Understanding insomnia: hyperarousal, CBT-I, paradoxical insomnia, and why different sleep problems require different treatments
At 13:22 · chapter starts 12:45
Before any medication enters the picture, Attia argues, the foundation must be behavioral. Circadian alignment requires regular wake times, morning sunlight, reduced evening light exposure, and a cool, dark bedroom. Homeostatic sleep pressure is cultivated by exercising intensely earlier in the day, avoiding naps, and not drinking coffee in the afternoon. For those with circadian-specific problems — owls who can't fall asleep, larks who can't stay asleep, or chronic social jet lag on weekends — circadian interventions take priority. For those with excessive daytime sleepiness, fragmented sleep, or heavy caffeine dependency, sleep pressure consolidation matters more. But sleep hygiene alone cannot fix hyperarousal. And before reaching for medications, Attia wants clinicians to rule out medical culprits. Restless leg syndrome affects 3% of adults globally but up to 13% by American self-report. Obstructive sleep apnea, driven by the obesity epidemic, likely affects about a third of US adults — 39% of males, 26% of females — with roughly 20% of cases severe. And mood or anxiety disorders, present in about a third of US adults in any given year, come with severe insomnia rates of 25–45% in sufferers, doubling when both are comorbid.
Hyperarousal: The Real Reason You Can't Sleep
Most insomnia that isn't caused by medical or environmental factors is driven by hyperarousal — elevated cortisol and high cortical activity holding the gas pedal down on wakefulness. CBT-I is the first-line treatment precisely because it targets this mechanism directly, retraining the nervous system rather than just making you more tired.
