  Sunburn is an acute inflammatory skin reaction occurring due to extended exposure to ultraviolet (UV) rays from the sun or artificial sources such as tanning beds. […] The severity of sunburn depends primarily on the duration and intensity of exposure to UV rays. Overall, the number of sunburns experienced in individuals correlates with an increased risk of skin cancer. […] Sunburn occurs when the skin is exposed to prolonged UV radiation from the sun or artificial sources. […] The risk of sunburn is elevated by the usage of certain medications, including thiazide diuretics, sulfonamides, fluoroquinolones, nonsteroidal anti-inflammatory drugs (NSAIDs), retinoids, tetracyclines antibiotics such as doxycycline, and St John’s wort, among other photosensitizing medications. […] Understanding environmental factors contributing to sunburn risk is crucial for adequate sun protection and prevention.

• #4 What happens to your skin when you get sunburnt? | Cancer Council

  https://www.cancer.org.au/blog/what-happens-to-your-skin-when-you-get-sunburnt

  Sunburn is a radiation burn, caused when the ultraviolet (UV) rays of sunlight damage DNA in the upper layer of skin cells. […] The particles that transmit light (photons) from UVA rays interact with the skin and this damages the skin’s proteins and membranes, as well as DNA. […] Photons from UVB rays are absorbed by DNA itself, and the extra energy can cause some of the DNA to link up incorrectly. […] Immune cell invasion begins while you’re still sitting on the beach, but increases about an hour after you come in from the sun. […] Some of the immune cells start cleaning up skin cells in self-destruct mode, while others release chemicals that further damage weakened cells. […] Within several hours, blisters form where whole layers of keratinocytes have been killed. […] 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. […] The melanin settles over the skin cells to shield them from future UV exposure.

  Sunburn is caused by excessive exposure of the skin to UVR. The UV spectrum can be divided into the following segments: Ultraviolet A (UVA)-I, 340-400 nm; UVA-II, 320-340 nm; Ultraviolet B (UVB), 290-320 nm; Ultraviolet C (UVC), 200-290 nm. […] Shorter-wavelength UVB rays are much more effective at inducing erythema than UVA rays are and thus are the principal cause of sunburn. […] The minimal single dose of UVR (energy per unit area) required to produce erythema after 24 hours at an exposed site is known as the minimal erythema dose (MED). This dose varies according to skin type. […] Multiple factors influence UVR-induced erythema, including the following: Wavelength – UVB is more erythemogenic than UVA; Skin type/pigmentation – Compared with patients who have type I-II skin, patients who have type IV-V skin require three to five times more UVR exposure to cause erythema; Hydration – UVR causes erythema more effectively in moist skin than in dry skin; Environmental reflection – Radiation is 80% reflected by snow and ice but only 15% reflected by sand; Ozone coverage – Increased levels of ozone filter out more UVR; Altitude – Thinner atmosphere at higher altitudes absorbs less UVR; Latitude – Exposure is greater nearer the equator; Time of day – UVR exposure is greatest from 10:00 AM to 4:00 PM, when the sun is highest in the sky; Season – In locations outside the tropics, UVR is much greater in summer than in winter; Cloud cover – Light clouds attenuate UVR by 10%, which may not be enough to protect from sunburn.

  Sunburn occurs when the skin is overexposed to ultraviolet (UV) radiation from the sun or even from artificial sources such as tanning beds. UV radiation damages the DNA in skin cells, leading to inflammation and reddening of the skin. […] The sun emits various types of radiation, including invisible UV rays. These come in two main categories: […] UVA Rays: These rays penetrate deep into the skin’s dermis layer, contributing to premature ageing and wrinkles. They also play a role in sunburn, though to a lesser extent than UVB rays. […] UVB Rays: These shorter-wavelength rays are the main culprit behind sunburn. They damage the DNA in the skin’s outer layer (epidermis), triggering the inflammatory response that leads to sunburn symptoms. […] The amount of time your skin is exposed to UV rays directly affects the severity of sunburn. The longer you’re in the sun, the greater the risk of sunburn.

  Spending enough time in the sun without adequate protection can leave us looking and presumably feeling like a lobster ready for the plate. […] The conventional explanation for the skin’s painful inflammation response involves a cascade of effects triggered by breaks in the tissue’s DNA. […] It now seems we might have had that key detail incorrect all along. According to a new study involving mice and human skin cells, the first moments of sunburn are a little different from what anybody expected. […] „Sunburn damages the DNA, leading to cell death and inflammation. So the textbooks say,” says Anna Constance Vind, a molecular biologist from the University of Copenhagen who led an investigation that challenges what we thought we knew about sun damage. […] „But in this study we were surprised to learn that this is a result of damage to the RNA, not the DNA that causes the acute effects of sunburn.”

