The Role of Exercise in Reducing Anxiety Symptoms
Anxiety affects more than 40 million adults in the U.S. each year, making it the most common mental health condition today. But anxiety isn’t just a mental experience—it’s a full-body one. Racing thoughts, tight muscles, shortness of breath, and feeling on edge are all signs that your nervous system is stuck in high alert. Over time, chronic stress and anxiety wear down your body and mind, leading to fatigue, sleep disruption, and emotional overwhelm.
Understanding how anxiety affects the nervous system—and how gentle, intentional movement can help—offers a powerful path to relief that’s grounded in both science and compassion.
How Anxiety Impacts the Nervous System
When you feel anxious, your body activates the sympathetic nervous system—also known as the fight-or-flight response. This ancient survival system prepares you to react to danger by increasing heart rate, tightening muscles, and flooding your body with stress hormones like cortisol and adrenaline.
The problem? In modern life, stressors like deadlines, trauma reminders, or emotional triggers can keep your sympathetic system activated far too often. Over time, this dysregulation can lead to chronic tension, insomnia, irritability, and panic attacks.
The antidote lies in activating the parasympathetic nervous system, also known as the “rest and digest” response. This system helps your body return to a state of calm, restoring balance and making you feel grounded and safe again.
5 Ways Exercise Reduces Anxiety
1. Lowers Cortisol and Boosts Mood
Exercise reduces cortisol levels and increases endorphins—your body’s natural mood-lifting chemicals. Physical activity also raises dopamine and serotonin, which are often depleted in those struggling with anxiety and depression.

2. Calms the Nervous System
Gentle movement shifts your body out of fight-or-flight mode and into a calmer, more regulated state. Rhythmic activities like walking or stretching activate sensory awareness, helping your brain feel safer.
3. Improves Sleep and Mental Clarity
Anxiety often disrupts sleep, which worsens mood and cognitive function. Exercise supports deeper, more restful sleep—which is essential for anxiety recovery.
4. Boosts Brain-Derived Neurotrophic Factor (BDNF)
BDNF is a protein that supports brain plasticity, memory, and resilience. Regular movement increases BDNF levels, helping your brain adapt more effectively to stress and reducing anxiety symptoms.
5. Builds Confidence and Self-Efficacy
Feeling strong and capable in your body can significantly improve self-esteem. Even low-impact exercise fosters a sense of control and agency—key ingredients in reducing anxiety.
Anxiety-Reducing Exercises to Try
Walking, Jogging, or Biking
Cardio exercises increase oxygen flow and help discharge excess energy. Just 20–30 minutes, 3–5 times a week, can significantly reduce symptoms of anxiety.
See the Journal of Psychiatric Research
Strength Training
Weightlifting or bodyweight resistance training lowers generalized anxiety, particularly in women and young adults. It builds physical and emotional resilience.
Yoga, Tai Chi, and Qigong
These mind-body practices integrate breath, awareness, and gentle movement—making them ideal for nervous system regulation.

Nature-Based Movement (“Green Exercise”)
Walking outdoors has added benefits: reduced cortisol, improved mood, and greater sensory grounding.

Why Trauma-Informed Movement Matters
Traditional fitness spaces can feel unsafe or inaccessible—especially for those with trauma histories. A trauma-informed approach to movement emphasizes:
Choice over compliance
Emotional safety over performance
Inclusive modifications
Grounding through breath and interoception
Trauma Center Trauma-Sensitive Yoga (TCTSY) and similar approaches help individuals reconnect to their bodies safely, without pressure or comparison. This kind of movement fosters a deep sense of agency, healing, and empowerment.
How to Choose the Right Movement for You
There’s no “best” form of exercise for anxiety relief—what matters is what feels safe and sustainable for your nervous system.
Ask yourself:
What types of movement feel accessible right now?
Do I feel more connected or more overwhelmed after moving?
What helps me feel present in my body?
Start with small steps: stretch in bed, sway to music, or walk around your block. Let curiosity—not comparison—guide you.
How to Start a Gentle Movement Practice
You don’t need high-intensity workouts to feel better. Here’s how to ease into a consistent practice:
Start small: even 5–10 minutes is enough
Choose joy: find what feels good or grounding
Use breathwork before and after movement
Allow for rest and modification
Let go of perfectionism: listen to your body’s cues
Trauma-aware movement prioritizes your felt sense of safety and agency over appearance, numbers, or performance.
Frequently Asked Questions
Can exercise make anxiety worse?
If done too intensely or without consideration for trauma history, yes—it can. That’s why a trauma-informed, body-aware approach matters. If your body feels unsafe or overwhelmed, slow down, and prioritize gentleness.
How soon will I notice results?
Many people feel a mood lift right away. For longer-term anxiety relief, consistency over 4–6 weeks tends to yield the most noticeable shifts in mood, sleep, and nervous system balance.
What’s the best time of day to exercise for anxiety?
Whatever time fits your schedule consistently! Some people find morning workouts help start their day with clarity, while others prefer movement in the evening to wind down. Keep in mind more intense exercise closer to bed could make it difficult to fall asleep.
