91裸聊视频淭he phrase 91裸聊视频榟ealthy tan91裸聊视频� is an oxymoron,91裸聊视频� says Dr. Harvey Lui. 91裸聊视频淎 tan is a sign that you91裸聊视频檝e damaged your skin. Your body responds to that injury with a tan as a way of repairing the skin.91裸聊视频�

Lui91裸聊视频攁 medical dermatologist with the BC Cancer Agency and a professor of dermatology and skin science at UBC91裸聊视频攕ays that there are several myths about staying safe in the sun, one of which is that if you get a sunburn at the beginning of the summer season, you will then tan and be okay; hence his caution that there is no such thing as a healthy tan. 91裸聊视频淎 sunburn is nature91裸聊视频檚 warning that you shouldn91裸聊视频檛 be doing this.91裸聊视频�

Another myth is that if the sky is cloudy, the weakened sunlight will not be damaging to your skin. 91裸聊视频淭here is a significant amount of UV [ultraviolet] rays still reaching the earth. And if it91裸聊视频檚 cold, people might let their guard down. If it91裸聊视频檚 sunny but cold there91裸聊视频檚 still a risk, because it91裸聊视频檚 the invisible UV rays damaging the skin, not the heat.91裸聊视频�

Lui says that it takes decades for skin cancer to develop, and that the damage starts in childhood. 91裸聊视频淚t91裸聊视频檚 really important for people to realize that research is showing that the risk of developing melanoma [a malignant tumour] correlates with the sun you got early in life.

91裸聊视频淲ith early sun exposure, such as a few bad burns or tanning, the cells get damaged. It takes decades for the cancer to develop, so parents need to protect their children. Even if everyone started practising good sun prevention today, we would still be seeing an increase in skin cancer for the next 20 to 40 years.91裸聊视频�

Being in or around water during summer91裸聊视频攚hether it be a pool, lake, river, or ocean91裸聊视频攎eans people need to take extra precautions to keep their skin safe. 91裸聊视频淚f you91裸聊视频檙e by a pool, say, on a sunny day you91裸聊视频檙e getting lots of sun on your skin, and you could also be getting a reflected dose of light off the water.91裸聊视频�

Anyone going in the water needs to apply sunscreen before they do so. 91裸聊视频淭he sun91裸聊视频檚 rays can penetrate the water, and when your head is above the water you91裸聊视频檙e getting the sun plus a reflection from the water.91裸聊视频� Sunscreen also needs to be reapplied when you come out of the water.

When it comes to sunscreen, Lui says a common error is not applying enough. 91裸聊视频淧eople often use only a quarter or half as much as they need.91裸聊视频� And while people are pretty good about applying sunscreen to their face, they often forget to put it on their ears, behind their ears, and on the back of their neck.

He recommends that people look for a sunscreen with an SPF [sun protection factor] of 30 or higher. 91裸聊视频淭hirty is the bare minimum; as high as 50 or 60 is even better. It91裸聊视频檚 not more expensive.91裸聊视频�

People should also ensure that the sunscreen is a broad spectrum one, covering UVA and UVB rays, and should look for the logo of the Canadian Dermatology Association. 91裸聊视频淭hey have reviewed all sunscreens, and feel these ones are effective.91裸聊视频�

He adds that any sunscreen that is labelled as being specifically for children is a marketing thing, nothing more. 91裸聊视频淭here91裸聊视频檚 no such thing as sunscreen for children. There91裸聊视频檚 no difference. The same sunscreen can be used by everyone in the family.91裸聊视频�

Lui also cautions against buying spray-on sunscreen. 91裸聊视频淪unscreen in a spray bottle is convenient, but it91裸聊视频檚 very expensive, because you91裸聊视频檙e just spraying a lot of it into the air.91裸聊视频�

He adds that while some people get anxious about using sunscreen (91裸聊视频淭hey worry about putting chemicals on their skin91裸聊视频�), and acknowledges there is a theoretical concern that these materials might cause damage, a person would have to apply gallons of sunscreen to theoretically absorb trace elements of chemicals.

91裸聊视频淚t91裸聊视频檚 wiser to protect your skin than to avoid sunscreen.91裸聊视频� He notes that sun greatly accelerates the aging process, and increases wrinkles later in life. 91裸聊视频淚 tell people next time they91裸聊视频檙e in front of a mirror to look at their face and then look at their bum. They91裸聊视频檙e both the same age, but you don91裸聊视频檛 get wrinkles on your bum, because it doesn91裸聊视频檛 get exposed to the sun.91裸聊视频�

Since the sun91裸聊视频檚 rays are strongest between 11 a.m. and 3 p.m., Lui advises people to try to stay out of the sun during those hours. 91裸聊视频淚f you91裸聊视频檙e a gardener, the nicest time to garden is early in the morning or in the evening. It91裸聊视频檚 much safer and cooler.91裸聊视频� Gardeners should wear a broad-brimmed hat with a brim as wide as their palm extending all around it. 91裸聊视频淏aseball caps are cool, but they were designed to help a baseball player see better in sunlight, not protect him from the sun.91裸聊视频�

Since gardeners are often looking down, they need to apply sunscreen to their ears and neck. Hikers need to pay attention to these areas as well, especially if they are walking with their back to the sun.

Another myth about exposure to the sun surrounds Vitamin D. 91裸聊视频淪unlight helps make Vitamin D, but Vitamin D is also available through your diet or in supplements. And people think 91裸聊视频業f some sun is good for Vitamin D, a lot of sun must be better.91裸聊视频� Vitamin D comes in tinted bottles to protect it from the light. Extra Vitamin D is degraded by sunlight, and you will accumulate DNA damage and have a higher risk of skin cancer.91裸聊视频�

While some clothing is marketed as being designed to protect the skin from sun exposure, Lui says it91裸聊视频檚 fine to buy less-expensive clothing that has a nice tight weave.

91裸聊视频淭he simple rule of thumb is to hold the material up to the light and make sure none gets through. Jeans are a good example; no one gets a tan through jeans.

91裸聊视频淪imple things are fine. And common sense is the cheapest thing around.91裸聊视频�
