I wonder if the SG military teaches our boys to wear sunscreen every day? They must be exposed to harmful UV radiation everyday (face, body and esp the head!). If the men get good education on sun protection during NS, I believe we will see a lot more men wearing sun screen in Singapore for a lifetime.
Our "sunscreen" comes in black/green 😂
tbh i dont even wear sunscreen let alone barely drink during heatwaves idk why maybe my body is immune to the heat i guess
I used to wear sunscreen during BMT I got mock as Sgt view it as comfort items lol
@@limyongquan1998that’s so messed up, sunscreen is a necessity with how dangerous the sun can be during the afternoon hours
Even in SKorea’s military, using sunscreen is highly encouraged.
Need to clarify some things here because some content is quite misleading.
Firstly, the UV camera does not always identify who is wearing sunscreen or not. Nor does it measure UV A/B protection effectiveness (i.e SPF). It only shows you whether your skin or the product on your skin such as sunscreen has any interaction with the UV rays. This means in effect, it is ONLY helpful to show you whether you missed any spots with your sunscreen or other UV-protection method.
You will realise this if you pay attention to the very very melanated skin of the darker persons in the video, which were almost the same as DIana's sunscreen. They did not wear sunscreen and most of the time, highly melanated people (dark skinned people) will show up in UV cameras like that.
How UV cameras like the ones in the video work is that photons of UVA are sent out from the camera, and then it measures how well the substance or item absorbs the light, and then sends it back as visible light (called fluorescence). That's why skin with the product that absorbs UV rays looks dark, the same way dark skin will also look the same (and the difference can be seen versus someone lighter skinned without sunscreen). Human skin tends to naturally reflect light and scatters it around, so skin without some protective barrier like sunscreen won't look very dark.
Anyway it doesn't mean dark skinned (known as melanated) people don't need sunscreen. EVERYONE needs sunscreen, or SOME form of UV protection. It doesn't have to be something you specifically slather on your face -- sometimes there are UV-blocking compounds in some moisturisers, face creams, very commonly in liquid, cream or powder foundations (although powder UV is questionable).
You can also opt to directly shield your entire exposed skin by wearing clothes that absorb and protect your skin from UV rays (they are made specially for that, or contain compounds that can achieve that), this is common in swimwear, or, you can use an umbrella, hat, poncho, etc, such as the one shown in the video.
But black or darker clothing absorbs heat (light) a lot and can make you feel much warmer. So if you're looking for UV-reflecting garments, get lighter colours such as white or silver as they reflect heat AWAY from you better. It's something the video did not tell you, but you should also be aware of this because there's no point getting 100% UV blocking but then you feel insanely warm and sweaty inside, especially in humid Singapore.
Also, just because the sky is overcast doesn't mean you don't get exposed to UV rays. It's still there, and as long as you hit sunlight, you will get UV exposure. Not all UV exposure is bad - we need SOME of it every day, but from at least 5 minutes (without sunscreen) and no longer than 15 minutes (can be 30 minutes for dark skinned people).

Your post is very informative & useful. Appreciate the facts ❤
The UV camera does not show the effectiveness of your sunscreen, rather it only shows if you have sufficient coverage or perhaps missed a spot
But isn’t wearing it better than going out with naked skin?
Actually, you forgot about one more potential damage UV rays can cause: Cataracts in the eye
how do people prevent this tho?
@@joshuaseah1695UV protection sunglasses
yup.. tat's why my family doc has advice me to put on UV protection sunglasses
Putting sunscreen will actually make your skin not age so fast. If you want to look younger in older age.
Actually… Just normal clothing, especially a slightly thicker cloth, will block a good amount of UV rays. No need to purposely buy SPF clothing… Why didn’t they measure that?
Thank you CNA Insider! Love this ep!
Feel a bit irresponsible to talk about UV but exclude the other side of the coin -- it is vital for Vitamin D-generation, which the deficiency has been linked to so many health issues. I think the conundrum is how to get a safe or balanced intake of UV instead blocking it entirely. That would be a better approach of the topic in my opinion.
