Question

Which of the following benefits is derived from UV light?

1) Kills bacteria and viruses
2) Promotes vitamin D synthesis
3) Reduces inflammation
4) All of the above

Answer 1

UV light has multiple benefits, including killing bacteria and viruses, promoting vitamin D synthesis, and reducing inflammation. It plays an essential role in health by enabling vitamin D production and has applications in medicine, such as in phototherapy for treating infantile jaundice.

Step-by-step explanation:

The benefits derived from UV light include the ability to kill bacteria and viruses, the promotion of vitamin D synthesis in the skin, and the reduction of inflammation. UV light, particularly UV-B radiation from sunlight, plays an essential role in producing vitamin D, which is crucial for maintaining healthy bones and may protect against certain cancers and osteoporosis.

In medical applications, UV light is used in phototherapy treatments for conditions such as infantile jaundice, where it helps prevent the buildup of bilirubin in the blood. Moreover, UV light has sterilizing capabilities that make it effective against microbes.
