Does this sound like the set of challenges you might be facing?

  • After a rough night I go to bed early, nap in the afternoon, sleep in on the weekend to make up for it
  • I’ve thrown everything at my sleep
  • On the days I barely move or do anything mentally demanding, I’d expect to crash hard at night
  • I get into bed an hour or two early to give myself the best shot at sleep, and instead I just lie there weirdly wide awake
  • It’s not really my thoughts keeping me up, it’s my body

Practices that may help

  1. The Two-Process Model of Sleep
    Alexander Borbély’s two-process model describes sleep as the interaction of two independent systems: Process S (homeostatic sleep pressure, which builds throughout waking hours like a battery draining) and Process C (the circadian clock, which gates sleep propensity in a 24-hour rhythm). Good sleep requires both processes to align — sleep pressure high and the clock in its nighttime phase simultaneously. The model is well established in sleep science.
  2. Build homeostatic sleep pressure by staying awake
    Resist napping late or sleeping in when you want to fix your sleep — consistent waking builds the pressure that makes sleep arrive.

  3. Use the two-process model to diagnose your specific sleep problem
    Identify whether your sleep issue is a Process S problem, a Process C problem, or both — because the fixes are different.

  4. Use vigorous daytime activity to build a clean Process S curve
    Physical and mental activity during the day steepen the sleep pressure curve, making evening sleepiness arrive on time.

  5. Sleep Pressure and Adenosine: The Science of Feeling Sleepy
    Sleep pressure is the physiological drive to sleep that builds continuously during waking hours through the accumulation of adenosine — a metabolic byproduct of neural activity. The longer you are awake, the more adenosine accumulates; the stronger the drive to sleep. Caffeine blocks adenosine receptors temporarily, masking but not eliminating this drive. Understanding this process is the key to managing fatigue, naps, and caffeine intelligently.
  6. Align your sleep window with the circadian gate
    Go to bed when both systems are aligned: sleep pressure is high AND the clock is in its sleep phase.

  7. Progressive muscle relaxation to lower physical arousal
    Systematically tense and release muscle groups from feet to head to lower the physiological arousal that blocks sleep onset.

  8. Treat sleep as the primary allostatic reset
    Consistent, sufficient sleep is the single highest-leverage intervention for reducing accumulated stress load.

  9. Fix your wake time (not bedtime) first
    A consistent wake time anchors your circadian rhythm and lets adenosine build to adequate pressure by bedtime — fixing sleep far more reliably than a fixed bedtime.

  10. Build a no-work buffer in the final 60 minutes
    Closing work tasks at least 60 minutes before bed allows the sympathetic nervous system to downregulate before sleep is attempted.
