Sun-safe habits should begin in childhood and last a lifetime.

Build safe sun habits into your family’s daily routine and show them how you protect your skin. Children respond better when they watch their parents.

Begin by teaching them:

1. Slip on a shirt
2. Slop on sunscreen with SPF15 or higher
3. Slap on a hat.

These actions are designed to reduce exposure to sunlight and therefore minimise the risks involved.

Further advice is to avoid exposure to the sun when it is at its strongest – between mid-day and three in the afternoon. When you think about it, this is the traditional time when many Mediterranean countries have lunch followed by a siesta – both taken indoors thereby avoiding the worst effects of the sun. So plan outdoor activities around this time.

Melanoma 101

Melanoma is considered the most serious type of skin cancer. Though it doesn’t affect as many people as other skin cancers, melanoma causes the most deaths, reports the Mayo Clinic.

• How it occurs. Melanoma occurs in cells called melanocytes. These cells create melanin, which is responsible for skin pigment and helps protect against UV rays. When skin is exposed to UV light, melanocytes produce more melanin, tanning the skin.

Sometimes, these cells mutate, growing and dividing quicker than normal cells, according to the American Academy of Family Physicians. These cells clump together, forming tumors. If tumors are malignant, they can attack the healthy tissue. They also can spread and form new tumors throughout the body, which is common with melanoma — if it isn’t treated early enough.

• Who’s at risk. The following people are at increased risk for melanoma and need to be extra diligent about sun safety:
  • People with fair skin, because they have lower amounts of melanin and need greater protection
  • People living in southwestern states where sun exposure is strong
  • People with weakened immune systems
  • People who have a family history of melanoma
  • People who’ve suffered severe sunburn in childhood or recent years

Moles: Unusual vs. normal moles

You should see a dermatologist once a year to have your moles checked. In addition, keeping tabs on your moles is key to catching melanoma in its early stages.

Here’s a look at the differences between irregular moles (or dysplastic nevi, which can lead to melanoma) and regular moles.

• Dysplastic nevi can appear as a combination of tan, brown, red/pink moles and are often larger than 5 millimeters across, about ¼ inch.
• Ordinary moles are round or oval and have a concise edge that separates them from the rest of the skin. Dysplastic nevi have irregular edges and blend into the skin.
• Regular moles start as smooth spots on the skin and may become raised, creating a tiny bump. Dysplastic nevi tend to have a scaly, rough or rocky surface but also can be smooth.
• The typical number of moles is usually between 10 and 40 on a person’s body. Dysplastic nevi are found in large numbers (100 or more), although someone might have just a few.
• In men, harmful moles are often found between the shoulders and hips and neck and head areas. In women, they typically appear on the lower legs, shoulders and hips.

The ABCDEs of monitoring your moles

Here’s a quick way to check old moles that become irregular and new moles that develop, according to the American Academy of Family Physicians. If you answer yes to any of the questions below, see a doctor immediately.

• A (Asymmetry): If you were to split the mole in two, are the sides unequal?
• B (Border): Are the edges of the mole jagged or blurry?
• C (Color): Has the mole changed color (i.e., has the color spread or darkened? Is there a loss of color? Does the mole have multiple colors?)
• D (Diameter): Is the mole larger than ¼ in diameter?
• E (Elevation): Is the mole raised above the skin and rough?

Sun safety

Use these tips to keep your skin safe from melanoma and other skin cancers and sun damage.

• Don’t tan outdoors or use tanning beds. Remember that any sun exposure is damaging to skin, so there’s no safe way to tan (including that “base tan”).
• Wear sunscreen every day and apply it correctly. Though everyone knows that sunscreen is necessary, the majority of people don’t apply enough of it or as often as they should — creating a false sense of security, where you don’t get the full SPF but think you’re protected. Here’s how to ensure you’re fully protecting your skin.
  • Make sure to apply sunscreen 20 to 30 minutes before going outdoors.
  • Apply sunscreen with SPF 15 or greater. Look for ingredients such as titanium oxide, zinc oxide or avobenzone (Parsol 1789), which provide protection against UVA and UVB rays.
  • Use at least one ounce (a shot glass or two tablespoons) of sunscreen every time you apply.
  • Reapply every two hours even if a sunscreen is labeled “water-resistant.”These sunscreens can lose their effectiveness after 40 minutes in the water.
• Avoid sun exposure during peak hours: between 10 a.m. and 4 p.m.
• Wear sunglasses and a wide-brimmed hat.
• Seek the shade. However, being in the shade should never substitute for sunscreen, because the sand and concrete reflect UV rays. The sun also reflects off of water and snow, so be especially careful around these areas.

Put simply, the higher the SPF value, the longer the user will be able to stay in the sun without visibly burning. As an example, if someone would normally start to burn after 15 minutes in the sun when unprotected, by using an SPF8 sun-cream they should be able to stay out for 2 hours without visibly burning. If they use a Factor 20 sun-cream, in theory they could stay in the sun for as long as 5 hours without visibly burning.

Sun-creams earn their SPF rating by including ingredients which filter out UV radiation and reduce it’s effect on the skin. Because it is UVB that causes most of the visible adverse effects of sun exposure, most commercial sun-creams concentrate just on filtering this out and pay little attention to UVA radiation. However, as already explained, it is UVA that does the most damage in the long term and which we need protection from.

It has been suggested that the use of sun-creams that only filter out UVB radiation has encouraged people to stay out in the sun far longer that they would otherwise do, and that this has unwittingly increased their exposure to UVA to such an extent as to lead to the dramatic increases in skin cancer that we are currently seeing. The moral of this has to be to only use sun-creams that filter out both UVB and UVA radiation.

Until August 1999, the American Academy of Pediatrics (AAP) recommended against using any type of sunscreen on babies younger than 6 months, because their skin’s ability to metabolize and excrete chemicals may not be fully developed. This recommendation has been revised somewhat. You can use sunscreen on babies under 6 months if adequate clothing and shade aren’t available, but check with your pediatrician first. That doesn’t mean you should slather your baby in sunblock, though. Just apply a small amount of lotion to exposed areas.

For babies over 6 months, use a waterproof sunscreen designed for children. Choose a sunscreen labeled “broad spectrum,” which means it protects against both ultraviolet B (UVB) and ultraviolet A (UVA) rays. Zinc oxide and titanium dioxide sunscreens are good to use on particularly sensitive spots, such as the nose and lips.

The AAP and American Academy of Dermatology recommend an SPF of at least 15, but many experts recommend SPF 30 or higher for babies, and many baby sunscreen formulas have even higher SPFs. If possible, apply sunscreen 30 minutes before sun exposure and reapply it at least every two hours, especially if your baby has been playing in the water or has been sweating (even if the sunscreen is waterproof).

When trying a new sunscreen, do a patch test on your child’s back to make sure he doesn’t have a reaction to it. If he does develop a rash or redness at the test site, choose a hypoallergenic formula instead.

SPF, an abbreviation for sun-protection factor, is a number such as 15, 30, or 50 that indicates how long a topical sunscreen remains effective on the skin. A user can determine the duration of effectiveness simply by multiplying the SPF by the length of time it takes for him or her to suffer a burn without sunscreen.

Basal Cell Carcinoma  is a common form of skin cancer with almost 1 million cases each year in America. Treatment includes a procedure to remove the cancer, typically by cutting out the affected area or treating with a topical chemotherapy. If left untreated, the cancer will continue to grow. Individuals who have been diagnosed with basal cell carcinoma need sun protection to minimize UV exposure.

Bottom line – the sun is our friend.  We need it and it is wonderful for our spirits and our health. Enjoy it but safely and in moderation.
