How to Slow Brain Aging

When most people think about aging, they imagine a linear progression towards an inevitable end. They think in terms of birthdays, knowing that the more candles on the cake, the more we should anticipate things like joint pain, lines on the face and even foggy thinking. Yet the most recent research shows us that we have the story all wrong around brain health. The brain changes we associate with aging (for example, memory loss) are far more dynamic and modifiable through the choices we make each day than people realize. Here’s how you can help slow brain aging and protect your brain right now.

What is “brain aging”?

While most people count their age in birthdays, our bodies don’t see time in the same way. In fact, research shows us that each organ in our body ages at a different biological rate (this is called “biological age”), and this predicts our risk for having issues with those organs more than our age in birthdays. For example, having a biologically older liver correlates with dramatically higher rates of liver disease. Specific to this conversation, having a biologically older brain (as measured using MRI and other tests) is strongly linked to risk for cognitive impairment, dementia and even conditions like multiple sclerosis. While there are many specifics, brain aging on imaging is usually linked to the rate of brain tissue loss (atrophy).

Can we slow brain aging?

Unlike our age in birthdays, we can absolutely take steps to positively influence our rate of biological aging. Research just published in the last few years demonstrates that certain lifestyle factors are strongly linked to the speed with which our brains age, and a recent diet study even showed that adopting a specific food pattern was linked to a slower rate of brain aging. While we may not be able to stop our brains from aging, this science points to powerful strategies to help combat more rapid aging. Here are four of the most important to prioritize today.

1. Eat the right diet

Every bite of food is information that programs brain structure and function. According to a study just published, lower diet quality between childhood and adulthood is linked to a higher risk for developing dementia. Multiple previous studies have also demonstrated that eating a healthy diet akin to the Mediterranean or MIND diet patterns could reduce dementia risk, and that higher diet quality is linked to larger brain volumes. However, there’s also some interventional data suggesting a protective effect on brain aging.

In an18 month study on 284 people published in 2022, researchers found that people assigned to either a Mediterranean diet or a Mediterranean diet plus additional sources of plant molecules called polyphenols demonstrated slower rates of brain atrophy, with the biggest benefit seen in the group consuming the most polyphenols. Beyond consuming a diet rich in fiber, healthy fats, fruits and vegetables and polyphenols and low in processed foods, research also suggests that avoiding excess alcohol is a powerful way to prevent rapid brain aging.

2. Exercise regularly

It’s been well documented that regular exercise can help boost and protect brain function. As just stated in The Lancet “…regular physical activity, high cardiorespiratory fitness (CRF), or a combination of both, can mitigate cognitive impairment and reduce dementia risk.” Beyond this, exercise may even be able to reverse brain aging. In a stunning 2011 study, researchers found that a regular exercise program grew the brain’s memory center (the hippocampus), “effectively reversing age-related loss in volume by 1 to 2 y.” Equally impressive was a just published stud showing that 12 months of exercise effectively lowered people’s relative brain age. There’s lots of nuance and specifics to uncover here, but engaging in at least 150 minutes of moderate intensity exercise along with 2-3 days of resistance training a week should be a goal for all who can manage it.

3. Avoid air pollution

One of the most compelling recent areas of brain research concerns the link between environmental exposures and brain health outcomes. Though largely marginalized as a topic of podcasts and popular health conversations, the brain risk posed by air pollution is starting to gain more recognition. For example, a new article published in Stroke  demonstrated that even lower exposure to tiny PM 2.5 air pollutants was linked to brain atrophy in older adults with good brain function. A recent mouse study found exposure to the same pollutants led to brain atrophy. Importantly, research also suggests that improving air can help counter some of these effects. In a 2024 study in Environment International, researchers found that when air pollution levels dropped, brain function improved, as did an imaging marker of brain health.

4. Focus on sleep quality

It is impossible to overstate the importance of sleep for brain health. Better sleep is linked to improved focus, cognition, mental health and lower risk for a host of brain diseases. Yet the extent to which this correlates with brain aging has only recently been explored. In a 2025 paper in eBioMedicine, researchers compared sleep quality scores with inflammation and brain aging in nearly 28,000 adults. People reporting lower quality sleep were found to have higher brain ages, and inflammation appeared to help explain the association.

The effect of sleep on brain aging may be far more rapid (and reversible) than other variables. A powerful 2023 paper in The Journal of  Neuroscience used MRI to gauge brain aging after 24 hours of sleep deprivation, finding an increase in brain age of 1-2 years that was reversed after participants were allowed a night of recovery sleep. While better sleep hygiene practices can dramatically improve sleep quality, it’s important to recognize that treatable sleep disorders like obstructive sleep apnea often go undiagnosed, so consider speaking to your health practitioner about a sleep evaluation if sleep quality is a major challenge.

Study Finds Social Relationships Better Brain Aging

Who are the SuperAgers? They are men and women over 80 years of age, whose memories are as good – if not better – than people 20-30 years their juniors. In a recent study conducted by researchers from Northwestern University, a group of seniors was examined throughout 9 years. 

Every couple of years, they had to fill out surveys about their lives and undergo neuropsychological tests, brain scans, and a neurological examination, among other evaluations.

