Siim Land: This Popular Sleep Hack Might Be Ruining Your Sleep
Peer-Reviewed Research
Key Takeaways
- Pink noise reduces REM sleep (critical for memory) and worsens sleep quality when combined with environmental noise.
- Earplugs outperform pink noise for blocking environmental noise, preserving deep and REM sleep.
- White noise may help infants cry less, but evidence for adult sleep improvement is weak and risks hearing damage at high volumes.
- Avoid chronic noise exposure (>50dB) during sleep—prioritize stable, quiet environments for optimal recovery.
Products & Gear Mentioned
- Bon Charge Red Light Hat (boncharge.com) for scalp therapy/hair growth.
- Red light therapy face masks/panels (studies show collagen/wrinkle improvement).
Notable Quotes
“Environmental noise plus pink noise at 50 dB reduced REM sleep by 29 minutes—the worst sleep quality outcome.”
Bottom Line
Use earplugs (not pink noise) in noisy environments, and prioritize quiet, stable sleep conditions. Avoid chronic noise masking—it harms sleep architecture and hearing long-term.
