1. Get More Sleep
Experts agree that if you do only one thing
to improve your memory, getting more sleep should be it. “Sleep is key
time for your brain to solidify the connections between neurons,” says
Barnard. In a study published in the journal
Sleep Medicine,
researchers asked subjects to perform some memory tasks and then either
take a nap or stay awake. The people who napped remembered more of the
tasks they had performed than did those who stayed up. Rule of thumb:
Get seven to nine hours of sleep total each day. And, yes, naps count.
2. Jog Your Memory
Literally.
Running—or biking or swimming or doing any other type of cardiovascular
activity—for 20 to 30 minutes three times a week has been proven to
help you remember things better. Raising your heart rate gets blood
flowing to your brain, enlarges the hippocampus (the most vital part of
the brain for memory), and increases the secretion of brain-derived
neurotrophic factor, a protein necessary for long-term memory. Also,
“cardiovascular exercise can actually cause new connections to sprout
between neurons in the hippocampus,” says Peter J. Snyder, a professor
of neurology at Brown University’s Alpert Medical School.

3. Have Some Food (and Drink) for Thought
Your
brain can’t function properly without essential nutrients and chemical
compounds. “Blueberries are the top source of substances called
anthocyanins, which are brain-boosting antioxidants,” says Joy Bauer. “Studies have shown that anthocyanins shield the brain against
inflammation and oxidation, both of which can damage neurons and make
them less effective at communicating with one another.” Bauer also
recommends fitting in leafy green vegetables as often as possible.
“Long-term studies have shown that people who eat large amounts of
spinach, kale, and other leafy greens have less age-related memory
decline, thanks to phytonutrients like vitamin C,” she says. You might
also want to start enjoying a drink with dinner. Research published in
The New England Journal of Medicine
found that women who had one drink a day were 20 percent less likely
than teetotalers or heavier drinkers to experience a decline in their
cognitive function, including the ability to remember points of a
paragraph that had been read to them 15 minutes earlier. The researchers
believe this may be because moderate alcohol consumption elevates
levels of HDL cholesterol (the good kind) and improves the condition of
the blood that reaches the brain.
