If you want the best breathing exercise to reduce stress, start with slow, comfortable breathing that you can repeat. Breath awareness is an easy first choice when counting or trying to take a deep breath feels like too much: notice your natural breath for a few minutes without trying to change it. A 2025 systematic review found that breathing exercises improved anxiety in 12 of 19 included adult studies and stress in nine studies, although large randomized trials are still limited.
Which breathing exercise is most effective for stress?
There is not one winning pattern for every person. The best first exercise is the one that helps you slow down without making you tense, lightheaded, or focused on getting the count perfect.
Slow breathing has the clearest fit for the question you are asking. In a 2023 randomized controlled trial of 64 adults with essential hypertension, researchers compared slow breathing, progressive muscle relaxation, both together, and no intervention over four weeks. They measured heart rate, breathing rate, blood pressure, and perceived stress. All three active groups improved over the no-intervention group on the measures tracked, including perceived stress. The combined group did not clearly beat slow breathing alone on blood pressure or heart rate, or muscle relaxation alone on perceived stress. Read the study record at the National Library of Medicine.
A 2025 systematic review of 19 adult studies also found that controlled breathing was associated with improvements in anxiety and stress outcomes. That is a useful reason to practice, not a reason to chase a complicated method. Start simple and give yourself a repeatable tool.
| Option | What you do | Best time to try it |
|---|---|---|
| Breath awareness | Notice where and how you are breathing without changing it. | When you feel wound up and want the gentlest starting point. |
| Slow breathing | Let your breaths become slower and comfortable. | When stress has made your breathing feel rushed or shallow. |
| Diaphragmatic breathing | Practice slow, deeper breathing that uses your diaphragm, the muscle below your lungs. | When you prefer a body-based practice and it feels comfortable. |
| Slow breathing plus muscle relaxation | Pair slower breaths with releasing tension in your muscles. | When stress shows up as a tight jaw, shoulders, hands, or legs. |
How do you start when anxiety makes breathing feel difficult?
Do not begin by forcing a huge breath. Begin by noticing the breath you already have. Illinois Extension describes breath awareness as watching the natural breath without judgment or trying to fit it into a pattern.
- Sit or lie down somewhere comfortable.
- Put one hand on your belly and one on your chest if that helps you notice movement.
- Notice where you feel the breath most: your nostrils, chest, ribs, or belly.
- Notice whether your inhale or exhale feels longer.
- Stay with that observation for a few minutes. Illinois Extension suggests gradually building toward five to 10 minutes.
This gives your attention one small job. If you would rather use a counted pattern, see this practical guide to box breathing and 4-7-8. Pick one method rather than switching between several in the same moment.
What does the research say about diaphragmatic breathing?
Diaphragmatic breathing is slow, deeper breathing that uses the diaphragm. A 2020 narrative review included 10 systematic reviews and 15 randomized controlled trials. It found that diaphragmatic breathing may help with stress and anxiety, while also noting that the quality of the available studies made its exact clinical role unclear. The review is available through PubMed.
For your everyday decision, that means it is a reasonable option to try if it feels natural. You do not need special equipment, an app, or the perfect breathing count to begin.
What can you do when stress will not let up?
Use breathing as one coping skill, not as the whole plan. Make it easier to repeat by connecting it to a regular moment in your day: before opening email, after getting in the car, or while getting ready for bed. Stress can also interfere with rest, so the next useful question may be how your evenings are going. Our guide to stress and sleep can help you notice that connection.
If stress is making daily life hard to manage, bring that specific change to a clinician or mental-health professional. You do not need to label the experience perfectly before asking for support.
Do drinks help with anxiety or stress?
A drink is not part of the breathing approaches covered here. Keep the immediate goal small: choose a place to sit, notice your breath, and give yourself a few quiet minutes. If you are considering a supplement for sleep or stress, this guide to magnesium and stress explains what to weigh before buying.
Before you make breathing practice another task
- Choose the least complicated method first: breath awareness or slow breathing.
- Practice at a predictable time, not only when stress is already at its highest.
- If counting makes you more tense, drop the count and return to noticing your natural breath.
- Pair breathing with another simple support, such as loosening muscle tension or protecting a calmer wind-down routine.
One practical next step: Set aside five minutes today, sit comfortably, and practice breath awareness without trying to fix your breathing.
