What is the effect of ultraviolet and infrared?
Infrared radiation produces erythema, which is probably a thermal effect. In this article we reviewed the available literature on the effects of ultraviolet radiation, visible light, and infrared radiation on the skin in regards to erythema and pigmentation.
What are the effects of infrared radiation?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
What are the effects of infrared radiation on human skin?
Recent work demonstrates that IR and heat exposure each induces cutaneous angiogenesis and inflammatory cellular infiltration, disrupts the dermal extracellular matrix by inducing matrix metalloproteinases, and alters dermal structural proteins, thereby adding to premature skin aging.
What are the dangers of ultraviolet radiation?
UV radiation causes both short and long-term eye problems, including: excessive blinking, swelling and difficulty looking at strong light. It can also cause cancers and acute photo keratopathy, which is sunburn of the cornea.
What are the harmful effects of ultraviolet light?
UV Light and Health Effects Biological Effect of UV Light. UVC Effect on Skin. Personal Protective Equipment (PPE) UV radiation is easily absorbed by clothing, plastic or glass. Safety Design/Control/Monitoring/Maintenance. Response to UV Exposure.
Why can too much ultraviolet radiation be harmful?
One common negative effect of ultraviolet radiation is aging. Too much exposure to the sun is known to be a great factor in the skin-aging process. Normally, the collagen and connective tissues present in the skin make it soft and elastic. But with too much ultraviolet radiation, these components get damaged causing harm to the skin.
How does ultraviolet radiation harm living things?
UV radiation has been shown to be harmful to living organisms, damaging DNA, proteins, lipids and membranes. Plants, which use sunlight for photosynthesis and are unable to avoid exposure to enhanced levels of UV radiation, are at risk. Thus, mechanisms by which plants may protect themselves from UV radiation are of particular interest.
