Experiencing “brain fade”? Turns out that moderately intense exercise does more than helping to maintain blood pressure, improve energy, elevate mood and lower stress, it also stimulates the brain regions involved in memory. The brain releases BDNF (brain-derived neurotrophic factor), helping to rewire memory circuits. The more you move, the more brain cells you use which turns on genes to make more BDNF. Sorry, you can’t take a pill to get it – only the brain can make it, and only with regular exercise. For brain benefit raise your heart rate to 70% of maximum (roughly 220 minus your age), for about 30 minutes, 5 days/week.
