If you’ve ever felt like the weight of the world is on your shoulders, you’re not alone. Whether you’re dealing with chronic stress that sticks around or the occasional bad day that throws you off, exercise is one way to help clear your mind and reset.
But does exercise help reduce stress, or is that just another wellness myth? Let’s break it down and explore how moving your body—whether you’re running, lifting weights, or practicing yoga—can make a real difference.
Understanding Stress
Before we dive into how exercise can help, it’s important to understand what stress does to the body. Stress triggers a fight-or-flight response, releasing hormones like adrenaline and cortisol that help us react to danger. While that’s useful if you’re, say, running away from a bear, it’s not so great when you’re just trying to get through a hectic workday or cope with daily anxiety.
When stress goes unmanaged, it can lead to both mental stress and physical health issues, even in otherwise healthy adults. Long-term exposure to high levels of stress can contribute to heart disease, high blood pressure, and mental health disorders like anxiety and depression.
Some common indicators of stress may include:
Trouble sleeping
Increased anxiety or irritability
Fatigue
Headaches
Tense muscles
Difficulty concentrating
Acute Stress
Acute stress is the type of stress that hits you suddenly but doesn’t stick around for too long. It’s that surge of adrenaline when you’re preparing for a big moment—like giving a presentation, running late to an appointment, or dealing with a minor crisis at work.
In some ways, acute stress can be helpful. It’s your body’s way of gearing up for action, sharpening your focus, and giving you a quick burst of energy. Think of it like the body’s internal “alarm system” that helps you react to immediate challenges.
In small doses, acute stress can be motivating. For example, it might push you to meet a tight deadline or finish a project you’ve been putting off. In fact, short bursts of stress (like the pre-race jitters you feel at the start line before a big race) can help improve your performance by boosting alertness and concentration. But it’s all about balance. Too much acute stress over time, without proper recovery, can start to wear you down, leading to irritability, headaches, or trouble sleeping.
Chronic Stress
Chronic stress, on the other hand, is much more long-lasting. It’s not the quick surge of stress you feel before a big race; instead, it’s the stress that builds up over time and sticks with you. This type of stress is often tied to ongoing life pressures, like work-related burnout, financial struggles, relationship problems, or caring for a loved one. Chronic stress tends to simmer in the background, but its effects can be far-reaching.
The Impact of Chronic Stress on the Body
Mental stress can have a profound impact on the body, affecting everything from our mood and cognitive function to our cardiovascular health and immune system. When we experience stress, our body’s “fight or flight” response is triggered, releasing stress hormones like cortisol and adrenaline into the bloodstream. These hormones prepare our body to respond to the stressor by increasing our heart rate, blood pressure, and energy levels.
However, when we experience chronic stress, our body’s stress response system can become overactive, leading to a range of negative effects on our physical and mental health. Chronic stress has been linked to an increased risk of cardiovascular disease, anxiety disorders, and depression, as well as a range of other health problems.
The Science Behind Physical Activity and Stress Reduction
So, how does exercise reduce stress? When you move, your body releases endorphins—those feel-good chemicals that improve your mood. Physical exercise also reduces the level of cortisol, a hormone closely tied to stress. An article from Harvard Health explains, “Exercise reduces levels of the body's stress hormones, such as adrenaline and cortisol. It also stimulates the production of endorphins, chemicals in the brain that are the body's natural painkillers and mood elevators."
"The Runner's High"
Running, for example, can be a particularly effective way to break free from the grip of stress. It doesn’t just boost your physical health; it can clear your mind and help you find your rhythm—literally and mentally.
When you run, your body experiences a natural release of endorphins, which are chemicals in the brain that act as natural painkillers and mood elevators. This “runner’s high” is one of the most immediate benefits of running, making you feel lighter and more at ease, even after a tough day. But running offers more than just a temporary boost. Over time, regular running can improve your overall mental well-being by helping you build resilience against stress.
Mentally Disconnect
Mentally, physical exercise gives you a chance to disconnect from the day’s worries and focus on the simplicity of the task at hand. Running, in particular, encourages mindfulness as you naturally tune in to your breathing, your steps, and your surroundings. For many runners, this creates a meditative state that helps quiet the constant chatter in their minds.
Exercise is like a natural reset button for your brain. It helps to clear out the stress hormones and replace them with endorphins, which improve your mood and overall mental health.
Types of Exercise That Help Reduce Stress
The great news is that you don’t need to have elite levels of physical fitness or commit to one type of exercise to use physical activity for stress management. Different forms of movement can work to relieve stress, so it’s all about finding what works best for you.
Aerobic Exercise
Aerobic activities like running, cycling, and swimming increase your heart rate and help relieve stress. When you engage in these exercises, your brain releases endorphins, which provide a natural boost to your mood and help you feel more relaxed and focused. This chemical release can make a big difference in how you handle stress, both in the moment and throughout the day.
