While the list below is not exhaustive, these three activities have enhanced brain functioning in controlled studies.
Take a Daily DHA Supplement– DHA or Docosahexaenoic acid is an Omega-3 fatty acid that is a central building block of brain tissue. DHA is thought to combat the inflammatory effects of cortisol and the plaque buildup associated with vulnerability to Alzheimer’s disease. According to Dr. Mehmet Oz, in one study, a dose of 600mg of DHA taken daily for 6 months led the brain to perform as if it were three years younger.
Exercise Most Days – In studies with mice, exercise led to more improved performance on cognitive tasks than exposure to enriched environments with lots of activities and stimulation. Exercise leads to increases in BDNF or brain-derived neurotropic factor, a substance that strengthens brain cells and neuronal connections. BDNF is also thought to promote neurogenesis or the creation of new brain cells from existing stem cells in the hippocampus. Although these effects can’t be studied in living human brains, researchers have found increases in BDNF in the bloodstream of humans following workouts.
Do Yoga, Meditate, or Pray – These activities can activate what scientist Herb Benson at Massachusetts General Hospital calls “the relaxation response,” which lowers blood pressure and heart rate and lowers subjective anxiety. Benson and scientists from a genetics institute showed, in a recent study, that inducing the relaxation response can beneficially alter the expression of genes involved with inflammation, programmed cell death and how the body handles free radicals. The effects shown were in the same genes implicated in PTSD and depression. According to Jeffery Dusek, Ph.D., co-lead author of the study, “Changes in the activation of these same genes have previously been seen in conditions such as post-traumatic stress disorder; but the relaxation-response-associated changes were the opposite of stress-associated changes and were much more pronounced in the long-term practitioners.”
