Physical activity can help reduce the risk of depression by up to 25%. Even light exercise, like walking for less than 150 minutes per week, lowers depression risk. Research involving over 191,000 participants shows that meeting physical activity guidelines could prevent 11.5% of depression cases. Activities such as walking, yoga, and strength training are particularly helpful, with more intense exercises offering stronger effects.
Key takeaways:
- Adults achieving 4.4 mMET-h/week reduce depression risk by 18%.
- Walking 7,500 steps daily cuts depression symptoms by 42%.
- Combining exercise with other treatments improves outcomes.
Physical activity benefits all age groups and genders, though extremely high exercise levels may increase mild depression risk in older adults. Start with small, manageable steps like 10-minute daily walks or short strength workouts to improve mental health. If pain or mobility issues make exercise difficult, chiropractic care can help address physical barriers and support an active lifestyle.

Research Results: Physical Activity’s Effect on Depression Risk
A comprehensive review and meta-analysis of 15 studies, involving 191,130 participants over a span of 2,110,588 person-years, highlights a protective link between physical activity and depression. The findings reveal an inverse curvilinear relationship – essentially, as physical activity levels rise, the risk of depression falls [4]. Even engaging in light activity can help reduce depression risk, offering valuable insights into how exercise type and intensity further shape these outcomes.
Activity Levels and Depression Reduction
The research pinpointed specific activity benchmarks that lower depression risk. Adults achieving 4.4 mMET-h/wk experienced an 18% reduction in depression risk, while those reaching 8.8 mMET-h/wk saw a 25% reduction [4]. On a broader scale, the data suggests that if less active adults met current physical activity guidelines, 11.5% of depression cases could potentially be avoided [4].
Different Exercise Types
The study also explored how various types of exercise impact depression risk. Activities like walking or jogging, yoga, and strength training emerged as particularly effective [1]. A meta-analysis quantified these effects, reporting moderate reductions in depression with effect sizes of –0.62 for walking/jogging, –0.55 for yoga, –0.49 for strength training, –0.43 for mixed aerobic exercises, and –0.42 for tai chi or qigong when compared to active controls [1].
"Exercise is an effective treatment for depression, with walking or jogging, yoga, and strength training more effective than other exercises, particularly when intense." – Michael Noetel, senior lecturer [1]
Even light activity offers benefits, though vigorous exercise tends to have stronger effects. Strength training and yoga stood out as the most sustainable options, likely due to higher acceptance and adherence rates. The study also noted that combining exercise with other treatments can enhance its effectiveness [1].
Results by Age and Gender
The benefits of physical activity extend across age groups and genders, with some notable differences. For example, physical activity effectively alleviates symptoms in mild to moderate depression, with a particularly strong impact on mildly depressed women [5].
Interestingly, extremely high activity levels may have a downside. Among Chinese adults aged 45 and older, those in the highest activity category faced a 37% higher risk of new-onset depression, primarily mild depression. This risk became significant beyond 4,536 MET-minutes per week [6].
Gender also played a role in how exercise types were received. Women appeared to benefit more from strength training and cycling, while men saw better results with yoga, tai chi, and aerobic exercise combined with psychotherapy [1]. Age further influenced outcomes: yoga and aerobic exercise were particularly helpful for older adults when paired with psychotherapy, while strength training proved more effective for younger individuals [1].
For adolescents, higher physical activity levels were linked to a 3% reduction in depression risk, with no major differences between boys and girls [7]. Overall, the evidence underscores the value of physical activity as a powerful tool for reducing depression risk across various groups, regardless of baseline mental health or other health conditions [1].
Daily Exercise Tips: Adding Physical Activity to Your Routine
Incorporating physical activity into your daily life doesn’t have to mean a complete overhaul of your schedule. Studies show that even small increases in movement can help reduce the risk of depression, proving that exercise is a powerful tool for mental health.
Daily Step Targets
Walking is one of the easiest and most effective ways to improve your mental well-being. Research indicates that taking at least 5,000 steps a day is associated with fewer symptoms of depression [8]. If you’re ready to take it up a notch, walking 7,500 steps or more daily can lead to a 42% reduction in depression symptoms [9]. Even better, for every additional 1,000 steps you take each day, your risk of developing depression decreases by 9% [9].
"Given [the new] study’s findings, I would encourage my clients – particularly those with mood disorders or looking to improve their mental well-being – to aim for a minimum of 5,000 steps a day as a starting point." – Supatra Tovar, PsyD [8]
Start with a goal of 5,000 steps and gradually increase by 500 steps as you feel ready. Adding more steps to your day can be as simple as taking the stairs instead of the elevator, walking after meals, or parking farther from store entrances. Many smartphones come with built-in step trackers, or you can use a pedometer to monitor your progress.
