Your brain is one of the most powerful and mysterious organs in your body. It controls everything from your thoughts to your emotions and even processes information at lightning speed. But how much do you really know about it? Some long-believed myths about the brain have been debunked, while other surprising facts reveal just how incredible this organ truly is. Get ready to be amazed by these fascinating brain facts!

You’ve probably heard this one before, but it’s completely false! While it’s true that not all parts of the brain fire at the same time, imaging studies show that most regions are active throughout the day, even when we sleep.

Your brain is constantly working, controlling bodily functions and emotions, and processing information. So next time someone says you’re only using 10% of your brain, you can confidently tell them that’s just a myth!

Here’s a weird fact: While your brain processes pain signals from the rest of your body, it has no pain receptors of its own. This is why surgeons can perform brain surgery on conscious patients without causing them pain.

However, the membranes and tissues surrounding the brain do have pain receptors, which is why headaches and brain injuries can be so excruciating.

How come we have headaches if the brain has no pain receptors? Well, that’s because headaches are triggered by chemical activity in the brain, changes in nerves and blood vessels, and even fluctuating serotonin levels.

In some cases, hormones like estrogen can also play a role, which explains why migraines are more common in women.

Dreams are proof that your brain never rests! (Warning: this fact can make you feel exhausted.) While you sleep, your limbic system, that is, the part of the brain that deals with emotions, becomes especially active, which is why dreams often feel so intense.

On average, humans experience four to seven dreams per night, even if we don’t always remember them. And what about that scary nightmare about falling? Well, you can thank your amygdala, the brain’s fear center, for that one.

Have you ever walked into a room and instantly forgotten what you were after? That’s because short-term memory only lasts about 20-30 seconds! That’s not enough!

Your brain holds a limited amount of information in its active state before deciding whether to store it or discard it. Ironically, we can’t really choose what makes the cut, but we do hope these facts stay with you!

That sharp, icy pain when you eat something too cold? It’s your brain’s way of telling you to slow down! Officially called sphenopalatine ganglioneuralgia, a brain freeze happens when cold food or drinks rapidly chill the blood vessels in your throat, causing them to constrict and then rapidly expand. This sends pain signals to your brain, warning you of the sudden temperature shift. It’s annoying, but it’s actually your body trying to protect itself!

You didn’t need us to tell you, but let’s look at the details: The average person has between 12,000 and 60,000 thoughts per day. What’s even more interesting? 95% of those thoughts are the same ones you had yesterday. Is that not surprising enough? Hear this out: 80% of them tend to be negative. That’s because our brains are wired for survival, constantly analyzing risks and potential dangers.

Even though it only makes up about 2% of your body weight, your brain employs a major quantity of energy! It consumes 20% of your oxygen and blood supply, making it one of the most demanding organs in your body.

If your brain goes without oxygen for just five minutes, brain cells start dying, leading to irreversible damage. This is why deep breathing and cardiovascular exercise are great for brain health!

Do you know that feeling when you hit the back of your head and see stars? That’s because your occipital lobe, which controls vision, is located at the back of your brain. If you get hit there, your brain momentarily misfires, causing flashes of light.

Interestingly, your brain processes vision on the opposite side; while your right brain controls your left eye, your left brain controls your right eye. It’s one of the many ways the brain operates in a complex way.

Believe it or not, your brain generates between 12 and 25 watts of electricity when you’re awake. If you can’t really grasp how powerful that is, check this out: It’s enough to power a small light bulb! Your brain’s electrical activity is what allows neurons to send signals at speeds of up to 260 miles per hour.

Your brain may be the fattiest organ in your body, consisting of at least 60% fat! This is why consuming healthy fats, like omega-3s and omega-6s present in fish, for example, is essential for brain health.

Healthy fats stabilize brain cell walls, reduce inflammation, and support cognitive function. So go ahead and enjoy that avocado toast, it’s food for your brain!

It’s not just your memory that fades over time; the brain itself physically shrinks as one gets older. It continues developing until your late 40s, but after that, it slowly decreases in size.

