Harm of indoor lighting
The long-term use of indoor lighting has invisibly disrupted the circadian circadian clock, which has changed the inherent physiological patterns of the human body. This will not only advance the mature age of human beings, but also make people's circadian rhythm disorder, and then there will be palpitations, chest tightness, and mental wilting. Other researchers believe that the intense light emitted by indoor lighting can cause genetic degeneration of a large number of cells in the human body, causing abnormal cells to increase and normal cells to die.
Working under the light for a long time will not only cause eye fatigue, but also reduce the body's ability to absorb calcium. Because there is a big difference in the nature and intensity of light and sunlight. Natural light contains many colors and wavelengths, while indoor lighting is only yellow, orange, red, and lacks the beneficial ultraviolet light in the sun, so the absorption of calcium is greatly reduced. In addition, the light emitted by the fluorescent lamp has blue and invisible ultraviolet rays, which are likely to cause cancer of the human body after being excessively absorbed by the human body.
To this end, experts suggest that it is best to use natural light during the day, always open the window and let the sun enter the room; those who work at the office desk all day should pay attention to taking time to outdoor activities to avoid the infection of modern lighting diseases.
When you must use indoor lighting equipment, you should grasp the following five principles: use a wide range of lighting, such as when reading a book on a desk, the light should shine on the entire table; use uniform lighting, which refers to the place where the lighting, each part The illumination should be consistent; maintain stable illumination, the light source should not be bright or blinking when it is dark; maintain sufficient illumination, there is no uniform standard, generally depending on the nature of the work, that is, the finer the work, the required The higher the illumination, the last point, be careful not to let the light shine directly into the eyes.
