The human brain is an incredible organ, constantly working behind the scenes to keep us thinking, moving, and experiencing the world. Here are some mind-blowing facts about your brain:
The average brain weighs about 3 pounds and contains approximately 100 billion neurons.
There are about 100,000 miles of blood vessels in the brain—enough to circle the Earth four times!
Neurogenesis (new neuron formation) happens throughout life—as long as you keep your brain active with mental challenges.
The brain uses 20% of the body’s total oxygen, even when at rest.
Chronic stress can physically alter brain cells, impacting their structure and function.
You can’t tickle yourself because your brain can predict and cancel out the sensation of self-touch.
Your brain generates 10-23 watts of power when awake—enough to light up a small bulb.
Each time you blink (~20,000 times a day), your brain prevents your vision from “going dark.”
You experience around 70,000 thoughts per day.
The brain is 75% water—hydration is key to brain function!
Fit Body, Fit Brain
Or, as the Romans put it:
“Mens sana in corpore sano” – A sound mind in a sound body.
Modern research confirms what ancient wisdom suggested—what’s good for your body is also great for your brain.
Exercise is a brain booster! Regular aerobic and resistance training can help prevent and manage:
✔ Hypertension, heart disease, stroke, and type 2 diabetes
✔ Osteoporosis, arthritis, and high cholesterol
✔ Stress, depression, and cognitive decline
Plus, exercise enhances brain cognition, which includes:
✔ Thinking
✔ Reasoning
✔ Memory
✔ Creativity
✔ Learning
Bottom line: A well-rounded brain workout includes physical exercise + mental challenges like language learning, puzzles, and strategy games.
So whether it’s aerobics, strength training, or a Sudoku puzzle, keeping your body and mind active is one of the best things you can do for long-term health.