It is safer to avoid the sun and take Vit D supplements. This is advice from doctors, btw.
Please. You don't need sun for vitamin d. You can take it by supplements. Also, applying sunblock is not 100%> you still need some physical block too even with sunblock on.
2:22 are our face the same? bruh 😂😂😂😂
The ads I got during YT ad break are sunscreen ads 😂
I use ads block sometime YT block me
Good to know that apparels can block off UV effectively. But will they lost the effect after a few washes?
Woah I actively wear sunscreen but not cap. I did not know the head can get sunburn despite having hair. Will wear my cap more often from now one
There should also be an episode of Vitamin D deficiency. The reason why kids nowadays are getting myopia younger and younger is actually due to Vitamin D deficiency and not because of too much screens/computers. And you may think, "Just take Vitamin D supplements!" But scientific research shows us that supplementation affects us (even plants!!) differently compared to real sunlight, which is heaps better for the processes within our body. Of course, too much sunlight poses risks too. So everything should be in moderation. I have been super fearful of sun since I was like 20 years old, always put on sunblock even indoors, and recently found out I am Vitamin D deficient.
Myopia is due to insufficient outdoor activities to allow the lens in the eyes to accommodate to distant objects. Myopia is NOT due to deficiency of vitamin D, do not confuse correlation with causation!
I would love a content about vitamin d too. According to some Taiwan health show the doctors said we only need 15 to 20 mins under the sun each day to get enough vitamin d.
Not sure if it's true but i only get sun exposure when i go out to buy lunch at 2 or 3pm.
@@LittleStrawbirdy you're only putting sunscreen at your face and neck ,a small percentage of your total skin.You still have your hands ,arms ,back , legs not covered by sunscreen. Also , you only need 10 minutes of sun light three times a week to meet your vit d requirements.Its unlikely you sunblock is the caused of your vit d deficiency
Drink more milk and eat more yogurt would do the trick for you.
@@leeheemeng3799not true. Small amounts of skin exposed may not get you the required amount of Vit D. To optimise Vit D production, people have to lay down horizontally topless (or near topless lol) so that the exposed parts get UVB more evenly. If you're just walking in the sun, you get very little. You can Google about high rates of Muslim women being deficient in Vitamin D cos they're always all covered up.
And btw for years I was avoiding sun exposure and covering up also, not just putting on sunblock.
Does the UV light we used when doing gel manicure cause skin damage as well? Does that mean we have to put sunscreen on our fingers before doing gel manicure?
Wonder if they will do one on PFAS as major countries have all started to regulate it in food and water.
Yes, CNA please do pfas especially in food (read coffee, free-range eggs and rice have pfas)
She should wear them on exposed areas like her neck décolletage and her hands and not just on the face.
To test for skin cancer we need skin biopsy which is cut a portion of our skin to send to lab for test.
The follow-up question on clothing is then how does 2 shirts of equal 'lightness' in materials compare, one being marketed with UPF and another without?
Not really, sunscreen was always important. Australia for example classify them as a medical item
Topic miss out... does the "UV protection clothes" get "washed out" after years of using like washing them ?
yes actually! But not to a worrisome amount, and will vary by brand. There’s people who buy those at home UV readers and do their own tests by running new pieces of uv clothing through the wash cycle like 10 times to see how much protection wears off after a few washes. I didn’t save any links but 抖音 has a lot of these vlogs
Reapply sunblock with clean hands, if not use sunblock sticks. Sunblock spray will be blown away by the winds, unless spray on the hand palm then apply. Also, tinted sunblock protect against bluelight which the sun omit out. Which creates freckles, melasma etc.
How do you talk about UV exposure through windows without talking about window tint? I have window tint on all my windows at home without sacrificing visibility as opposed to the frosted glass they used in this show yet still have a 99.9% UV block. Not to mention I have tint on most of my car windows and even the front side windows have 3M crystalline 90 tints for a legal 72% VLT while still having 99.9% UV protection. I wish they covered window tint just so I know if tint manufacturer claims are accurate.
