A simple double-inhale does the trick! Just like topping off your gas tank at the gas station, this will reset your Rest and Repair systems. Check it out
The breathing technique often referred to as the "physiological sigh"—has been studied by neuroscientists and psychologists, especially in recent years.
Notably, Dr. Andrew Huberman, a neuroscientist at Stanford University, has widely promoted this technique. The physiological sigh involves two quick inhales through the nose followed by a long exhale through the mouth.
Research published in 2023 in the journal Cell Reports Medicine by Spiegel et al., supported by Stanford researchers, compared various breathing techniques for stress and anxiety reduction.
Among these, cyclic sighing (two inhales, one prolonged exhale) showed superior results in lowering anxiety and improving mood when practiced for as little as 5 minutes daily.
The mechanism behind its effectiveness lies in how it affects the autonomic nervous system. The double inhale helps fully inflate the lungs, allowing more oxygen in and resetting the breathing rhythm, while the slow exhale activates the parasympathetic nervous system, promoting a sense of calm.
Unlike complex mindfulness or meditation techniques, this method requires no prior training and can be used anywhere, at any time, making it highly accessible.
Thus, the claim in the image is factually accurate, backed by modern neuroscience and peer-reviewed research. However, it’s worth noting that while effective for temporary relief, it should not replace long-term treatment or therapy in cases of chronic anxiety disorders.
