Long Exhale for parasympathetic nervous system activation Show Written by Mark Long Exhale is a slow controlled breathing technique with exhale longer than inhale and no breath-holding in between. We recommend this practice when your measurement implies low activity of your parasympathetic nervous system, which is responsible for rest. This means you’re under a lot of stress and need some relaxation to think properly and make decisions. How to do itYou should breathe in and out slowly, gradually extending your exhale until it gets twice as long as your inhale. That’s the pace we set in our audio. We provide a 10-minute audio, but if you’re pressed for time, it’s ok to cut the practice short — even a 2-minute session will lower your stress. However, the general rule is as follows: higher stress requires longer breathing sessions. For beginners, we recommend starting with not very deep breaths — otherwise, you may feel faint due to hyperventilation. Deepen your breathing, as you feel comfortable. If you’re not familiar with breathing practices, you may get bored or find it hard to concentrate. If so, don’t stop the practice: with the audio playing on the background, let your breathing follow the sound while you surf the news or flip through Instagram. How it worksSlow controlled breathing with long exhales moves the nervous system away from the fight-or-flight mode and towards rest-and-digest. It happens due to respiratory vagus nerve stimulation: during inhalation, the sympathetic nervous system facilitates a brief acceleration of heart rate; during exhalation, the vagus nerve secretes a transmitter substance (acetylcholine, or ACh) causing deceleration within beat-to-beat intervals via the parasympathetic nervous system. The Long Exhale technique improves heart rate variability (HRV) metrics and positively affects decision-making. Proven effectThe effect of the Long Exhale technique is described in the following scientific publications:
Interestingly, longer exhalations are called “an easy way to hack your vagus nerve” by Christopher Bergland, a world-class endurance athlete, with a Guinness World Record for running on a treadmill, and three-time champion of the Triple Ironman.

What is the fastest way to activate the parasympathetic nervous system?There are many ways to practice using your parasympathetic nervous system. These include mild exercise, meditation, yoga, deep breathing from your diaphragm, even nature walks. For some people, traditional meditation isn't their thing. It's about finding your body's way of meditating, what helps you to decompress.
Does holding your breath activate parasympathetic nervous system?Focusing on diaphragmatic breathing enables us to down regulate the sympathetic nervous system, which then causes the parasympathetic nervous system to become dominant. Shallow breathing, breath holding and hyper-ventilating triggers the sympathetic nervous system, in a "fight or flight" response.
How deep breathing activates the parasympathetic nervous system?Breathing deeply, with a slow and steady inhalation to exhalation ratio, signals our parasympathetic nervous system to calm the body down. Long, deep breaths can also manage our stress responses to help decrease anxiety, fear, racing thoughts, a rapid heartbeat and shallow chest breathing.
What stimulates the parasympathetic system?Stimulating the vagus nerve stimulates the parasympathetic nervous system, which in turns reduces our neurophysiological experience of stress. It reduces our heart rate and blood pressure.
