written by/ May 28, 2021
If wrapping yourself up in a cozy weighted blanket or treating yourself to a quality CBD oil doesn’t do the trick, it’s time to change your bedtime routine.
Namely, some sounds have an incredibly soothing effect on the body. After all, that’s why we rock babies to sleep with pleasant melodies. Specifically, we’re talking about pink noise.
What Is Pink Noise?
You’re probably familiar with white noise, which is mainly used to block out annoying background sounds. For example, your partner’s snores or CPAP machines.
Conversely, pink noise has a relaxing effect on the mind and body. It’s much “deeper” (lower frequency) than white noise and clean of any high-pitched sounds that can disturb and disrupt your sleep.
Also, unlike white noise, pink noise is ”gentle” and contains even, balanced tones that are soothing to the human ear.
In fact, the latest case study shows that pink noise can provide better sleep. That is, improve the sleep phase that refreshes your memory and cognitive performance damaged by chronic insomnia, or even dementia.
The flat repetitive tones of pink noise are all over nature. A few examples include:
- rustling leaves
- steady rain
- waves crashing on a beach
In the end, sound stimulations conducted with pink noise were proven most beneficial for:
- reducing fluctuation in brain waves, increasing sound sleep
- promoting the deep sleep phase
- boosting the slow-wave activity of your brain during sleep
- improving memory and cognition
However, as of now, pink noise sleep aids haven’t yet hit the global insomnia market, but you can try streaming the noise on one of your devices.
