The four ways that the body can be harmed by over-exposure to ultraviolet light are wrinkles, skin cancer, cataracts, and skin burns.
Ultraviolet (UV) light treatment is used primarily in cases of severe psoriasis that have not responded to other medications or in cases affecting large portions of the body.
The Ultraviolet light (UV) releases happy hormones into the body, so when you wake up and the Ultraviolet light shines on you, you feel happy. Just like if it was a sunny day and you feel excited, it has the same effect.
The difference between ultraviolet radiation and ultrasound is how they react when inside the body. Ultraviolet radiation attacks the cells and destroys cells that are harmful to the body. Ultrasound is merely a viewing device. Ultrasound is used to detect abnormalities in the body.
Any part of the body where skin is exposed will capture ultraviolet and infrared energy
Many parts of the EM spectrum are harmful. Ultraviolet can cause skin cancer, microwaves can cause heating of body mass, X-rays and gamma rays cause ionisation of body mass and too much exposure will cause cancer or acute damage to the blood cells which will cause rapid death. X-rays are a vital medical tool, but must be carefully used to avoid damage. If you have had hospital X-ray treatment you will have seen that the radiographers go behind a screen during exposure, because they are doing it all day and woulg get too much exposure otherwise
vitamin D
Ultraviolet is needed for healthy skin growth. It is also needed to produce Vitamin d
No. Body color is due to the pigment melanin. The more melanin in your skin cells, the darker your skin. Melanin production is also stimulated by exposure to ultraviolet light, which is what causes skin to tan.
Vitamin D. It is made from cholesterol in response to extended exposure to sunlight.

Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
That would depend on its intensity during the brief exposure.
Vitamin D
In industrial applications this is known as 'sanitizing', 'disinfecting' or 'sterilizing' via chemical treatment, heating, or exposure to ultraviolet light. In biology, the removal process is the body's immune system releasing T-cells or white blood cells to attack and kill the invading micro-organisms.
Ultraviolet (UV) light causes some body fluids, such as urine and semen, to fluoresce, making them visible to the naked eye.
