Are we using just 10% of our brain?
As many as 65% of Americans believe that we are using a mere 10% of our brain. Where did this myth generate from? There are various sources that could have resulted in this myth. In the 1907 edition of the journal Science, psychologist and author William James had written an article that stated that we utilize only a portion of our mental resources. However, he did not mention any kind of percentage. Best-selling author Dale Carnegie's 1936 book, ‘How to Win Friends and Influence People’ had the author stating this as something that his college professor used to say.
MRI scans of the brain during various activities show that even when you do simple activities, most of your brain is quite active, thus effectively debunking the 10% usage myth. When it comes to the weight of a brain, it weighs a mere 2% of a person's weight but uses 20 percent of their oxygen and calories.
How do you keep your brain active?
As you age, your brain cells will diminish unless you constantly keep it active. The more you use your brain, the better your mental functions will be. It’s good to take up brain-training exercises to ensure that your brain health is good. Research has showed that dementia risk was reduced by 29% amongst those who were regular with brain exercises.
Feed your brain
Like other organs, your brain needs good nutrition too. Fruits and veggies which in Vitamin E and beta carotene help improving brain health. Broccoli, blueberries and spinach are rich in Vitamin E. Carrots, sweet potatoes and red peppers are rich in beta carotene. Oily fish are rich in Omega-3 fatty acids that promote cognitive function. Salmon, tuna and mackerel are filled with this. Antioxidants are very beneficial for the brain, add walnuts, strawberries, artichokes, pecans and dark chocolate.
