There's nothing more frustrating in the world than being exhausted but just not being able to sleep.
And when we do eventually nod off, getting a solid eight hours sleep is almost impossible for a lot of people, with the distraction of mobile phones and the stresses of modern day life.
Now, scientists say that pink noise could be exactly what the restless need to get a good few hours of kip.
According to a study in Frontiers in Human Neuroscience pink noise is less intrusive than white noise and could lead to a better, deeper sleep. They even reckon that if used continuously, it could improve your memory too.
The study tested people listening to pink noise as they slept, and found that those participants reported feeling a lot more rested.
The pink noise participants also performed three times better in memory tests and cognition tests compared to those who just slept normally.
No better night to try it out than tonight!
