Summary

Sound therapy utilizes broadband noise (e.g., white, pink) to mask disruptive environmental sounds that can fragment sleep. By creating a consistent auditory environment, it can reduce sleep latency and nocturnal arousals, thereby promoting deeper, more restorative sleep stages critical for glymphatic clearance, cellular repair, and hormonal regulation.

Purpose

Masks disruptive sounds to improve sleep quality and consistency.

Card Summary

Utilizes consistent, broadband sound to mask disruptive noises, potentially improving sleep continuity and depth, which are crucial for nightly repair and brain health.

Impact

Score:
4.5
Justification:
Improves sleep quality, a foundational pillar of health, but indirect longevity impact.

Evidence

Grade:
B
Score:
6.5
Justification:
Multiple small human trials show improved sleep onset and reduced awakenings.

Safety

Score:
1
Justification:
Very safe; primary risk is potential hearing damage from excessive volume.

Flags

  • Volume should be kept below 50 dB to avoid potential long-term hearing damage.
  • Some individuals may find it disruptive rather than soothing, or develop a dependency.
  • Pink or brown noise may be preferable for some due to less high-frequency energy.

Verdict

A low-risk, effective tool for improving sleep quality and consistency.
