Some harmful effects due to human exposure to ultraviolet rays would be:
A risk of skin cancer for being out in the sun too long.
Also you could get a sunburn. Which is very painful.
One of the most harmful rays {for skin} is UV {Ultra-Violet} rays. That is the only thing that comes to mind when you mention "harmful rays for the human body". Not only can it cause skin cancer, but it can leave your skin burnt red and hurting for days, possibly weeks. Though we need the sun rays, the downfall to getting too much sun is getting skin cancer which is fatal.
UV is not dangerous. UV gives you very important vitamin called as vitamin D. Large amount of UV in tropical sunlight has not created any problems, because of dark color of the skin of the people there. The people from Europe did not get problem for hundreds of centuries, because the amount of UV was too less there. The relocation of people from Europe in USA has exposed them to bright sun light. This situation has created the basic problem. The large scale industrialization has created larger holes in the protective ozone layers. The UV rays with short wave lengths are carcinogenic to the people with fair skin. Such rays can cause cancer of the skin.
An excessive exposure to the ultraviolet (UV) rays of the Sun can cause sunburns. Repeated, long-term excessive exposure to UV is correlated with an increased risk of various kinds of skin diseases and cancers such as melanoma.
However, the lack of sunlight is also associated with diseases, most notably the vitamin deficiency disease "ricketts". Sunlight in moderation is essential for your health and well-being.
Short wave length ultra violets rays are ionising radiations and are very much harmful to your body. They generate free radicals and are potentially carcinogenic. Thanks to your immune system that most of such cancer cells are engulfed by phagocytes. They melanin pigment protects you from such harmful radiations.
It can damage your skin and your eyes, and too much may lead to skin cancer.

Is light energy harmful to human?
Excessive exposure to certain types of light energy, such as ultraviolet (UV) radiation from the sun, can be harmful to human skin and eyes, leading to issues like sunburn, premature aging, and eye damage. It is important to take precautions like wearing sunscreen and sunglasses to protect yourself from the harmful effects of light energy.
What light has a frequency too high for your eyes to see?
Ultraviolet light has a frequency too high for human eyes to see. It is located beyond the violet end of the visible spectrum and can be harmful to the eyes if exposure is prolonged.
Is schist saft for human lives?
Schist itself is not directly harmful to human life. However, prolonged exposure to certain minerals found in schist, such as asbestos, can be harmful to human health. It is important to take precautions when working with schist to minimize exposure to harmful substances.
Are black lights harmful to the human eye?
Black lights emit ultraviolet (UV) radiation which can be harmful to the human eye in high doses. Prolonged exposure to UV radiation from black lights can cause damage to the cornea and lens of the eye. It is recommended to use caution and avoid staring directly into black lights for extended periods of time.
Why do more ultraviolet waves reach earth today?
More ultraviolet waves reach Earth today due to human activities such as industrialization and the thinning of the ozone layer. This allows more UV radiation to penetrate the atmosphere and reach the Earth's surface, leading to increased exposure to harmful UV rays.
What are some benefits on human exposure to ultraviolet rays?
Exposure to ultraviolet rays helps the body produce vitamin D, which is important for bone health and immune function. Controlled exposure can also improve mood and help treat certain skin conditions like psoriasis. However, excessive or prolonged exposure can lead to sunburn, premature aging, and an increased risk of skin cancer.
Is a ultraviolet is part of an human eye?
Ultraviolet, commonly known as UV rays, is a part of the electromagnetic radiations with wavelength in the range 400nm-10nm. It is not a part of the human eye. It is intact considered to be harmful the human eye, skin, etc. More information can be found on the link below.
What is the Effects of harmful substances to human?
Harmful substances can have various effects on the human body, depending on the substance and level of exposure.
