People living in the natural world, a variety of different wavelengths of electromagnetic radiation at any time and dependencies as partners, and continue to function in human body, affect people's health. The effect, is beneficial to human body health side, also have adverse to human body health. Then, the electromagnetic radiation on human health have what effect?

One, the influence of infrared. Infrared energy is smaller electromagnetic wave. It to the human body mainly produce thermal effects, the light can penetrate human skin 3-8CM deep. Infrared ray on human health the main role is to: promote blood circulation and tissue metabolism; infrared has anti-inflammatory, analgesic effect; infrared can cause a person's skin cells to produce pigmentation, prevention of deep tissue of human body overheating; infrared if large dose irradiation can cause the human visual impairment, or even the occurrence of cataract.

Secondly, the effects of visible light. The visible light in the orange light has anti-inflammatory, analgesic effect, and make people excited, nervous reaction acceleration; and blue violet has a sedative effect, the spirit of people in response to reduced.

Thirdly, the effects of ultraviolet radiation. Ultraviolet was one of the larger energy of electromagnetic waves. UV radiation on the human body mainly produces chemical effect, the light can penetrate human skin shallow part, but on human health has important function and influence. The main effect of UV radiation on the human body : the surface of the skin inflammation has anti-inflammatory, analgesic effect; antirachitic effect; sterilization; immune function of health care; the human skin cells to produce pigmentation. Adverse effects are summer sun light in the ultraviolet radiation is strong, can cause human body phototoxic and photoallergic reaction. Phototoxic reaction is in the hot sun illumination 2-3 an hour later, the human forearm, back local flushing, bean rash, which can damage human health. Some people may also lead to skin cancer in adults. If the eyes of the people heavily irradiated, can cause eye face arthritis, conjunctivitis, corneal ulcer. Therefore, in the summer noon when most intense ultraviolet radiation, should minimize outdoor activities. Noon goes out work must do well labor protection, to prevent UV damage.

Therefore, understanding of the electromagnetic wave radiation on human health effects, take active and effective protection measures, can draw on the advantages and avoid disadvantages, ensure the health of human body.
