Effects on the mind and body
Colored light can also have an effect of a person. Warm white lights are welcoming and uplifting. Cool colored lights (blue, green, purple) produce a calm, restful environment, but can become "unfriendly, cold, and depressing" after prolonged exposure. Bright colors (red, orange, yellow) produce eyestrain, which leads to a feeling of physical exhaustion as the mind struggles with coping with the intensity ("Interiors: an Introduction").
Seasonal Affective Disorder (SAD)
- Window treatments, such as shades or blinds, block the light that comes from the sun.
To reduce glare from artificial lighting, a person can lower their wattage usage, use a cool-beam lamp (type of light that is designed to redirect its heat away from the light beam), adjust the direction of the lighting source, or use baffles (a device such as a board or grid that deflects light, either to direct it or to prevent glare).
