The Sun Doesn't Cause Skin Cancer, But Sunscreen Does!

Summary

In this transcript, Andreas discusses the misconception that sunlight, particularly UVB rays, causes skin cancer. He argues that lack of sunlight and low vitamin D levels are more strongly linked to cancer, noting that people in sunny regions have lower skin cancer rates. He also criticizes the use of sunscreens, stating that they block UVB rays, prevent natural tanning, and contain harmful chemicals that could contribute to cancer. Andreas suggests gradual sun exposure for natural protection and advises against frequent soap use after sunbathing to retain vitamin D.

Takeaways

• ☀️ Sunlight is not the direct cause of skin cancer; in fact, lack of sunshine may contribute to its development.
• 🌞 UVB rays, previously thought to be a primary cause of skin cancer, are now believed not to be as harmful as UVA rays according to a new study.
• 🧴 Sunscreen use can lead to a false sense of security, potentially allowing more UVA rays to penetrate the skin without the body's natural warning signal of burning.
• 💊 Sunscreen ingredients can be harmful if ingested, yet they are applied to the skin and can be absorbed into the bloodstream, potentially overtaxing the liver.
• 🦴 Overuse of sunscreen can lead to vitamin D deficiency, which is linked to an increased risk of various types of cancer.
• 🌡 Regular, moderate sun exposure can help the body naturally produce a tan, which acts as a natural sunscreen and reduces the risk of skin damage.
• 🌍 Regions with high UV radiation, such as near the equator or high-altitude areas, do not have higher rates of skin cancer, suggesting other factors are at play.
• 🏙️ Areas with less sun exposure, like London, Norway, and Canada, have higher rates of skin cancer, possibly due to lower vitamin D levels.
• 🛁 Washing off sunscreen with soap can remove any vitamin D produced on the skin, which is essential for absorption and maintaining healthy skin.
• 🛡️ The body's natural bacteria on the skin are beneficial and should not be constantly killed off by frequent soap use, which can disrupt skin health.
• 🛑 It's important to balance sun exposure to avoid sunburn while still allowing the skin to produce vitamin D, which is crucial for overall health.

Q & A

What does Andreas claim about the relationship between sunlight and skin cancer?

Andreas argues that sunlight, specifically UVB, does not cause skin cancer. Instead, he suggests that lack of sunshine and vitamin D deficiency are linked to an increased risk of skin cancer.

According to the transcript, what is the new culprit in causing skin cancer instead of UVB?

The transcript mentions a new study that suggests UVA, not UVB, is now considered the culprit in causing skin cancer.

Why does Andreas believe that using sunscreen can be harmful?

Andreas believes that using sunscreen can be harmful because it may block UVB rays, leading to a lack of tanning and potentially more UVA penetration, which is now considered more harmful. Additionally, he mentions that sunscreens can cause vitamin D deficiency, which is linked to an increased cancer risk.

What is the role of tanning in sun exposure according to Andreas?

Andreas suggests that tanning acts as a natural protection for the skin against sun damage. It allows the body to stay out in the sun for longer periods without getting sunburned, which is harmful.

What is the connection between vitamin D levels and cancer risk as mentioned in the transcript?

The transcript states that having normal vitamin D levels can help prevent or reverse 77% of all cancers, according to a study from the University of California.

Why does Andreas recommend not washing the skin with soap after sun exposure?

Andreas advises against washing the skin with soap after sun exposure because it can remove the vitamin D that has been produced on the skin, which is essential for health and can stay on the skin for up to 48 hours before being absorbed by the body.

What are the potential health risks of the chemicals in sunscreens according to the transcript?

The transcript suggests that sunscreens contain chemicals and carcinogens that, if ingested, could be extremely dangerous. When applied to the skin, these chemicals can be absorbed into the bloodstream, potentially overtaxing the liver and leading to the development of intrahepatic gallstones and possibly skin cancer.

What is Andreas' view on the use of soap and its impact on the skin's health?

Andreas believes that using soap is unnecessary and can harm the skin by removing vital bacteria that keep the skin healthy and nourished, and by washing away the vitamin D produced on the skin.

How does Andreas describe the natural protection mechanism of the skin against sun exposure?

Andreas describes tanning as a natural protection mechanism of the skin against sun exposure, which allows for increased sun exposure without the risk of sunburn.

What does Andreas suggest about the correlation between sun exposure and skin cancer in regions with high UV radiation?

Andreas suggests that contrary to popular belief, regions with high UV radiation, such as near the equator or high altitude areas like the Swiss Alps, do not have higher rates of skin cancer. Instead, he points to regions with less sun exposure, like London, Norway, and Canada, as having higher rates of skin cancer.

What is the role of the liver in processing the chemicals from sunscreens as mentioned in the transcript?

