Can Exercise Improve Your Memory? Here’s What Science Says
Regular physical exercise supports brain health by increasing blood flow, encouraging new neural connections, and helping improve memory, focus, and emotional resilience.
Research shows that staying active strengthens the link between exercise and brain health, fueling neuroplasticity and supporting emotional regulation. Regular movement not only increases blood flow to the brain but also stimulates the release of neurotransmitters that play a key role in focus, memory, and emotional stability1,2
In this article, we’ll explore what science says about the connection between physical activity and cognitive performance, highlight the types of workouts with the biggest brain benefits, and share practical tips for making movement a lasting part of your routine.
What Does Exercise Do for the Brain? How Physical Activity Supports Brain Health
Physical activity improves circulation, helping maintain steady blood flow so your brain gets the oxygen and nutrients it needs. This in turn supports neuroplasticity, allowing the brain to adapt and create new connections necessary for learning and problem-solving.3,4
Exercise also triggers the release of essential neurotransmitters such as dopamine, serotonin, and norepinephrine. These chemical messengers help regulate your mood, improve your focus, and boost your motivation.5,6
Additionally, regular movement encourages the production of brain-derived neurotrophic factor (BDNF), a protein that helps generate new neurons and strengthens existing ones. Higher BDNF levels are linked to sharper memory, faster learning, and better cognitive flexibility, making consistent movement one of the most effective ways to support long-term brain health.7
How Physical Activity Supports Your Mental Health
Feeling stressed or mentally drained can seriously impact your ability to think, stay focused, and manage your emotions. Physical activity supports your mental health by lowering stress hormones, releasing mood-enhancing chemicals, and activating the body’s relaxation response.
Exercise supports stress management in a few different ways. While cortisol naturally rises during more intense activity, research shows that people who exercise consistently tend to have lower baseline cortisol levels over time. Regular movement also boosts neurotransmitters like endorphins and norepinephrine, which help ease tension, lift mood, and support a calmer, more focused state of mind.5,8
According to the American Psychological Association(APA), many experts believe that regular exercise can be as effective as antidepressants in reducing symptoms of anxiety and depression. Activities like walking, yoga, and strength training have been shown to improve mood and ease anxiety. Whether it’s a brisk jog or a calming stretch session, movement helps activate the parasympathetic nervous system, shifting the body from a state of stress to a state of relaxation.9,10
Consistency, however, is key because the benefits build over time. Find activities you genuinely enjoy, and switch them up now and then to keep them fresh. Exercising with others can also provide social support, which may help reduce depression.10
What Are the Cognitive Benefits of Exercise?
Regular physical activity strengthens your body and your brain. Some of the most powerful cognitive benefits include:
- Improved Memory and Learning: Aerobic exercise (like running or cycling) stimulates the hippocampus, enhancing memory and supporting learning over time.11,12
- Better Focus and Attention: Even short bouts of moderate exercise boost blood flow and key neurotransmitters like dopamine and norepinephrine, improving concentration and mental alertness.2,13
- Greater Mental Resilience: Staying active builds discipline, perseverance, and coping skills. Over time, regular exercise helps your brain respond more effectively to stress and supports emotional stability.14,15
- Better Emotional Regulation: Regular exercise helps balance mood-regulating brain chemicals such as serotonin and endorphins. This supports emotional stability, strengthens coping skills, and reduces the impact of everyday stressors.5,8,13
- Supports Long-Term Brain Health: Regular exercise helps maintain brain structure, strengthen neural connections, and support overall cognitive function over time.2,11,16
What Exercise is Best for Your Brain?
Different types of exercise provide unique cognitive benefits, each supporting brain health in various ways. From improving memory and focus to lowering stress and boosting overall mental resilience, incorporating a variety of exercises into your routine can significantly support your cognitive health.
Aerobic Exercise
Walking, running, cycling, and swimming all get your heart pumping and deliver more oxygen to your brain. This increased circulation promotes neuroplasticity, encourages new neural connections, and helps preserve brain structure. While aerobic exercise can create a brief, normal rise in inflammatory markers during and right after activity, consistent aerobic exercise is associated with lower long-term inflammation and supports overall brain health. It also supports memory, boosts attention, and enhances processing speed.13,17,18
Strength Training
Lifting weights or using resistance bands boosts blood flow and supports the growth of new neural connections. Research shows it can sharpen key executive functions like working memory, focus, and cognitive flexibility. Over time, it may help preserve brain structure, including regions like the hippocampus that are important for memory. By also reducing inflammation over time and supporting metabolic health, strength training helps keep your brain healthy and adaptable, especially when paired with regular aerobic activity.18,19,20
High-Intensity Interval Training (HIIT)
HIIT training alternates bursts of challenging exercise with short recovery windows, challenging both the body and the mind. These quick, intense intervals enhance mental alertness, boost energy levels, and increase blood flow and oxygen delivery to the brain. Studies show that HIIT supports executive function, helping with better decision-making, problem-solving, and cognitive flexibility.21,22,23
Yoga and Mindfulness Practices
Yoga and mindfulness techniques work together to calm the body and focus the mind. Gentle movement, controlled breathing, and meditation help reduce stress hormones and improve emotional regulation. Consistent yoga or mindfulness training has been linked to reduced anxiety, enhanced mood, and improved resilience.24,25
Tips for Making Exercise a Habit for Long-Term Mental Well-Being
The key to maintaining cognitive and emotional benefits from exercise is consistency. Here’s how to make it a sustainable habit:
- Find Enjoyable Activities. Choose workouts you love to keep your motivation high. Enjoyment is key to consistency. Whether dancing, swimming, or hiking, finding a physical activity you look forward to will make it easier to stay committed.
- Set Realistic Goals Start with short sessions and gradually increase intensity. Setting small, achievable milestones, such as a 10-minute walk daily, creates a sense of accomplishment and builds momentum toward long-term fitness habits.
- Make It a Daily Ritual. Incorporate movement into your daily routine, such as taking the stairs or walking during breaks. Tying exercise to existing habits, like stretching while watching TV or walking after meals, becomes a natural part of your routine rather than an obligation.
- Stay Accountable. Partner with a friend or join a community for encouragement. Having a workout partner or joining a fitness group helps with motivation, accountability, and enjoyment, making it more likely that you’ll stick to your exercise plan.
Take the First Step Toward Better Brain Health
The effects of exercise on the brain go far beyond physical fitness. Movement helps fuel cognitive function, reduces stress, and enhances mental clarity, making it a powerful tool for overall well-being. Incorporating consistent physical activity into your routine helps support brain health and cognitive functions.
