A question that has managed to inspire the scripts of some of the most popular films - but what is the truth and what does science say about it?
According to a 2013 poll, about 65% of Americans believed that we only use 10% of our brains.
But this is just a myth!
The best neurologists are in consensus on this and the correct answer to the question is… Everyone!
In fact, according to neurologist Barry Gordon, 'Most of the brain is almost always active, except in a few special cases'.
The human brain is complex and mysterious. This is certainly the reason why questions and misunderstandings about its function persist to this day.
Finally, since antiquity, philosophers and intellectuals have taken the 'brain' as a subject in their studies.
As we said, the correct answer is: Everyone!
The only time certain brain regions are not used is when brain injury or disease has destroyed those areas.
Which part of the brain we use at any given moment varies depending on what we are doing or thinking, but it is not at all true that people only use a small part of the brain's capacity or 10% of it!
Use of brain energy
The brain uses approximately 20% of the body's energy, even though it makes up much less than 20% of the body's total mass. So there are several methods how you can improve its function.
1 – Eat nutritious foods
Research suggests that certain micronutrients may play an important role in brain health. Eating a diet rich in antioxidants, such as vitamin E and beta carotene, can help protect against many chronic diseases and also promote a healthy brain. You'll find antioxidants in brightly colored fruits and vegetables, such as blueberries, spinach and sweet potatoes. Etc.
Omega-3 fatty acids, which are most commonly found in fish, are also essential for brain health. Try to consume at least two servings per week, or talk to your doctor about whether fish oil supplements are right for you.
2 – Exercise your brain
You've seen the apps that promise to stop your brain from aging. There is some truth to their claims; cognitive training helps reduce the risk of dementia.
But any form of mental exercise can be effective.
Try crosswords and other word games, jigsaw puzzles, reading or learning a new skill.
Adding social stimulation (such as learning a new language in a group setting) also supports your brain health.
3 – Exercise your body
Physical exercises are important for physical health, but also for mental health. Physical activity actually changes the structure and function of the brain, which helps it function well.
Exercise increases blood flow to the brain and helps deliver energy, in the form of glucose, to brain cells.
4 – Get enough sleep
Just as nutrition and exercise support physical health and the brain, good quality sleep has the same effect.
Sleep can improve memory and reduce mental fatigue.
According to studies, "Each phase of the sleep cycle restores and renews the brain for optimal function."
How do you achieve this?
Hydrate yourself
Drinking enough water not only protects you from symptoms like headaches and dizziness, but your brain also needs enough water to function at its best.
So make sure you drink plenty of water and other non-alcoholic, non-caffeinated beverages to fuel your body and brain – but not more than necessary, as this risks "washing" you out of the vitamins, nutrients and electrolytes present in your body. which are difficult to replace.
