Mistakes that harm your skin!

admin — Mon, 27 Sep 2010 11:05:23 +0000

Slather on sunscreen, check your skin regularly for suspicious marks and moles—for the past four years, Cosmo has been reminding readers to adopt these three big-picture healthy-skin habits so you don’t end up another skin-cancer statistic. The numbers are scary: cases of melanoma
—the deadliest form of skin cancer—among young women have doubled in the past few decades, and melanoma is the most prevalent cancer in women in their 20s.

But protecting yourself is more than just adopting a few large-scale pro-active measures. It’s also crucial that you take a close look at your lifestyle and catch any hidden risk factors that leave you more susceptible to skin cancer without your even realising it. With this in mind, we consulted top dermatologists, zeroing in on the five mistakes young women make.

Mistake 1:
You use moisturiser as sunscreen
Moisturiser infused with sunscreen is one of the best beauty-product combos since the compact, affording you extra SPF protection. The problem, however, is relying on it as your only SPF defense.

“Many moisturisers have an SPF of only 15, and because it’s more of a beauty product, women tend not to apply it as thickly as they should,” says Stanley J. Miller, M.D, associate professor of dermatology at Johns Hopkins Hospital and spokesperson for the American Academy of Dermatology. “They might be getting an SPF of only about 7…and even less if they don’t re-apply their moisturiser every couple of hours.” While moisturiser is a must for skin hydration, if you’re going to be outside for more than 15 minutes, apply a facial sunscreen as well.

Mistake 2:
You haven’t checked out your family cancer history
True, most cases of skin cancer—especially basal cell and squa mous cell carcinomas, the less deadly forms of the disease—are directly caused by exposure to UV rays from either too much sun exposure or indoor tanning. But there’s also a genetic component to skin cancer that leaves some people more susceptible than others. This is especially important when it comes to melanoma.

The facts: one first-degree relative (mom, dad, or sibling) with melanoma gives you up to a threetimes-greater risk of the disease over someone with no family history, according to a study in the Journal Of Investigative Dermatology. It also sets you up for developing melanoma earlier: the American Society of Clinical Oncology reports that the average age for melanoma to be diagnosed in people with a family history is in their 30s; the average age among the general public is in their 50s.

“There’s a strong hereditary pre-disposition to melanoma—behaviours like the whole family balking at using sunscreen can play a role, but it also boils down to genetics,” explains Albert Lefkovits, M.D., associate clinical professor of dermatology at the Mount Sinai School of Medicine. If a second-degree relative (grandparents, cousins) has had melanoma, your risk may be one-and-a-half times greater. And it’s not about a family history of just skin cancer but other cancers as well. You should alert your dermatologist if anyone in your family has had both melanoma and pancreatic cancer or melanoma and breast or ovarian cancers. At least two genes have been linked to familial melanoma, and some mutations in these genes may predispose you to these other cancers.

Mistake 3:
You bum a few cigarettes sometimes
Lighting up at parties or grabbing a cigarette or two at happy hour may allow you to stay just shy of officially being tagged a smoker. But in terms of the damage it does, your not-every-day habit still raises your risk.

Toxins in cigarette smoke are poison to your skin cells. Not only do these toxins accelerate the aging process so skin develops fine lines and age spots, but they also trigger the DNA damage that can put you in line for skin cancer, says Elizabeth Tanzi, M.D., co-director of the Washington Institute of Dermatologic Laser Surgery. This may explain why studies have shown that smokers have higher rates of squamous cell carcinoma.

If that’s not enough, having smoke wafting around your face also contributes to DNA damage as well as fine lines.

Mistake 4:
You don’t check your head and neck for suspicious marks

Only about 6 percent of melanomas strike on the head or neck. But when they do, they’re deadlier: a 2008 University of North Carolina study found that people with scalp or neck melanomas die at nearly two times the rate of those with it on their arms or legs.

“There are a lot of blood vessels in the scalp and neck, which may make it easier for melanoma to circulate through the body and cause cancer in other organs,” says Naomi Lawrence, M.D., director of dermasurgery at Cooper Hospital in New Jersey and spokesperson for the American Academy of Dermatology. “Your hair may also hide these cancers, so you don’t find them until they are at a later stage.”

Make it easier to see your scalp by parting your hair with a blow dryer or brush to check it in a mirror. Or ask your stylist to keep an eye out for anything suspicious. “A lot of my patients were sent to me by their hair dresser or barber,” says Dr Lawrence.

Mistake 5:
You work (or once worked) outdoors and forgot about the sun

Because sun damage is cumulative, even bits of unprotected exposure on the job—15 minutes of waitressing at an outdoor cafe, 25 minutes of teaching swimming—increase your cancer odds if you went sans sunscreen.

