Sleep earplugs
Soft silicone earplugs designed for side sleeping, for bedrooms near traffic or a snoring partner.
What the evidence says
Night-time noise is associated with more awakenings and lighter sleep in field studies, and small trials of earplugs (often combined with eye masks) in noisy environments report fewer awakenings and better subjective sleep. Reported attenuation for silicone plugs is around 30–40 dB. Evidence is limited, so keep expectations modest.
How it works
Earplugs function as a physical barrier that attenuates ambient sound waves before they reach the eardrum. By reducing the volume of environmental noise—such as traffic, snoring, or household sounds—they help prevent the auditory cortex from being triggered into a state of alertness during sleep.
What you may get out of it
Sleep Maintenance
By blocking sudden sound spikes, earplugs may help individuals remain in deeper sleep stages and reduce the frequency of nocturnal awakenings.
Improved Subjective Quality
Users frequently report feeling more rested and perceiving their sleep as being of higher quality when environmental noise is consistently suppressed.
Circadian Consistency
Physical sound barriers help maintain a quiet environment during early morning hours, potentially preventing premature waking caused by external light or noise.
What the research consistently shows
Hospital and Critical Care Studies
Research conducted in high-noise environments, such as intensive care units, suggests that earplugs can improve sleep architecture. These studies often observe an increase in REM sleep and a decrease in the time spent in lighter sleep stages when auditory distractions are minimized.
Subjective Sleep Assessment
Systematic reviews of sleep hygiene tools indicate that while physiological data is limited, participant-reported outcomes generally favor the use of earplugs for improving overall sleep satisfaction, particularly when combined with other interventions like eye masks.
Noise Sensitivity and Arousal
Field studies demonstrate that environmental noise is a primary factor in sleep fragmentation. The use of physical barriers is associated with a reduction in cortisol levels and heart rate fluctuations that typically occur in response to nighttime noise.
How to take it
Earplugs should be inserted just before bedtime after ensuring the ear canal is clean and dry. For foam versions, roll the plug into a thin cylinder before insertion; for silicone versions, mold the material to seal the outer opening of the ear canal rather than inserting it deeply. Proper hygiene is essential, and reusable plugs should be cleaned regularly to prevent irritation or wax buildup.
Realistic expectations
Most users notice an immediate reduction in environmental noise, though it may take one to two weeks to become fully accustomed to the sensation of wearing them. They are most beneficial for light sleepers or those living in high-traffic urban areas.
What it doesn't do
Earplugs do not eliminate all sound, as some noise is still conducted through the bones of the skull. They are less effective for low-frequency vibrations and may not be suitable for individuals with active ear infections or significant wax impaction. They will not address internal causes of insomnia such as anxiety or hormonal imbalances.