The liver is responsible for breaking down the chemicals from sunscreens that are absorbed into the bloodstream. However, this process can overtax the liver and potentially lead to health issues.

🌞 Sunlight and Skin Cancer Myths Debunked

This paragraph discusses the common misconception that sunlight causes skin cancer, specifically UVB rays. The speaker argues that lack of sunshine, not the sun itself, is associated with skin cancer. They highlight a new study suggesting that UVA rays, not UVB, are the real culprit. The paragraph also addresses the use of sunscreens, which often block UVB, leading to increased UVA penetration without the protective signal of skin burning. The speaker emphasizes the importance of vitamin D for cancer prevention and suggests that sunscreens may actually contribute to vitamin D deficiency and skin cancer due to their chemical composition.

🧼 The Role of Soap in Vitamin D Absorption

The second paragraph focuses on the role of soap in the absorption of vitamin D and the maintenance of skin health. It advises against washing the skin with soap immediately after sun exposure, as vitamin D produced on the skin remains active for up to 48 hours. The speaker argues that soap is unnecessary for most of the body, except for areas not exposed to the sun, and that frequent use can strip the skin of beneficial bacteria that contribute to skin health. They also suggest that these bacteria help produce certain vitamins on the skin, making them essential for maintaining skin vitality.

Keywords

💡Sunlight

Sunlight is the natural light that comes from the sun and is vital for various biological processes on Earth, including photosynthesis and the production of vitamin D in humans. In the video, sunlight is discussed as a potential cause of skin cancer, but the speaker refutes this by stating that a lack of sunlight, not the sunlight itself, can lead to skin cancer.

💡Skin Cancer

Skin cancer is a type of cancer that arises from the skin cells. It is often linked to overexposure to ultraviolet (UV) radiation from the sun. The video script challenges the common belief that sunlight causes skin cancer, suggesting instead that lack of exposure to sunlight may be a factor.

💡UVB

UVB refers to a type of ultraviolet radiation with shorter wavelengths that can cause skin reddening and is traditionally considered a risk factor for skin cancer. The script mentions a new study that suggests UVB may not be the culprit for causing cancer, shifting the blame to UVA.

💡UVA

UVA is a type of ultraviolet radiation with longer wavelengths than UVB, which penetrates deeper into the skin and is now suggested in the script as a potential cause of skin cancer. The video discusses how sunscreens that block UVB but not UVA might be misleading in terms of skin protection.

💡Sunscreen

Sunscreen is a lotion or cream that is applied to the skin to protect it from the harmful effects of UV radiation. The video script discusses the potential downsides of sunscreen use, such as preventing the body from receiving the signal to tan and potentially leading to vitamin D deficiency.

💡Vitamin D

Vitamin D is an essential nutrient that is naturally produced in the skin upon exposure to sunlight. It plays a crucial role in maintaining bone health and immune function. The script emphasizes the importance of vitamin D in preventing various types of cancer and suggests that sunscreen use might lead to vitamin D deficiency.

💡Tanning

Tanning is the process by which the skin darkens due to exposure to UV radiation. The video argues that tanning is a natural protective response of the skin to sunlight and can be beneficial, contrary to the common belief that it is always harmful.

💡Vitamin D Deficiency

Vitamin D deficiency is a condition that occurs when the body does not have enough of the vitamin D hormone. The script suggests that using sunscreen can lead to vitamin D deficiency, which in turn increases the risk of various types of cancer.

💡Cancer Reversal

The term 'cancer reversal' in the script refers to the idea that maintaining normal levels of vitamin D can help prevent or even reverse certain types of cancer. It is mentioned that 77% of all cancers could potentially be avoided or reversed with adequate vitamin D levels.

💡Chemicals in Sunscreens

The script discusses the chemical composition of sunscreens, which can include dozens of chemicals, some of which are potentially carcinogenic. It raises concerns about the safety of these chemicals when applied to the skin and their potential absorption into the bloodstream.

💡Soap

Soap is a cleaning agent used to remove dirt and oils from the skin. The video script advises against using soap after sun exposure, as it can wash away the vitamin D produced on the skin and potentially remove beneficial bacteria that contribute to skin health.

Highlights

Contrary to popular belief, lack of sunshine, not sunlight, may cause skin cancer.

Many skin cancers occur in areas not exposed to the sun.

A new study suggests that UVB does not cause cancer, but UVA might.

Sunscreen that only blocks UVB can lead to skin burning and increased UVA penetration.

Using sunscreen can result in vitamin D deficiency, which raises cancer risk.

77% of cancers can be prevented or reversed with normal vitamin D levels, according to a study from Creighton University.

The body signals when too much sun exposure is received, such as skin reddening.

Tanning is a natural protection mechanism against sun damage.

People living in areas with high UV radiation, like the equator, do not have higher rates of skin cancer.

