11 Surprising Mental Benefits of Exercise

Did you know that just 30 minutes of physical activity a few times a week can reduce symptoms of depression by up to 40%? This research was carried out on 1.2 million people in the U.S and showed that exercise changes the brain structure and function.

According to self-reported data from the Center for Disease Control and Prevention’s Behavioural Risk Factor Surveillance System survey, the average person has 3.4 mental health days per month. This provides a valuable population-level indicator of the mental health burden in the U.S.

The physical benefits of exercise are already well established. However, according to the World Health Organisation, health is not just the absence of disease; it includes physical, mental, and social well-being. This means we must give just as much attention to our mental health as we do to our physical health, and understanding how exercise supports both is an essential part of it.

In this article, we will explore the relationship between mental health and exercise and unravel the many benefits of exercise.

The Science Behind Exercise and Mental Health

To better understand the relationship between mental health and exercise, we need to draw on neuroscience, physiology, and psychology.

When you engage in physical exercises like walking and running, your heart rate increases and circulation improves. This improved circulation delivers more oxygen and nutrients to your brain, especially the hippocampus (which is responsible for memory) and the prefrontal cortex (which is responsible for decision-making and focus).

As your body moves, the brain triggers the release of mood-enhancing chemicals like dopamine, serotonin, and norepinephrine. They help regulate mood, improve attention, and reduce anxiety.

This physical movement further enhances the release of brain-derived neurotrophic factor (BDNF), a growth factor that supports the development of new brain cells and strengthens the connections between them. This process is called neurogenesis (the birth of new neurons).

Exercises go further to release your happy and feel-good hormones, which boost your mood and self-esteem.

How Exercise Benefits Your Mental Health

Generally, exercising is one of the easiest ways to reduce the risk of mental health problems.

Let’s take a deeper look at how exercise affects our mental processes and reduces our risk of mental illnesses.

1.Enhances Cognitive Function and Brain Health

There is scientific evidence based on neuroimaging that demonstrates the efficacy of physical exercise on cognitive function.

Studies show that exercise affects cognitive abilities by affecting molecular events related to the management of energy metabolism and synaptic plasticity. This means that the improved circulation and secretion of chemicals in the brain enhance cognitive function and brain health.

The cognitive function of the brain involves memory, learning, attention, problem-solving, decision-making, and all other activities that your brain coordinates.

As a result of the consistent movement, you get better with memory, attention, processing speed, and executive function.

2.Boosts Mood and Reduces Depression

Exercise can be just as effective as antidepressants in managing mild to moderate depression and anxiety, and it comes without the side effects.

A study from 2019 revealed that if you run for just 15 minutes a day or take a one-hour walk, you might reduce your risk of major depression by 26%.

Furthermore, regular exercise helps regulate stress hormones like cortisol, reducing the harmful impact of chronic stress on the brain. Emotionally, this creates a greater sense of balance and resilience.

Sticking to a regular exercise routine can help prevent relapse of depression symptoms.

3.Alleviates Anxiety and Stress

According to the Anxiety and Depression Society of America, exercise triggers the release of endorphins, which are natural mood lifters that help reduce feelings of stress and anxiety. This neurochemical is a natural pain reliever and mood booster. When you are stressed or anxious, relieving it is as important as eliminating the cause, and both work together.

Exercise has a positive impact on mental health by relieving the symptoms of stress and anxiety to help you cope. Physical activities achieve this process by regulating the cortisol levels, which is the hormone associated with stress, through its governing effects on the hypothalamic-pituitary-adrenal (HPA) glands.

That said, it is important to see a mental health professional to discuss mental health impacts, as this will create a long-term solution.

4.Improves Memory and Learning Abilities

As earlier stated, exercising boosts the production of a protein called brain-derived neurotrophic factor (BDNF).

BDNF supports the growth and survival of brain cells. This, in turn, enhances the connections and helps improve memory and learning.

A meta-analytic review of randomised controlled trials found that aerobic exercise improves executive function, attention, and processing speed. The process behind it is the increased blood flow to the brain, transferring additional oxygen and nutrients, as well as the increase in new brain cells.

Thus, individuals participating in daily exercise activities will feel more mentally awake and active.

5.Increases Self-Esteem and Confidence

Research carried out in 2016 tested the indirect and direct link between physical activities and self-esteem.

The researchers tested this hypothesis by introducing body mass index, perceived physical fitness and body image to 264 adult males. The conclusion was that regular physical exercise should be promoted, particularly among adults reporting low self-esteem.

When you engage in physical activity, it not only improves your body image but also enhances your perception of how fit you are. Plus, many participants experienced weight loss, which helped them gain confidence and improve overall self-esteem.

When someone has a positive body image, they tend to feel less depressed, have higher self-esteem, and engage in healthier behaviours.

6.Promotes Better Sleep Quality

A systematic review of 23 studies revealed the following:

• Mind-body exercises, such as tai chi and yoga, had a more significant effect on sleep than other types.
• Moderate-intensity physical activity is more effective than vigorous exercise in enhancing sleep quality for young and old individuals.
• Exercising for more than 90 minutes was linked to poor sleep. On the other hand, a 10-minute light exercise in the morning helped men sleep longer and women sleep better.
• Consistent and daily exercise had a more positive effect on sleep duration and quality than inconsistent exercise.
• Physical and mind-body exercise significantly improved sleep disturbances and insomnia in adults.

