자연스러운 소리는 기분 좋은 음조의 지속적인 소음 때문에 마음을 편안하게 합니다.
If you go into the app store on your phone, you can find any number of nature sound apps that are supposed to help you sleep. Natural sounds relax you because they are constant noises of a pleasant pitch. Your brain interprets them as non-threatening noises, which helps reduce your fight-or-flight response. This lowers your stress level and helps you become more relaxed for sleep. Nature sounds and other background noises also help mask sounds that might keep you awake, like traffic or someone moving around in the apartment above you.
