I just came across a website called soundsleeping.com. There I found a relaxation tool that’s fun and easy to use. First you choose some music – e.g. a subtle drumbeat – then you can add 4 different natural sounds, varying from crushing ocean waves to a bird whistle, a campfire or thunder. You then have the option to mix it all together into a blissful blend of sounds. Wanna try? Press here.
