You probably know that moment when your heart starts racing before a meeting or a phone call. Most people reach for a walk or just hope it passes.
What you do with your next few breaths may matter more than you think.
Researchers at Stanford compared three short breathing exercises to mindfulness meditation. They found that five minutes a day of structured breathing eased anxiety and lifted mood more than meditation did.
The strongest effect came from a pattern called cyclic sighing. You take two inhales through the nose, then a long slow exhale through the mouth.

The trial, published in Cell Reports Medicine in January 2023, followed 108 healthy adults over four weeks.
Daily mood scores climbed and anxiety scores fell across all breathing groups. Cyclic sighing produced the biggest daily gain in positive feelings.
How slow breathing seems to calm the body
Slow breathing shifts the body out of its stress gear.
A 2018 systematic review in Frontiers in Human Neuroscience found that breathing at about six breaths a minute tilts the body toward the parasympathetic nervous system. That is the branch that controls rest and recovery.

The shift is carried by the vagus nerve, the long nerve that connects the brain to the heart and gut.
Heart rate slows, the gaps between beats become more flexible, and people report less arousal and less anxiety within minutes.
A separate 2017 trial in Frontiers in Psychology with 40 healthy adults found that eight weeks of diaphragmatic breathing lowered cortisol, the body's main stress hormone.
Five techniques in one sentence each
Cyclic sighing. Two short inhales through the nose, then a long slow exhale through the mouth, repeated for five minutes. In the Stanford trial it produced the biggest same-day mood lift and the largest drop in breathing rate.

Box breathing. Inhale for four counts, hold for four, exhale for four, hold for four. The Stanford trial also tested this pattern and saw anxiety ease, though the gain was smaller than with cyclic sighing.
4-7-8 breathing. A four-count inhale through the nose, a seven-count hold, and an eight-count exhale through the mouth. Popularized by physician Andrew Weil, with small trials in surgical patients linking the practice to lower anxiety scores.
Diaphragmatic belly breathing. Place a hand on the belly and breathe slowly through the nose so the belly rises on the inhale and falls on the exhale. The 2017 trial above tied an eight-week program to lower cortisol and better sustained attention.
Resonance breathing. Aim for about six breaths a minute, roughly five seconds in and five seconds out. The Frontiers review linked this pace to the clearest drops in anxiety and the biggest changes in heart rate variability.

Heart rate variability is the natural variation in time between each heartbeat. Higher values usually signal a calmer, more flexible nervous system.
Talk to your doctor
None of these techniques replaces care for anxiety that disrupts daily life. If your anxiety is persistent, severe or tied to panic attacks, talk to your doctor before relying on self-managed exercises.
For short, situational tension, the evidence points in a consistent direction. Five minutes of slow, exhale-heavy breathing is a portable, free tool that shifts your physiology within minutes.
A sensible way in is to pick one pattern, sit somewhere quiet, and practice it for five minutes a day for a week. See how your body responds, then adjust.
