Overexposure to UV radiation from sun and artificial sources raises public health concern

Agency News

Kolkata, Jan 19: Overexposure to ultraviolet (UV) radiation from the sun and artificial sources is of considerable public health concern.

It plays an important role in the development of skin cancer and eye damage (particularly cataracts), and suppresses the immune system.

Children are particularly at risk as (i) sun exposure during childhood and adolescence appears to set the stage for the development of both melanoma and non-melanoma skin cancers in later life, (ii) a significant part of a person’s lifetime exposure occurs before age 18, and (iii) children have more time to develop diseases with long latency, more years of life to be lost and more suffering to be endured as a result of impaired health.

The sun emits light, warmth, and ultraviolet (UV) radiation. It is a vital source of energy for all life on Earth, and without the sun, life could not be sustained.

Exposure to UV radiation also enables the human body to produce vitamin D, which plays a crucial role in skeletal development, immune function, and blood cell formation.

However, UV radiation is also of considerable public health concern. In the short term, overexposure to UV radiation causes tanning, sunburn, pain, and in severe cases, blistering of the skin. In the long term,UV radiation exposure accelerates skin ageing, and can lead to skin cancer and even death.

Sun exposure can also cause damage to the eyes, such as contributing to the development of cataracts. A further reason for concern is that UV radiation suppresses immune function, which may compromise the body’s ability to resist disease. (UNI)
