Get moving.

A wealth of recentresearch, including a new study published this month in the Journal of Alzheimer's Disease, suggests that any type of exercise that raises your heart rate and gets you moving and sweating for a sustained period of time — known as aerobic exercise — has a significant, overwhelmingly beneficial impact on the brain. Those benefits may start to emerge as soon as you start working out regularly.

"Aerobic exercise is the key for your head, just as it is for your heart," write the authors of an article in the Harvard Medical School blog "Mind and Mood."

The less frequently the participants exercised, the weaker the connections in their brain's white matter and the more poorly they performed on a bunch of cognitive tests.

"This research supports the hypothesis that improving people’s fitness may improve their brain health and slow down the aging process,” Kan Ding, a neurologist with the Peter O’Donnell Jr. Brain Institute and the lead author on the paper, said in a statement.

Here's what science says about coffee and cancer risks

  Here's what science says about coffee and cancer risks Trouble is brewing for coffee lovers in California, where a judge ruled that sellers must post scary warnings about cancer risks. But how frightened should we be of a daily cup of joe? Not very, some scientists and available evidence seem to suggest. Scientific concerns about coffee have eased in recent years, and many studies even suggest it can help health. "At the minimum, coffee is neutral. If anything, there is fairly good evidence of the benefit of coffee on cancer," said Dr. Edward Giovannucci, a nutrition expert at the Harvard School of Public Health.

Exercise may help keep the brain young

As we age, the brain — like any other organ — begins to work less efficiently, so normal signs of decline begin to surface. Our memory might not be quite as sharp as it once was, for example.

Exercising regularly as we get older appears to help defend against some of this decline, both for healthy people who show normal signs of aging and for older people who may be on the path toward developing Alzheimer's disease.

Researchers still aren't sure why this is, or how it happens. Exercise could strengthen some of the pathways our brain uses to relay signals for recent events, or boost the size of certain brain regions that are key for learning and storing memories.

Regardless of the specific mechanism at play in our bodies, the most recent recommendations suggest that working out twice a week may be beneficial in curbing some symptoms of mild cognitive impairment (MCI), a stage that precedes the development of Alzheimer's in some older people. This typically involves more serious problems with memory, language, thinking, and judgment than those that might be displayed by a healthy older person.

Most studies focusing on people with MCI require people to either work out or self-report their own fitness levels. But the latest study measured how fit people were by studying their breathing and heart rate. The researchers then used brain imaging to measure the functionality of peoples' white matter and had them take a series of cognitive tests designed to measure how sharp they were.

Overall, they found that the less fit people were, the weaker their brain's white matter connections, and the worse they did on the cognitive tests.

Two other recent studies of older people with MCI have suggested that merely amping up one's workout routine with the right moves could help slow the brain's decay.

Last May, scientists recruited adults with MCI between the ages of 60-88 and had them walk for 30 minutes four days a week for 12 weeks. The results showed strengthened connectivity in a region of the brain where weakened connections have been linked with memory loss. That development, the researchers noted, "may possibly increase cognitive reserve," but more studies are needed.

There ' s even more evidence that one type of exercise is the closest thing to a miracle drug that we have . " We have more work to do to determine why that is." How aerobic workouts clear our minds and lift our mood.

Another study, this time of exclusively older women with MCI, found that aerobic exercise was tied to an increase in the size of the hippocampus, a brain area involved in learning and memory.

Large groups of researchers are taking note of these promising findings. In December, the American Academy of Neurology updated its guidelines to reflect the takeaways of these findings. Based on a series of 6-month studies on aerobic workouts and memory in people with MCI, the new guidelines recommend that people diagnosed with the condition do some form of cardio exercise at least twice a week.

Working out could boost your mood, too

In addition to protecting the brain from aging, cardio workouts "have a unique capacity to exhilarate and relax, to provide stimulation and calm, to counter depression and dissipate stress," according to the article in Harvard's "Mind and Mood" blog.

The reason aerobic workouts lift our spirits seems related to their ability to reduce levels of natural stress hormones, such as adrenaline and cortisol, according to a study in the Journal of Physical Therapy Science. Activities like running and swimming also increase overall blood flow and provide our minds fresh energy and oxygen — another factor that could help us feel better.

Can You Be Allergic To Exercise?

  Can You Be Allergic To Exercise? Being "allergic to exercise" sounds like a lie you'd tell your gym teacher to get out of class, or a phrase you'd see printedOn fitness Reddit threads, people say that whenever they do cardio, their thighs and legs get "insanely itchy" to the point where they have to stop working out. Others say their waist itches uncontrollably while running. And, some say they itch on the elliptical, regardless of what they're wearing.

A pilot study in people with severe depression found that just 30 minutes of treadmill walking for 10 consecutive days was "sufficient to produce a clinically relevant and statistically significant reduction in depression."

So whether you're looking for benefits related to mood or memory, the take-home message is clear: the more you move, the healthier you may be.

"It's exciting that exercise may help improve memory at this stage, as it's something most people can do and of course it has overall health benefits," Ronald C. Petersen a fellow of the American Academy of Neurology and the lead author on the most recent guidelines, said in a statement.
