Does prioritizing your fitness help protect your brain health?
We all want to protect our brains and bodies from disease and decline and stay sharp and vibrant throughout the decades. Regular exercise is part of a healthy lifestyle, and it brings a range of benefits, from lowering blood pressure to perking up your mood and prompting the release of feel-good endorphins. Your training habits can benefit your physical health and your brain health, too. For example, an interesting study showed that people who took part in aerobic fitness training had increased brain volume and white and gray matter.
Physical activity can sharpen problem-solving, memory, and learning and reduce depression or anxiety. Another study concluded that cognitive decline is nearly twice as common in adults who are inactive compared to active adults. In a recent study, researchers wanted to look at how exercise lowered the risk of dementia. Let’s take a look at the study and the results.
The study
In a study published in the British Journal of Sports Medicine, the researchers wanted to investigate how cardiorespiratory fitness affected the risk of dementia, taking genetic predisposition into account. The researchers looked at data from 61,214 adult participants who didn’t have dementia.
The researchers identified dementia cases through medical records and assessed genetic predisposition. They used a six-minute submaximal cycling test to determine the participants’ cardiovascular fitness and estimate maximal oxygen consumption or VO2 max. The participants also took neuropsychological tests to evaluate their reaction time, processing speed, and memory. The researchers looked closely at the data to analyze the relationship between cardiovascular fitness and genetic predisposition.
The results
In conclusion, the researchers reported a positive association between a high cardiovascular fitness level and cognitive function across all age groups. High cardiovascular fitness levels were associated with a 40% lower overall risk of dementia and a delayed dementia onset by 1.48 years on average. For individuals with a high predisposed risk of dementia, high cardiovascular fitness was associated with a 35% lower risk of dementia.
What is cardiovascular fitness?
Cardiovascular fitness refers to your ability to deliver oxygen to your working muscles and your heart. Another interesting study revealed that higher cardiovascular fitness levels were linked with a lower risk of heart and blood vessel disorders and complications.
What we can learn from this research
This research shows that having good fitness levels could lower your risk of dementia, delay its onset by up to 18 months, and enhance your cognitive performance. This study shows us that even those with a higher genetic risk of developing dementia can lower that risk with regular exercise. Prioritizing your fitness helps protect your brain health, heart health, and more.

Fitness coach says ‘just cardio isn’t enough’; shares 1 exercise women over 35 must do to stay strong and healthy
As we age, our bodies naturally start losing muscle mass and bone density, which can affect strength, metabolism, and overall health. Many women over 35 notice changes in energy levels, weight distribution, and endurance, making it essential to adopt exercises that not only tone but also strengthen the body.
Tara LaFerrara, fitness coach and personal trainer, shares in her September 22 Instagram post why women over 35 should start incorporating strength training into their routines and how it can transform both body and health.

Why does muscle loss matter after 35
If you are a woman over 35 and not doing any sort of strength training, Tara warns you’re in for a rude awakening. “I’m talking the moment that your body starts to slow down, get weaker, and feel like you hurt more,” she shares.
“It is not just ageing, it is muscle loss, and it starts way earlier than you think. After the age of 35, we start losing muscle every single year. And that muscle is so important because it is your metabolism, your bone density, your energy, and just the ability to bounce back when life throws things at you,” says Tara.
Can cardio and pilates alone keep you strong
She emphasises that cardio and Pilates alone aren’t enough. “You need to lift, squat, push, pull, and press. It’s not about getting bulky and muscular, it’s about getting strong enough to handle ageing on your own terms.”
Her advice is simple: “So if you’re tired of feeling like your body is working against you, start working with it. Pick up some weights. Your future self will thank you.”
Strength training after 35 isn’t just about aesthetics; it’s about maintaining health, mobility, and resilience. As Tara highlights, incorporating resistance exercises into your routine is one of the best ways to support your body through the natural changes that come with age.

New Year’s Fitness Resolutions Start with Healthy Sleep | Newswise
Newswise — As the New Year approaches, many Americans are setting fresh intentions to eat better and move more — and new data show those habits may deliver an unexpected bonus: better sleep. According to a new survey from the American Academy of Sleep Medicine, 59% of adults say eating a well-balanced diet helps them sleep slightly or significantly better. Staying active throughout the day may also help improve sleep. According to the survey, adults say exercising in the morning (42%) or evening (46%) helps them sleep slightly or significantly better.
“Sleep is one of three pillars of a healthy lifestyle, including eating a well-balanced diet and incorporating regular physical activity,” said AASM spokesperson Dr. Kin Yuen. “When people make New Year’s resolutions or select their ‘nudge word’ for the year, they often prioritize diet and exercise. These changes don’t just support physical health—they also improve sleep.”
The findings suggest that New Year’s resolutions don’t need to be isolated goals. Improving one aspect of health, whether diet, exercise, or sleep, can create positive ripple effects across all three areas of wellness. This is especially true for younger adults, with those 25-34 being the most likely age group to say a well-balanced diet (64%) or exercise in the evening (60%) helps them sleep better.
“Sufficient sleep significantly reduces the risk of chronic illnesses, such as obesity, heart disease, and even depression and anxiety,” said Yuen. “Whether you’re improving your diet, increasing your activity level, or managing stress, prioritizing sleep gives you the energy and mental clarity needed to start the year strong.”
Here are some tips from the AASM on how to develop healthy sleep habits and reap all the benefits of your New Year’s resolutions:
- Create a consistent bedtime routine — Make sure you are giving yourself enough time to get the recommended seven or more hours of sleep per night.
- Make time in your daily routine for physical activity — Pick physical activities that you enjoy and that match your abilities.
- Eat a well-balanced diet — Try to meet the recommended daily servings of fruits and vegetables, grains, and protein.
- Disconnect from devices at night — Turn off all electronics at least 30 minutes to an hour before your bedtime to help prepare for sleep.

About the Survey
The American Academy of Sleep Medicine commissioned an online survey of 2,007 adults in the U.S. The overall margin of error fell within +/- 2 percentage points with a confidence interval of 95 percent. Fieldwork took place between June 5-13, 2025, by Atomik Research, an independent market research agency.
