Effects Of Too Much Sun Exposure

Near-daily “safe sun” exposure-that is, 10 to 20 minutes o: unprotected exposure during peak hours of the day-is beneficial to health, but too much sun exposure to ultraviolet radia­tion is a major contributor to skin cancer. The most common sites of skin cancer are the areas exposed to the sun most often (face, neck, and back of the hands). Ultraviolet rays are strongest when the sun is high in the sky. Therefore, you should avoid prolonged sun exposure between 10:00 a.m. and 4:00 pm. Take the shadow test: If your shadow is shorter than you, the ultraviolet (UV) rays are at their strongest.

There are three main types of skin cancer, each named after the type of cell from which they originate:

Basal cell carcinoma. Basal cells form the base, or the innermost layer of the epidermis.

Squamous cell carcinoma. Squamous originates from the word “scale.” These flatter cells from the outside layer of the epidermis and shed as new cells form.  Melanoma originates in cells that Create melanin, which gives color to skin.

Basal and squamous cell carcinoma require treatment but in the majority of cases do not spread to other parts of the body. Melanoma. The most deadly type of skin cancer, can appear quickly and metastasize in as little as 6 months. In 2016, it caused approximately 10,130 deaths in the United States. That number is expected to double by 2030. About 20 percent of Americans will develop skin cancer in their lifetime. Treatment for no melanoma skin cancer increased by more than 75 percent between 1992 and 2006. Melanoma is the number-one cancer killer of young women and increased 800 and 400 percent in young women and young men, respectively, between 1970 and 2009.

Consequences Of Sun Exposure.

One to two blistering sunburns can double the lifetime risk for melanoma, even more so if the sunburn takes place prior to age 18, when cells divide at a much faster rate than later in life. A person can easily be overexposed during a day in the sun sooner than they expect and not realize until later in the day when the sunburn becomes painful and the damage is already done. Overexposure can be difficult to predict because the strength of the sun exposure varies according to the time of year, a location’s latitude and elevation, and the sun’s reflection off

snow or water, among other factors. Be sure to understand how sun exposure changes by studying the “Sun Exposure” behavior modification planning. Further­more, nothing is healthy about a “healthy tan” Tanning of the skin is the body’s natural reaction to permanent and irreversible damage from too much exposure to the sun. Even small doses of sunlight add up to a greater risk for skin cancer and prema­ture aging. The tan fades at the end of the summer season, but the underlying skin damage does not disappear.

The stinging sunburn comes from ultraviolet B (UVB) rays, which are also thought to be the main cause of prema­ture wrinkling and skin aging, roughened/leathery/sagging skin, and skin cancer. Unfortunately, the damage may not become evident until up to 20 years later. By comparison, skin that has not been overexposed to the sun remains smooth and unblemished and, over time, shows less evidence of aging.

Sun lamps and tanning parlors provide mainly ultraviolet A (UVA) rays. Once thought to be safe, they too are now known to be damaging and have been linked to melanoma. As little as 15 to 30 minutes of exposure to UVA rays can be as dangerous as a day spent in the sun. Similar to regular exposure to sun, short-term sun exposure to recreational tanning at a salon causes DNA alterations that can lead to skin cancer.

Sun damage skin and its protection

To rejuvenate your skin, you must first motivate your bodies. Natural repair mechanisms. But you cannot repair your skin if it is frequently existence blasted by UV rays and is therefore forced to disburse its energy on defending against new wounds rather than healing old ones. I’m asking you to give your skin a ten-week vacation from the stress of normal wear and tear. To do so, sun damage skin protection for the next ten weeks you will· need to wear as strong a sunscreen or sunblock as you possibly can every day on your face, neck, hands, and other exposed areas to sun damage skin.

Sunscreen filters out most of the dangerous rays, whereas sunblock pre­vents any UV rays from being absorbed by the skin. Even if you· have a dark complexion and do not burn easily, you should still wear a sunscreen. Wearing a sunscreen will not only prevent further damage but will allow your skin to begin the healing process, and it will be tremendously therapeutic.

Studies show that if mildly sunburned skin is covered with sunblock, it will continue to repair itself even during subsequent exposure to the sun. The lesson is clear: The first step in restoring your skin to a more youthful condition Is to protect Sun damage skin it from additional UV damage.

So in addition to wearing a sunscreen or sunblock, for the next ten weeks try to avoid being Outdoor for prolonged periods, especially during the peak burning hours of 10′.00 am to 3.00 pm.

Use the best sunscreen

Be sure you select your sunscreen sensibly. All are not equally operative, and maximum do only half the job. For example, while sunscreens are fairly effective at screening UVB rays, they are not particularly effective against UVA rays. Finding a sunscreen that protects against both is often difficult, mainly because it is not easy to tell by reading the label. In order to be sure that you are getting adequate UVA protection from sun damage skin.

 People with oily skin may find that Parsol 1789 makes their skin even more oily and prone to acne; they should therefore look for a sunscreen designed specifically for oily skin or use a sunblock.

As many of you know, sunscreens are rated by SPF or sun protection factor. A sun protection factor of 15 would mean that if it normally takes a person ten minutes to burn, with SPF of 15, he can stay out in the sun fifteen times longer ore burning. You should wear a sunscreen with an SPF’ of least 15. Unfortunately, too many people assume this means you can go out into the sun for 150 minutes without worrying about damage. That is not the case. Remember, there are also UVA rays to worry about. UVA rays do not typically cause a burn. But they do cause serious long-term damage to the sun damage skin subcutaneous layers.

Use SunBlock

Another option is to use a sunblock that actually forms a physical barrier between your skin and UV rays. Using a sun block is like wearing a T-shirt on your face. Sunblock’s contain micronized titanium dioxide, and although they may be less irritating than sunscreens for some people, they are a bit more protection from sun damage skin

Difficult to use because if not applied evenly, they can form white streaks.

Cosmetics Companies have recently started including sun screens in their moisturizers and foundations. Keep in mind that these products do not provide the same UVA protection as products containing Parsol 1789. And even if you use a combination sunscreen, and foundation, you will still sunscreen on your hands, neck, and.other exposed areas.
