White Noise: How It Helps Sleep
White Noise Machines
White noise is sounds that are between 20 and 20,000 hertz, played at a consistent volume. It can be very useful if you have insomnia or just have trouble falling asleep. White noise is something our brain can focus on instead of getting distracted by random noises. Often, loud noises aren’t what wake people up, but the change in sound. White noise helps your brain ignore it and stay asleep. White noise helps your brain relax, switches off your mind, and blocks loud noises. Our brains consider white noise less important than pure tones, but more important than random sounds. That explains why it muffles the random sounds you might hear but isn’t loud enough to wake your brain up. Studies show that listening to sounds over 85 decibels can be damaging over time, so it is super important to keep the volume at a safe level. A pretty good level is around 45 decibels. White noise helps with memory, focus, and reaction time. Not enough sleep can lead to earlier deaths as well. As you listen to white noise, your brain will associate it with sleep, which is why it is good to use it consistently. White noise also can make hearing better. If you start the white noise at a consistent time and build a sleep routine, it will help your sleep a ton.
