When Should We Protect Ourselves From The Sun
Essentially always. Follow this link if you are concerned about missing out on good sun
The severity of UV radiation is not the same as how hot the temperature is, or how bright the day is. There can be a lot of UV radiation on a very cloudy day or a cold day. Our senses cannot feel or detect UV. Because of this, we should check the UV index every day.
60% of the cancer-causing UV occurs between 10am 2pm, and we should be especially careful outside at that time all year round.
We should protect our skin whenever the UV index is 3 or greater.
The easiest advice is to simply follow the advice from the sunsmart app every day
And You Still Need Sunscreen
Since we have yet to find a magic pill that completely prevents sunburns and eliminates skin cancer risk, this is my plug for good old-fashioned sunscreen. Sunscreen has been shown to reduce both melanoma and squamous cell carcinoma. Randomized prospective studies in Australia showed that individuals who used daily sunscreen had a 50% reduction in melanoma and a 40% reduction in squamous cell carcinoma, compared to individuals who used sunscreen intermittently. So when the sun and warm weather beckon, remember to apply a broad-spectrum sunscreen with at least SPF 30 prior to going out in the sun, reapply every two hours, and apply liberally: 1 teaspoon to each arm, head and neck, front torso, and back and 2 teaspoons to each leg.
Whats The Best Sunscreen Brand To Buy
If its reef-safe sunscreen your after, you want to look for lotions that are biodegradable. Wirecutter studied the chemicals and tested several options, and determined Thinksport SPF 50+ Sunscreen has ingredients environmental scientists would approve of.
As a general sunscreen suggestion, Wirecutter also recommended Coppertone Ultra Guard Sunscreen Lotion SPF 70 as their favorite, but it contains reef-harming octinoxate.

The Importance Of Protecting Against Uv Light
Dr. Julie Sharp, head of health information at Cancer Research UK, notes that although sunscreen when applied properly can protect against UV radiation, people tend to think theyre invincible once they have put it on and spend longer in the sun. As a result, overall exposure to UV light is increased.
This research adds important evidence showing that sunscreen has a role, but that you shouldnt just rely on this to protect your skin, she adds. Its essential to get into good sun safety habits, whether at home or abroad, and take care not to burn sunburn is a clear sign that the DNA in your skin cells has been damaged and, over time, this can lead to skin cancer.
As well as applying generous amounts of sunscreen SPF 30 or higher when in the sun, the National Council on Skin Cancer Prevention recommend seeking shade when the sun is at its strongest and wearing sun-protective clothing, such as a wide-brimmed hat, wrap-on sunglasses and a T-shirt.
Medical News Today recently reported on a study published in the journal Cancer Epidemiology, Biomarkers & Prevention, which suggests that five or more blistering sunburns experienced before the age of 20 could increase the risk of melanoma by 80%.
How Much Sunscreen Should I Use
To get the full broad-spectrum protection out of your sunscreen, apply one ounce about a shot glass full to your entire body. Most people apply less than half of that amount, translating into reduced protection. Learn more.
With reapplication, a family of four should use one four-ounce bottle of sunscreen per person during a long day outdoors.

Study: Melanin Protects Us From Skin Cancer But Can Also Cause It
Think the risk of sun damage is over after you come indoors? Turns out, youre still susceptible to the risk of skin cancer long after youre exposed to UV radiation.
Think sunscreen is enough to protect you from skin cancer? Think again.
Researchers from Yale University have concluded that damage from the sun continues even after we are out of the sun or away from the tanning bed.
UVA radiation causes lesions or DNA damage to melanocytes, which are the skin cells that produce the skin pigment known as melanin.
Melanin is a protective pigment in skin, blocking UV radiation from damaging DNA and potentially causing skin cancer. Melanin does protect us, but this research shows it can also do us harm.
How Does Sunscreen Work To Protect Your Skin
Jason Richey
Rain or shine, winter or summer, any time spent outdoors leaves your delicate skin vulnerable to sun damage. Whether youre spending a summers day at your local pool, gliding down the slopes at your favorite ski resort, or simply sitting outside during your lunch break, its important to protect your skin with the right sun protection options.
Weve heard about the importance of applying sunscreen since childhood, but how does sunscreen work to protect our skin? Its simple to spray or slather on some SPF, but the science behind sunscreen protection is quite complex. In this guide, well take a look at the ways sun exposure affects skin based on a variety of factors, and help you determine which sunscreen options are best suited to your skin type and lifestyle.
How does sunscreen protect your skin? Lets find out.

