Be Sun Smart
May 3, 2011
While most of us love the hot, sunny days, we have become increasingly aware of the perils associated with spending too much time outdoors.
Sun Damage is cumulative; skin can repair superficial damage like the redness and soreness of sunburn, but the underlying damage remains. Once our natural defenses against harmful UV rays are gone, you cannot get them back. Understanding UV, SPF and UPF will help you with having a safe summer...
Understanding UV Rays.
UV Rays are classified as UVA, UVB, UVC, The amount of UV rays reach your body is affected by where you are on the earth. In addition, reflections from sand, pavement, snow and water increase UV exposure.
1.UVA rays cause skin aging and wrinkling and contribute to skin cancer, such as melanoma
2.UVB rays are also dangerous, causing sunburns, cataracts (clouding of the eye lens), and immune system damage
3.UVC rays are the most dangerous, but fortunately, these rays are blocked by the ozone layer and don't reach the earth
The UV index was developed in 1994 and is based on the amount of time spent in the sun that it would take for a fair-skinned person to burn. The UV index is now announced in most papers, TV weather spots and on our phone as an app.
UV Index Risk Estimated Time
0-2 Low 1 Hour
3-5 Moderate Less than 20 minutes
6-7 High Less than 15
8-10 Very High Less than 10 minutes
SPF means Sun Protection Factor and is found on most sunscreens
SPF measures the length of time a product protects against the skins reddening from UVB, compared to how long the skin takes to redden without protection. If it takes 20 minutes without protection, using 15 SPF sunscreen theoretically prevents reddening 15 times longer about 5 hours.
SPF 15 protects from 93.3% of UVB light, leaving 6.7% available to penetrate the skin. Application and frequency of sunscreen throughout the day can be found on most products.
UPF means UV Protection Factor and is found on apparel.
The protection given to the skin by the fabric is indicated by its UPF, the higher the UPF the better the protection. A sweat shirt has high protection but who wants to swim in that?
UPF Rating Amount of Protection % UV Rays Blocked
15-24 Good 93-95% UV
25-39 Very Good 96-97%
40-50 Excellent 98% ++
Did you know a Cotton T-shirt only has 5 UPF, less when wet, that is like wearing sunscreen of 5 SPF sunscreen? A growing number of clothing companies are now creating fun and functional swim and play wear. Imagine having the ability to cut the amount of harmful and potentially dangerous UV light by simply changing apparel.
Taking certain medications such as quinolones, tetracycline, sulfonamides, amiodarone and tricyclic antidepressants makes the skin more susceptible to the effect of UVA radiations, so it is particularly important to use sunscreen or sun protection apparel.
EpiPens are commonly carried by persons with severe allergies and a risk of anaphylactic shock. Epinephrine is stable at room temperature, EpiPen® should not be refrigerated, and neither should the EpiPen® Auto-Injector be exposed to extreme heat, such as in the beach bag or trunk of a car during the summer.
Sunburn usually reddens the skin immediately at the end of sun exposure and it starts to fade after several hours. Then, about 6 hours later, the redness returns and reaches its peak at about 24 hours.
What do you do for sunburn?
Take a cool (not cold) bath, or gently apply cool, wet compresses to the skin to help alleviate pain and heat. Apply pure aloe vera gel (available in most pharmacies or taken directly from within the leaves of the plant) to any sunburned areas. It's excellent for relieving sunburn pain and helping skin heal quicker.
Take a pain reliever like acetaminophen or ibuprofen and spray on over-the-counter "after-sun" pain relievers. (Do not, however, give aspirin to children or teens.)
Apply topical moisturizing cream to rehydrate the skin and help reduce swelling. For the most severely burned areas, apply a thin layer of 1% hydrocortisone cream. (Do not use petroleum-based products, because they prevent excess heat and sweat from escaping. Also, avoid first-aid products that contain benzocaine, which may cause skin irritation or allergy.)
If the sunburn is severe and blisters develop, call your doctor.
Even a single sever sunburn before the age of 20 increases the risk of developing skin cancer later in life. This does not mean that you get a free pass once you reach 20, sun damage is cumulative, and it builds with each sun exposure.
Skin cancers are generally categorized as both melanoma and non melanoma type. Non Melanoma skin cancers are further categorized as basal cell, carcinoma or squamous cell carcinoma.
Non melanoma type cancers are the most common these cancers rarely occur before 40 years of age and they are more common in men than in women. About 8-% of are basal cell carcinomas which are commonly associated with intense short-term sun exposures.
Basal Cell Carcinoma is general of 20-50 years between the time of sun exposure and the occurrence. Most appear on the head, nick and upper back.
Melanoma Skin cancer accounts for only 4% of skin cancers but it causes about 70% of skin cancer deaths. Men it appears mostly on the upper back, women the back of the calf as well as the back.
A number of website with images of what you should be looking for is available on most Cancer sites. Self-examination and a review with your Doctor are best.
