Box Breathing

Description:
Box breathing is a slow, rhythmic breathing technique involving equal-length inhales, holds, and exhales (e.g., 4–4–4–4). Originally used in military and performance psychology, it’s promoted as a simple, calming practice for regulating stress—one of the most common migraine triggers.

🧠 Biological Plausibility

Box breathing stimulates the parasympathetic nervous system and reduces sympathetic arousal, which can modulate stress responses that may trigger migraines. Though mechanistically plausible, its relevance to migraine pathophysiology is indirect.

🔬 Evidence: Weak

No trials have evaluated box breathing specifically for migraine. However, studies in other conditions show that slow-paced breathing can reduce perceived stress, anxiety, and physiological arousal, all of which are migraine-related factors.

🎯 Effect Size: Low

Any benefit is likely indirect and small. May reduce attack frequency in patients whose migraines are heavily influenced by stress, especially when used consistently.

⚠️ Risk: None

None. Very safe and easily self-administered.