How Melanin Can Hurt Us
Researchers say UV radiation generates reactive oxygen and nitrogen that energizes an electron in melanin.
That energy can cause DNA lesions, which can lead to cancer-causing mutations. The lesions typically appear less than one second after UV radiation exposure.
The researchers noted, however, that particular damage can also take place more than three hours after exposure to UVA radiation, which comes from the sun and from tanning beds.
You have two opposing things happening at the same time: Melanin protecting you and melanin damaging you, explained Dr. Doug E. Brash, a skin cancer researcher at the Yale School of Medicine. Youve got this race going on between melanin blocking and protecting you.
Brash said it is a simultaneous event melanin protects us at the same time sunlight is trying to damage our cells.
A consequence of these events is that melanin may be carcinogenic as well as protective against cancer, the new report stated.
We didnt see this coming, Brash added.
Who Should Use Sunscreen
The short answer is everyone! Men, women and children over 6 months of age should use sunscreen every day. This includes people who tan easily and those who dont remember, your skin is damaged by sun exposure over your lifetime, whether or not you burn.
Babies under the age of 6 months are the only exceptions their skin is highly sensitive. Stay out of the sun shade structures and sun-protective clothing are the best ways to safeguard infants.

Is Sunscreen Protecting You From Skin Cancer Or Causing You To Get It
People all around the world today depend on sunscreen to protect them and prevent skin cancer, as well as skin damage. Mainstream medical establishments and agencies repeatedly confirm that sunscreen use is vital during any sun exposure. But what if what you are being told is not the whole story? In fact, what if what you are being told is wrong? In this essay, we will examine the relationship between sunscreen and skin cancer, looking at all of its pros and cons.
When I was in my late teens/early 20s I used to work at a pharmacy in the dispensing area. As part of the experience, I had the opportunity to attend various workshops and seminars related to health from time to time. One particular time I was sent to a workshop about sunscreen products. I remember hearing everything that was shared and how sunscreen products must be recommended and taken seriously to protect everyone from skin cancer. I also remember thinking that something about this just did not make sense. The room was full of various white cream, chemical testers and my science-loving mind and background were in full swing thinking about the reaction between these chemicals on the skin and the sun.
What To Wear To Protect Your Skin From The Sun Did You Know That What You Wear Can Make A Big Difference When It Comes To Protecting Yourself From The Sun
Sunglasses are not just a fashion accessory they protect your eyes from damage by blocking UV rays. This is important for kids too! Look for the kind that have both UVA and UVB protection. The label might say UV 400 or 100% UV protection.
Look for clothing thats specially made to protect you from UV rays. The label shows the UV protection factor . UPF measures a fabrics ability to block UV rays from passing through and reaching the skin. The fabrics are classified into categories based on their UPF.
Like a sunscreens SPF, the higher the UPF, the less UV radiation reaches the skin and the better the protection. The fabrics used for this clothing are often lightweight, and some may be treated with ingredients to help them block UV rays. Look for UPF 15 or higher. UPF 50+ blocks most UV rays.

How Can I Tell If My Sunscreen Is Safe
Sunscreens manufactured and sold in the U.S. are regulated by the FDA. While the FDA doesnt usually test individual products, they do require manufacturers to use ingredients that are safe for human use, and they require products to list their ingredients on the label. The label will also identify where the product was made. Sunscreens made outside the U.S. may contain ingredients the FDA has not approved or has banned.
If youre concerned about the possible health effects of chemical ingredients that make their way into other body systems, you may feel safer using a physical sunscreen with ingredients like titanium dioxide and zinc oxide.
Does Sunscreen Cause Cancer
I dont know about you, but I read every ingredient on every product Im about to put on my skin. After all, our skin is the largest organ in our body, and science has long shown that what we put on our skin ends up in our bodies and quickly at that.
Many studies have demonstrated the effects of different sunscreens and how quickly the ingredients penetrate and absorb into the skin after application. One study, conducted in my home town at the Faculty of Pharmacy at the University of Manitoba, Canada, sought to develop a method for quantifying common sunscreen agents. Results revealed significant penetration of all sunscreen agents into the skin, meaning that all of these chemicals are entering our bloodstream, and as a result, entering multiple organs and cells within the body .
So, the next question becomes, are these ingredients that are entering our bloodstream particularly harmful? While much of the corporately-funded science that profits off the sales of sunscreen products says no, much of the unbiased research says yes.
The Food and Drug Administration hasnt reviewed the safety of these chemicals since the late 1970s. However, the Danish EPA concluded that after a careful review of the safety of active ingredients in sunscreen, most ingredients lacked information to ensure their safety . Sixteen of the 19 ingredients studied had no information about their potential to cause cancer.

