Ever since I was a kid I have always had a fan on while I sleep. Through my own experiments I have discovered that without a fan I wake up to any sudden noise, and the sleep was actually not a restful. When I sleep with a fan I sleep like a rock the white noise in the background drones out all the other sound, which is actually a bad thing for me because I never hear my alarm in the morning. After researching this I found that the brain craves sensory input, and having a constant white noise in the background actually allows your brain to stop thinking as much so it can rest. The white noise feeds the brains need for sensory input and allows a person to sleep better. Seth S. Horowitz, a neuroscientist said that you still hear while you are asleep (Popular Science). So the reason that I am a heavy sleeper is because the white noise cancels out all the other noises, which allows me to sleep through most things.
Which is more effective: White noise or Pink noise?
It really comes down to personal preference, but a study recently discovered that when exposed to pink noise while sleeping there is a “significant enhancement in the percentage of stable sleep time compared to the control group” (NCBI). The control group in this case is the people sleeping in silence.
White noise is also effective when attempting to sleep. In a study done with newborns, 80% of the newborns fell asleep within five minutes due to the white noise (NCBI). Comparing babies and adults maybe be a bit of a stretch, but as I said before it is all about personal preference. Getting a good night sleep is critical for everyone especially college students. Sleep lose can actually decrease academic performance (University Health Center). Sleeping is very critical to a healthy lifestyle without it you do not feel one hundred percent, so if you find yourself having trouble sleeping try using some white noise or even pink noise.
