It’s a question that's been pondered for centuries. It's such an obvious question, in fact, that it barely even seems worth asking anymore. But it is worth asking! And the answer is actually pretty interesting. So let's get into it!
The quick and simple answer is that blood absorbs green light and reflects red light. As a result, it appears red to your eye.
This means that the reason why the blood looks red is because of how light is reflected through our body!

Blood is red because of hemoglobin, a protein molecule that contains iron. When the oxygen in your blood comes in contact with this iron and binds to it, it gives off a reddish color.
Hemoglobin helps transport oxygen throughout the body through arteries and veins. Hemoglobin is what gives blood its dark red color. Red light can't pass through a water molecule because of its electric charge, but green light can: it reflects off the surface of water molecules instead of being absorbed by them. That’s why if you’ve ever dived down deep in the sea, you’ll notice that reds quickly disappear, but greens can still be seen clearly.
The amount of red light can change with temperature too though.
Hemoglobin absorbs light energy (also known as photons) and converts it into heat energy instead. When there's more hemoglobin present than necessary, those extra photons are absorbed by free electrons in other molecules within our cells; this leads to higher temperatures and eventually causes overheating if conditions get too extreme (like on hot summer days). On the flip side, when there isn't enough hemoglobin available for this process due to insufficient oxygen levels or injuries like cuts from sharp objects like knives--it results in a blue discoloration because not enough light is getting through due an absence or deficiency of iron-containing proteins such as myoglobin.

So next time you hear someone tell you that blood is actually blue when it doesn’t have enough oxygen, you can tell them that they’re wrong, and that the blood is always red, but that the colour we see depends on a number of factors, including how much hemoglobin there is in the blood, how much light there is, the colour of the light, and even the temperature.

This is the world's largest construction project, and also one of the most controversial. NEOM, four letters that reflect the inordinate ambition of one country: Saudi Arabia. A huge region in the north-west of the country, where futuristic cities are due to spring up. The Line, Oxagon, Trojena, Sindalah and other new locations that was unveiled recently: Leyra, Norlana, Sirana and Aquellum. But between the 3D images and reality, how far advanced is the work? That's what we're going to find out today, in this new episode of Looking 4.

Watch this video to learn about how the body makes red blood cells, which contain hemoglobin and carry oxygen throughout the body. Anemia occurs when there are too few red blood cells or not enough hemoglobin.

Neuroanatomist Dr. Jill Bolte Taylor explains the 4 key ”characters” of the brain, and how understanding each can expand your perception of yourself, and the world, forever.




At age 37, neuroanatomist Dr. Jill Bolte Taylor suffered a stroke that would take her eight years to fully recover from. This is how it changed her understanding of the brain.

In this interview, Dr. Jill draws a map of the human brain, explaining how it is comprised of four distinct modules, each serving a unique role in function and personality. This combination of cognitive and emotional components gives rise to the multidimensional characters within each of us.

Are you looking to be more rational, more creative, more forgiving, or perhaps less rigid in your thinking? Dr. Jill suggests that by becoming aware of the four modules of our brains, we can consciously choose to engage specific parts. This awareness allows us to harness the true power of our brains and shape who we want to become, ultimately fostering less anxiety, more inner peace, and a vastly more purposeful life.

----------------------------------------------------------------------------------

About Dr. Jill Bolte Taylor:

Dr. Jill Bolte Taylor is a Harvard-trained and published neuroscientist. In 1996 she experienced a severe hemorrhage (AVM) in the left hemisphere of her brain causing her to lose the ability to walk, talk, read, write, or recall any of her life. Her memoir, My Stroke of Insight, documenting her experience with stroke and eight-year recovery, spent 63 weeks on the New York Times nonfiction bestseller list and is still routinely the #1 book in the category Stroke in the Amazon marketplace.

Dr. Jill is a dynamic teacher and public speaker who loves educating all age groups, academic levels, as well as corporations and not-for-profit organizations about the beauty of our human brain. She focuses on how we can activate the power of our neuroplasticity to not only recover from neurological trauma, but how we can purposely choose to live a more flexible, resilient, and satisfying life.

In 2008 Dr. Jill gave the first TED talk that ever went viral on the Internet, which now has well over 27.5 million views. Also in 2008, Dr. Jill was chosen as one of Time magazine’s “100 Most Influential People in the World” and was the premiere guest on Oprah Winfrey’s “Soul Series” webcast. Her new book, Whole Brain Living – the Anatomy of Choice and the Four Characters That Drive Our Life is a #1 release on Amazon in categories ranging from Neuroscience to Nervous System Diseases and Stroke.

There are countless articles and videos breaking down the abysmal labor practices, horrifying environmental toll, and overall mountain of waste produced by the fast fashion industry. Activists and even just large swaths of the general public have been raising the alarm about this for well over a decade, but it hasn’t stopped the rise of some of the worst offenders in the industry. For example, the ultra-fast fashion brand Shein has skyrocketed in value over the past five years largely due to their marketing success on TikTok. A lot of us know that fast fashion is bad, but the only way companies like Shein still thrive is if we convince ourselves otherwise and hit “add to cart” anyway. So why do we do it?

The answer is that e-commerce has completely warped our view of what items should cost and how long they should last (this includes and extends to our obsession with Amazon and two-day shipping). We’re moving through trends at an unprecedented pace and it’s doomed to get worse if we don’t adjust our buying habits and learn to slow down. Consumers are being manipulated, but we can do better.
