Light Guide
Different Types of Light and how they effect us:
Vision is our most dominant sense. If you remove all other senses, you can live
effectively with sight alone. However, remove vision and your life becomes
very hard. The occipital lobe, i.e. the back of your brain, is responsible for
processing what you see. We see things because our eyes receive light and
make sense of it. If you see something, like the desk your computer is on, the
walls, the windows, the floor, or your hands, it is because the light reflects from
those things and into your eyes.
Before we invented light sources, light came from the sun, volcanoes,
stars, natural phenomena, and biochemical processes (a.k.a. fire.) Naturally,
only two of these light sources matter. Sunlight is the absolute most
predominant light source, while fire takes a distant second place. This might
seem surprising to you, but hear me out. We have been evolving for millions of
years. The trials and tribulations of our hairy ancestors shape how we are
supposed to live today. Homo sapiens as a species have existed for 200 000 -
300 000 years. With all this in mind, realize that evidence for widespread,
controlled, use of fire dates back 125 000 years ago. First of all, humans have
lived without the use of fire for the majority of their existence. Second, the
usage of fire during our evolution was very minimal. If we set the start of our
evolution at three million years ago (beginning of the homo genus), fire has only
seen widespread use through 0.4% of it. From an order of importance regarding
health, the sun is 99.6% dominant from a light source perspective.
However, today artificial lights dominate society. The first widespread
use of artificial lights came at the end of the 19th century when Thomas Edison
invented and commercialized functional lightbulbs. This ultimately means that
artificial light has been around for 0.005% of our evolution and 0.05% of human
existence on Earth. If you look around, you will see children playing on iPads,
teenagers and adults alike glued to their phones, indoor lighting that makes you
blind, and rampant insomnia.
Insomnia is another word for consistently having difficulties sleeping.
One of the reasons why it is rampant in modern society is because of artificial
light. Light is important because it is one of the factors that regulate a system
called the circadian rhythm. The circadian rhythm is the sleep-wake cycle. It
repeats approximately every 24 hours. As you wake up in the morning, cortisol
increases. Cortisol is the hormone that is associated with being awake. As
everything becomes darker, your body realizes it is nighttime, and the secretion
the sleep hormone melatonin starts.
Different types of light affect you in different ways. Blue light, the
primary light emitted by screens and ordinary household lights, increases
cortisol. Red light does not. Sitting around a campfire will thus not affect your
internal clock, while screens will. The reason for this is that in the morning, the
sun partially emits blue light. In the evening, it primarily emits red light. If you
walk later in the day, sunlight is generally more golden. Next time you are
outside, consider the golden hours as visual proof of the sun emitting more red
light the closer it gets to sunset. Because we have evolved with the sun, blue
light says wake up while red light says relax.
When we sit on our phones at night, our bodies switch to daytime mode.
You get energized. Again, most cases of insomnia come from exposure to too
much blue light. So this thread is about making the sun your primary light source. We have evolved with the sun and not with artificial
light. Referring to Evolution: the more your environment
resembles that of a hunter-gatherer, the more healthy you will be.
When it comes to insomnia, blue light exposure is not the end of the
story. Light strength is even more important. The most significant shift we go
through regarding sleep happens right after the sun sets. It gets dark. In addition
to avoiding blue light exposure a few hours before bed, you should expose
yourself to darkness. Nothing, except a hit to the head, makes you fall asleep
faster than darkness.
Quick tip for those who want to do things in their house when it is dark:
replace all light bulbs with near-infrared lights. Alternatively, you can wear blue
light-filtering glasses. Doing so ensures that the light you expose yourself to
does not trick your mind into believing it is daytime. They will also provide
darkness since part of the color spectrum gets blocked. I also recommend using
blue light filters on your electronic devices. F.lux is the one I use on my
computer. On Android devices, an app called Twilight allows you to make your
screen red. On Apple phones, you can go to Settings > Accessibility > Display &
Text Size > Colour Filters. Turn Colour Filters on and turn it up to the max.
Importance of the Sun
All things are energy. Among the things of the world, there are living beings.
Living beings require a constant flow of energy. This energy must continuously
enter and exit them at all times. If it stops doing so, these beings are proclaimed
dead.
