There is an often repeated saying in healthcare, “what is good for the heart is good for the brain.” And I might add vise-versa, what is good for the brain is also good for the heart. So what is the heart brain connection, blood supply and oxygen.

The brain has 100 billion cells, which is also the number of stars in the galaxy. All of those cells need to be constantly fed, requiring a constant blood supply to keep up the metabolic demands. At all times over 20% of the blood in the body is located in the brain. That blood supply always needs to be highly oxygenated. Loss of oxygen for even 8-10 minutes can result in brain damage.

What is good for the heart and brain:

  • a oxygen rich environment
  • highly nutritious diet and hydration
  • low stress life style

We know that when a person has been diagnosed with dementia, they have already lost brain cells. Brain cells will die due to disease and poor life style choices. Smoking will not only suffocate the lungs but reduce that brain sustaining oxygen supply. Bad dietary choices create inflammation and are now proven to be as harmful as smoking.

This complex organ, the brain, is only 3-4 pounds depending on the size of the individual, about the size of a cantaloupe. When a baby is born they already have their 100 billion cells, what they don’t have is the connections between the cells. And those trillions of cell connections we call learning. To support that development, and even to survive, the brain needs the nutrients and oxygen from the heart.

The blood supply to the brain is so important that when the body experiences a reduction in oxygen it will automatically redirect blood to the brain. Increasing the blood supply even two times the normal volume.

Improving the supply of oxygen and nutrition to the heart and brain, can be accomplished day by day, meal by meal, through life style changes. Start by opening a window.
