In this episode, Mario and Max introduce physiological sighing (cyclic sighing) as an effective breathing technique for reducing acute stress. They explain the simple steps—two inhales through the nose followed by a long exhale through the mouth—and the physiological mechanism behind it. The technique helps regulate the autonomic nervous system and quickly brings you into a more relaxed state.
Cyclic sighing, also known as physiological sighing, is a breathing technique for moments of acute stress. It consists of two inhales through the nose followed by a slow, long exhale through the mouth. Mario demonstrates the technique and recommends repeating it about five times as needed. It is particularly useful in stressful situations, such as exams or challenges at work.
Max emphasizes that this breathing technique is not an artificial method. The body uses it spontaneously during periods of intense stress to regulate itself. A familiar example is children's sobbing after crying, which often involves this kind of double inhale. This natural tendency is one reason the technique is so effective.
Breathing techniques such as cyclic sighing are powerful tools because they offer one of the few ways to consciously influence the autonomic nervous system. You cannot simply decide to be calm, but you can choose to do a breathing exercise that has been shown to help you calm down. This allows you to actively regulate your own state of relaxation.
The effectiveness of cyclic sighing relies on two physiological processes. The additional inhale helps reinflate collapsed air sacs (alveoli) in the lungs, improving gas exchange. The long exhale that follows stimulates the baroreceptor reflex, which in turn activates the parasympathetic nervous system, bringing the body into a relaxed state.
Max personally prefers box breathing for his evening routine because the counting adds a meditative effect for him. Mario, on the other hand, values short afternoon breaks to regain focus, which can easily be combined with a breathing technique. They emphasize that the goal is to find the method that works for you and practice it regularly.
Acute stress cannot be switched off through willpower alone—but it can be regulated through breathing. Mario and Max explain the neurobiological effects of the physiological sigh, also known as cyclic sighing. They show how a double inhale reopens collapsed alveoli and how a slow exhale activates the vagus nerve.
Up to 45% of dementia cases may be preventable or delayable through modifiable risk factors. We cover blood pressure, blood sugar, sleep, exercise, hearing loss, diet, social connection and lifelong learning—and the steps you can take now.
Even one alcoholic drink can disrupt sleep, increase next-day stress and cause cellular damage. We explain why there is no risk-free level of alcohol consumption—and why drinking can still feel relaxing at first.
