Sleep Assessment Methods

PSG is considered the gold standard for sleep assessment, but alternatives like cardiopulmonary coupling (CPC) offer unique insights into physiology and autonomic nervous system function. Both methods have their pros and cons, and it's essential to consult with a medical professional to determine the best approach for individual needs. Additionally, actigraphy devices, ranging from research-grade to consumer wearables, provide valuable data on sleep patterns, with many achieving impressive accuracy in tracking sleep stages.
