Pink noise is used to help you focus and stop distractions and also to help you sleep.
Pink noise is a constant sound in the background which filters out things that distract you, like people talking or cars going by, so they don't interrupt your sleep.
You may also hear pink noise called ambient noise.
Like white noise, it's a steady background hum that may give you a better night's sleep.
Pink noise is a type of background noise that contains a random assortment of all the audible frequencies, with more power in the lower frequencies.
An example of pink noise would be rain sounds and Wind blowing through trees, Rustling leaves and Ocean waves hitting the beach.
For some people it's better for them to sleep in silence while for others it's better to sleep with some background noise such as white noise.
Some people including myself prefer to sleep with a bit of noise in the background as pure silence can bother us and make it hard to sleep.
Others may have a hard time sleeping when there's noise in the background.
Rain sounds do help some people sleep.
When it comes to sleep everyone is different and while some people can sleep to rain sounds or other noises other people may find it hard to sleep with rain sounds or other white noise.
As for myself I find that I sleep much better when it's raining out or when I use rain sound white noise from YouTube all night.
I sleep much better with some form of noise than in pure silence.
My brother on the other hand has to have complete silence but for me complete silence keeps me awake.
Even when I was a baby and little kid I would not sleep good unless some music was playing or some noise was around.
While most people want people to be quiet when a baby or toddler is sleeping It was actually the opposite for me as I would sleep better when people were talking and making noise or the TV, radio etc were on.
The rhythmic, quiet sound of rain can be a remarkably good lullaby for people who are trying to sleep.
Some studies have shown that the sound of rain actually causes the brain to relax unconsciously, pushing it towards a state of sleepiness.
Naturally, this is not the case when it's thundering.
White or pink noise can help people sleep by blocking out outside sounds and masking disruptive sounds.
Research has found that sleep disturbances caused by noise pollution have health consequences for our biological systems.
