Sleep and relaxation sounds

Mix rain, sea, fireplace or noise and set the volume of each one. The sound is made on your device, keeps playing with the screen locked and turns itself off when you choose. Further down there is a guide for slow breathing.

Slow breathing

Follow the circle: it grows as you breathe in and shrinks as you breathe out.

What is known

• Noise for sleep: a review of 38 studies found that the evidence that continuous noise improves sleep is of very low quality.Source: Riedy et al., Sleep Medicine Reviews, 2021.
• Pink noise: in a lab study with 11 people, short sounds played in time with the slow waves of sleep boosted those waves and next-day memory. A continuous sound, like the one on this page, does not do the same.Source: Ngo et al., Neuron, 2013.
• Binaural beats: a meta-analysis of 22 studies found small to moderate effects on memory, attention and anxiety, with large differences between studies. They only work with headphones.Source: Garcia-Argibay et al., Psychological Research, 2019.
• 432 Hz, 528 Hz and other frequencies: studies are few and small, and none shows that they treat illness.Source: PubMed search.
• Slow breathing: a review links breathing about 6 times a minute to more relaxation in small studies, and a meta-analysis of 12 trials found a small to moderate drop in stress.Source: Zaccaro et al., 2018 and Fincham et al., Scientific Reports, 2023.
• Volume: the WHO recommends background noise in the bedroom below 30 dB(A) for sleep. Keep the volume low.Source: WHO, Guidelines for Community Noise, 1999.
