As women reach their mid-40s and beyond, many begin to focus more on staying healthy—not just physically, but mentally. And with good reason: Alzheimer’s disease disproportionately affects women, with nearly two-thirds of all cases being women. While factors like genetics and age play a significant role, the good news is that certain lifestyle changes, including fitness, can significantly reduce the risk of developing Alzheimer's and other forms of dementia.
The Connection Between Exercise and Brain Health
Physical activity is one of the most powerful tools you have for maintaining brain health. Research shows that exercise increases blood flow to the brain, reduces inflammation, and promotes the production of chemicals that support brain cell health, like Brain-Derived Neurotrophic Factor (BDNF). BDNF acts like fertilizer for your brain, helping new neurons grow and protecting existing ones, which may prevent or delay cognitive decline.
For women 45 and older, this means that exercise is not only essential for keeping your body in shape but also for keeping your brain sharp. But not all exercise is created equal. Let’s explore the best kinds of workouts to promote both physical and cognitive wellness.
1. Strength Training for Brain Power
Strength training, also known as resistance training, is a game-changer for women over 45. Not only does it help build muscle and improve bone density, which is vital as estrogen levels drop during menopause, but it’s also linked to better brain health. Studies have shown that strength training can improve memory and cognitive function, possibly because it increases levels of BDNF.
What to Do:
Incorporate strength training exercises like squats, lunges, and weightlifting into your weekly routine. Aim for two to three sessions per week. You don’t need to lift heavy weights—bodyweight exercises or light dumbbells can be just as effective for promoting brain health.
2. Cardio for a Healthy Heart and Brain
Cardiovascular exercise is often thought of as essential for heart health, but it’s just as crucial for your brain. Aerobic exercise, like brisk walking, swimming, or cycling, improves blood flow and oxygen delivery to the brain, which helps clear away toxins and reduce brain inflammation.
According to Dr. Peter Attia, maintaining good cardiovascular fitness can lower your risk of Alzheimer’s. Specifically, improving your VO2 Max—your body’s ability to use oxygen—has been linked to better cognitive function. Attia recommends incorporating moderate to high-intensity cardio into your weekly exercise routine to optimize both heart and brain health.
What to Do:
Aim for at least 150 minutes of moderate-intensity cardio each week. Walking, jogging, or dancing are fun, easy ways to keep your heart pumping. If you’re up for a challenge, try incorporating interval training, which alternates between periods of intense effort and rest, for an extra boost.
3. Yoga and Mindfulness for Stress Reduction
Chronic stress can damage your brain, particularly the hippocampus, which is responsible for memory. Activities like yoga, tai chi, or even simple meditation can help lower cortisol levels, reduce stress, and improve brain health.
Yoga is particularly beneficial for women over 45 as it not only reduces stress but also improves flexibility and balance, which are crucial as we age. Plus, certain types of yoga, like Vinyasa or Power Yoga, can offer a decent cardio workout as well.
What to Do:
Incorporate yoga or meditation into your weekly routine. Even just 10 minutes of mindfulness practice can lower stress levels and boost your cognitive function. Try a calming yoga class once or twice a week, and combine it with daily mindfulness or breathing exercises to reduce mental and emotional strain.
4. Staying Active Outside the Gym
Beyond formal exercise, staying physically and mentally active throughout the day can significantly reduce your risk of cognitive decline. Activities like gardening, dancing, or even socializing with friends have been shown to improve cognitive function and delay the onset of dementia.
What to Do:
Find activities that bring you joy and incorporate them into your daily life. Whether it’s taking a dance class, joining a walking group, or trying new hobbies like knitting or painting, keeping your brain engaged with new challenges is just as important as structured workouts.
Final Thoughts: A Balanced Approach for Lifelong Brain Health
For women over 45, preventing Alzheimer's involves more than just keeping fit—it requires a holistic approach to wellness. By integrating strength training, cardiovascular exercise, mindfulness practices, and cognitive stimulation into your routine, you’ll not only enhance your physical health but also safeguard your brain for years to come.
As we age, it’s crucial to stay active, both physically and mentally. The steps you take now can have a lasting impact on your brain health, helping you stay sharp and enjoy life to the fullest.
