香蕉视频直播淭he phrase 香蕉视频直播榟ealthy tan香蕉视频直播� is an oxymoron,香蕉视频直播� says Dr. Harvey Lui. 香蕉视频直播淎 tan is a sign that you香蕉视频直播檝e damaged your skin. Your body responds to that injury with a tan as a way of repairing the skin.香蕉视频直播�

Lui香蕉视频直播攁 medical dermatologist with the BC Cancer Agency and a professor of dermatology and skin science at UBC香蕉视频直播攕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. 香蕉视频直播淎 sunburn is nature香蕉视频直播檚 warning that you shouldn香蕉视频直播檛 be doing this.香蕉视频直播�

Another myth is that if the sky is cloudy, the weakened sunlight will not be damaging to your skin. 香蕉视频直播淭here is a significant amount of UV [ultraviolet] rays still reaching the earth. And if it香蕉视频直播檚 cold, people might let their guard down. If it香蕉视频直播檚 sunny but cold there香蕉视频直播檚 still a risk, because it香蕉视频直播檚 the invisible UV rays damaging the skin, not the heat.香蕉视频直播�

Lui says that it takes decades for skin cancer to develop, and that the damage starts in childhood. 香蕉视频直播淚t香蕉视频直播檚 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.

香蕉视频直播淲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.香蕉视频直播�

Being in or around water during summer香蕉视频直播攚hether it be a pool, lake, river, or ocean香蕉视频直播攎eans people need to take extra precautions to keep their skin safe. 香蕉视频直播淚f you香蕉视频直播檙e by a pool, say, on a sunny day you香蕉视频直播檙e getting lots of sun on your skin, and you could also be getting a reflected dose of light off the water.香蕉视频直播�

Anyone going in the water needs to apply sunscreen before they do so. 香蕉视频直播淭he sun香蕉视频直播檚 rays can penetrate the water, and when your head is above the water you香蕉视频直播檙e getting the sun plus a reflection from the water.香蕉视频直播� 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. 香蕉视频直播淧eople often use only a quarter or half as much as they need.香蕉视频直播� 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. 香蕉视频直播淭hirty is the bare minimum; as high as 50 or 60 is even better. It香蕉视频直播檚 not more expensive.香蕉视频直播�

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. 香蕉视频直播淭hey have reviewed all sunscreens, and feel these ones are effective.香蕉视频直播�

He adds that any sunscreen that is labelled as being specifically for children is a marketing thing, nothing more. 香蕉视频直播淭here香蕉视频直播檚 no such thing as sunscreen for children. There香蕉视频直播檚 no difference. The same sunscreen can be used by everyone in the family.香蕉视频直播�

Lui also cautions against buying spray-on sunscreen. 香蕉视频直播淪unscreen in a spray bottle is convenient, but it香蕉视频直播檚 very expensive, because you香蕉视频直播檙e just spraying a lot of it into the air.香蕉视频直播�

He adds that while some people get anxious about using sunscreen (香蕉视频直播淭hey worry about putting chemicals on their skin香蕉视频直播�), 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.

香蕉视频直播淚t香蕉视频直播檚 wiser to protect your skin than to avoid sunscreen.香蕉视频直播� He notes that sun greatly accelerates the aging process, and increases wrinkles later in life. 香蕉视频直播淚 tell people next time they香蕉视频直播檙e in front of a mirror to look at their face and then look at their bum. They香蕉视频直播檙e both the same age, but you don香蕉视频直播檛 get wrinkles on your bum, because it doesn香蕉视频直播檛 get exposed to the sun.香蕉视频直播�

Since the sun香蕉视频直播檚 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. 香蕉视频直播淚f you香蕉视频直播檙e a gardener, the nicest time to garden is early in the morning or in the evening. It香蕉视频直播檚 much safer and cooler.香蕉视频直播� Gardeners should wear a broad-brimmed hat with a brim as wide as their palm extending all around it. 香蕉视频直播淏aseball caps are cool, but they were designed to help a baseball player see better in sunlight, not protect him from the sun.香蕉视频直播�

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. 香蕉视频直播淪unlight helps make Vitamin D, but Vitamin D is also available through your diet or in supplements. And people think 香蕉视频直播業f some sun is good for Vitamin D, a lot of sun must be better.香蕉视频直播� 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.香蕉视频直播�

While some clothing is marketed as being designed to protect the skin from sun exposure, Lui says it香蕉视频直播檚 fine to buy less-expensive clothing that has a nice tight weave.

香蕉视频直播淭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.

香蕉视频直播淪imple things are fine. And common sense is the cheapest thing around.香蕉视频直播�
