Short‑term stress is adaptive . It can enhance immune function, mental/physical performance and resilience, whereas chronic stress is maladaptive, suppressing systems and degrading performance. https://pmc.ncbi.nlm.nih.gov/articles/PMC5964013/

Breathing Modulates Network Activity in Frontal Brain Regions during Anxiety. Research reveals how anxiety alters breathing patterns and how these changes influence brain activity, offering new possibilities for targeted, breath-based interventions. https://pmc.ncbi.nlm.nih.gov/articles/PMC11714350/

The impact of mouth breathing on dento-facial development. Mouth breathing alters facial structure, disrupts saliva’s protective roles, increases dental and gum disease risk, affects jaw joint development, and may contribute to broader oral health problems. https://pmc.ncbi.nlm.nih.gov/articles/PMC9498581/#s5