PE classes for all teachers and students better start only after all have applied sunblock! 🙏🙏
How did our grandparents or great grandparents survive back then without sunscreen?
Without UV, are we going to get enough vitamin D?
Sunblock doesn't block 100% of the UV. And most people only need 5, 10 min of sunlight to produce Vitamin D
I think if you spend the majority of the time indoors and only outside for not much time you do not need sunscreen. People actually need sunlight on the skin to remain healthy. Can look up new studies on how getting enough sun is important for immunity.
An impressive video. I didn't know darker clothing protects the skin better.
All the Aunties and Uncles should watch this. My parents don't believe in sunblock no matter how many times I tell them. And the fact that you have to protect your scalp from the sun is also an important information that's commonly ignored. The video should say that you'll loose hair faster without proper protection, I guarantee more people will take it to heart then.
I would think uv causes balding.
The closer you are to the equator, the more short wave (cancer causing) UV dosage you'll get. The best advice for those people is to stay indoors.
Not very helpful for many people! What about the farmers or builders? People who work outdoors? Or the poor?
Immigrant problems
We live in Canada and this time of year our days are 18 hours long it's very easy to get a sunburn. Here's a neat fact sunburn/radiation burn are very hard to tell apart.
Now i just want to know where to get the thick sunscreen patch 😂
Shopee. Korean brand.
Diana is getting hotter
Must be the sun 😂👍🏼
There’s a reason why people native to the equator have dark skin
The is the most fun & educated spf video ❤
Best to put on hat and long sleeves or simply walk under shelter when transiting. Don't apply chemicals onto your skin.
At 6:30PM, Singapore's UV radiation was at 26% rather than 7-10% according to this scale.
0-50%: manageable, no need for sunblock, stay vigilant.
50-65%: still normal, will generally not cause damage to skin.
65-75%: elevated, need sunblock.
75-85%: high, healthy people may get skin cancer if exposed to the sun for more than a few hours without any sunblock.
85-100%: very high, stay indoors from 10:30 AM to 3:30 PM.
100-120%: hazardous, stay indoors whenever possible.
Then at 4:00PM, it is at 91-104%.
I have the resources to wear sunscreen but I too lazy, unless I go to East Coast Park or some random parks.
So scared don’t go out la! Last time people were got sunscreen 😂!
Is it better to go down to details in terms of hours? Like 8am to 10am no sun screen required etc.
Would be better to test the sunscreen applied. Lab test results use a thick layer of sunblock. Also, smooth concrete pavements reflect UV towards you and umbrella wont even help
I only wear sunscreen from 5pm onwards, 5 days a week, during my intense running workout.
Are you staying indoors before 5pm?
So it make sense to use UV umbrella in sunny day.
No discussion about the risks from the chemicals in sunscreens and the other products?
Yes! This always worried me. 60% of what we put on our skin is absorbed through it.
Exactly, as a medical professional who has seen autoimmune diseases and cancers skyrocketed in rich countries with all the bourgeois chemical-skincare products.
The best solution is physical protection- umbrella, hat and long sleeves, scarfs… etc
Oh… imagine putting all these chemicals on babies and children. Yikes !!
Stop fearmongering. Everything is a chemical. Water is a chemical. Be specific about the chemical you want to demonise and cry bloody murder about. Show your evidence as well. If you don't similarly demonise and question the safety of the food you eat and the water you splash on your face, then don't be a hypocrite and question this specifically because you don't know how to read and understand scientific literature or distrust science communicators because feelings and fearmongering.
If you use a well-regulated and tested sunscreen, you should be safe. It's the sunscreens from countries that do not impose rigorous and thorough testing that may pose risks. And it's not the chemical sunscreen ingredient itself that's the risk -- it's the other ingredients that are inside.
Australia treats sunscreen as MEDICAL DEVICES. Not cosmetics. This means any sunscreen sold there with SPF claims must undergo rigorous testing for safety and efficacy before being able to be sold with that guarantee.
Singapore should step up testing for sunscreens the same way as well.
