A systematic review of 11 clinical trials on cold-water immersion concludes the practice may reduce stress and improve sleep

A study published in the *Journal of Clinical Sleep Medicine* found that young adults with post-traumatic stress disorder (PTSD) symptoms have a significantly stronger breathing response when they briefly wake up from sleep. This physiological trait is a known contributor to obstructive sleep apnea (OSA), suggesting a potential pathway linking PTSD to future sleep apnea…

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….

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…