  The term sunburn is something of a misnomer. Unlike low-level thermal burns, which result from heat making a mess of your body’s proteins, sunburn damage is caused by prolonged doses of shorter-wavelength 'B’ type ultraviolet radiation. […] Regardless of how the damage is caused, the result is the same: a variety of cellular stresses alert the immune system to a threat, setting off a domino effect of chemical sirens that widen some blood vessels, restrict others, and elevate sensitivity to pain. […] „DNA damage is serious as the mutations will get passed down to progenies of the cells, RNA damage happens all the time and does not cause permanent mutations,” says Vind. […] „Therefore, we used to believe that the RNA is less important, as long as the DNA is intact. But in fact, damages to the RNA are the first to trigger a response to UV radiation.”

[…] Sunburn results when the amount of exposure to the sun or other ultraviolet light source exceeds the ability of melanin to protect the skin. Melanin is the skin’s protective coloring (pigment). Sunburn in a very light-skinned person may occur in less than 15 minutes of midday sun exposure, while a dark-skinned person may tolerate the same exposure for hours. […] Skin cancer usually appears in adulthood. But it is caused by sun exposure and sunburns that began as early as childhood. […] Factors that make sunburn more likely: Infants and children are very sensitive to the burning effects of the sun. People with fair skin are more likely to get sunburn

  Sunburn is a visible reaction of the skin’s exposure to ultraviolet (UV) radiation, the invisible rays that are part of sunlight. […] Excessive and/or multiple sunburns cause premature aging of the skin and lead to skin cancer. Skin cancer is the most common type of cancer in the US and exposure to the sun is the leading cause of skin cancer. […] Overexposure to sunlight before age 18 is most damaging to the skin. […] Protection from the sun should start at birth and continue throughout your child’s life. It is estimated that 60 to 80 percent of total lifetime sun exposure occurs in the first 18 years of life. […] Sunscreens protect the skin against sunburns and play an important role in blocking the penetration of ultraviolet (UV) radiation. However, no sunscreen blocks UV radiation 100 percent. […] Use of a sunscreen with SPF of 20 to 30 offers substantial protection from sunburn and prevents tanning. High SPF sunscreens protect from burning for longer periods of time than do sunscreens with lower a SPF.

  Skin type determines the ease of sunburn. People with lighter skin tones and limited capacity to develop a tan after UV radiation exposure have a greater risk of sunburn. […] Certain genetic conditions, for example, xeroderma pigmentosum, increase a person’s susceptibility to sunburn and subsequent skin cancers. […] The risk of sunburn can be increased by pharmaceutical products that sensitize users to UV radiation. […] The UV Index indicates the risk of sunburn at a given time and location. […] In recent decades, the incidence and severity of sunburn have increased worldwide, partly because of chemical damage to the atmosphere’s ozone layer.

  https://patient.info/doctor/sunburn

  Sunburn is a common, acute inflammatory response of skin to exposure to ultraviolet radiation (UVR). […] UVR causes vasodilation and release of mast cell mediators, leading to an inflammatory response. […] Sunburn is usually a superficial epidermal burn but may be partial thickness in severe cases. […] The cause is usually clear from the history, but consider: Photosensitivity. […] Xeroderma pigmentosum and related conditions (if there is sunburn with minimal exposure). […] Sunburn is better prevented than treated. Sun protection is the best defence against sunburn and other damaging effects of UVR.

  Sunburn is caused by excessive exposure of the skin to UVR. The UV spectrum can be divided into the following segments: Ultraviolet A (UVA)-I, 340-400 nm; UVA-II, 320-340 nm; Ultraviolet B (UVB), 290-320 nm; Ultraviolet C (UVC), 200-290 nm. […] Shorter-wavelength UVB rays are much more effective at inducing erythema than UVA rays are and thus are the principal cause of sunburn. […] The minimal single dose of UVR (energy per unit area) required to produce erythema after 24 hours at an exposed site is known as the minimal erythema dose (MED). This dose varies according to skin type. […] Multiple factors influence UVR-induced erythema, including the following: Wavelength – UVB is more erythemogenic than UVA; Skin type/pigmentation – Compared with patients who have type I-II skin, patients who have type IV-V skin require three to five times more UVR exposure to cause erythema; Hydration – UVR causes erythema more effectively in moist skin than in dry skin; Environmental reflection – Radiation is 80% reflected by snow and ice but only 15% reflected by sand; Ozone coverage – Increased levels of ozone filter out more UVR; Altitude – Thinner atmosphere at higher altitudes absorbs less UVR; Latitude – Exposure is greater nearer the equator; Time of day – UVR exposure is greatest from 10:00 AM to 4:00 PM, when the sun is highest in the sky; Season – In locations outside the tropics, UVR is much greater in summer than in winter; Cloud cover – Light clouds attenuate UVR by 10%, which may not be enough to protect from sunburn.

