Look at your bedroom. Is it a sanctuary? Or is it an entertainment center/office/gym?
For millions of years, humans slept in caves. Dark. Cool. Quiet. Safe. Our biology still expects this. Modern bedrooms—filled with blinking LEDs, streetlights, and warm central heating—are anti-sleep environments. To sleep like an ancestor, you need to rebuild the cave.
The Science: Environmental Triggers
1. Darkness: Melatonin (the vampire hormone) only comes out in the dark. Even dim light suppresses it. 2. Temperature: The body needs to cool down to sleep. The ideal room temp is 65°F (18°C). 3. Silence: The brain processes sound even while asleep. Sudden noises trigger ‘cortisol arousals.’
The Strategy: Cave Construction
1. Blackout. Install heavy curtains or wear a high-quality eye mask. Tape over LEDs on TVs and chargers. 2. Chill. Set the thermostat to 65-68°F. Use breathable bedding. 3. Hush. Use white noise (fan or machine) to mask sudden sounds. It creates a ‘sound blanket.’ 4. Purge. Remove work desks, treadmills, and TVs. The bedroom is for sleep and sex only.
Why It Works (The Maas Method)
It removes the ‘threats’ to sleep. By controlling the inputs (light, heat, sound), you allow the nervous system to downregulate without distraction.
Common Mistakes to Avoid
Don’t overheat the room in winter. It feels cozy to get into a hot room, but it will wake you up at 3 AM. Warm the bed (hot water bottle), keep the room cool.