The risks are minimal compared to UV radiation and skin cancer. You can use INCI decoder to check the ingredients. If you are really worried, can also use physical sunscreen, but I personally prefer chemical due to it's spreadability and other benefits
People don't think their auto glasses, I guess, not in Singapore. :)
Great content. I really hope more singaporean can wear sunscreen dally and reapply it.
Please do more more such beneficial content
I wonder, does UV blocking film works. It's supposed to block 99.9%
9:18 what is she doing?
Omg love this wanted to hear about uv
What about makeup with sunscreen and large hats that gave 50spf blocking. The chemicals in screen outweigh protection as a lot of them are endocrine disrupters .
Cost of sunscreen cream needs to be taken into account.
Would you rather get skin cancer?
do you think buying like $20 of sunscreen monthly is expensive, compared to 5-6 figure of cancer treatment, the difficult process you have to go through? Consider the health risks you get if it is "cheaper" than using sunscreen daily.
Well said!👍
UV protection is for the privileged. Why not tell MOM to make it compulsory for employers to provide sunscreen for those workers working under the sun. It is also overrated. It’s not that easy to be physically affected by UV especially in Singapore where people don’t go out to the sun much and are sheltered everywhere.
Does wearing masks protect against UV rays?
Probably black colour one
Where are the UV? It had been raining every single day almost without fail!
UV comes from the sun,rain doesnt make the sun disappear so there still UV during rain or cloudy weather
@@leeheemeng3799nowhere near harmful levels during a bright sunny day
what's the brand of the sunscreen she's using?
ANESSA Perfect UV Sunscreen Skincare Spray SPF50+ PA++++
The new packaging has that iconic teal blue nozzle. hahaha.
We're Not #CaucAsian We're #Asian 2:22 And We Have #Melanin #YellowSkin #MelaninSkin #AsianSkin 2:22
this video is half-baked...
so the question is... prolonged daily usage of these SUNBLOCK (CHEMICALS) on our skin, what are the negative health effects???
p.s. our ancestors... technically before the birth of sunscreen... did not suffer from UV Skin Cancer....
...and you only applied it on your face? other parts of your body are not affected by the UV rays ah (neck, back of ears, etc?)
It surprises me on how many parents do not consider sun protection to be an important aspect for their children. With a "higher educated" working generation, and yet so many adults do not take sun damage seriously.
You as do need vitamin d and a lot is Asians are deficient because they are indoor a lot more and this not only affects vitamin levels but there eye site as they have extreme myopia and it’s so bad that done are legally blind. You need two hours of sunlight per day to keep eyeballs from elongating.
It's so interesting seeing the difference in the comments section. If this was in the US the comments section would be full of people saying how it's all a lie and UV isn't dangerous LMAO.
Does the clothes lose its uv protection overtime after more washes? Haaa i wish there was a q&a session
Patrick should have the least amount od UV damage. what a Starfish
Tell people UV causeS wrinkle , then people will wear sunscreen haha. Because that is me 😂
UV rays are good for human skin.
Maybe the first 10 minutes a day but if you work outside it's not. Yes I have skin cancer, Luckily it's only Basel cell so it's very treatable but I have to be careful. I have scares all over my arms/face from where it has been cut out.
It would be interesting to remind where Singapore stands on UV exposure, compared to other places.
It is sure near the equator and gets important daily doses of sunlight all years long, but humidity makes the sky not always bright blue.
In drier areas, such as the Mediterranean, it feels like with that deep blue sky, UVs come 'unfiltered'. Not even mentioning southern Australia where on top of that you can have the thinner ozone layer letting even more UV through...
Can anyone recommend me non greasy sunscreen?
I like the biore uv aqua rich! it's very spreadable and doesn't have much oily feel
i second Biore UV Aqua rich. Affordable and the only sunscreen ill ever use for face because it's non sticky and doesn't leave a white cast. Goes on like a gel, feels thin and non-greasy.
Anessa is the best
The video ends with the host recommending that people wear sunscreen, sunglasses, hats, and UPF clothing whenever they are outdoors.
recommendations, learn from the chinese in China, they really cover head to toe, very exaggerated lol.