Good Friends Make a Difference in Brain Aging

When compared to their “normal” peers, SuperAgers were found to have some distinctive brain features: thicker cortices, larger anterior cingulate (a part of the brain important to attention and working memory), and resistance to age-related atrophy (degeneration of cells). But it was obvious to the researchers there are other factors involved as well.

In order to find attributes SuperAgers have in common and characterize them, 31 SuperAgers and 19 “normal” seniors were asked to fill out a questionnaire regarding their psychological well-being. It became clear that SuperAgers had another distinct common feature other than their brain structure: they all cultivated warm, satisfying and trusting relationships.

How Do They Maintain Relationships?

When interviewed, the senior citizens who took part in the research spoke of maintaining friendships that go as far back as high school or joining clubs and groups that help them stay active and socialize. For example, a woman of 103 years living in Illinois reported that she makes frequent calls and visits to her long-time friends, even those who now suffer from Alzheimer’s or those that are no longer able to leave their house. She is also a prominent figure in her retirement community – she’s on the team that welcomes new residents, and she makes an effort to make everyone feel at home and included.

Another SuperAger in the study had helped in founding a men’s group, Men Enjoying Leisure, which has grown and expanded to have several branches around Chicago’s suburbs. Every month, the group meets for two hours to discuss personal issues, such as health, family matters and more. This platform is very important, especially for men who might be less inclined to talk about their feelings and bottle things up. Knowing you are not alone in the problems you face is a big benefit one gets from social relationships.   

The Link Between Social Relationships and Cognition

One scientific explanation as to why positive relationships make humans function better, is that they help calm our stress response system. Chronically high levels of the stress hormone cortisol can have a devastating effect on physical and emotional health – weight gain, slow healing injuries and more.

A different study of elderly residents in Hong Kong showed that those who cultivate supportive relationships had a significant drop in cortisol levels during the day. The human brain is more adaptive than some might think. The older we get, what’s lost in quick-recall and short term memory is balanced by the ability to reflect and hold multiple perspectives, according to experts. This means that neurological changes in an aging brain may contribute to emotional regulation and an increased ability to relate compassionately to others. 

Humans are a social animal. Friendships are important at any age for our mental well-being, but it seems we also physically need one another in order to age better.

7 Easy Habits that Boost Our Health

The body is an incredibly complex machine, attune to every little thing we do, eat or experience. We may not be aware of it, but we impact our health in myriad ways every day. Here are 7 things we may do, without even noticing, that have surprising medical and mental benefits, making you want to repeat them a whole lot more. 

1. Singing

When we sing, our brain releases hormones and endorphins that contribute to lowering our mental stress and anxiety, as well as reducing physiological pain. Studies on the subject found that singing contributes to lowering our blood pressure, increasing our cognitive abilities, strengthening the immune system and improving our memory. Various studies even found that singing helps the medical situation of Parkinson patients, improving their balance, their vocal abilities and their ability to swallow.

2. Crying

Crying is seen as a weakness by most. Something negative that shouldn't happen. But crying also has its unique advantages. When we cry, our body dumps the cortisol hormone, which causes an increase in our mental stress. By crying, we may be preventing issues such as insomnia, anxiety and weight gain. Crying even helps strengthen our immune system. The tears we shed also have a purpose and kill over 90% of the bacteria in the eyes and other toxins found on the face. They also prevent our eyes from drying out.

3. Kissing

Kissing is a natural remedy for headaches or menstrual pain, thanks to the dilating of blood vessels that occur during a kiss, which helps lower our blood pressure. A study on the subject has shown that a large amount of saliva secreted during a kiss helps the body fight gingivitis. When kissing we also operate rarely-used muscles in our neck and face that help tone them and slow down the aging process in these areas. So pucker up!

4. Creative writing

Believe it or not, creative writing is really good for you. It enhances your cognitive abilities, your memory, and your mental strength. A new study on the topic unveiled that creative writing, especially the kind that described our deepest thoughts and emotions, gives us a relief from physical pain. Researchers explained that the writing caused a reduction in hormone secretion, especially for hormones like cortisol that elevate our blood pressure and weaken our immune system.

 5. Courtesy

Good manners aren't just good manners, they're healthy manners! When we are kind to those around us we release a hormone in our body called oxytocin, which makes chemicals that expand the blood vessels, thus reducing blood pressure and improving the overall health of the heart and the blood vessels. The hormone also fights free radicals in our blood system and so slows down the aging process of our internal organs.

6. Laughter

We all know that laughter is the best medicine, and it's astounding how many studies back that up. Laughter lowers our blood pressure, reduces our risk of stroke, reduces our mental stress and takes care of our heart. Laughter is also a great workout for our stomach muscles and even strengthens the white blood cells that play such an important role in our immune system.

7. Spending time with friends and family

It may sound sappy, but loneliness has been found to be no less detrimental to health than regularly smoking. Many studies have pointed to a strong relationship between good relations with friends and family and sleeping well better concentration and mental abilities and a stronger immune system. According to one of the studies on the subject, strong ties to family and friends can raise your chance of longevity by as much as 50%.
