Used to blast white noise at night for sleep, now I run a box fan instead

Switched six months ago after my old sleep tracker app told me white noise spikes my heart rate. Anybody else find the low rumble of a fan works better than digital noise?

yeah I actually read something about this recently. there was this sleep doctor on a podcast talking about how the human brain processes natural sounds different than digital ones. he said white noise machines can actually keep your brain in this low level alert state because it's too uniform or something? the fan rumble has more variation to it apparently. I switched to a box fan a few months back and my deep sleep went up like crazy on my tracker. plus it's way cheaper than replacing those white noise gadgets every year when they break.

Man that feels like overthinking it, a white noise machine is fine for most people lol.