The big question is: where does energy come from? I have no idea about
the universal source of energy. However, the energy source of planet Earth is
the sun. Without the sun there would be no nature, food, or you. The energy
that is currently sustaining you comes from the sun. The entire food chain
depends on the sun. All advanced organisms, with some exceptions, are
dependent on the sun. Yet there are health organizations and experts who tell
us that the sun is dangerous.
There is a doctor called Jack Kruse. He views light as the absolute root of
health, and rightfully so. While I like to stay with evolution, he emphasizes
what enabled evolution to occur in the first place.Since we
have been exposed to the sun during our evolution, sun exposure must be
essential to human health. There is no way around it. Sunlight regulates our
circadian rhythm through skin and eye exposure. Exposure to the sun is the
only way of creating cholecalciferol, i.e. vitamin D3. You do not need 50
peer-reviewed meta-analyses to understand that sun exposure is vital. You only
need the two facts I just stated.
The sun is something in our environment and should be treated as
such. Prolonged sun exposure will damage your skin, just like cold exposure
will create cellular damage. The same goes for heat, food, sex, or anything else
Humans can influence. Modern science overplays the dangerous effects of
sunlight because most modern human beings have poor skin health.
Weak skin will not tolerate the sun. When people switch to a healthier way of living, they
usually experience an increased tolerance to sun exposure.
Vitamin D3 and Sunbathing
Being out in the sun and getting Vitamin D3 might sound simple, but it is much
more complicated than you might think. First, we need to know how sunlight
leads to Vitamin D3 production in the skin. There is a molecule in your skin
called 7-dehydrocholesterol. Electromagnetic energy in the form of medium
wavelength ultraviolet rays (UVB) turns 7-dehydrocholesterol to previtamin D3
when it hits our skin. A subsequent reaction turns previtamin D3 into
cholecalciferol (Vitamin D3). The liver then turns cholecalciferol into calcidiol.
Lastly, the kidneys turn calcidiol into calcitriol. According to our current
scientific understanding, calcitriol is the molecule that does the stuff we
attribute to vitamin D3. Using this information, we can make a series of helpful
conclusions:
1. Cholesterol is needed for vitamin D3 production because
7-dehydrocholesterol is what turns into vitamin D3. Getting enough
unprocessed cholesterol in your diet is thus a good idea. If you do not
consume dietary cholesterol and saturated fat, you will rely on your liver
to create something that every cell in your body requires.
2. UVB radiation is what allows us to create Vitamin D3. Sunscreen does
not only contain toxic ingredients, it also blocks UVB radiation from
penetrating your skin. If you wear sunscreen, you will not obtain vitamin
D3.
3. The amount of UV radiation the sun emits varies depending on the time
of the day. The more natural UV radiation you are exposed to, the more
Vitamin D3 you will create per minute. Therefore, you want to sunbathe
when the UV radiation is at a high level. Otherwise, you will not be
getting a lot of vitamin D3.
4. Exposing your hands and face to the sun is not enough. Expose as much
of your body as possible to the sun if good vitamin D3 levels are your
Goal. In an article published in the journal Journal of Preventive Medicine & Public
Health, Dimitrios T. Papadimitriou shows how the daily recommended intake
for vitamin D3 should be 10-20 times higher than what we use today. They
tell us that we need 400 - 800 IU of vitamin D3. However, the RDA should be
somewhere between 8000 - 10 000 IU. To get this amount, you need to follow
the four points above. The darker your skin is, the more time you need to
spend in the sun. Paler individuals will acquire the amount of vitamin D3 they
need much faster than darker individuals.
Summary
Avoid artificial light sources and expose yourself to sunlight. We are not
accustomed to artificial lighting because we have evolved with sunlight. Always
use blue light filters on your electronic devices. Your indoor lighting should be
warm. Alternatively, use blue light filtering glasses indoors when it becomes
dark outside. You need the sun to regulate the circadian rhythm and to make
Vitamin D3. Do not fear UV radiation—without it, you cannot make Vitamin
D3.

good shit man, rais awareness on that toxic sunscreen people think will prevent them from aging xD its literally 99% diet and the rest is getting out of the sun as soon as you feel burned yourself, which is when you would want to get out of the sun naturally.