  Sunburn happens when you are exposed to ultraviolet (UV) radiation from the sun. […] Sunlight contains ultraviolet (UV) radiation. Too much UV radiation causes sunburn. […] UV radiation causes your skin to make more of a pigment called melanin to protect itself. This causes the skin to change colour. When you are exposed to more UV radiation than your skins melanin can cope with, you get a sunburn. […] You can be exposed to UV radiation from the sun and also from a solarium (tanning bed). […] It is also possible to get sunburn while swimming or in the snow. This is usually caused by the sunlight reflecting off the snow, ice or water and burning your skin. […] You are most at risk of sunburn if you have fair skin. But anyone can get sunburnt, including people with dark skin.

  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.

  Sunburn is an inflammation of the skin caused by overexposure to ultraviolet (UV) radiation from the sun and tanning beds. […] UV radiation can also damage the eyes, although no surface burn is apparent. […] People with certain pigment disorders (such as albinism) and those with fair skin are at the highest risk of suffering mild to severe sunburn. […] The American Academy of Dermatology classifies skin types into six categories (in terms of susceptibility to sunburn) for skin colors ranging from fair to black. […] The skin contains a pigment called melanin. It colors the skin, imparting a wide variety of skin tones. Melanin blocks some of the UV rays from penetrating the skin. […] Repeated overexposure to ultraviolet rays can also scar, freckle, dry out, and wrinkle the skin prematurely; moreover, frequent overexposure to ultraviolet rays can increase the risk of developing eye cataracts and macular degeneration, a leading cause of blindness.

  Sunburns all start with melanin and UV rays. The UV rays found in sunlight and tanning beds damage the skin by damaging the DNA inside of cells. Once the DNA is damaged, the cell usually dies. Melanin is the skin’s defense against this damage. […] The redness of a sunburn comes from the body flooding the area with blood to treat the damage and from inflammation of the skin. […] „Melanin is a natural sunscreen,” said Gary Chuang, an assistant professor of dermatology at Tufts University School of Medicine. „When your body senses sun damage, what it does is, it starts sending out melanin into surrounding cells and tries to protect them and shield them from getting more damage.” […] How long a person spends in the sun, combined with their skin type, determines if and when a person burns. Darker people don’t sunburn because they have more natural sunscreen than those with less melanin. […] Dermatologists use the Fitzpatrick Scale to determine a person’s risk of sunburn by their skin type, according to Dr. Sharad P. Paul.

  Individuals with Fitzpatrick skin phototypes I to III are more prone to sunburn because their skin contains less melanin pigment, which is crucial in shielding against UV radiation. […] Inadequate sun protection can result from not applying sunscreen frequently enough, using sunscreen with a low sun protection factor (SPF), and not wearing protective clothing in the sun. […] Sunburns might appear inconsequential, but closely monitoring them during the acute period is essential. […] UV exposure accelerates premature aging and heightens the risk of skin cancer. […] Chronic occupational exposure and occasional recreational sun exposure pose risks to individuals. […] Applying sunscreen consistently and appropriately with a higher SPF, wearing sun-protective clothing, and seeking shade can protect against sunburns and the associated skin damage.

  Sunburn is a radiation burn, caused when the ultraviolet (UV) rays of sunlight damage DNA in the upper layer of skin cells. […] The particles that transmit light (photons) from UVA rays interact with the skin and this damages the skin’s proteins and membranes, as well as DNA. […] Photons from UVB rays are absorbed by DNA itself, and the extra energy can cause some of the DNA to link up incorrectly. […] Immune cell invasion begins while you’re still sitting on the beach, but increases about an hour after you come in from the sun. […] Some of the immune cells start cleaning up skin cells in self-destruct mode, while others release chemicals that further damage weakened cells. […] Within several hours, blisters form where whole layers of keratinocytes have been killed.

