What Do I Need To Know About My Brain?
The human brain in an incredible thing! It’s one of the most complex and least understood parts of the human body, but science is making new advances every day that tell us more about the brain.
The average human brain is 5.5 inches wide and 3.6 inches high. When we’re born, our brains weigh about 2 pounds, while the adult brain weighs about 3 pounds.
The brain accounts for about 2% of your total body weight, but it uses 20% of your body’s energy!
It sends out more electrical impulses in one day than all the telephones in the world, and it’s estimated that the brain thinks about 70,000 thoughts in a 24-hour period.
The brain needs oxygen to survive. Unconsciousness generally occurs about ten seconds after the brain loses blood flow.
It can live for anywhere between 4 to 6 minutes without oxygen, but after that, its cells begin to die, which is one cause of brain injury.
