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

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
