Understand the Effects of UV Rays to Your Skin

 

There are several kinds of UV rays, according to how much energy they have. Higher-energy UV rays are a kind of ionizing radiation. This means they have enough energy to eliminate an electron from (ionize) an atom or molecule. Ionizing radiation can harm the DNA in cells, which can lead to cancer. But even the highest-energy UV rays don’t have sufficient energy to enter deeply into the body, so their main impact is on the skin.

Positive Effects of UV

 

It triggers Vitamin D.

UV from the Sun is required by our bodies to create vitamin D. Vitamin D aids strengthen bones, muscles, and immune system. It may also lessen the risk of cancers, such as colon cancer.

It helps some skin conditions.

UV is used in the remedy of skin conditions such as psoriasis. This is an ailment where the skin emits its cells too fast and develops itchy, flaky patches. UV treatment delays the growth of the skin cells and soothes the symptoms.

It helps some insects’ navigation process.

Many insects use UV lights from astral objects as references for navigating in flight. This is why a light most of the time attracts flying insects by disturbing their navigation process.

It is useful for disinfection and sterilization.

UV can effectively ‘kill’ microorganisms such as germs and bacteria, for example, when hanging clothes, underwear, and towels outside on the clothesline. UV rays infiltrate the cell’s membrane, damaging the DNA, and so stops its capacity to generate. This adverse effect explains why we can use UV antibacterial lamps for disinfection and sterilization to prevent allergens.

Negative Effects of UV

 

It causes skin cancer.

UV is a human environmental carcinogen. It’s the most pre-eminent and universal cancer-causing agent. There is substantial proof that each of the three primary types of skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma) is because of sun exposure. Research shows that 90% of skin cancers are caused by UV radiation.

It causes sunburn.

UV burns the epidermis. Sunburn happens when skin cells are harmed by heat. This damage is caused by the exposure of energy from UV rays. An increase in blood flows to the affected skin in an attempt to heal it, which is why your skin becomes red when you are sunburnt.

It ages the skin.

UV destroys collagen and connective tissue beneath the top layer of the skin. This causes wrinkles, melasma, and loss of skin elasticity. The difference between skin tone, lines, or pigmentation on the underside of a person’s arm and the top side of the same arm shows the effects of sun exposure on the skin.
