POWER UP SYOUR BRAIN


ix Ways to Boost Blood Flow by Ronica O’Hara


meat for soy and fi sh protein, eating antioxidant-rich produce such as pomegranate, blueberries, spinach and kale, and consuming lots of nitrate-rich food like celery and leafy greens which are con- verted to NO in the body. He especially recommends beets—one study reported that in juice form, it increases nitric oxide levels by 21 percent in 45 minutes—as well as dark chocolate. In a Harvard study, older people that drank two cups of hot chocolate a day for 30 days had improved blood fl ow to the brain and better memory.

ur brain has many well-known structures like the amygdala that detects danger and the prefrontal cortex that enables planning, but we oſt en take for granted the 400 miles of


blood vessels that push through a liter of blood per minute, carry- ing in oxygen and nutrients, and porting out wastes. “Our brains are highly metabolic organs, so they require lots of nutrients and oxygen to function properly, and those can only get to our brain when we have good blood fl ow,” says naturopathic physician Emilie Wilson, of the Synergy Wellness Center, in Prescott, Arizona. When that blood fl ow is optimal, we feel energized and


clear-headed; when it’s low, we feel foggy and listless. Low levels of cranial blood fl ow have been linked in brain imaging studies to strokes and dementia, as well as bipolar disorder, depression and suicidal tendencies. T e fi rst imperative for healthy cranial blood fl ow is to make sure our blood pressure, blood sugar and choles- terol numbers are in a healthy range. Health practitioners can help us address that, as well as the conditions linked to reduced blood fl ow—heart disease, hypothyroidism, diabetes, anemia, depression and smoking. To boost brain blood fl ow, specifi c lifestyle strategies have proven to be highly eff ective:

Eat strategically, especially beets and chocolate. Nitric oxide (NO) is made in the endothelium, the thin layer


of cells that line blood vessels; it relaxes the inner muscles of those vessels, maximizing blood fl ow. “T e continuous formation of NO in the brain is essential to life,” says prominent pharmacologist Louis Ignarro, Ph.D., who received the Nobel Prize in Science in 1998 for discovering that humans produce NO and that it lowers blood pressure and improves blood fl ow. He advocates passing up


Take amino acid supplements. “Consuming supple- ments containing both L-arginine and L-citrulline are well-


documented to boost the production of endothelium-derived NO,” says Ignarro. “Adding antioxidants to the amino acid mix provides added benefi t by increasing NO levels.” He recommends pomegranate extract, cocoa fl avonols and omega-3 supplements.


Move the body. Fast walking, running, cycling, swimming, ball playing, weight liſt ing and yoga all help improve cranial


blood fl ow, says Ignarro: “Physical activity stimulates the produc- tion of NO in all arteries, including those in the brain.” In one study, women over 60 that walked for 30 to 50 minutes three or four times a week increased ongoing cranial blood fl ow up to 15 percent. Yoga exercises like downward dog and shoulder stands also raise blood fl ow in the head.

Play music. Research using functional magnetic resonance imaging published in Scientifi c Reports found that blood


fl ow in the brain increases when people listen to music they love, whether it’s Mozart or Eminem. In a recent study, Weightless, a song written by the British group Macaroni Union along with sound therapists, reduced participants’ anxiety levels by 65 per- cent and physiological resting rates by 35 percent.


Do a chanting meditation. Kirtan Kriya, a 12-minute daily meditation that includes chanting, fi nger movements


and visualization, “has been researched for over 18 years and has documented benefi ts in increasing blood fl ow to the brain,” says Krystal Culler, senior Atlantic fellow with the Global Brain Health Institute, in San Francisco and Ireland. YouTube off ers several ver- sions, as does the Alzheimer’s Research and Prevention Foundation (Tinyurl.com/12MinuteYogaMeditation).

Consider acupuncture and craniosacral therapy. “Acupuncture has been used for thousands of years to boost


blood fl ow, and it can also relax tense muscles in the neck and head, which can impair blood fl ow more than we realize,” says Wilson. She also recommends the gentle, hands-on-head ap- proach of craniosacral therapy: “It can directly improve blood fl ow by removing restrictions, and it can also rebalance sympa- thetic and parasympathetic functions, which has benefi cial eff ects on our nervous system and on blood fl ow.”
