    The brain is among the most complex organs in the body. It’s the nervous system’s command center that controls all of our functions, such as eating, walking, talking, and more. Numerous studies have been made to understand how it works, yet so much of it is still a mystery.

    Find out how powerful it is with these interesting facts.

    We Use More Than 10% Of Our Brains

    Each part of your brain does a different job; you use almost all of them throughout the day.

    For a long time, there has been a misconception that we only employ 10% of our brains. The truth is we actually use all of it, even when we’re sleeping. The brain is constantly active because it is continuously responding to stimulation. However, its activity patterns and the degree of activity vary based on what we’re doing and whether we’re awake or asleep.

    Good Cholesterol Is Essential For Memory

    Cholesterol in the brain helps neurotransmitters like dopamine and serotonin communicate.

    In July 2008, a study in the journal Arteriosclerosis, Thrombosis, and Vascular Biology: Journal of the American Heart Association found that people with low levels of high-density lipoprotein (HDL, sometimes called “good cholesterol”) were more likely to have memory loss than those with higher levels. This shows that having a lot of HDL is linked to better memory.

    The good news is you can regulate your cholesterol levels with a healthy diet. Whole, unprocessed food such as vegetables, fruits, beans, whole grains, and fish are excellent sources of good cholesterol.

    The Brain Uses 20% Of The Body’s Oxygen

    Getting more oxygen to the brain can be done by walking quickly for 30 minutes three or four times a week.

    Despite making up only 2% of the body weight, the brain demands enormous amounts of oxygen due to the energy required.

    When the brain and its surrounding tissues don’t get enough oxygen, the brain is at risk of brain hypoxia. Hypoxia in the brain happens when it does not receive enough oxygen despite the presence of blood flow. Some causes of brain hypoxia include suffocation, drowning, stroke, and cardiac arrest. It is critical to treat brain hypoxia immediately to restore normal brain function as soon as possible to prevent complications.
