Safe Tanning?

All ultraviolet rays in sunlight - both U V A and UVB - are harmful to the skin, and the amount of damage depends on the length of time you stay unprotected in the sun. Long exposure to the sun may inflame your skin and cause it to swell. Even longer exposure results in burning, with blistering and peeling, and possibly heatstroke, which causes the temperature-regulating mechanism of your body to give up, which can make you very sick. For more on heat stroke, see the First Aid section.

Of course the most serious danger of sun tanning is the risk of skin cancer, which is higher in pale-skinned people. As you know, skin cancer has increased significantly in the last few years and this is almost entirely due to our obsession with a tan. Sunblocks are a necessity.

Another long-term hazard is wrinkles, which are caused by the sun destroying the collagen in the skin. A suntan ages the skin and there's nothing you can do to reverse it. Instead, protect your skin with the sunscreens in strong sun light. If you really must get a tan, use common sense and learn all you can about sun screens. Tan gradually over a period of time, with short session of exposure to the sun and use at least a number 15 or 20 SPF . BUT, no amount of tanning is safe for your skin.

(May 2003, update: I tanned a lot as a teen and into my twenties. I have had 4 precancerous lesions removed from my face (luckily no scars were formed). The dermatologist said it was from all those years of the sun, I didn’t use a sunscreen then). Save your skin now and it will look good for life. Later in that same year I had developed skin cancer on a small spot on my face from years of tanning. I have a small scarred area there now forever to remind me.

Why Use A Sunscreen?

Sunscreens block the harmful UVA and UVB rays of the sun. You will find that each sunscreen has an sun protection factor (SPF) which is equal to the amount of time you can stay in the sun without burning. So, if you are sitting in the sun for 10 minutes, and you apply a sunscreen with an SPF of 10, you can sit in the sun for 10 X 10 minutes without burning. Very pale-skinned people should use a very high SPF or a total sunblock.

Wear sunscreen with a sun protection factor (SPF) of at least 15 every day, even on cloudy days and when you don't plan on spending much time outdoors. Make sure the sunscreen blocks both UVA and UVB rays (referred to as "broad-spectrum" sunscreen). If you are going to be outside for a while, reapply sunscreen every 2 hours and after swimming or sweating. If you'll be in the direct sun, wear a sunscreen with a higher SPF, like SPF 30. If you'll be playing sports, make sure the sunscreen is waterproof and sweat-proof.

Skin Color

The color of you skin is determined by the amount of melanin it contains. This substance called melanin protects the skin from the sun's ultraviolet rays. A tan is visible proof that your skin is being damaged. When the ultraviolet radiation of the sun hits your skin, it stimulates cells known as melanocytes, which make the brown pigment called melanin. The melanocytes respond to the sun by making even more melanin to protect your skin from the sun. The melanin acts sort of like a barrier for the skin's cells and can give people the brown tint that is a suntan. We can't possibly tell you that getting a tan is safe, when it is not. Here as some examples of skin colors:

Fair skin
If you have fair-skin, your hair is light-colored or red, your skin is fair, and it is always hard for you to tan. (Sometimes freckled.) You tend to burn easily and quickly.

Olive skin
Your skin, hair and eyes are all brown or dark brown. You tan quickly without burning.

Black skin
Your skin, hair and eyes are very dark and you don't burn easily. Black skin can burn in strong sunlight.

Knowing your skin type will help you decide how long you can safely expose yourself to the sun without burning. If you have dark skin, you will be able to stay out longer than someone with pale skin, and you will burn less easily.

Long-term Effects Of The Sun

Melanin can only protect your skin so much. If you continue to be exposed to the sun, the UV radiation can eventually damage your skin. That damage shows up on fair-skinned and olive-skinned people as:

First Aid For Sunburns

Symptoms of sunburn usually appear within a few hours after exposure, and up until 24 hours after exposure and peak within 2 to 3 days.

Most sunburns are first-degree burns that cause the skin to become red, warm and tender to the touch. Second-degree burns are a more serious burn and can cause severe swelling, reddening, pain and blisters. Blisters are a sign that the burn has gone deeper than just the surface layer of the skin and has caused damage and the release of fluids from the cells in the lower layers of the skin. This results in bad blisters and breaks in the skin where bacteria and other organisms can enter. This is not a good situation and a person with a burn this badly should get some medical attention.