Starter Exercise Programs
Tracking steps is a great start, but adding short, structured workouts can make your routine even more effective. Mini-workouts lasting 5–15 minutes, spread throughout the day, can be just as impactful as longer sessions [10]. This approach works well for busy schedules and helps avoid the mindset of “all or nothing.”
The UC Davis Health Office of Wellness Education suggests breaking the American Heart Association’s weekly goal of 150 minutes of moderate-intensity exercise into smaller, manageable chunks. For example, you could do desk push-ups while waiting for your computer to boot up or chair squats during phone calls [10].
Short sessions – like three 10-minute walks – can provide the same benefits as a single 30-minute workout [11]. Even five minutes of daily exercise can lower blood pressure and reduce stress [11]. You can incorporate movement into your routine by doing squats while brushing your teeth, stretching while watching TV, or squeezing in quick ab exercises during commercial breaks.
"You can be really creative. People ask me what’s the best exercise? I tell people the best exercise is the one you like the most, because that’s the one that you’ll stick to and do the most often." – Brandee Waite, MD, Director of UC Davis Health Sports Medicine [10]
To stay consistent, schedule your workouts, set reminders for movement breaks, and track your progress using a journal or fitness app. Small victories add up and help keep you motivated.

Public Health Impact: Exercise for Mental Wellness
Encouraging physical activity has a profound effect on public health, particularly in reducing the risk of depression across the United States.
Exercise as Depression Prevention
Every year, about 9.5% of adults in the U.S. experience depression, and nearly 17% will face a major depressive episode at some point in their lives [14]. The financial toll is immense – depression is the leading cause of disability in the U.S., costing over $40 billion annually in lost productivity and medical expenses [14].
Exercise offers a powerful way to combat this issue. It boosts brain health, enhances cognitive function, improves sleep quality, and lowers the risk of anxiety and depression for individuals of all ages [12]. For adults over 40, increasing moderate-to-vigorous physical activity could save up to 110,000 lives annually [18]. Additionally, regular exercise reduces the risk of chronic diseases by 20–30% [13] and helps stabilize mood.
"Although not a cure-all, increasing physical activity directly contributes to improved mental health and better overall health and well-being." [12]
In some cases, exercise can be as effective as medication in alleviating depression symptoms [14]. It complements traditional treatments and may work by boosting levels of brain-derived neurotrophic factor (BDNF), a protein critical for learning and cell growth [19].
However, physical inactivity remains a global challenge. Around 1.8 billion adults worldwide are not active enough [17]. In the U.S., many young adults spend over nine hours a day sitting [20], and insufficient physical activity increases the risk of death by 20–30% [17]. This sedentary behavior also raises the likelihood of anxiety and depression [20][21], but reducing sitting time by just 60 minutes a day can help mitigate these risks [20].
To address this, community-level action is vital. Promoting regular exercise through public health initiatives can significantly improve mental wellness [16]. This includes creating safer walking and cycling paths, increasing physical activity programs in schools and workplaces, and expanding access to community sports and recreational spaces [17]. On a global scale, targets have been set to cut physical inactivity by 10% by 2025 and 15% by 2030 [17]. Without action, the estimated global cost of physical inactivity to healthcare systems between 2020 and 2030 could reach $300 billion, or about $27 billion annually [17].
"Our study looked at physical activity as a way to prevent depression. But the good news from other research is that even if you are already feeling depressed, physical activity helps too…. I would say: Start somewhere – remember that something is better than nothing at all." – Karmel Choi, Postdoctoral Fellow at Harvard T.H. Chan School of Public Health [15]
These benefits highlight the importance of addressing physical barriers to activity, which is where chiropractic care can make a difference.
Chiropractic Care for Complete Wellness
While community programs encourage exercise, overcoming individual physical challenges is equally important. Pain or mobility issues often prevent people from staying active, which can increase the risk of depression. This is where personalized healthcare, including chiropractic care, becomes essential.
For example, Portland Chiropractic Group in Oklahoma City, Oklahoma, focuses on helping individuals overcome these barriers. Pain or restricted movement can lead to sedentary habits, which in turn contribute to mental health struggles. Dr. Brett Weaver and his team use evidence-based methods, such as chiropractic adjustments, to improve spinal alignment and joint mobility. These treatments make it easier and safer for patients to engage in regular physical activity.
