自然的聲音讓您放鬆,因為它們是令人愉悅的音高的持續噪音。
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.
