We all want to stay sharp as we age. But unhealthy choices and unintentional missteps could be messing with your brain health. Here, Rahul Jandial shares which harmful habits are hampering your brainpower, plus tips to keep your cognitive function in fighting shape.
1. Sitting All Day.
Sitting all day is detrimental to your overall health. And your brain is no exception. “Sitting is inactivity, and inactivity is bad for the brain,” Dr. Jandial says.
That’s because movement “keeps the brain arteries open, allowing the delicate neurons to stay irrigated with nourishing blood,” he explains. In other words, physical activity boosts blood flow and, in turn, transports oxygen and essential nutrients to the brain.
Plus, it improves mood and reduces stress, which are both beneficial for brain health. So, when you sit on your bum a lot, your brain isn’t reaping the benefits.
Move more and sit less. Adults should do at least 150 minutes a week of moderate-intensity or 75 minutes a week of vigorous-intensity aerobic physical activity. If that sounds like a lot, keep this in mind: Any physical activity is better than none. Even little movement breaks throughout the day can add up.
2. Being Antisocial.
“While some people thrive on solitude, most do not,” Dr. Jandial says. And skipping opportunities to be social may be sabotaging your brain.
“Loneliness is linked to depression,” Dr. Jandial says. And it can also play a role in cognitive decline.
Stay social. Get together with loved ones, volunteer or take a class. For more ideas, read: 10 Ways to Combat Loneliness When You Have No One to Fall Back On.
3. Listening to Loud Music
Believe it or not, blasting your headphones might be harming your brain.
Indeed, extended exposure to loud noise can change how the brain processes speech, according to a small animal study in the November/December 2014 issue of Ear and Hearing. The researchers noted that noise-induced hearing loss may affect the brain’s recognition of speech sounds.
While this research was done in animals, it may have important implications for humans as well. That’s because hearing loss over time has been linked to dementia, Dr. Jandial says.
Dial down the decibels. You can still enjoy your favorite tunes at a toned-down volume.
Sounds up to 70 dBA are generally considered safe, while sound at or above 85 dBA is more likely to damage your hearing over time. (FYI: Most iPhones have a noise level measurement feature; for other devices, you can download an app like Sound Meter.)
4. Not Sleeping Enough
A whopping third of American adults don’t get the recommended seven hours of sleep. When you don’t log enough pillow time, it taxes your brain.
In fact, a September 2018 study in Sleep concluded that cognitive performance — including memory, reasoning, problem-solving and communications skills — is impaired in people who usually sleep fewer than seven or more than eight hours per night.
Make sleep a priority: Keep a consistent bedtime schedule and ditch the distractions. Regular exercise, deep breathing and meditation can also help improve sleep quality too.
From cancer to heart disease and lung-related illnesses, smoking ravages virtually every organ of the body. And you can add your brain to that list.
“Smoking damages the lining of blood vessels and can lead to narrowing, which can cause reduced blood flow to the brain,” Dr. Jandial says. Again, the less oxygenated blood that bathes your brain, the fewer fundamental nutrients it receives.
It’s never too late to nix an unhealthy habit. Here are the seven most effective strategies to quit smoking.
6. Eating Too Much Sugar
Hate to break it to you: Your sweet tooth could have a negative effect on your noggin.
And in humans, you can clearly see the consequence of excessive sugar on the brains of people with diabetes, a disease characterized by chronically high blood glucose levels. High blood sugar can affect the brain’s functional connectivity, shrink the brain or cause small-vessel disease, which inhibits blood flow in the brain, leading to cognitive difficulties, per Harvard Medical School.
Monitor your intake of added sugar by reading food labels. Males at birth should get no more than 9 teaspoons of added sugar per day while females should stick to 6 teaspoons.
7. Getting Too Much Sodium
Sprinkling too much salt on your food isn’t in your brain’s best interest.
Excessive sodium is associated with health problems like high blood pressure. And the effects of chronic hypertension include reduced blood flow to the brain, making your brain more vulnerable to atrophy and cognitive impairment, according to a June 2014 Neurology study.
Skip the saltshaker and limit high-sodium foods.
8. Drinking Too Much Alcohol
Your frequent happy hour habit might be hindering your brain health. In addition to temporary effects like blurred vision, slurred speech and slowed reaction times, heavy drinking can increase your risk of developing more serious, permanent changes in the brain, according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA).
Indeed, long–term heavy alcohol use may shrink the brain and cause deficiencies in the brain’s white matter, the fibers that transport information between the gray matter.
Curb your cocktail intake. Males should stick to a maximum of two drinks per day while Females should have no more than one.

This is very important. I didn’t know that sitting can affect my brain.
Thanks for sharing.