The clinic also offers specialized services like the Graston technique and dry needling to address soft tissue restrictions and muscle tension caused by prolonged sitting or old injuries [20]. These therapies help restore mobility, allowing patients to build the foundation needed for an active lifestyle.
Functional training is another key offering, helping patients strengthen their bodies for everyday tasks and work toward the recommended 150 minutes of moderate-intensity aerobic activity each week [12]. The clinic’s patient-centered approach recognizes that everyone’s journey to an active lifestyle is different. Some may begin with basic mobility exercises, while others might need ongoing support to maintain consistent exercise habits.
For those dealing with chronic pain, tools like shockwave therapy can be a game-changer, easing discomfort and enabling movement. Structured care packages further ensure that patients receive consistent support, making it easier to stick with rehabilitation and embrace an active lifestyle.
Summary: Main Points and Action Steps
Research shows that physical activity can significantly lower the risk of depression – even if you don’t hit the full recommended exercise guidelines. Adults who complete just half the suggested amount of exercise reduce their depression risk by 18%, while those meeting the full recommendations see a 25% reduction. If inactive individuals became more active, around 11.5% of depression cases could potentially be avoided [3]. Activities like walking, jogging, yoga, and strength training – especially when done with some intensity – are particularly effective. The benefits apply regardless of pre-existing health conditions or current levels of depression [2].
Even small amounts of exercise, as little as five to 15 minutes daily, can add up to meaningful mental health improvements [22] [23].
"Practical wisdom suggests that doing something is better than doing nothing in terms of physical activity." – David Muzina, MD, Psychiatrist [22]
Start small and work your way up. A realistic starting point could be a 10-minute walk each day. Over time, aim to build up to 30 minutes of activity, five days a week. Mix in cardio, strength training, and yoga, and treat these sessions like non-negotiable appointments on your calendar [22] [23].
If pain or mobility issues make exercise difficult, consider reaching out to Portland Chiropractic Group. Dr. Brett Weaver and his team offer chiropractic adjustments, the Graston technique, and dry needling to help address barriers to movement, setting the stage for a consistent exercise routine.
Exercise doesn’t just boost physical health – it also increases levels of endorphins, serotonin, and dopamine, which can improve sleep and self-esteem. Pairing regular exercise with chiropractic care can further reduce stress and muscle tension, creating the perfect conditions for a healthier, more active lifestyle [23] [24] [25] [26].
Take the first step today. Whether it’s a brisk walk around your neighborhood or scheduling a consultation to address physical challenges, every effort you make will contribute to better mental health.
FAQs
How does physical activity help lower the risk of depression, and what processes in the body are involved?
Physical activity plays a key role in lowering the risk of depression by sparking a variety of positive changes in the body. For starters, it boosts the release of endorphins, the body’s natural mood enhancers. It also promotes brain health through neuroregeneration, a process that helps grow and repair brain cells. On top of that, regular exercise helps keep inflammation and oxidative stress – both linked to depression – in check.
Exercise also impacts crucial brain chemicals, including neurotransmitters like serotonin and dopamine, which are closely tied to mood regulation. It encourages the release of proteins such as neurotrophins, which are essential for maintaining brain health. Together, these effects help build a strong defense against depression and support overall mental well-being.
What kinds of physical activities are most effective at reducing the risk of depression?
Research indicates that aerobic exercises – like jogging, cycling, or swimming – and resistance training such as weightlifting are particularly effective at reducing the risk of depression. These types of workouts tend to have the most noticeable impact, especially when practiced regularly.
Activities like yoga and other mind-body exercises also offer meaningful mental health benefits by helping to ease stress and encourage relaxation. The most important factor is choosing an activity you genuinely enjoy and can commit to, as staying active is crucial for both your mental and physical health.
Can high levels of physical activity pose risks for older adults, and how can these risks be safely managed?
While staying active brings plenty of health perks, older adults need to be cautious, as overdoing it or diving into exercise without the right approach can lead to problems like joint strain, muscle injuries, fractures, or overuse issues. These risks often show up when trying out new routines or tackling high-impact exercises without adequate preparation.
To exercise safely, it’s best to take things slow. Start by gradually increasing intensity and adding in balance and flexibility exercises to help with stability and mobility. Opt for low-impact activities like walking, swimming, or yoga, which are gentler on the joints. Before starting any new fitness program, especially if there are pre-existing health concerns, it’s wise to check in with a healthcare provider. For added safety and to ensure proper form, consider supervised or guided workouts.
