How does ‘Slow Sun’ cause damage?

‘Slow Sun’ or ‘Incidental Sun’ is the sun we get without even knowing it.   

When we get in and out of our car going to and from work we often do not realize we might be getting sun exposure.  Unfortunately, the small segments of exposure to harmful UV rays we get intermittently throughout our life actually add up.  It has been estimated up to 85% of the cumulative sun exposure comes from this ‘Incidental Sun.’  

What does chronic sun exposure do to the skin?

It can lead to signs of sun damage.  This includes roughness in texture, brown or red spot development and wrinkles most often.   These features are often felt to be signs of aging.   It is not as noticeable at first, but something does occur with continued exposure.  This something is the development of precancerous lesions termed ACTINIC KERATOSIS.  These are usually rough and scaling growths on the sun exposed part of the body.   In addition, high lifetime UV exposure can lead to an increased risk of BASAL CELL CARCINOMA and SQUAMOUS CELL CARCINOMA.  So each day we get some exposure we are increasing your risk of skin cancer.

Be aware of your cumulative sun exposure, even that from childhood.  All sun exposure plays a role in the development of skin cancer and precancerous lesions. Don’t forget to wear your sunscreen and cover up!

What could excessive sun exposure potentially do to my skin?

  • Increase signs of aging
    • Wrinkles
    • Leathery appearance
    • Pigment Changes
    • Age Spots
    • Loss of Elasticity
    • Broken blood vessels
    • Freckles
  • Greatly increase your chances of getting skin cancer
    • Basal Cell Carcinoma- the most common form of skin cancer found in the outer most layer of the skin
    • Squamous Cell Carcinoma- the second most common form of skin cancer that can cause disfigurement
    • Melanoma- the most serious form of skin cancer that is potentially fatal

Yes, you read that right. Exposing your skin to the sun without protection can cause you to look older, damage your skin and even potentially cause death. Skin cancer is a serious problem that most people overlook. Protecting your skin from the sun by taking the proper precautions, such as wearing sunscreen, can make you happier and healthier. Wearing your sunscreen can save your life!

Adults who use sunscreen daily can drastically reduce their risk of developing melanoma, the deadliest form of skin cancer, according to recent landmark research from Australia. Researchers found that daily application of an SPF 16 sunscreen to the head, neck, arms, and hands reduced melanoma incidence by half in study participants.

In the Australian study, led by epidemiologist Adele Green, MD, University of Queensland, more than 1,600 white Australian adults between age 25 and 65 were studied for more than a decade. The subjects were divided into two groups, one told to continue using (or not using) sunscreen as they always had, the other given careful instruction in proper daily sunscreen application. The subjects were monitored closely through daily self-reports of sunscreen use, as well as collection and examination of all the sunscreen containers they had used. Only 11 melanomas developed in the daily sunscreen users, vs. 22 in the control group, a 50 percent reduction. In addition, invasive melanomas (tumors that penetrate beyond the skin surface) were reduced by 73 percent (3 tumors vs. 11) and average thickness by more than half a millimeter in the daily sunscreen group.

The trial's findings are the first to provide strong direct evidence for a reduction in the incidence of invasive melanoma after regular application of broad-spectrum sunscreen in adults. The scientists acknowledge that the study was relatively small and needs to be reinforced by further research, but consider their results convincing enough to recommend daily sunscreen application, along with "other standard sun protection measures like avoiding midday sun and use of protective clothing."

A sunburn is the pink to red color our skin becomes as a warning sign and reaction to being in the sun too long.  Most of us have had at least one sunburn in our life.  Understanding why it happens and the possible consequences can help us avoid this harmful reaction in the future.

Sunburn is the skin’s response to an excess amount of ultraviolet (UV) rays of the sun.   The skin initially does not turn pink right away, but rather it often loses moisture and can feel tight or painful.   The skin will begin to turn pink or red, which might not show up for hours after the exposure.  Often we do not realize what has happened to our skin until it is too late. 

Even as little as 10 minutes of intense UV exposer can burn the skin causing redness, tenderness and swelling.   In response to UV rays, the outer layer of skin produces a tanning pigment called melanin.  This melanin is a protective agent which blocks some of the harmful UV rays which normally penetrate the skin.  Some of the harmful rays can cause damage to the skin’s DNA which can ultimately lead to skin cancer. 

Sunburns can have harmful effects on the body, even years after exposure.  Science has shown that even a single blistering sunburn in childhood or adolescence more than doubles a person’s chances of developing melanoma later in life. A person’s risk for melanoma, the most serious and potentially fatal form of skin cancer, doubles if he or she has had five or more sunburns. The two most common types of skin cancer, basal cell carcinoma and squamous cell carcinoma, are also directly related to sun accumulation over many years. The most common locations for these cancers are sun-exposed areas: the face, ears and hands.

It is so important to avoid sunburns if at all possible.  The most useful tip to avoid sunburn is to avoid the sun and protect the skin.   Wear sunscreen when you are outside, even for short periods.    Sunscreens with an SPF of at least 30 or higher which contain one of the following ingredients: titanium dioxide, zinc oxide or parsol 1789 (avobenzone) are best.  Also protective clothing and avoiding the sun a when it is at the worst, typically 10 a.m. to 4 p.m. is ideal.   Protecting your skin is essential to your health and well-being. Be sun smart this summer and protect your skin from the harmful rays of the sun!

It can be so tempting when the weather is finally beautiful and the sun is out in full strength after a long hard winter to spend as much time outside as possible. You just want to be outside all the time, and there is nothing wrong with that. However, many people do not fully understand that the sun can be very detrimental to your health. The rays of the sun can damage your skin and cause wrinkles, pigmentation and even skin cancer. Skin cancer is the most common type of cancer diagnosed in the U.S. today. It can even be deadly. It is vital to your health and the health of your family that you take the proper precautions when you will be exposed to the sun.

First and foremost, the best line of defense if you are going to be in the sun is wearing sunscreen. It is recommended that you use a sunscreen of at least 30 spf. This will effectively block out 97% of UVB rays. It is best to apply sunscreen about a half hour before you go out into the sun and then again right before you go out. This will provide you with the best protection possible. Another important aspect to remember is to choose the correct ingredients in your sunscreen. You will want to select a sunscreen that contains one of the following ingredients: titanium dioxide, zinc oxide or parsol 1789 (avobenzone). These ingredients will ensure that you are protected against UVB and UVA rays, which can cause damage to the skin.

Another way to protect yourself from the sun is to avoid it all together. Stay out of the sun between the hours of 10 a.m. and 4 p.m. when the sun is at its hottest. Seek shade whenever possible and wear protective clothing. Melanoma is a serious form of cancer that can be deadly. You increase your risk of skin cancer substantially when you expose yourself to the sun without protection. So remember next time you are heading out for a fun day in the sun, that it is imperative to protect yourself from the damaging rays you will be exposed to. I dare you to avoid the sun and take the proper precautions if you will be exposed. It could save your life.
