But it may cause fatigue or eyestrain and lead to dizziness, headaches, or sleepiness. Regardless of where lighting is used, people depend on it for general seeing and safety, for specific activities, and for decoration. In the home, electric lamps and lighting fixtures provide light and safety for people walking from room to room or up and down stairs. Every room and passageway needs at least some general lighting so that things can be seen clearly enough to avoid accidents. Each area should have a light that can be turned on before entering.
Many activities require extra lighting in addition to general lighting.
Bathrooms, for example, have special lighting that people use when putting on makeup or shaving. Bedrooms and living rooms have additional lighting for such activities as reading, studying, and sewing. Interior designers use lighting to create various moods and to bring out the colors of walls and fabrics in a home. Cool white fluorescent lamps bring out blues and greens. Many people arrange spotlights or tinted lights to create interesting shadows.
