How to practice Eliminate electronics LEDs
Cover or unplug electronics emitting visible light; use opaque tape or reposition devices out of sight. Replace bright alarm clocks with dim or red-light versions. Combine with overall dark-room strategy (blackout shades, mask). Prioritize reduction of blue or white LEDs over low-intensity amber lights.
The evidence behind Eliminate electronics LEDs
Even low-level light (<10 lux) during sleep modestly suppresses melatonin and elevates nighttime glucose and heart rate in laboratory settings. Evidence shows clear physiologic sensitivity but small real-world effect unless exposure is persistent or bright. Mechanism: melanopsin-containing retinal cells respond to short-wavelength light even through closed eyelids.
