A new method for measuring the body’s relaxation response, called Heart-Breath Coherence (HBC), achieves 91% accuracy in identifying stress states

Young adults with post-traumatic stress disorder (PTSD) symptoms show a significantly heightened breathing response when they briefly wake up from sleep. This finding, from a study at The University of Melbourne, suggests a hidden physiological link between PTSD and a key driver of obstructive sleep apnea (OSA), even when full-blown sleep apnea isn’t yet present….

The Science of Breath: How Mindful Breathing Programs Regulate Stress and Health A systematic review of controlled studies on Isha Yoga finds its integr…

One Week of Guided Slow Breathing Boosts Martial Arts Performance Forty high-level martial arts athletes, trained in disciplines like karate and taekwon…

A 2026 study from the University of Melbourne found that young adults with post-traumatic stress disorder (PTSD) symptoms have a significantly stronger breathing surge when briefly waking up from sleep. This “ventilatory response to arousal” was elevated even in individuals who did not yet have obstructive sleep apnea (OSA), suggesting a hidden physiological link between…

Beyond Oxygen: The Overlooked Role of Carbon Dioxide in Sleep Apnea Obstructive sleep apnea (OSA) is typically framed as a problem of oxygen starvation

Young adults with symptoms of post-traumatic stress disorder (PTSD) show a significantly stronger breathing surge when briefly waking up from sleep, a new study finds. This heightened “ventilatory response to arousal” may explain the known link between PTSD and obstructive sleep apnea (OSA), even in a young, otherwise healthy population without the condition. Key Takeaways…

A Breathing Pattern Reduced Insomnia Severity in Tinnitus Patients Patients with tinnitus often struggle with anxiety and poor sleep

**Elevated Arousal Breathing Response in Young Adults with PTSD Symptoms** A new study has found that while young adults with symptoms of post-traumatic stress disorder (PTSD) do not have a higher rate of obstructive sleep apnea (OSA), they do exhibit a heightened breathing response to brief awakenings during sleep. This “ventilatory response to arousal” may…

Individuals with post-traumatic stress disorder (PTSD) symptoms have a significantly stronger breathing surge upon waking from sleep, a physiological trait linked to the development of obstructive sleep apnea (OSA). A 2026 study led by researchers at the University of Melbourne found that this heightened “ventilatory response to arousal” was present even in young adults who…