  According to the American Cancer Society, most of the more than one million skin cancers diagnosed each year in the U.S. are considered sun-related. […] There is also strong evidence suggesting that exposure to UV rays, both UVA and UVB, can cause skin cancer. […] UV radiation may promote skin cancer in two different ways: By damaging the DNA in skin cells, causing the skin to grow abnormally and develop benign or malignant growths. […] By weakening the immune system and compromising the body’s natural defenses against aggressive cancer cells. […] Actinic keratoses are considered the earliest stage in the development of skin cancer, and are caused by long-term exposure to sunlight.

  Sunburn results from too much sun or sun-equivalent exposure. Almost everyone has been sunburned or will become sunburned at some time. […] One or more blistering sunburns in childhood or adolescence more than double a person’s chances of developing melanoma later in life, according to the Skin Cancer Foundation. […] A person’s risk for melanoma doubles if he or she has had five or more sunburns at any age. […] Severe untreated sunburn can cause shock (poor circulation to vital organs) and even death. […] More severe cases (sun poisoning) are complicated by severe skin burning and blistering, massive fluid loss (dehydration), electrolyte imbalance, and possibly infection. […] With too much exposure, severe untreated sunburn can cause shock (poor circulation to vital organs) and even death. […] Chronic sun exposure may lead to premature aging, severe wrinkling, pigmented skin lesion development (moles), and various malignant (cancerous) skin tumors.

  Sunburns all start with melanin and UV rays. The UV rays found in sunlight and tanning beds damage the skin by damaging the DNA inside of cells. Once the DNA is damaged, the cell usually dies. Melanin is the skin’s defense against this damage. […] The redness of a sunburn comes from the body flooding the area with blood to treat the damage and from inflammation of the skin. […] „Melanin is a natural sunscreen,” said Gary Chuang, an assistant professor of dermatology at Tufts University School of Medicine. „When your body senses sun damage, what it does is, it starts sending out melanin into surrounding cells and tries to protect them and shield them from getting more damage.” […] How long a person spends in the sun, combined with their skin type, determines if and when a person burns. Darker people don’t sunburn because they have more natural sunscreen than those with less melanin.

  https://www.cancer.org.au/blog/what-happens-to-your-skin-when-you-get-sunburnt

  Sunburn is a radiation burn, caused when the ultraviolet (UV) rays of sunlight damage DNA in the upper layer of skin cells. […] The particles that transmit light (photons) from UVA rays interact with the skin and this damages the skin’s proteins and membranes, as well as DNA. […] Photons from UVB rays are absorbed by DNA itself, and the extra energy can cause some of the DNA to link up incorrectly. […] Immune cell invasion begins while you’re still sitting on the beach, but increases about an hour after you come in from the sun. […] Some of the immune cells start cleaning up skin cells in self-destruct mode, while others release chemicals that further damage weakened cells. […] Within several hours, blisters form where whole layers of keratinocytes have been killed. […] 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. […] The melanin settles over the skin cells to shield them from future UV exposure.

• #111 Sunburn: Background, Pathophysiology, Etiology

  https://emedicine.medscape.com/article/773203-overview

  Sunburn is caused by excessive exposure of the skin to UVR. The UV spectrum can be divided into the following segments: Ultraviolet A (UVA)-I, 340-400 nm; UVA-II, 320-340 nm; Ultraviolet B (UVB), 290-320 nm; Ultraviolet C (UVC), 200-290 nm. […] Shorter-wavelength UVB rays are much more effective at inducing erythema than UVA rays are and thus are the principal cause of sunburn. […] The minimal single dose of UVR (energy per unit area) required to produce erythema after 24 hours at an exposed site is known as the minimal erythema dose (MED). This dose varies according to skin type. […] Multiple factors influence UVR-induced erythema, including the following: Wavelength – UVB is more erythemogenic than UVA; Skin type/pigmentation – Compared with patients who have type I-II skin, patients who have type IV-V skin require three to five times more UVR exposure to cause erythema; Hydration – UVR causes erythema more effectively in moist skin than in dry skin; Environmental reflection – Radiation is 80% reflected by snow and ice but only 15% reflected by sand; Ozone coverage – Increased levels of ozone filter out more UVR; Altitude – Thinner atmosphere at higher altitudes absorbs less UVR; Latitude – Exposure is greater nearer the equator; Time of day – UVR exposure is greatest from 10:00 AM to 4:00 PM, when the sun is highest in the sky; Season – In locations outside the tropics, UVR is much greater in summer than in winter; Cloud cover – Light clouds attenuate UVR by 10%, which may not be enough to protect from sunburn.

