Hearing the sound of rain falling, beside the running water, always makes people relax and feel more comfortable, like receiving the relaxing nature, which gradually sleeps us well.
Scientists have found that the sounds of nature, like the sound of rain or the sound of water flowing ... are almost like a type of sound called ""white noise"": the sound produced by the combination of all sounds. that humans can hear.
When a noise wakes you up, it is not the noise that wakes you up, but it is the sudden appearance of the noise that catches your attention and wakes you up. If you sleep with the sound of rain, white noise can create a ""cover-up"" effect, making people underestimate the noise, helping to mask many subtle changes that they cannot feel.
