Sleep and Biometric Monitoring

Sleep is the body's primary repair, regeneration, and immune recalibration window and is a foundational, chronically underemphasized modifiable factor in autoimmune disease. Self-rated sleep quality, energy level, and journaled impressions are at least as clinically meaningful as wearable metrics for autoimmune patients. Consumer wearables can detect sleep onset and waking through movement but cannot reliably quantify sleep stages; definitive measurement requires lab EEG. False sleep tracker feedback—not actual sleep architecture—determines participants' reported energy, cognitive function, and daytime somnolence, making tracker-induced anxiety itself a physiologically harmful intervention. A resting heart rate in the 80s warrants clinical attention for autoimmunity, cardiovascular health, and longevity; even the high 70s is suboptimal.
