What is Brain Health?

Brain health is something that we all need to be aware of.  Approximately 1 in 3 Canadians is impacted by a brain health disorder, which means we need to be proactive in taking care of ourselves.  Brain health starts with maintaining a healthy lifestyle; good nutrition, physical activity, and healthy communications with those around us will impact the quality of our lives.   

Brain Facts

  1. Your brain weighs approximately 2% of your body’s weight but uses 20% of your total energy and oxygen intake. 
  2. Your brain is 73% water. Just 2% dehydration can show declines in attention, memory and other cognitive skills. 
  3. Your brain weighs about 3 pounds. Of that, the dry weight is 60% fat, making your brain the fattiest organ. Eat healthy fats such as salmon containing omega-3 to help support brain structure.
  4. Recent evidence has suggested the brain contains at least 86 billion brain cells. 
  5. Even 5 minutes without oxygen can create brain damage. 
  6. Babies have big heads to hold rapidly growing brains. A 2-year-old’s brain is 80% of adult size. 
  7. Teen brains are not fully formed until about the age of 25. The prefrontal cortex responsible for reasoning and impulse control is still developing in this time. 
  8. The average brain has around 50,000 thoughts per day and 70% of them are believed to be negative. Work on perceiving situations in a more positive light!
  9.  In general, men’s brains are 10% bigger than women’s, even after taking into account larger body size. 
  10. The sperm whale’s brain is the largest known to man, weighing 17 pounds! Humans however have the largest brain in relation to body size. 
  11. There is no such thing as a left-brain or right-brain personality type. We are not left-brained or right-brained; we are “whole brained.” 
  12. The human brain is not solid. It’s soft and squishy similar to the consistency of soft tofu or soft gelatin. The brain is very fragile! Remember to protect your head by wearing a helmet when necessary. 
  13. A blood-brain barrier protects your brain from foreign substances. But it doesn’t work perfectly. The nicotine in smoke rushes into the brain in a mere 7 seconds. Alcohol on the other hand takes 6 minutes. 
  14. You have no pain receptors in your brain! This explains how brain surgery can be performed while the patient is awake with no pain or discomfort.
