PROTECTING FROM THE SUN

PROTECTING FROM THE SUN

The rising temperature and the rising insurgency, these days, are like peas in a pod. What’s the matter is the Sun getting hotter or is it the Climate? People these days have come across much hotter roads and the Sun rays. However one needs to be protected from the Sun and get known about the same.

E

xposure to sunlight and to the ultraviolet rays has for many years been considered to be a health measure of great importance. Long continued exposure to sunlight has been shown to increase materially cancer of the skin in those exposed to the ultraviolet rays of the spectrum. The outdoor workers are much more frequently the sufferers from superficial skin cancer than indoor workers. The corollary is obvious; too much sunlight may be harmful to the white individual. Negroes are apparently protected by the pigment in their epidermis against the carcinogenic effect of the sun's rays.

The superficial complexion especially of human is determined by pigment melanin. The shade of melanin depends upon racial origin, the quantity of which is greater in Negroes and other dark races. A suntan depends upon the exposure to the sunlight causing cumulative deposition of melanin in outer layers of epidermis. However melanin crop is due to the pituitary and the sun rays exposure to hotter climate. Consequently people living near the equator have darker complexion than those living in the temperate region. In human the graying/whitening of the hairs is caused by the loss of the melanin.

Scientists believe that the sun’s ultraviolet rays damage the DNA of the skin cells, eventually turning them cancerous. Skin cancer develops most commonly on sun-exposed areas, such as the face, hands, arms, and legs. People who have light skin that sunburns easily are at higher risk of skin cancer, as are people who have a history of significant sun exposure, particularly those who regularly sunbathe or those who work outside without protective clothing, such as lifeguards. However, several decades may elapse between sun exposure and the development of skin cancer—someone who was a lifeguard at age 20 may not develop skin cancer until age 50, for example. Moles or other darkly pigmented areas of the skin that change appearance by enlarging, bleeding, or developing irregular borders or coloring may be a sign of cancer. Doctors recommend that people at risk for skin cancer regularly self-examine their body for any skin changes. Whatever their skin tone, people can reduce their risk of developing skin cancer by wearing clothing that covers the body and a hat that shields the face when in the sun and by using a sunscreen with a sun protection factor (SPF) of 15 or greater.

White dressing is only the solution to reflect maximum sun rays. Pertaining to the fact that canopy or the parasol (black not recommended) become alternatives to those for brief wears. Sunbathing though the cause of carcinoma, regular bathing is ablution to sun rays adherement or stratum cornium shed. Photo chromatic lens or   gogs/specs shield eyes from optic spectra and to absorb UV A and UV B. The body temperature rise rapidly with perspiration and the polyuria are troubleshooting. Intake of excessive fluids may control the perspiration and satisfy appetite.

Greater is the exposure as aforesaid greater is the prospect of carcinoma and darker complexion. Enhanced indoor resting, though not always possible, makes you welcome.  And so you better ensure you are free from the effect and the burn.
