How to Improve Circulation of Oxygen to Brain

1). Breathe deeply. Go ahead, take a deep breath. A lot of people get into the habit of breathing shallowly. This can result from being sedentary or even from trauma. Also, because of deforestation, there might be less oxygen in the air than ever in history, so we may have to breathe more deeply to get it.
2). Exercise. Move it. Exercising increases blood flow in general. It is critical to getting enough oxygen. Among other benefits, it will build alveoli in the lungs, so more oxygen can be absorbed.
3). Get your iron. Iron has a role in oxidative metabolism---it carries oxygen in the blood. Excess iron is excreted, but having enough iron is critical to getting oxygen to the brain.
4). Consider taking supplements. Some believe taking vitamin B6 will help increase oxygen to the brain because it is involved in hemoglobin synthesis. Studies at Hebei Medical University and the Indiana University Medical Center have found that Ginkgo biloba increases blood flow and thus oxygen levels to the brain.
