Ask people what they like to fall asleep to and rain comes up again and again. There is nothing mysterious about why. Rain has a few plain properties that happen to suit a tired brain.
It is steady
Your hearing keeps working while you sleep. What tends to wake you is a change in sound, such as a door closing, a car passing or a voice in the next room, more than the overall level of noise.
Rain barely changes. It is a broad, even wash of sound with no sharp edges, so it gives your ears a constant background. Against that background, small noises stand out less and are less likely to pull you back awake.
It has nothing to follow
Music has a melody and podcasts have a story. Both give your mind something to track, and tracking keeps you awake. Rain has no tune and no plot. You can listen to it for a minute and then stop noticing it, which is what you want from a sleep sound.
It feels safe
Many people simply find rain comforting. Being warm and dry indoors while it is wet outside is a pleasant feeling, and for a lot of us rain is tied to memories of staying in. A sound you associate with shelter is an easy one to relax to.
That part is personal. Some people find rain gloomy, or it makes them need the bathroom. If that is you, a fire or running water may suit you better. Our guide to choosing between white noise, rain and fire compares them.
How to use rain sounds well
Keep it quiet. The sound should sit below the level of a conversation, only just there. Louder is not better, and very loud sound all night is not good for your hearing.
Use a speaker, not earbuds. Sleeping in earbuds can be uncomfortable and hard on your ears. A phone speaker across the room is enough.
Let it run all night, or fade out slowly. A sound that stops suddenly at 3 a.m. is itself a change, and it can wake you. Either let it loop until morning or use a timer that fades out gently.
Start it before you get into bed. If the rain is already playing while you brush your teeth, it becomes part of winding down. After a week or two the sound itself starts to feel like a cue for sleep.
Pick steady rain. Thunderstorms are dramatic and full of sudden changes. For sleep, choose rain that sounds much the same from one minute to the next.
Rain you can look at
A sound works better when you can picture where it is coming from. In migg, rain comes with a room: a high-rise apartment in Tokyo with drops running down the glass, a glass house in the woods, the back of a van in a forest. You pick the place, the rain plays until morning and your koala falls asleep when you do.
