What is sun protection?

Sun protection is simply guarding a body from the adverse effects of sunlight. Aside from the hazards of heat, the sun poses the danger of sunburn, which can permanently damage the skin and cause skin cancer, precancerous changes in the skin, as well as premature wrinkling and signs of aging. Exposure to ultraviolet rays from the sun is a known risk factor for the development of both melanoma and non-melanoma skin cancers.

How is sunburn best prevented?
The best ways to avoid sunburn are to
limit time in the sun, especially between peak sunlight hours of 10 a.m. and 3 p.m.;
wear protective clothing, including
a broad-brimmed hat,
a shirt with sleeves that cover the arms, and
a long skirt or pants with long legs; and
use a protective sunscreen to minimize the penetration of the sun's ultraviolet (UV) rays

What is sunscreen?

Sunscreen is any substance or material that protects the skin from UV radiation. Sunscreens are available in the forms of topical lotion, cream, ointment, gel, or spray that can be applied to the skin; a salve or stick that can be applied to the lips, nose, and eyelids; a moistener in towelettes that can be rubbed against the skin; sunglasses that protect the eyes; certain types of sun-protection clothing; and film screen that can be affixed to the windows of a car, room, or office.

Taary shor karty han

Sumandar pur sukoon hai

par kinary shor karty hain,

mery atraf bus rangeen nazary

shoor karty hain,

aur ab to chandni raatein

mujhy achi nahi lagteen,

sukoon se so nahi sakti

k taary shor kartay hain,

main jab khamosh rehti honto

sub khamosh rehty hain,

boht muddat hoi jab

tummery kochay se guzray thay,

par qadmon k nishan ab tk

tumhary shor karty hain...