1. Sunscreen - anessa japanese brand available everywhere donki, watsons
2. uv cover clothes best brands are Beneunder, ohsunny.
Or they can go back China where there is less sun
B/c sunblock are not 100% you still need physical to block it as well. If not, will cause saggy skin, freckles etc. decreases collagen. Need to stay youthful to fish for men hehe. They just love youthful to maintain the freshness. Hehe. Body inner need nourishment some when xx they feel good lol😂
Does the sunscreen and the UV clothes block vitamin D?
yes you need uv-b rays for that
Sunnies next.
I wear Muslim hijab covering my head daily means my scalp is protected from UV and also prevent scalp sunburn too ya? :)
Stay at home. NO PROBLEM.😂😂😂😂
First uv
Soon there will be a video on how deadly the air outside..
Then how many germs are outside on the lift door buttons and toilet.
Then you end up . Going out.. with Sunglasses, Hat, sunscreen.. Face Mask, Long sleeves, Hand gloves..
And hand sanitizer every 10 mins..
Wiping your fork and spoons before eating.
Let's not be too overly paranoid..then we will be measuring the food sugars levels.. cleanliness of utensils.. etc .. we are all dying..when we go outside..
Bass on your thinking then you should not be watching cna. 😂 Feel free to skip the sunscreen if that's your choice. Hope u won't regret after another 10 years of sun exposure 😂
Sunscreen is the cheapest beauty product anyone can afford. If apply sunscreen daily you will look good and much younger than your age. I am 30s but i got people thinking i am students 😂
@@celestialstar124same, people keep thinking I'm 10+ years younger than I actually am
We all die, but unlike you, we don't want to be saddled with expensive cancer treatments and live in pain every day until we die from preventable diseases. You want to expose yourself to environmental risks then your pasal lah. Don't need to mock others who want to die peacefully lol
Welcome to my world of skin cancer. If it doesn't kill you you will have a ton of scares where it has been cut out. Bob Marley died from skin cancer at a young age.
😢😅All thanks to climate change. UV sunscreen 🧴 price will skyrocket...😡😡😡
The increase in UV is caused by CFCs eating away at the ozone layer, Not by climate change. In Canada where I live sunscreen is cheap.
UV sunscreen are very budget friendly. Too many brands to choose. Etc. Even with climate changes. Stop worrying the unnecessary.
Look at some really handsome actors who didn't use sunscreen. Now they age so poorly while those who use sunscreen looks alot younger for their age. 😂
A lot of jobs.. dun allow it.. tell that to police officers, the fire fighters, the army soldiers, the health workers, the construction workers, the NParks workers..etc..
Lol i am aware of so many health care workers wearing sunscreen. Lol police also got wear sunscreen that I know of.
Feels like you didn't actually ask these people you talked about
Sunscreens don’t last the whole day, only 2hrs at best. Nothing gonna beat long sleeved clothing
Really? They explicitly disallow sunscreen in these occupations? CNA needs to cover this piece of news. Sounds shocking.
If more singaporean uses sunscreen we can pass better looking genes to our future generation. 😂
True true!!! I agree with you. Right now, the coolie genes inherited by the majority of Singaporeans from their ancestors are physically undesirable.
I dont think it works that way
Or you can have babies with people with better UV tolerating skin because your so called better looking sunscreen needing genes not gonna last
Science has just been reinvented.
Troglodyte doesn’t know how genes work
Sunscreen ad for sure.
Well, you guys also say that smoking cannabis puts me in extreme danger, so why the hell should I listen to you about UV rays when you're still spreading misinformation about a plant?
Bob Marley died from skin cancer at a young age.
@@MHdollrevievs And so do tons of young people that have never smoked cannabis, what's your point? Can you link any studies done that show a correlation between cannabis use and skin cancer? No of course you can't, because there aren't any. Maybe the dude spent a ton of time in the sun, he was from Jamaica and spent tons of time outdoors after all....
Blah Blah Blah
