recovery.

Rest, spare diets, and simple living in natural environments are essential for restoring health in those exhausted by overwork. The text recommends specific lifestyle prescriptions—nature exposure, rest, and simple diets—for recovery from overwork and nervous exhaustion.
