Everyone loves windows. Research suggests that exposure to sunlight has a positive effect on peoples’ physical and mental well being. Lack of sunlight can also contribute to seasonal effective disorder, a mood disorder characterized by a lack of energy and mild depression. While windows are important, it is sometimes necessary to cover them with blinds. Blinds can block out sunlight, allowing us to sleep through day light hours and giving us privacy.
The earliest windows were just holes cut into walls. These windows were covered with animal hides, cloth, or wood to keep out the sunlight. These are the earliest examples of what would eventually become blinds. Today, blinds are much more sophisticated, offering more control, greater safety, easier installation, better blockage of sunlight and more.
