Natural sunlight is good for us. Sunlight is the best source of vitamin D. It improves our immune system and helps to regulate many of our bodily processes. It increases our sense of well-being, alertness, ability to learn, attitude, happiness, and productivity. People function better in a natural environment.
Due to our schedules, work, and family commitments – we just can’t enjoy the sunlight as much as we could or should. Until now, man-made methods of normal lighting have been less than ideal, sometimes even detrimental.
