The Link Between Exercise and Brain Health: How to Boost Cognitive Function


As we age, our cognitive abilities start to decline, making it harder for us to remember things, process information quickly, and make decisions. However, research has shown that regular exercise can improve cognitive function and reduce the risk of developing age-related cognitive decline and dementia. In this article, we’ll explore the link between exercise and brain health and provide practical tips on how to boost cognitive function through exercise.

The Science of Exercise and Brain Health

How Exercise Affects the Brain

When we exercise, our heart rate increases and more blood is pumped to our brain, delivering oxygen and nutrients that help to nourish our brain cells. Exercise also triggers the release of various hormones, including endorphins, which can improve our mood and reduce stress and anxiety. Furthermore, exercise stimulates the production of brain-derived neurotrophic factor (BDNF), a protein that helps to promote the growth and survival of brain cells and enhances the connections between neurons, resulting in improved cognitive function.

Types of Exercise That Benefit Brain Health

While any form of physical activity can provide benefits for brain health, some types of exercise may be more effective than others. Aerobic exercise, such as running, cycling, and swimming, has been shown to improve cognitive function and reduce the risk of dementia. Resistance training, such as weight lifting and bodyweight exercises, can also benefit brain health by increasing muscle strength and improving balance and coordination, which are essential for maintaining mobility and preventing falls in older adults.

How Much Exercise Is Needed to Boost Cognitive Function?

The optimal amount of exercise needed to improve cognitive function is still unclear and may vary depending on the individual’s age, fitness level, and other factors. However, some studies suggest that engaging in moderate-intensity exercise for at least 30 minutes per day, five days per week, can provide significant benefits for brain health.

Practical Tips for Boosting Cognitive Function Through Exercise

Start Slowly and Gradually Increase the Intensity

If you’re new to exercise or haven’t been active in a while, it’s essential to start slowly and gradually increase the intensity and duration of your workouts. This approach can help to prevent injuries and ensure that you don’t get discouraged or overwhelmed by the demands of exercise.

Mix Up Your Workouts

To maximize the benefits of exercise for brain health, it’s crucial to vary your workouts and include a mix of aerobic and resistance exercises. This approach can help to target different muscle groups and keep your workouts challenging and engaging.

Make Exercise a Habit

One of the most effective ways to ensure that you get the benefits of exercise for brain health is to make it a regular habit. Try to schedule your workouts at the same time each day or week, so that it becomes a part of your routine.

Get Support from Others

Exercising with a friend or family member can be a great way to stay motivated and accountable. Consider joining a fitness class or group, or using a workout app or online community to connect with others who share your fitness goals.


Regular exercise can be a powerful tool for maintaining and improving cognitive function, reducing the risk of age-related cognitive decline and dementia, and promoting overall health and well-being. By incorporating a mix of aerobic and resistance exercises into your routine, starting slowly and gradually increasing intensity, making exercise a habit, and getting support from others, you can reap the many benefits of exercise for brain health.
