“Light is as indispensable to life as air itself. Hence it is that Hell is represented as completely dark. Where light cannot penetrate, the air can never be pure. Those who thus deprive themselves of air and light are always weak and haggard. Now-a-days, there are many doctors in Europe who cure their patients by means of air-bath and sun-bath alone. Thousands of diseased persons have been cured by mere exposure to the air and to the sunlight. Dwellers in towns are, as a rule, more delicate than those in the country, for they get less air and light than the latter.”

About this quote
Sunlight and moving air do quiet work on the body that stale, shut-in rooms undo. People who close themselves off from both tend to weaken over time. It costs nothing to open a window or step outside, yet that simple exposure supports the body in ways no dim, airless room ever can.
When to use it
- Someone recovering from illness sets a chair by an open window each morning to sit in the sun.
- An office worker takes a short daylight walk instead of eating lunch at a windowless desk.
- A family airs out and sunlights the bedrooms weekly instead of keeping the curtains drawn all day.