In summary, a longitudinal study examining sleep quality and physical activity in older adults found that higher initial sleep quality was also linked to increased subsequent physical activity.

7.Fosters Emotional Resilience and Coping Skills

Exercise helps people build resilience against everyday stress.

This study highlights that staying physically fit, particularly when it comes to building muscular strength, does more than just boost our physical health. It also helps us feel more capable and resilient when facing daily stressors.

This research underscores how exercise can be a powerful tool for improving our mental health, enhancing our ability to cope with challenges, and supporting our overall emotional well-being.

8.Stimulates Creativity and Problem-Solving

Engaging in physical movement every day can boost our creativity.

Researchers monitored people’s movements with accelerometers over five days and then evaluated their creative performance. The results showed that those who moved around more often were not only more fluent in their ideas but also came up with more original ideas.

This suggests that staying active enhances creativity more directly, perhaps by improving how our brains function and connecting different areas of our minds rather than just making us feel good. It’s a reminder of how important it is to stay active if we want to think outside the box.

9.Supports Social Connections and Reduces Loneliness

Negative thoughts and loneliness go hand in hand, but exercising with others, whether it’s lifting weights at the gym or joining a virtual fitness class can create a connection and help brighten our mood.

A study published in 2024 found that group workouts, with supportive elements like leaderboards and shout-outs, not only uplift spirits but also boost performance.

We are naturally social creatures, and isolation can increase stress and low mood. In contrast, exercising with others provides the social support that we need and improves our health.

For instance, a 2021 study showed that people in a group running program in the UK had more fun, ran faster, and felt more energised compared to running alone.

10.Delays Cognitive Decline and Enhances Longevity

As we age, it’s natural to experience some cognitive decline and a higher risk of conditions like dementia and memory loss. However, regular exercise offers a powerful way to slow down brain aging and keep the mind sharp.

Aerobic exercises not only increase the volume of the hippocampus but also promote neurogenesis, leading to the creation of new brain cells. This means that there’s less shrinkage in the hippocampus and improvement of blood flow to areas responsible for thinking, leading to better cognitive health overall.

Beyond boosting cognitive function, physical activity can also lift mood, reduce symptoms of depression, improve sleep quality, and enhance overall well-being.

What makes this connection even more fascinating is that exercise activates specific biological pathways that support brain health at every stage of life, making it one of the most effective strategies for promoting healthy cognitive aging.

The World Health Organisation recommends that older adults stay active by including both aerobic exercise and strength training in their routines.

11.Enhances Focus and Concentration

Aerobic activities such as brisk walking, cycling, or swimming increase blood flow to the brain, supplying it with more oxygen and nutrients. This helps the mind feel more alert and engaged.

Exercise also triggers the release of brain chemicals like dopamine and endorphins, which play key roles in attention, motivation, and mood regulation.

Over time, regular physical activity strengthens areas of the brain responsible for decision-making, memory, and mental clarity. It also helps reduce stress and anxiety, clearing away distractions and making it easier to stay focused.

Whether you’re studying, working, or just trying to stay mentally sharp, regular movement is a natural and effective way to boost your brainpower.

How to Maximise the Mental Health Benefits of Exercise

Maximising the mental health benefits of exercise is not just about how much exercise you do. It’s about how, why and when you do it. It is not enough to just know that exercise is good for your mental health. It is equally important to put that knowledge into action and make the most of those benefits.

Here’s how to do that:

• Be consistent with your exercise routine: When it comes to exercising, frequency is more important than intensity. Aim for 3-5 days a week. Even 30 minutes of walking or dancing can boost your mood and improve your sleep pattern.
• Choose aerobic and moderate intensity exercises like walking, running, and skipping. These activities improve blood flow to the brain and stimulate feel-good hormones, and are effective for reducing symptoms of depression and anxiety.
• Exercise in the morning or early afternoon to avoid sleep issues. Nighttime workouts often disrupt sleep, which is essential for mental health.
• Engage in social interaction when you can by exercising with friends or in an exercise class. This helps to deal with loneliness and increase motivation.
• Combine exercise with other healthy habits like eating healthy, hydration and stress management.
• Remember to see a mental health professional if you think your mental health is at risk.

Even with a busy schedule filled with work and household chores, finding time for movement can make a big difference in your overall quality of life. Incorporating exercise into your daily routine doesn’t have to be overwhelming.

Starting with simple moderate intensity activities like brisk walking, short home workouts, or dancing while cleaning can gradually increase your fitness level. Over time, these consistent efforts not only boost physical health but also help improve mental and physiological health also!

In conclusion, you need to show up for your mental well-being by exercising regularly. You don’t need to wait for a mental health concern to develop, in order to start exercising. Many mental health conditions can be prevented by having better mental health habits rather than taking medications.

Taking care of your mental well-being through exercise is a powerful step, but recovery and resilience also depend on quality rest. To support your brain and body in fully recharging, consider complementing your routine with magnesium supplementation.