Now, size doesn’t equal intelligence, so a smaller brain doesn’t necessarily mean a less capable one. Staying mentally active, exercising, and eating brain-boosting foods can help keep it in top shape!

We often think of cholesterol as bad, but your brain actually depends on it! In fact, 25% of your body’s cholesterol is stored in your brain, where it helps with learning and memory. However, unlike other organs, the brain can’t absorb cholesterol from the blood, it has to produce its own. So, while too much cholesterol in the body can be harmful, the right amount is vital for brain function. At least you can use that as an excuse to get that burger!

Deep roots

11 everyday words with indigenous roots

English is a very welcoming language in the sense that it incorporates terms from many other languages from all over the world. And, as it couldn’t be otherwise, Native American languages have lent many of their words and terms to English speakers. Some traveled through Spanish or French before settling into English, and others arrived directly through early contact and trade, helping shape the way we speak today. Did you know about these 11 terms?

The word "canoe" comes from the Taino term canoa, which was first used by Caribbean islanders long before Europeans arrived. Early explorers adopted it to describe the slim, sturdy boats they saw.

Over time, "canoe" became the standard English word for a small paddled craft. Today it still carries that sense of simplicity and closeness to nature.

The word "barbecue" comes from barbacoa, another Taino term for a wooden frame used for cooking meat over fire. Europeans adopted it and applied it to both the method and the gathering itself.

Today, "barbecue" means everything from a backyard cookout to a regional cooking style. Its origins highlight the deep culinary influence of Native Americans in the nation's current culture.

"Skunk" comes from the Algonquian word squnk, which means "urinating fox" (quite a fitting term, indeed). This was an obvious reference to the animal’s strong defensive spray. Early settlers adopted the term directly.

Since English had no better name for the creature, the Native word stuck. Today, the word skunks is also used as playful slang.

The word "moose" originates from Eastern Abenaki, a part of the Algonquian family, where it meant "he strips off bark." Yes, it described the animal’s habit of tearing bark from trees.

The name entered English quickly because settlers relied on Native knowledge of local fauna. The word remains unchanged because of its accuracy and usefulness.

"Raccoon" comes from the Powhatan word arakun, meaning "he scratches with his hands." It described the animal’s clever, humanlike front paws.

Settlers adopted the term because it captured the creature’s behavior beautifully. Today, the raccoon is used as a household symbol of curiosity, not unlike the animal itself.

The term "chipmunk" most probably comes from the Ojibwe word ajidamoo, which means "one who descends trees headfirst." Early English settlers adapted the sound into today’s form.

Though the spelling changed over time, the lively image of a chipmunk racing down a tree face-first stayed.

The word "caribou" comes from the Mi’kmaq term qalipu, which means "snow shoveler," referring to the animal’s habit of digging through snow for food.

French settlers brought the word into English, keeping its descriptive nature. The name still connects the modern animal to the winter landscapes it belongs to.

"Totem" comes from the Ojibwe word ototeman, which means "kinship group." It described symbols representing clans and shared roots.

English adopted it to describe carved poles and symbolic elements. Though broader in modern usage, it still hints at the original sense of community, identity, and heritage.

"Coyote" comes from the Nahuatl word coyōtl, which was used by Indigenous tribes of central Mexico. Spanish speakers adopted it, and English borrowed later.

The word kept its meaning, and it remains one of the most direct links between the English language and Nahuatl.

The tasty avocado’s name traces to the Nahuatl word ahacatl, which refers to the fruit and to a body part as well. Spanish speakers transformed it into aguacate.

Later on, English speakers adapted it to avocado. While the name sounds contemporary and culinary, it has ancient Native roots.

The last Nahuatl word and also the last word on the list comes from the term xocolātl, which describes a bitter cacao drink that was consumed long before Europeans arrived in America. The name traveled from Spanish to English.

Though the product changed dramatically, the word survived. Today, chocolate is a universal symbol of sweetness, with rich and deeply indigenous roots.
