What's all the noise about White Noise vs. Pink Noise for sleeping? As with everything, it's all in the way your brain is programmed.

I was married to a man who snored loudly so I've slept with a white noise machine for decades.

White and pink noise machines are said to promote deeper sleep and improve memory. That makes sense as I have always slept 9 consecutive hours with my "noise machine" (pic above).

The first time I used a white noise machine (the original model with only white noise) ... I had two visuals or memories ... I was asleep on a spaceship or asleep in a simulation chamber on a spaceship drifting through space-time. That's probably true.
