One of the useful effects of ultraviolet rays of the sun is in producing Vitamin D. UV rays are needed by the human body or skin to make Vitamin D. Exposure to UV rays also help in terms of skin conditions like psoriasis.
Sunlight can accelerate skin aging due to the harmful effects of ultraviolet (UV) radiation. UV rays can break down collagen and elastin fibers in the skin, leading to wrinkles, sagging, and age spots over time. It is important to protect the skin from sun exposure by wearing sunscreen and protective clothing.
Slightly. UVB rays are blocked unless you are in a tanning bed (made with special glass that allows UVB rays to pass through). UVA rays somewhat get through, which can tan you slightly over a great amount of time (unless you are hypersensitive, then you may get pink after a couple of hours).
Wrinkles occur via two mechanisms:intrinsic aging (aging changes that your skin would undergo without any external influences, like what you would see in sun-protected areas) These changes are seen in both sun-exposed and sun-protected areas of the skin and are due to internal physiologic changes alone. These are regulated by the person's genes and defects in the body's repair systems that come with aging. The skin becomes thinner and more lax, but there are no pigmentation changes or sun damage.Extrinsic or photoaging. These occur on sun-exposed skin and are caused by external factors, such as ultraviolet light damage, pollution and smoking. Sun damage due to ultraviolet light is responsible for almost 80% of the skin changes commonly attributed to the aging process.The most important thing you can do to avoid wrinkles is to avoid exposure to ultraviolet light from the sun and from indoor tanning equipment. Stay out of the sun between the hours of 10 am and 4 pm.Use a broad-spectrum sunscreen with excellent UVB and UVA blocking agents. One of the best UVA blocking agents is avobenzone. Look for this ingredient on the label. Use the sunscreen every day all year long. This will not only prevent wrinkles but will also protect against skin cancer.It is important to remember that sun exposure happens when you are driving, as car windows only block UVB rays but not UVA. UVA is just as damaging but does not burn you as quickly as UVB.The most significant sun damage happens before age 20, so protecting children from sun exposure is extremely important. It does not mean, however, that after age 20 it's OK to get sun exposure, as sun damage is cumulative.
Yes. The closer you are to noon the stronger the sun's rays hitting the earth, so before 10am and after 2pm are safer, but not entirely safe. I try to be inside or in the shade in June, July and August between 10am and about 5pm but I've definitely gotten slight sun burns biking after 5. Remember that at the peak of summer the sun doesn't set until after 9pm, so it can still be pretty high in the sky at 5.
Well this is because when we get older our skin starts stretching when this happens we get spots on us that our body doesn't catch up with its self and they called the spots liver spots then you get theses when your skin starts drying out those spots are brown the skin starts loosening up we bump or self's it can turn your skin red purple and tear the skin.Our skin isn't very strong.
Useful effects of UV are also there. Filters, locks etc use UV.
There is no such thing as sun cancer. Cancer caused by excessive exposure to ultraviolet rays is skin cancer.
UV RAYS!!! The sun is the major natural source of UV Rays. UV Rays are invisable. They are still a form of light rays. UV stands for Ultra Violiet Rays. These (UV) rays cause sunburn and damage the eyes. Overexposure of UV Rays can cause serious skin cancer. UV Rays, however, can have useful effects, too. They can destroy harmful organisms.

Sun Rays ^-^
It absorbs UV rays from the sun. These are fatal rays of the sun.
The sun's rays
Ultraviolet rays.
Ultraviolet rays from the Sun cause sunburns.
Ultraviolet rays cannot be seen or felt. Ever had a sun-burn? I say UV rays can be felt.
they are called UV, or Ultraviolet rays.