Countries with low sun exposure, such as London, have higher skin cancer rates.

Sunscreens contain chemicals that could be considered dangerous if ingested.

Chemicals in sunscreens are absorbed by the skin and can overburden the liver.

Sunscreen use may be a leading cause of skin cancer due to chemical absorption.

Washing sunscreen off with soap can remove vitamin D produced on the skin.

Vitamin D produced from sun exposure remains on the skin for up to 48 hours and should not be immediately washed off.

Soap is not necessary for washing most of the skin and can harm beneficial bacteria.

Transcripts

Andreas we've been told that the sun

will give sunlight will give us cancer

skin cancer yes and you say that's

absolutely not true that no there is no

proof here to that effect in fact here

it's the opposite that lack of sunshine

causes skin cancer um you may know that

many people have skin cancers in areas

that are never even exposed to the sun

that's true and so it's not the Sun the

the UVB is now you know take taken off

the hook it's no longer at the culprit

there's a brand new study just came out

and it showed that UVB doesn't cause the

cancer it's the UVA now when you use

sunscreens and are many sunscreens that

just block out UVB so you don't tan you

you basically right burn so that you

don't burn your skin um skin burning is

not a good idea you in any case you

don't want to burn your skin so

typically if your body is uh in the sun

too long it will start burning you you

would want to get out of it whereas if

you put suntan lotion on you don't get

that signal and you allow a lot of

penetration of UVA now there are some of

these other you know screens you know

that are blocking out both UVA and ubb

and you think oh now I'm safe right yes

but you are becoming vitamin D deficient

while being in the sun and if you are

vitamin D vitamin D defis your your

cancer risk goes right up okay so again

cancer any kind of cancer so you you

need your Vitamin D in order to be

cancer free so 77% of all cancers can be

reversed or you avoided by having normal

vitamin D levels according to cron

University study okay so you shouldn't

get sunburn you should avoid that but if

you're not wearing sunscreen your body

will tell you if you're getting too much

yes the body will you know once your

skin starts rening that's the time to go

out but after regular if you start

increasing your sun exposure near little

by little you will have a natural

protection on the skin which is called

tanning yes and then you can stay out in

the sun your hours I lived in Cypress

for 15 years it's a very it's 300 near

30 days sunlight very bright sunlight

very warm I could stay out in the sun

all day long and would never have any

sunburn or any damage to the skin it's

the best sunscreen is a good tan yes and

again the the people in the in the

countries where they have the highest UV

radiation um that is the equator you the

countries in the near the equator or the

High Altitude the Swiss Alpine mountains

or the German Alps you have you have

400% more exposure to UV radiation they

don't have any skin cancers in those

places none no the the places that have

the most are places like London uh in

England very little sun exposure uh the

Northern Plains Norway um you Denmark uh

Finland uh Scotland the most and uh

Canada and Canada so the least where

people have low vitamin D levels not

enough sun exposure during the winter

month that's often when they have the

outbreaks but we can actually harm our

skin by using sunscreens definitely

sunscreens are they are composed of

sometimes dozens of of chemicals

carcinogens that are normally if you put

that in the food let's say if a pro food

process Processing Company like your

healthy choice or whatever would put

that in the food they would lose their

license and the owners would be

imprisoned because it's extremely

dangerous to put that in the food but

you're allowed to put it on the skin

where is it going after an hour you put

some more on it because it's gone you

absorb more most of that stuff these

chemicals are highly absorbable they

enter the bloodstream and where do they

go they go to the liver and then the

liver has to you break them down but

that over taxes the liver you make what

you you may go into that producing a lot

of intrahepatic gold stones and some of

them accumulate in the tissues in the

connective tissues and if they happen to

be in the skin area under the skin and

they saturate there you may develop skin

cancer because you took the sunscreens

so sunscreens are now a leading cause of

skin cancer because people are

slathering it on sling it on their skin

and they absorb that stuff and then the

other problem that happens they wash off

their that stuff with soap so they soap

the whole body afterwards to get it off

and with it they get rid of all the

vitamin D that incident or accidentally

may have been created on the skin when

you use soap after to sunbathing let's

say even without sunscreens you know if

you just you know make vitamin D make

sure you don't use soap to wash your

skin except under the arms and in the

genital area where the sun doesn't go

anywhere and vitamin D is not made uh

you don't want to wash it off because

the the vitamin D stays on your skin for

up to 48 hours and gradually is absorbed

and that's how you are building it in

the body so you don't want to wash it

off not right away soap not right away

way okay so soap is not necessary anyway

I've not used soap

um except when you have make your hands

dirty with oil or something else so you

don't want to you diminish your skin of

the vital bacteria that live there that

reside there that keep the skin healthy

and nourished and produce certain you

vitamins actually on the skin so the

bacteria are best friends you don't want

to kill them off all the time for