  Sunburn is an inflammation of the skin caused by overexposure to ultraviolet (UV) radiation from the sun and tanning beds. […] UV radiation can also damage the eyes, although no surface burn is apparent. […] People with certain pigment disorders (such as albinism) and those with fair skin are at the highest risk of suffering mild to severe sunburn. […] The American Academy of Dermatology classifies skin types into six categories (in terms of susceptibility to sunburn) for skin colors ranging from fair to black. […] The skin contains a pigment called melanin. It colors the skin, imparting a wide variety of skin tones. Melanin blocks some of the UV rays from penetrating the skin. […] Repeated overexposure to ultraviolet rays can also scar, freckle, dry out, and wrinkle the skin prematurely; moreover, frequent overexposure to ultraviolet rays can increase the risk of developing eye cataracts and macular degeneration, a leading cause of blindness.

• #137 Sunburn: Background, Pathophysiology, Etiology

  https://emedicine.medscape.com/article/773203-overview

  Sunburn is caused by excessive exposure of the skin to UVR. The UV spectrum can be divided into the following segments: Ultraviolet A (UVA)-I, 340-400 nm; UVA-II, 320-340 nm; Ultraviolet B (UVB), 290-320 nm; Ultraviolet C (UVC), 200-290 nm. […] Shorter-wavelength UVB rays are much more effective at inducing erythema than UVA rays are and thus are the principal cause of sunburn. […] The minimal single dose of UVR (energy per unit area) required to produce erythema after 24 hours at an exposed site is known as the minimal erythema dose (MED). This dose varies according to skin type. […] Multiple factors influence UVR-induced erythema, including the following: Wavelength – UVB is more erythemogenic than UVA; Skin type/pigmentation – Compared with patients who have type I-II skin, patients who have type IV-V skin require three to five times more UVR exposure to cause erythema; Hydration – UVR causes erythema more effectively in moist skin than in dry skin; Environmental reflection – Radiation is 80% reflected by snow and ice but only 15% reflected by sand; Ozone coverage – Increased levels of ozone filter out more UVR; Altitude – Thinner atmosphere at higher altitudes absorbs less UVR; Latitude – Exposure is greater nearer the equator; Time of day – UVR exposure is greatest from 10:00 AM to 4:00 PM, when the sun is highest in the sky; Season – In locations outside the tropics, UVR is much greater in summer than in winter; Cloud cover – Light clouds attenuate UVR by 10%, which may not be enough to protect from sunburn.

But the more damage your DNA experiences over time, the more likely mutations are to accumulate and get out of hand, which is why repeated sunburns increase the risk of skin cancer. […] The body also has ways of adapting to UV exposure. […] For instance, Pellois said cells respond to UV by producing more melanin, the pigment involved in tanning and skin color. Melanin can absorb some UV and convert it to a form that won’t cause harm, making people with more melanin more resistant to sun exposure. […] Many other factors, even the antioxidant content of foods, can change a person’s sensitivity to UV exposure.

  Sunburn hurts you in more ways than one. The danger goes far beyond any short-term pain, redness and discomfort, because after the sunburn fades, lasting damage remains. Sunburn accelerates skin aging and is a leading cause in the majority of cases of basal cell carcinoma, squamous cell carcinoma and melanoma, the deadliest form of skin cancer. […] YOUR RISK of developing potentially deadly melanoma DOUBLES with a history of 5 or more sunburns. […] Sunburn is an inflammatory reaction to ultraviolet (UV) radiation damage to the skin’s outermost layers. At the heart of it all is melanin, a pigment that gives your skin its color and defends it against the sun’s rays. Melanin works by darkening your unprotected sun-exposed skin. The amount of melanin you produce is determined by genetics, which is why some people get sunburned while others tan. Both are signs of cellular damage to the skin. For people with less melanin, prolonged unprotected sun exposure can cause skin cells to become red, swollen and painful, also known as sunburn. Sunburns can range from mild to blistering.

[…] Genetics determines how much melanin you make, and those with less of it, including fair-skinned people, tend to burn more easily, while those with more melanin might tan more. But a sunburn can happen to any type of skin, especially after prolonged, unprotected sun exposure. […] Its important to know that a tan still signifies cellular damage to the skin. […] Skin will heal from a sunburn, but too much sun exposure can create long-term damage to the skin, including accelerating skin aging and potentially causing skin cancer. Even without a burn, sun exposure can cause cellular damage that can become cancerous. […] Plus, sunburns add up. The more you burn, the greater your risk of skin cancer.

