What Are The Adverse Effects Of Sunbathing



Sunbathing, during which person sits or lies under direct sunshine, has contemporaneously come to be acknowledged as a fashionable leisurely activity. People usually prefer to sunbathe in scenic places where there is abundant sunlight, such as beaches, swimming pools, parks, and gardens. They tend to wear limited amounts of clothing such as swimsuits; indeed, some even prefer to go nude, this contention being a result of the fact that the primary purpose for sunbathing [especially in western regions] is to darken or tan their skin.

Some people, however, tend to sunbathe excessively, and this, especially when the adequate safety measures aren’t adhered to, leads them to suffer from sunburns. Sunburns are caused by the biologically harmful ultraviolet [UV] rays of the sun. It is now known that solar radiation, when speaking in terms of the consequences of exposure, is one of the primary sources of sunburn. Moreover, excessive exposure to these rays also contributes to other adverse effects such as the suppression of cellular resistance in terms of short term impacts and photo aging and skin cancer in concern to long term impacts. In addition to the already mentioned impacts of UV, other effects include:

Various Effects Of Ultra Violet Rays On Human Skin;
  • Sunstroke
  • Prickly heat
  • Dehydration
  • Premature [skin] Ageing
It would important to here acknowledge that although sunlight generically indicates health, it is also linked to all types of skin cancers caused by radiation. And while not all people are equally at risk, those at substantially more of a risk tend to be fair skinned and and/or have family histories of sensitive skin types. The presence of large number of freckles is also one of the more common indicators of an individual’s sensitivity towards the sun. Sunburns usually involve painful red or peeling skin, rash, nausea, fever and an increased risk of skin cancer. Consequently, people sunburns must wear long sleeved shirts and use hat or umbrella when they go in the sun rays as this prevents them from experiencing further deterioration. And while sunscreens or Sun blocks are also good sources of skin protection, it is important that the eye not be neglected; wrap around sunglasses which effectually block the suns rays are useful in this case.

Benefits Of Exposure To Sunlinght

However, there is evidence that the probable benefits of exposure to sunlight can be more important than the generally adverse affects on the incidence of skin cancer. For many people the small increase of the content of melanoma in the skin could easily outweigh the harmful effects in as much as the effect that sunshine has on mood. Behavioral changes could reduce the incidence of skin cancer. It is of utmost importance though, to keep in mind that people must avoid the midday sun, wearing appropriate clothing and a sun sunscreen. It is also advisable to avoid the sunbeds that are used for cosmetic tanning.

If you are a patient suffering from sunburns, it is essential to be cautious about sun exposure, especially if you are taking medication. This is since the combination of some medicines and sunlight can reduce the time essential to help rashes, skin aging, or very serious consequences like cataracts, blood vessel damage, and skin cancer. Certain drugs can also increase you sensitivity to light, raising the chance that these adverse reaction will occur.

Sunless Tanning: A safe Alternative to Sunbathing

How do sunless tanning products work?

Sunless tanning products, also called self-tanners, can give your skin a tanned look without exposing it to harmful ultraviolet (UV) rays. Sunless tanning products are commonly sold as creams, gels, lotions and sprays you apply to your skin. Professional spray-on tanning also is available at many salons, spas and tanning businesses.

The active ingredient in most sunless tanning products is dihydroxyacetone (DHA). When applied to the skin, DHA reacts with dead cells in the outermost layer of skin to temporarily darken the skin's appearance. The coloring doesn't wash off, but it gradually fades as the dead skin cells slough off — typically within a few days.

Most sunless tanning products don't contain sunscreen. If you spend time outdoors, sunscreen remains essential.



What about sunless tanning pills?

Sunless tanning pills, which typically contain the color additive canthaxanthin, are unsafe. When taken in large amounts, canthaxanthin can turn your skin orange and cause hives. Sunless tanning pills can also cause liver damage and lead to the formation of crystals in the retina of the eye (canthaxanthin retinopathy).

What can you expect from sunless tanning products?

Sunless tanning products typically go on clear. It usually takes about an hour to see results. Full color typically appears within eight to 24 hours. People who have medium complexions without freckles often get the best results.

Is sunless tanning safe?

Topical sunless tanning products are generally considered safe alternatives to sunbathing, as long as they're used as directed.

Keep in mind that spray-on tanning or mist-on tanning from a salon or spa is typically applied to all parts of your body, including your face, to ensure an even color. This creates a potential for the product to get into and around your eyes, near your nostrils or onto your lips. The risks, if any, of inhaling or ingesting DHA are unknown — so close your eyes and hold your breath while the tanner is applied. You may also want to request or bring along protective devices, such as goggles or nose plugs.

What's the best way to promote an even-looking tan with sunless tanning products?

Sunless tanning products can provide an even, natural-looking tan if they're applied correctly and carefully. For best results, follow the package directions carefully. In general:
  • Exfoliate first. Before using a sunless tanning product, wash your skin with a wash cloth or sponge to remove excess dead skin cells. If you typically shave your legs, do so before you apply the sunless tanning product for an even application.
  • Use a light touch. Apply the sunless tanning product evenly and lightly. Use sparingly on dry or thickened skin, such as over your ankles, knees and elbows. If necessary, ask someone to help you apply sunless tanner to hard-to-reach spots.
  • Save the tops of your hands for last. After you apply the product to your face and body, wash your hands with soap and water to avoid coloring your palms. Be sure to remove any product from under your fingernails. Then use a cotton ball to apply the sunless tanner to the top of each hand.
  • Take time to dry. Wait to dress until the sunless tanner dries completely.
Remember, most sunless tanning products don't contain sunscreen. If you spend time outdoors, protect your skin with generous amounts of sunscreen.
