  • Sources:

    Physiological sighing, a technique extensively discussed by , involves taking a big, deep inhale through the nose, followed by a second, short inhale to fully inflate the lungs, and then a long exhale through the mouth. This practice can quickly induce a sense of calm and reduce stress.

    Here are some key insights on physiological sighing:

    1. Origins and Mechanisms:

      • Discovered in the 1930s by physiologists, the physiological sigh has been studied in detail by labs at UCLA and Stanford 1.
      • It helps clear carbon dioxide buildup in the body by fully expanding lung sacs (alveoli) and allowing for efficient exhalation of CO2, which rapidly reduces stress 2.
    2. Applications and Benefits:

      • Stress Reduction: Performing a physiological sigh is the fastest way to reduce stress and induce a state of calm, effective even when done just once or twice 3.
      • Sleep and Emotional Regulation: Helps with transitioning into sleep and can be beneficial after crying or during moments of acute stress 1.
      • Exercise Recovery: Incorporating physiological sighs between workout sets can accelerate heart rate recovery and overall workout recovery 4.
      • Daily Use: Utilizing cyclic sighing (repeated physiological sighs for five minutes a day) has been shown to lower stress levels, improve mood, and enhance overall well-being over the course of a 24-hour period 3.
    3. Practical Instructions:

      • Execution: Simply take a deep inhale through your nose, sneak in a quick second inhale, and then exhale fully through your mouth 5.
      • Frequency: Can be done multiple times a day as needed, particularly in stressful situations or to help relax.

    To sum up, the physiological sigh is a straightforward yet powerful tool to manage stress and improve emotional and physical well-being. It leverages basic respiratory mechanisms to bring about significant calming effects and can be easily integrated into daily routines.