  Sunburn is an acute, transient, inflammatory response of the skin to excessive exposure to ultraviolet (UV) radiation from natural sunlight or artificial sources (eg, tanning beds, phototherapy devices). Both ultraviolet B (UVB; 280 to 320 nm) and ultraviolet A (UVA; 320 to 400 nm) can cause sunburn, but the wavelengths that are the most effective at inducing erythema are in the UVB range. […] Susceptibility to sunburn is a marker of genetic susceptibility to skin cancer and is associated with an increased risk of melanoma at all ages. […] Sunburn is common and occurs in individuals with all skin types. In the United States, the estimated sunburn prevalence (≥1 sunburn in the past 12 months) among all adults was approximately 34 percent in 2005, 37 percent in 2010, and 31 percent in 2015.

  Sunburns occur when you’ve spent too much time exposed to the sun’s UV rays (or the UV rays of a tanning bed or sun lamp). […] The reason some sunburns get so itchy has to do with the inflammatory response that happens when your body is exposed to UV rays, explains Erika Gray, Pharm.D., chief medical officer and co-founder of Toolbox Genomics. […] When the skin is damaged [from UV rays], inflammation pathways are triggered, which causes redness and itchiness, Dr. Gray explains. […] Dr. Goldman explains that the damaged skin releases certain chemicals [including histamine] that trigger nerve endings and leads to itching, but also the dryness and peeling of your sunburned skin contribute to itchiness. […] According to the National Institute of Health (NIH), histamine levels in the body are four times higher after UV exposure. Elevated levels of histamine in the body are associated with itching.

  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.

  Spending enough time in the sun without adequate protection can leave us looking and presumably feeling like a lobster ready for the plate. […] The conventional explanation for the skin’s painful inflammation response involves a cascade of effects triggered by breaks in the tissue’s DNA. […] It now seems we might have had that key detail incorrect all along. According to a new study involving mice and human skin cells, the first moments of sunburn are a little different from what anybody expected. […] „Sunburn damages the DNA, leading to cell death and inflammation. So the textbooks say,” says Anna Constance Vind, a molecular biologist from the University of Copenhagen who led an investigation that challenges what we thought we knew about sun damage. […] „But in this study we were surprised to learn that this is a result of damage to the RNA, not the DNA that causes the acute effects of sunburn.”

  Sunburn is caused by excessive exposure of the skin to UVR. The UV spectrum can be divided into the following segments: Ultraviolet A (UVA)-I, 340-400 nm; UVA-II, 320-340 nm; Ultraviolet B (UVB), 290-320 nm; Ultraviolet C (UVC), 200-290 nm. […] Shorter-wavelength UVB rays are much more effective at inducing erythema than UVA rays are and thus are the principal cause of sunburn. […] The minimal single dose of UVR (energy per unit area) required to produce erythema after 24 hours at an exposed site is known as the minimal erythema dose (MED). This dose varies according to skin type. […] Multiple factors influence UVR-induced erythema, including the following: Wavelength – UVB is more erythemogenic than UVA; Skin type/pigmentation – Compared with patients who have type I-II skin, patients who have type IV-V skin require three to five times more UVR exposure to cause erythema; Hydration – UVR causes erythema more effectively in moist skin than in dry skin; Environmental reflection – Radiation is 80% reflected by snow and ice but only 15% reflected by sand; Ozone coverage – Increased levels of ozone filter out more UVR; Altitude – Thinner atmosphere at higher altitudes absorbs less UVR; Latitude – Exposure is greater nearer the equator; Time of day – UVR exposure is greatest from 10:00 AM to 4:00 PM, when the sun is highest in the sky; Season – In locations outside the tropics, UVR is much greater in summer than in winter; Cloud cover – Light clouds attenuate UVR by 10%, which may not be enough to protect from sunburn.

[…] Actinic keratosis and all types of skin cancer, particularly non-melanoma types (basal and squamous cell cancer), are directly linked to sun exposure. […] Many people get the bulk of their sun exposure during childhood, and it has been shown that even one childhood sunburn increases the risk of developing skin cancer later in life. […] Any sun or other UV exposure, including a gentle tan, increases the risk of skin cancer. […] The Sun, like any star, emits vast quantities of energy across a range of wavelengths. […] Much of the energy emitted by the Sun is shorter-wave, more powerful radiation, most of it in the form of ultraviolet (UV) light. […] UV is classified into 3 degrees of energy: UVA, UVB, and UVC.
