Sun Light Jr. For More Therapeutic Aids. For More Travel Aids. The life on our planet is dependent on the sun.
Sunlight is our natural cue for wakefulness and sleepiness.
Unfortunately, our modern lives don't always allow us to live in perfect harmony with the rising and setting of the sun. Most of us spend almost all of our time indoors. Our careers and other responsibilities often require us to wake before dawn, stay awake long after night has fallen, and spend much of the intervening time in a constant state of stress. When we do get to relax, it is often in the evenings or only on weekends. The result of all of this is that we spend very little of our time outside, enjoying fresh air and sunny weather.
