… and everything neurological.
Fascinating organ, your brain.
One would be forgiven if they didn’t know it consists of up to 60% fat … or that there are — and this is truly mind-boggling — 100,000 miles of blood vessels in your brain.
You already know it controls every other function in the body, to include voluntary and involuntary movements, such as breathing, digestion, temperature regulation, blood flow and other involuntary process.
But what you may not know is how expensive it is on your body to manage it all.
For example, did you know your brain uses 20 percent of the total oxygen in your body?
- Or that your brain generates between 10 and 23 watts of power — or enough energy to power a light bulb?
- Or that the weight of your brain is about 3 pounds … but due to the 33 muscles in your head and face, the 22 separate bones in your skull, and water and blood volume … the average person’s head weighs 8% of their total bodyweight?
- Or that the tough, leathery brain covering just under the skull is called the dura mater, literally meaning “tough mother?”
It’s all true.
Not only that …
… Your brain is made up of about 75 percent water, and we know electrical currents pass easily thorough H2o, so stay well hydrated, because studies are proving that dehydration not only effects the size of the brain, but how hard it works.
… Scientists in the UK have discovered that 90 minutes of sweating without replenishing lost fluids shrinks the brain as much as a year of aging. (Let that sink in for a moment)
… Dehydration also causes brain withering equivalent to two and half months of Alzheimer’s disease. (Read that last sentence again!)
… At just 1.1% body water weight loss (about 1.1% dehydration), researchers observed increased neural effort when performing common cognitive tasks, effecting short term memory, long term memory recall, arithmetic and general problem solving.
… Dehydrated women experience a significant drop-off in energy and mood … feeling tired and lousy about life … were more likely to have headaches … and report difficulty concentrating (And it’s so preventable!)
It all happens because your brain is hyper-sensitive to even small changes in the amounts sodium and potassium found in your body’s fluids.
But it’s not all about hydration.
Food matters too!
For example: A study of 1 million students in New York showed that students who ate lunches that did NOT include artificial flavors, preservatives, and dyes did 14 percent better on IQ tests than students who ate lunches with these additives.
The take-away from all this is simple.
Stay hydrated and eat a clean, balance diet.
To you health,
P.S. You may also find these other ‘brain twisters’ (pun intended) fascinating as well.
Amazingly, there are no pain receptors in your brain, so your brain can feel no pain.
Humans continue to make new neurons throughout life in response to mental activity.
You can’t tickle yourself because your brain distinguishes between unexpected external touch and your own touch.
Every time you recall a memory or have a new thought, you are creating a new connection in your brain.
Memories triggered by scent have a stronger emotional connection, and therefore appear more intense than other memory triggers.
Most people dream about 1-2 hours a night and have an average of 4-7 dreams each night.
Studies show that brain waves are more active while dreaming than when you are awake.
Some people (about 12 percent) dream only in black and white while others dream in color.