Conversely People Can Develop Melanoma Without Going Out In The Sun At All
This could be due to exposure to UVA rays through windows in office buildings, which also tend to block vitamin D producing UVB light.
In fact, according to a study , Outdoor workers have a decreased risk of melanoma compared with indoor workers. That same study theorized that chronic sunlight exposure can have a protective effect.
Detection: Check Yourself Monthly
If you have a family history of skin cancer, you should examine your skin at least monthly for any changes. Check your entire body, even areas that are dont regularly get sun.
Normal moles are usually evenly colored, round or oval, and about the width of a pencil eraser . Most moles are harmless, but its important to notice any changes because this may mean a melanoma is developing.
The American Cancer Society advises using the ABCDE rule for assessing new blemishes:
- A is for Asymmetry: One half of a mole or birthmark does not match the other.
- B is for Border: The edges are irregular, ragged, notched, or blurred.
- C is for Color: The color is not the same all over and may include shades of brown or black, or sometimes with patches of pink, red, white, or blue.
- D is for Diameter: The spot is larger than 6 millimeters across , although melanomas can sometimes be smaller than this.
- E is for Evolving: The mole is changing in size, shape, or color.
For basal and squamous cell cancers look for new growths, spots, bumps, patches, or sores that dont heal after several weeks.
Contact your doctor immediately about any skin changes. Early detection makes all the difference for these easily treatable cancers.

Does Sunscreen Protect You From Skin Cancer
Unless you have been hiding out, possibly on the moon, for the last twenty years you know that getting too much sun can cause deadly melanoma cancer, which is why you should always put on sunscreen to protect yourself in the sun, right?
Actually, despite the conventional wisdom on the subject, this is not exactly true.
The fact is that sunscreen is often ineffective in preventing melanoma, and can often indirectly be the cause of cancer. Not only that, but getting the right kind of sun exposure can arguably prevent skin cancer!
So How Can You Get Safe Sun Exposure
One of the best ways of getting vitamin D is directly from the sun. It is important to get the right dose of sunlight, and not to overdo it.
If you are light-skinned, the right dose usually means staying in the sun until your skin has a pink tone, but avoiding sunburns.
With time, these multiple, short exposures will increase the melanin in your skin, giving you a tan. The tan, in turn, will naturally block UVA rays while allowing UVB rays to penetrate the skin and induce the production of protective vitamin D.
When my own family turns pink, we use this trick to ensure that our skin doesnt burn and instead turns into a nice tan.
Risk for melanoma cancer also depends, as briefly mentioned, on how far you are from the equator. There seems to be an increase in the effectiveness of sunscreen in reducing the risk of melanoma depending on how close one is to the equator. Sunscreen seems to be more effective for people who are closer to the equator.
But Id wager that for most people in the United States, sunscreen can put you more at risk for developing skin cancer. Thats because of our overexposure to UVA rays and our underexposure to UVB rays .

Science Validates The Use Of Sunscreen Saying It Protects The Skin From Cancers Like Melanoma
Sydney, July 19: Young adults who regularly use sunscreen reduce their risk of skin cancer by 40 per cent, a study has found. According to the World Health Organization , between two and three million non-melanoma skin cancers and 1,32,000 melanoma skin cancers occur each year globally.The global incidence of melanoma continues to increase, however, the main factors that predispose to the development of melanoma seem to be connected with recreational exposure to the sun and a history of sunburn. These factors lie within each individual’s own responsibility.
“The association of sun exposure and sunburn with melanoma risk, particularly in childhood, is well established and this study showed that regularly using sunscreen was protective against the harmful effects of sun exposure,” Xinhua news agency quoted lead researcher Anne Cust, Associate Professor at the University of Sydney in Australia, as saying. Cust noted that it is still difficult to get people to regularly apply sunscreen, and that likelihood to do so depended on a number of factors.
“Regular users of sunscreen were more likely to be female, younger, of British or northern European ancestry, and have higher education levels, lighter skin pigmentation, and a strong history of blistering sunburn,” Cust said.
“People were less likely to use sunscreen if they were male, older, less educated, or had skin that was darker or more resistant to sunburn.”
Does Sunscreen Actually Cause Skin Cancer
The Fear: Sunscreen doesnt protect us at all. It actually causes skin cancer!
In 2014, a scientific study from Sweden was widely reported as disproving the link between sun exposure and skin cancer. A number of sites used this report as a basis for arguing that rather than protecting us, sunscreen itself causes skin cancer.
This claim has circulated around the internet so much that the well-established fact-checking site Snopes.com actually has a page to set the record straight. The studys results are best summarized as, light-skinned Caucasian women living in parts of the world with limited sunshine and a low UV index would probably be better off with some sun exposure rather than no sun exposure.
This one study certainly does not overturn decades of established scientific fact: Sun exposure causes skin damage and may lead to skin cancer, and the more sun exposure you have, the higher your risk.

Is Sunscreen Safe To Use
There is clear evidence that regular use of sunscreens helps prevent skin cancer. Long-term studies of sunscreen use in Australia have found no harmful effects of regular use.
There have been questions raised about the safety of sunscreens that contain nanoparticles. The available evidence suggests that nanoparticles used in sunscreens do not pose a risk to health.
