Sleep

Best Approach

The bedroom should be a cave — dark, cool, quiet, and clean air. Most people optimize the mattress and ignore the room. Total blackout is worth more than a $3,000 mattress upgrade. Layer your environment: blackout first, then temperature control, then air quality, then sound masking. Each layer compounds.

What to Know

DarknessTotal blackout. Zero light. Motorized blackout shades or quality manual blackouts.
TemperatureRoom temp 65–68°F. Separate from mattress cooling. Dedicated mini-split or smart thermostat.
Humidity40–60% relative humidity. Too dry wrecks airways. Humidifier in winter, dehumidifier in summer.
Air QualityHEPA purifier in bedroom. CO2 should stay under 800ppm — crack a window or run an ERV.
SoundConsistent low-frequency masking (brown noise) or acoustic treatment. Eliminate intermittent noise.
EMFWiFi router out of bedroom. Phone on airplane mode or across the room. Controversial but low-cost.
Light at NightRed/amber only after 8pm. No overhead lights. Smart bulbs with circadian schedules.
Morning LightDawn simulation (sunrise alarm) or automated shades that open gradually. Huge for wake quality.
