Your Body's Built-In Stress Manager
Meet the vagus nerve, the longest cranial nerve in your body. It acts as a superhighway of information, connecting your brain to many of your most important organs, including your heart, lungs, and digestive tract. It's a key player in your parasympathetic
nervous system, which is responsible for your body's “rest and digest” functions. When the vagus nerve is stimulated, it sends a signal to your brain and body that you are safe, helping to counteract the “fight or flight” response that defines moments of high stress. This activation can help slow your heart rate, lower blood pressure, and promote a sense of calm.
The Power of Your Breath
One of the most direct and powerful ways to influence your vagus nerve is through your breath. When you are stressed, your breathing often becomes shallow and rapid, centred in your chest. This pattern signals danger to your nervous system. By consciously shifting to slower, deeper breathing, you mechanically stimulate the vagus nerve, which passes through your diaphragm. This intentional breathing tells your body to switch from a state of high alert to one of relaxation. A longer exhale, in particular, is effective at activating this calming response.
Technique 1: Diaphragmatic (Belly) Breathing
This is the foundation of all calming breathwork. Most of us have become shallow “chest breathers,” but re-engaging the diaphragm is key to stress reduction. This can be done discreetly right at your desk. Sit up straight with your feet flat on the floor. Place one hand on your belly, just above your navel. As you inhale slowly through your nose, focus on letting your belly expand and push your hand out. Your chest should remain relatively still. Then, exhale slowly through your mouth, feeling your belly fall as the air is released. Aim for an exhale that is slightly longer than your inhale. Repeat this for several cycles, focusing on the gentle rise and fall of your abdomen.
Technique 2: Box Breathing
Popularised by everyone from athletes to military personnel, box breathing is incredibly effective for restoring focus and calm under pressure. Its simple, rhythmic nature makes it easy to remember and practice anywhere. The technique follows the four sides of a box: Inhale slowly through your nose for a count of four. Gently hold your breath for a count of four. Exhale slowly through your mouth for a count of four. Hold the breath out for a count of four before beginning the next cycle. You can repeat this for a few minutes before a meeting or whenever you feel overwhelmed. The structure helps anchor your mind and regulate your nervous system.
Technique 3: The Physiological Sigh
When you need a rapid reset, the physiological sigh is perhaps the fastest way to offload stress. Popularised by neuroscientist Andrew Huberman, this technique is something our bodies do spontaneously to release tension. To do it intentionally, take a deep inhale through your nose. Then, before you exhale, take another short, sharp inhale to fully inflate your lungs. Finally, release all the air with a long, slow exhale through your mouth. Research suggests just one or two rounds of this can have a noticeable and immediate calming effect by helping to offload excess carbon dioxide and activate the parasympathetic nervous system.
Making It a Habit at Work
The key to leveraging these techniques is to use them before stress becomes overwhelming. Try scheduling “breathing breaks” in your calendar. Practice for a minute or two before logging into a challenging meeting or after finishing a difficult task. You can do box breathing while reading emails or practice diaphragmatic breathing during a short walk. The more you integrate these small moments of intentional breath into your workday, the more resilient your nervous system will become. You are not just managing stress; you are training your body to return to a state of balance more efficiently.
