A sharp mind, stable mood, and strong memory all depend on one key process, neurogenesis, the growth of new brain cells. While it was once believed that brain cells couldn't regenerate, science now shows otherwise.
The exciting news?
You can boost neurogenesis naturally, especially through exercise. Find the six powerful types of physical activity that not only benefit your body but also help build a better, brighter brain.

What Is Neurogenesis and Why Does It Matter?
Neurogenesis refers to the formation of new neurons in the brain. This process is vital for learning, memory, and emotional regulation.
The hippocampus, a region associated with memory and learning, is one of the primary areas where neurogenesis occurs. Enhancing neurogenesis can lead to improved cognitive abilities and emotional resilience.
Does Exercise Increase Neurogenesis?
Yes, exercise plays a significant role in promoting neurogenesis. Physical activity increases the production of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and survival of neurons.
Regular exercise also improves blood flow to the brain, delivering oxygen and nutrients essential for neuronal health.

What Are the Best Exercises to Grow New Brain Cells?
Certain exercises are particularly effective in stimulating neurogenesis. These include aerobic activities like running and swimming, resistance training, walking, high-intensity interval training (HIIT), and mind-body practices such as yoga and meditation. Incorporating a variety of these exercises into your routine can maximize brain cell growth.
How Does Aerobic Exercise Support Neurogenesis?
Aerobic exercises, such as running and swimming, elevate heart rate and increase blood circulation, delivering more oxygen to the brain.
This enhanced blood flow stimulates the production of BDNF, promoting the growth of new neurons. Regular aerobic activity has been linked to improved memory and cognitive function.
Can Resistance Training Stimulate Brain Cell Growth?
Resistance training, including weight lifting and bodyweight exercises, contributes to neurogenesis by increasing levels of BDNF and other growth factors.
This form of exercise also reduces inflammation and oxidative stress, creating a favorable environment for neuron development.
Is Walking Enough to Promote Neurogenesis?
Walking, especially at a brisk pace, can effectively stimulate neurogenesis. It is a low-impact aerobic exercise that increases blood flow and BDNF levels. Regular walking has been associated with improved memory and reduced risk of cognitive decline.
How Does High-Intensity Interval Training (HIIT) Affect Brain Plasticity?
HIIT involves short bursts of intense activity followed by rest periods. This training method significantly boosts BDNF production and enhances brain plasticity, the brain's ability to adapt and reorganize itself. HIIT has been shown to improve cognitive functions such as attention and memory.

Does Yoga or Meditation Help with Neurogenesis?
Yoga and meditation are mind-body practices that reduce stress and increase BDNF levels.
These activities promote relaxation and mental clarity, supporting the growth of new neurons. Regular practice can lead to improved emotional regulation and cognitive performance.
How Often Should You Exercise to Boost Neurogenesis?
Engaging in physical activity most days of the week is beneficial for neurogenesis. Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week, combined with strength training sessions twice a week.
When Is the Best Time to Exercise for Brain Health?
Exercising in the morning may offer cognitive benefits throughout the day, enhancing focus and alertness. However, the most important factor is consistency. Choose a time that fits your schedule to maintain a regular exercise routine.
What Lifestyle Habits Support Neurogenesis Beyond Exercise?
In addition to physical activity, other habits can support neurogenesis:
-
Nutrition: Consuming a diet rich in antioxidants, omega-3 fatty acids, and flavonoids supports brain health.
-
Sleep: Adequate sleep is essential for memory consolidation and neuron growth.
-
Mental Stimulation: Engaging in learning activities and challenging the brain promotes neurogenesis.
-
Stress Management: Reducing stress through relaxation techniques helps maintain a healthy environment for neuron development.
What Inhibits Neurogenesis? (Stress, Alcohol, Poor Sleep)
Several factors can hinder neurogenesis:
-
Chronic Stress: Elevated cortisol levels from prolonged stress can damage the hippocampus and inhibit neuron growth.
-
Alcohol Consumption: Excessive alcohol intake negatively affects brain structure and function.
-
Sleep Deprivation: Lack of sleep impairs memory and reduces the production of new neurons.
What Is the Link Between Neurogenesis and Mental Health?
Enhanced neurogenesis is associated with improved mood and reduced symptoms of depression and anxiety. By supporting the growth of new neurons, individuals may experience better emotional regulation and resilience to stress.

Benefits of Exercise for Neurogenesis
-
Increases production of Brain-Derived Neurotrophic Factor (BDNF): BDNF supports neuron growth and survival.
-
Enhances memory and learning ability: Exercise improves cognitive functions.
-
Improves mood and reduces anxiety: Physical activity releases endorphins and reduces stress hormones.
-
Supports long-term brain plasticity: Regular exercise maintains the brain's adaptability.
-
May delay age-related cognitive decline: Staying active helps preserve cognitive functions with age.
Conclusion
Incorporating various forms of exercise into your routine is a powerful strategy for enhancing neurogenesis and overall brain health.
Activities like aerobic workouts, resistance training, walking, HIIT, yoga, and meditation not only improve physical well-being but also support the growth of new brain cells.
By maintaining a consistent exercise regimen and adopting supportive lifestyle habits, you can promote cognitive function and emotional resilience throughout your life.

FAQs
What exercise is best for growing new brain cells?
Aerobic exercises such as running, swimming, and cycling are highly effective in stimulating neurogenesis due to increased BDNF production.
How long does it take for neurogenesis to occur?
Neurogenesis is an ongoing process, but significant changes in neuron growth and cognitive function can be observed after several weeks of consistent exercise.
Can you really regrow brain cells through exercise?
Yes, regular physical activity promotes the growth of new neurons, particularly in the hippocampus, enhancing memory and learning.
Does neurogenesis decline with age?
While neurogenesis naturally slows with age, engaging in regular exercise and maintaining a healthy lifestyle can mitigate this decline.
Are there supplements that help promote neurogenesis?
Certain supplements, such as omega-3 fatty acids and flavonoids, may support neurogenesis. Consult with a healthcare provider before starting any new supplement regimen.
What foods promote brain cell growth?
Foods rich in antioxidants, omega-3s, and flavonoids, like berries, fatty fish, and dark chocolate—can support neurogenesis.
Can meditation and mindfulness increase neurogenesis?
Yes, these practices reduce stress and increase BDNF levels, promoting the growth of new neurons. Learn more about neuropsychiatric diseases.
How does stress impact neurogenesis?
Chronic stress elevates cortisol levels, which can damage the hippocampus and inhibit the formation of new neurons.
Is neurogenesis possible after brain injury?
While brain injuries can impair neurogenesis, rehabilitation and certain therapies may help stimulate neuron growth and recovery.
How do I know if my brain is creating new neurons?
While direct measurement is challenging, improvements in memory, mood, and cognitive function may indicate enhanced neurogenesis.
