Light is the basic source of energy, or life force, for living systems. Whether by receiving nourishment in the form of vitamin D through outdoor contact, or by eating fresh and nutrient-rich foods that have a closer relationship to the sun, or even through the energy in our homes that comes from the sun in some form, we all orient our lives to this relationship in some way or another. The more direct our connection to sunlight, the more energy, growth, and satisfaction we enjoy in our daily lives.
