When we think of “boosting
brainpower,” tasks like crossword puzzles, reading and even learning a
new language might first come to mind.
While these things can certainly help to improve intelligence and mental clarity, what likely has an even larger affect is the ordinary choices we make on a daily basis .
From the foods we eat to the amount we sleep each night , our daily habits shape the way our brains continue to grow and function.
Whether
you’re looking for a way to improve your focus, enhance your intellect
or simply just want to ensure your brain stays sharp and healthy now and
later on in life , the following healthy habits are proven ways to protect and enrich your mind.
Not Smoking
According to
Eric Topol, M.D. , the Men’s Health cardiology advisor, among other factors like poor blood pressure, obesity and
a sedentary lifestyle ,
smoking accelerates the natural degeneration of the brain that comes
along with age. These factors, he noted, “promote heart disease, and are
critical to our blood supply and plenty of brain-heart interactions.”
Plus, in addition to the
large toll it takes on so many aspects of overall health , some research has shown that smoking may cause thinning in the cortex of the brain, where, according to
WebMD , important processes like memory, language and perception take place.
Enjoying Alcohol in Moderation
If you like to
enjoy a cocktail every now and then , the good news is that
some research
has shown that a daily drink may actually help to prevent against
cognitive decline. The bad news is, by going overboard with alcohol,
you’re likely putting the health of your brain (and other parts of your
body and overall health) in danger. According to the
National Institutes of Health ,
long-term heavy drinking can actually shrink the frontal lobes of your
brain, which leads to impaired thinking skills. Additionally, a study
published in Alcoholism: Clinical & Experimental Research (the
official journal of the Research Society on Alcoholism and the
International Society for Biomedical Research on Alcoholism), found a
reduction in white matter pathways in the brains of recovering
alcoholics, when compared with non-alcoholics. According to study
co-author
Catherine Brawn Fortier ,
a neuropsychologist and researcher at the VA Boston Healthcare System
and assistant professor at Harvard Medical School, white matter connects
the frontal lobes to the rest of the brain. "The frontal cortex is the
integration center for all other parts of the brain that are important
to behavior and cognitive function,” she said. “These pathways support
self-monitoring, planning, judgment, and reasoning." In other words, if
you want to keep your mind sharp and healthy, keep your cocktail count
to about one drink a day or less.
Lifting Weights
If you really want to improve the
power of your mind, research shows that in addition to aerobic exercise
and yoga, you should also include some
strength training in your fitness routine. According to
one study ,
two resistance training sessions a week helped to improve brain
performance in older women with mild cognitive impairment. "What our
results show is that resistance training can indeed improve both your
cognitive performance and your brain function," professor Teresa
Liu-Ambrose, who led the study at the University of British Columbia,
told
CBC News .
"What is key is that it will improve two processes that are highly
sensitive to the effects of aging and neurodegeneration: executive
function and associative memory — often impaired in early stages of
Alzheimer's disease."
Practicing Yoga
Yes,
yoga might actually make you smarter.
One study
from the University of Illinois at Urbana-Champaign found that 20
minutes of yoga enabled 30 female subjects to better complete mental
tasks that tested the speed and accuracy of their working memory and
other measures of cognitive function. Plus, the results showed that yoga
may be even more powerful when it comes to boosting brainpower when
compared to intense aerobic exercise.
Managing Stress
Jennifer Owens, an integrative
mental health and wellness expert
who has been working in the holistic health field for more than a
decade specializing in stress and anxiety management, points to
studies
that show how relaxing activities like meditation can increase gray
matter in the brain. “Increased grey matter can make the brain better at
managing emotions, controlling attention, maintaining focus and more,”
she explained. Additionally, other studies have shown that
stress may lead to brain shrinkage , so finding a method of
stress-management — like deep breathing or other relaxing activities such as
yoga ,
meditation or
walking — that works well for you is essential for maintaining a healthy brain.
Exercising Regularly
Study after study
continues to show that regular exercise is one of the best ways to
ensure your brain will stay healthy and sharp. The connection between
exercise and improved cognitive function is so strong that researchers
have recently moved on to figuring out exactly
how the two factors are associated . Regardless, by keeping up with a regular workout routine, you’re
benefiting your brainpower
by improving functions like task switching, selective attention and
working memory capacity. Plus, some research has shown that exercise
even
increases brain volume .
Eating Your Veggies
There are a wide range of nutrients and different
foods that promote healthy brain function .
In particular, though, cruciferous vegetables like broccoli,
cauliflower, kale, cabbage, bok choy and Brussels sprouts may be
especially beneficial. “These
vegetables
are rich sources of minerals, vitamins and many important
phytochemicals; especially many sulfur containing compounds,” explains
Dr. Michael S. Fenster, M.D., a board certified interventional
cardiologist and author of
The Fallacy of the Calorie: Why the Modern Western Diet is Killing Us and How to Stop It .
“As such, they help our bodies deal with oxidative stress by providing a
natural source of antioxidants.” Fenster says these effects lower the
risk for cancer and promote heart health, which ultimately reduces
conditions that negatively affect brain function. “Diets rich in these
types of vegetables have been associated with less decline in memory,
attention and verbal abilities,” he added. To go one step beyond just
veggies, it’s also worth noting that some studies have shown the
Mediterranean Diet is particularly helpful in preventing cognitive decline as well.
Making Sleep a Priority
Sleep is so important for
many different reasons .
Sleep deprivation — especially when it’s chronic — can negatively
affect nearly every aspect of your health, but it especially takes a
toll on the brain. According to an
infographic on Mic.com ,
lack of sleep can cause long-term memory loss, emotional instability,
feelings of fogginess and confusion, and even brain shrinkage— just to
name a few of the negative effects. What’s more, according to
Help Guide experts Melinda Smith, M.A., Lawrence Robinson, and Jeanne Segal, Ph.D, some studies have shown that regular,
quality sleep is necessary for flushing toxins from the brain.
Keeping Your Gut Healthy
A growing body of research shows that the condition of
the digestive system actually plays a pretty significant role in our overall health .
Specifically, researchers are finding a strong link between digestive
health and the brain. “The bacteria that reside in the gut appear to
play an important role and are able to communicate with the central
nervous system notably through neural, endocrine and immune pathways,”
says Dr. Helene M. Savignac Ph.D., an expert in neuropsychology,
cognitive and behavioral science, and the brain research manager for
Clasado Research Services Ltd .
“By influencing the balance and types of bacteria present, studies show
that it may be possible to lower stress, affect cognition/brain
processes and mood.” What can you do to enhance your digestive health?
Well, to start, certain foods like yogurt, sauerkraut, kombucha and
coconut keifer can help maintain the “good” bacteria needed to keep your
gut running smoothly.
