How do sunburns happen




















These include premature aging of skin photoaging , precancerous skin lesions and skin cancer. Sun exposure and repeated sunburns accelerate the skin's aging process, making you look older than you are. Skin changes caused by UV light are called photoaging. The results of photoaging include:. Precancerous skin lesions appear as rough, scaly patches in areas that have been damaged by the sun.

They're usually found on the sun-exposed areas of the head, face, neck and hands of light-skinned people. These patches can evolve into skin cancer. Excessive sun exposure, even without sunburn, increases your risk of skin cancer, such as melanoma. It can damage the DNA of skin cells. Sunburns in childhood and adolescence may increase your risk of developing melanoma later in life.

Skin cancer develops mainly on areas of the body most exposed to sunlight, including the scalp, face, lips, ears, neck, chest, arms, hands, legs and back.

Some types of skin cancer appear as a small growth or a sore that bleeds easily, crusts over, heals and then reopens. With melanoma, an existing mole may change, or a new, suspicious-looking mole may develop. A type of melanoma called lentigo maligna develops in areas of long-term sun exposure.

It starts as a tan flat spot that slowly darkens and enlarges. See your doctor if you notice a new skin growth, a bothersome change in your skin, a change in the appearance or texture of a mole, or a sore that doesn't heal.

The sun can also burn your eyes. Too much UV light damages the retina, lens or cornea. Sun damage to the lens can lead to clouding of the lens cataracts. Sunburned eyes may feel painful or gritty.

Sunburn of the cornea is also called snow blindness. Use these methods to prevent sunburn, even on cool, cloudy or hazy days. And be extra careful around water, snow and sand because they reflect the sun's rays.

In addition, UV light is more intense at high altitudes. Use sunscreen frequently and generously. About 15 to 30 minutes before going outdoors, apply sunscreen generously on skin that won't be protected by clothing. Put on more sunscreen every 2 hours and after swimming or sweating.

If you're also using insect repellent, apply the sunscreen first. The American Academy of Dermatology does not recommend products that combine an insect repellent with a sunscreen.

The Food and Drug Administration requires all sunscreen to retain its original strength for at least three years. Check the sunscreen labels for directions on storing and expiration dates.

Throw away sunscreen if it's expired or more than three years old. Protect babies and toddlers. The American Academy of Pediatrics recommends using other forms of sun protection, such as shade or clothing, for babies under 6 months. When that's not possible, apply sunscreen with at least 15 SPF to the face and back of the hands. The American Academy of Dermatology recommends not using sunscreen on children under 6 months. Keep them cool, hydrated and out of direct sunlight. If sun protective clothing and shade aren't available, consider using sunscreen on babies and toddlers.

Once inflammation subsides, the lower layer of skin cells begins to grow quickly to replace the dead cells. Post-sunburn peeling is large sheets of dead cells being shed from the upper layer of the skin to make way for this new growth.

DNA damage also causes the cells in the upper layer of skin to signal the cells that produce melanin the pigment that gives our hair and skin its colour to get to work. This is what provides the tan that can come after the redness has faded. The melanin settles over the skin cells to shield them from future UV exposure.

In the meantime, you can relieve the discomfort by staying out of the sun, drinking plenty of water, applying a cool compress, and taking over-the-counter medications such as paracetamol.