Strength Training
Lifting weights and engaging your major muscle groups can also be stress-relieving. Strength training shifts your focus onto what your body is capable of, which can help distract from the stresses of daily life. Plus, there’s something empowering about feeling stronger after each session.
Mind-Body Exercises
Yoga, tai chi, and even deep stretching can help calm your mind while working your body. These exercises focus on slow, deliberate movements paired with mindful breathing, making them ideal for reducing stress. Mind-body exercises bring together physical and mental disciplines to achieve peacefulness of body and mind, helping you relax and manage stress and anxiety.
Other Ways to Relieve Stress
While exercise is a fantastic way to combat stress, it’s not the only tool in your stress-relief toolkit. Just like running or strength training, other methods of reducing stress target both your mind and body, and sometimes it’s about mixing up your routine to find the perfect balance that works for you.
Here are a few other effective ways to manage stress and restore your sense of calm.
Mindfulness: Mindfulness is all about staying present in the moment. Instead of worrying about the past or future, mindfulness practices help you focus on what’s happening right now, which can greatly reduce stress.
Journaling: Journaling allows you to process emotions and organize your thoughts, especially when life feels chaotic or overwhelming. It’s a private space where you can reflect on what’s causing stress, recognize patterns, and figure out how to respond in a more effective way.
Spending Time Outdoors: Spending time outdoors, whether it’s taking a walk in the park, hiking in the woods, or just sitting in your backyard, can have a calming effect on both your mind and body.
Socializing and Building Connections: Social connections provide emotional support, offer new perspectives, and remind you that you’re not alone. Even something as small as a coffee chat or a phone call with a loved one can help you feel more grounded.
Mental Health Benefits of Exercise Beyond Stress Relief
The benefits of exercise extend beyond just stress relief. Moving your body regularly can positively affect your mental health in several other ways.
Manage Depression and Anxiety Disorders
One of the most well-researched mental health benefits of exercise is its ability to help manage symptoms of depression and anxiety. Exercise stimulates the production of neurotransmitters like serotonin and norepinephrine, which help improve mood and alleviate feelings of sadness.
Dr. Michael Craig Miller, a professor of psychiatry at Harvard Medical School, explains: “Exercise supports nerve cell growth in the hippocampus, improving nerve cell connections, which helps relieve depression."
By boosting mood-regulating chemicals in the brain, exercise provides a natural, side-effect-free method of tackling anxiety and depression. Even light exercise like walking or gentle stretching can make a big difference in reducing symptoms.
Improved Mood and Self-Esteem
One of the most immediate benefits of physical activity is its ability to boost your mood. You’ve likely experienced this yourself: after a good workout, your mind feels clearer, and you’re often in a better mood. But it’s not just about feeling good in the moment. Regular exercise can also enhance your long-term mood by building confidence and self-esteem. When you achieve small fitness goals, whether it’s running a mile, lifting a certain weight, or mastering a yoga pose, you reinforce a sense of accomplishment.
Better Sleep Quality
Another way exercise benefits mental health is by improving sleep quality. Stress, anxiety, and other mental health conditions often disrupt sleep, leading to insomnia and other negative physical symptoms. Exercise helps regulate your body’s circadian rhythm, the internal clock that manages your sleep-wake cycle. It also increases time spent in deep sleep, the most physically restorative stage of sleep, which helps your body and brain recover from the day’s activities.
According to the National Sleep Foundation, moderate aerobic exercise, such as a brisk walk or bike ride, increases the amount of slow-wave sleep (deep sleep) you get at night. Better sleep not only helps you feel more rested, but it also improves your emotional regulation and mental clarity during the day, making it easier to manage stress and anxiety.
Building Social Connections
Exercise also offers an excellent opportunity to build and strengthen social connections, which are crucial for mental health. Whether you join a running group, participate in fitness classes, or meet a friend for a workout, exercising with others fosters a sense of community and belonging. Social interactions are important for emotional well-being, as they provide support, encouragement, and a shared experience.
How to Know When Exercise Isn't Enough
While exercise is a powerful tool for managing stress, it’s important to know when it’s not enough. If you’re feeling overwhelmed, constantly anxious, or depressed despite regular physical activity, it might be time to talk to a mental health professional. Therapy or medication may be necessary to address deeper issues.
Dr. Miller reminds us, “For some people it works as well as antidepressants, although exercise alone isn't enough for someone with severe depression."
So, does exercise reduce stress? Absolutely. Whether you’re running through a forest trail, lifting weights, or rolling out your yoga mat, moving your body can help melt away stress, improve your mood, and give you a sense of control. The key is consistency—find the type of exercise you enjoy and stick with it. And remember, it’s okay to seek additional support when needed. After all, taking care of your mental health is just as important as taking care of your body.
