Dehydration and sunburn -
original electrolyte blend for rapid hydration. The warm weather, beach trips, and the longer days are just some of the great joys of the season. But one thing that unfortunately comes with the summer season is sunburns.
Sunburns are caused by prolonged exposure to ultraviolet light, regardless of whether it is natural or artificial. There are three types of Ultraviolet light: A, B, and C.
Ultraviolet A is a form of solar radiation that is typically associated with the aging of the skin and Ultraviolet B is what we associate with sunburns. While Ultraviolet C is mostly absorbed by the atmosphere, both ultraviolet A and B are associated with the development of skin cancer.
The good news is that our skin has a way to protect the body from the ultraviolet light—melanin. This works to prevent sunburns and skin damage. So, eventually, exposure to ultraviolet light will cause your skin to burn. But other symptoms associated with sunburns are itching, swelling, fluid-filled blisters, headaches, fevers, nausea, and fatigue.
When your skin gets burned, it is actually a radiation burn caused by the ultraviolet rays of sunshine that damage the DNA located in your epidermis. The photons or particles that transmit light, from ultraviolet A rays can interact with the skin and damage the proteins, membranes, and DNA.
Conversely, photons from ultraviolet B rays are absorbed by the DNA and this extra energy can lead to incorrectly linking DNA. These rays of sunshine stop accurate DNA replication and as a result many mistakes are made and cells are responsible for trying to fix them. Once DNA damage is detected in the top skin layer cells, they produce molecules that attract immune cells.
This leads to the blood vessels in the skin to leak into spaces between cells and other structures. This extra fluid and the resulting swelling is what causes the red and painful skin that is hot to the touch.
This process of immune cell invasion starts even when you are still in the sun, but it increases an hour after you leave the rays developing redness and pain as the process peaks about hours later. Some of these immune cells clean up after the self-destructing skin cells while other immune cells release chemicals that can cause more damage to the weakened skin cells.
These actions can initiate a sort of allergic reaction that makes you feel itchy. When the inflammation starts to decline, the new cells are grown quickly to replace the dead ones.
This is what causes post-sunburn peeling. The old cells are quickly being shed to make room for the new ones. This is why you might get a tan after the sunburn has healed.
The melanin shields the skin from future exposure. However, this tan is only as effective as SPF 2 sunscreen, and should not serve as a replacement for any future protection. Unfortunately, after the sunburn, all you can do is wait for the skin to heal. However, you can manage the symptoms by taking over-the-counter medications, applying home remedies, and drinking plenty of water.
Preventing sunburn year-round by wearing sunscreen or using other skin-protection habits is important for everyone. It is especially important when you're outdoors, even on cool or cloudy days.
Any exposed part of the body — including the earlobes, scalp and lips — can burn. Even covered areas can burn if, for example, clothing has a loose weave that allows ultraviolet UV light through. The eyes, which are extremely sensitive to the sun's UV light, also can burn. Within a few days, the body may start to heal itself by peeling the damaged skin's top layer.
A bad sunburn may take several days to heal. Any lingering changes in skin color usually go away with time. Sunburn is caused by too much exposure to ultraviolet UV light. UV light may be from the sun or artificial sources, such as sunlamps and tanning beds.
UVA is the wavelength of light that can penetrate to the deep layers of skin and lead to skin damage over time. UVB is the wavelength of light that penetrates the skin more superficially and causes sunburn. The UV light damages skin cells.
The immune system reacts by increasing blood flow to the affected areas, which causes the inflamed skin erythema known as sunburn. You can get sunburn on cool or cloudy days.
Surfaces such as snow, sand and water can reflect UV rays and burn skin too. Intense, repeated sun exposure that results in sunburn increases your risk of other skin damage and certain diseases.
These include premature aging of skin photoaging , precancerous skin lesions and skin cancer. Sun exposure and repeated sunburns speed the skin's aging process. Skin changes caused by UV light are called photoaging.
The results of photoaging include:. Precancerous skin lesions are rough, scaly patches in areas that have been damaged by the sun. They're often found on the sun-exposed areas of the head, face, neck and hands of people whose skin burns easily in the sun.
These patches can evolve into skin cancer. They're also called actinic keratoses ak-TIN-ik ker-uh-TOE-seez and solar keratoses. 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 the risk of 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 grow. Too much UV light damages the 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.
This type of damage might be caused by the sun, welding, tanning lamps and broken mercury vapor lamps. Use these methods to prevent sunburn, even on cool, cloudy or hazy days. Be extra careful around water, snow, concrete and sand because they reflect the sun's rays. In addition, UV light is more intense at high altitudes.
Use sunscreen often and generously. Use water-resistant, broad-spectrum lip balm and sunscreen with an SPF of at least 30, even on cloudy days. Broad-spectrum products offer protection against ultraviolet A UVA and ultraviolet B UVB rays. About 30 minutes before going outdoors, generously apply your sunscreen to clean, dry skin.
Use at least 2 tablespoons of sunscreen, or 1 ounce, to cover all surfaces of the exposed skin, except the eyelids. If you're using spray sunscreen, spray it into your hands and then rub it into the skin. This helps avoid inhaling the product. Don't use a spray product while smoking or near an open flame.
If you're using a product that contains physical blockers titanium oxide, zinc oxide , apply it over any other products you're wearing — except insect repellent.
Insect repellent goes on last. Physical blockers provide the most effective protection for sensitive skin. Reapply sunscreen every two hours — or more often if you're swimming or perspiring.
If you're wearing makeup and want to reapply your sunscreen without redoing your whole face, one option is to use an SPF powder over makeup. The Food and Drug Administration FDA requires all sunscreen to retain its original strength for at least three years.
Check 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.
Protect babies and toddlers from sunburn with brimmed hats and lightweight clothing that covers the arms and legs. Keep them cool, hydrated and out of direct sunlight.
When that's not possible, the American Academy of Pediatrics suggests applying sunscreen with an SPF of at least 15 to the face and back of the hands. The American Academy of Dermatology and the FDA don't suggest sunscreen for children under 6 months. If sun-protective clothing and shade aren't available, sunscreens containing zinc oxide or titanium dioxide are the next best choice.
Ian Roth: You're heading to the pool or beach, and you stop to pick up some sunscreen. But knowing what is the best SPF is tough when you have no idea what SPF actually means. Dawn Davis, M. It is simply a ratio of the number of minutes that you can stay outside with the product on before getting minimal redness to the skin.
Ian Roth: And Dr. Dawn Davis, a Mayo Clinic dermatologist, says preventing that painful redness is one of the biggest factors in preventing skin cancer. So how do sunscreen brands calculate an SPF? Davis: So if you stand outside in a particular location and you're testing the sunscreen and it takes you 10 minutes to develop redness to the skin without the product on, but then you apply the product on a different area of skin and it takes 50 minutes for the skin to show redness, then that is an SPF factor of 50 over 10, which equals 5.
Ian Roth: Dr. Davis recommends a minimum of SPF 30, which theoretically means you could stay protected from UV rays 30 times longer than without sunscreen.