If your outdoor workdays are in the past, be a little more proactive about checking for marks and moles, suggests Dr Lefkovits, and let your dermatologist know your job history. Should you currently work outside, slather on sunscreen, protect yourself with a hat and/or sunglasses, and take breaks in the shade.

If Dark Chocolate is Healthy — Do Pigs Now Fly?

Ask 20 people their reaction to the word “Chocolate”, and you will probably get these responses … yummm, awesome, contentment, relaxing, delicious, calming … but HEALTHY?

Chocolate is a treat, a candy, an indulgence that for centuries has been enjoyed worldwide. Chocolate can quiet a crying child, impress a romantic interest, and add comfort to a relaxing moment … but HEALTHY? Oh yea … so it appears!

Recently, there has been much publicity about the cardiovascular benefits from antioxidants found in Red Wine and Green Tea.

A recent study conducted by scientists at Cornell University found that cocoa powder, the base from which chocolate is made, contains nearly TWICE the antioxidants of red wine, and up to three times the antioxidants found in green tea.

It is now known that raw cocoa, derived from the FRUIT of the Cacao tree, contains more than 300 chemically identifiable compounds, making it one of the most complex food sources on this planet. In addition, it has been established that raw cocoa has the highest antioxidant value of ALL natural foods in the world!

Fresh cocoa is super-rich in strong antioxidants called flavonoids (up to 10% concentration per mass of cocoa). These flavonoids have been clinically proven to help maintain healthy blood flow and stabilize blood pressure. They also help keep fatty substances in the blood from congealing together, thus decreasing the risk of oxidation and clogging of the arteries.

Flavonoids are also known to help keep the blood platelets from sticking together … a condition that can lead to blood clots, heart attacks, and strokes.

The antioxidants found in dark chocolate help to neutralize naturally occurring ‘free radical’ molecules in the body. Free radicals, if left unchecked, can damage the core structure of healthy cells which leaves them susceptible to disease.

Free radicals can also alter the structure of the cell’s DNA, which is the blueprint for a cell to reproduce and duplicate itself. Damaged DNA can lead to malignancy, tumors, and cancer.

Healthy dark chocolate as a nutritional supplement is not merely all about antioxidants.

Cocoa is a good source of the minerals sulfur, calcium, zinc, iron, magnesium, copper, potassium, manganese, plus some of the important B vitamins.

Of these minerals, magnesium is by far the most important. Proper magnesium levels in the body are essential for a healthy heart and ensure its strength and vigor.

Magnesium helps regulate blood pressure and the heartbeat. It also decreases blood coagulation leading to lower blood pressure.

A deficiency in magnesium can have far reaching health consequences, including hypertension, heart disease, diabetes, joint problems, and PMT.

Just as with antioxidants, organic dark chocolate is the highest rated natural food for providing this heart healthy essential mineral.

Another mineral with a high concentration in cocoa is sulfur. Sulfur promotes healthy skin, helps build strong nails and healthy hair, helps detoxify the liver, and supports healthy functioning of the pancreas.

Organic dark chocolate also provides supplemental benefits for the brain.

Cocoa is a potent source for the amino acids which make the neurotransmitters known as serotonin and dopamine. These two agents help alleviate depression and stimulate feelings of well being.

Phenylethylanmine (PEA) controls our ability to focus attention and stay alert. It has also been indicated as an integral element in maintaining mental alertness and countering the onset of dementia.

Another healthy chemical compound found in healthy dark chocolate, 2% – 3% per mass, is ‘theobromine.

This health promoting compound stimulates the central nervous system, relaxing smooth muscles and dilating blood vessels. As a known diuretic, it has been clinically used to remove excess body fluids, reduce high blood pressure, and stimulate the heart.

Chocolate has been known as the “comfort” or “happy” food, and rightfully so.

Anandamide, a neurotransmitter, is found in significant quantities in cocoa. Anandamide occurs naturally in the brain, and is released when we are feeling good. The introduction of more of this ‘bliss chemical’ helps contribute to our feeling of having a ‘natural high’.

ABC news reported in 2005 that the average American consumes 11.5 pounds of chocolate per year. This amounts to a full 1% of the American diet. These numbers are really not surprising.

There is no doubt that for centuries, humans have maintained an ongoing love affair with chocolate. Accepting organic, healthy dark chocolate as a heart and mind healthy food instead of simply a feel good snack certainly takes some getting used to.

Try to imagine a conversation at the dinner table like this … “Billy, you’re not leaving this table until you finish your dark chocolate”?

Although that conversation seems hard to imagine, providing yourself and your family with a consistent diet rich in healthy nutrients DOES NOT, and Healthy Dark Chocolate may clearly be indicated as a wise menu addition.

However, not all “Healthy Dark Chocolate” products are created equal. The challenge now lies in determining which of these delicious, satisfying, cocoa rich products provide the most health benefits for you and your family.
