The Sleep Architect | Your Brains Adjustment To Sleep When In Recovery
from Recovery Decoded · host Recovery Decoded
Why can't you sleep in early recovery? Your brain's natural brake pedal — a chemical called GABA — was replaced by your substance. Now it is being rebuilt.In this episode, we cover:• How your brain cleans itself during deep sleep (the glymphatic system)• What alcohol, opioids, and stimulants actually do to your sleep architecture — with research from a 27-study meta-analysis• Why your dreams are so vivid and intense right now (REM rebound — and why it is actually healing)• How one bad night of sleep raises cortisol 37% and slows your dopamine recovery• The "brake pedal" metaphor: why your heart races at 3am and when it stops• The Wind-Down Protocol: 4 steps for the last 90 minutes before bed• 4-7-8 breathing: the science of why it works (vagus nerve, parasympathetic activation) and exactly how to do itTonight's action: body scan (2-3 min) + 4-7-8 breathing (4 cycles). Under 5 minutes. Try it for 7 nights.REFERENCES:• Xie et al. (2013), Science — Glymphatic system discovery, University of Rochester• Pietilä et al.
