Sun Protection

Overexposure to the sun and UV rays is rarely obvious at the time, -- and on many occasions, probably quite unintentional. However repeated exposure has rather more adverse long-term implications for our bodies and our health.

The sun’s rays are actually a major source of vitamin D and help the body’s systems acquire much needed calcium for building healthy bones. However, most people don’t need to spend large amounts of time exposed to the sun in order to get their required amount of vitamin D.

In fact, the body’s health can actually suffer negative effects when it’s exposed too long to the sun’s rays, especially if it’s unprotected. Results can vary from skin and eye damage to immune system suppression and ultimately cancer, even for the young.

There are three kinds of invisible ultraviolet (UV) rays in the sun that reaches earth: UVA, UVB, and UVC. When these rays come in contact with our skin, affects of UVA and UVB can be - tans, burns and other reactions (e.g. like acne and cancer).

It’s also notable that the effects of all UV rays are not the same. Depending upon the season, time of day and place on the planet in relation to the sun - (i.e. your altitude and latitude), the rays’ intensities vary. For example, during summertime, UV rays are at their strongest. Between 10 a.m. and 4 p.m., the rays are strongest. And close to the equator and at high altitudes (where air and cloud cover are less, resulting in increased harmful penetration of UV rays into the environment), the rays are also strongest.

The damage that occurs beneath the skin as a result of sunburn is considerably ‘less obvious’ at the time of exposure, and could take years to produce symptoms visible to the naked eye.

The fact that damage caused to skin cells during sunburn can not only accelerate the aging process, but also increase the risk of cataracts and skin cancer, should certainly demand our attention.

When faced with the potential risk of having to treat more than just the temporary symptoms and pain of sunburn, doesn’t it make more sense to avoid the risk in the first place? Therefore, seek prevention rather than cure!

When you are going out on a sunny day, remember these tips to have healthy skin even after tanning for quite a long period:

1. Wear protective clothing, including a long-sleeve shirt and a hat. Consider the ‘additional’ protection of an umbrella or shade where appropriate.

2. Avoid sun exposure between 10 am and 3 pm if at all possible.

3. Remember that UV rays are present even on cloudy days.

4. Remember that sunlight is strongly reflected from sand, snow, ice, water and concrete, which can intensify your direct sunlight exposure.

5. Apply sunscreen containing a sun protection factor (SPF) of at least 15, at least 15 minutes before going out into the sun.

6. Reapply sunscreen at regular intervals while out in the sun, especially if you are perspiring heavily or swimming.

7. Remember that UV overexposure is not limited to ‘sun exposure’. Sunburn can also occur as a result of UV exposure from other sources including tanning beds/lamps, welding arcs etc.

Prevention is a far better treatment than cure. In the event however, that you discover any unusual moles or growths on your skin – (particularly if they’re irregular in shape, bleed, itch, or appear to be changing) - consult your healthcare provider as soon as possible.

After following the tips above, it is sure that you will have healthy skin and a happy life.

Just a word, I highly recommend Sungazing 101 by Greg Aurand. It contains a lot of helpful information about sun protection. To get more info,
