Why it matters
You're not lazy.
You're under-slept.
The foggy mornings, the short fuse, the 3 AM scroll — most of it traces back to the same thing. Slow won't shame you about it. It just helps you fall asleep faster, more nights of the week.
The gap
Two hours short,
every single night.
If you're running on six, you're carrying a quiet debt into every meeting, every conversation, every workout. Slow helps you close the gap one night at a time — by making it easier to actually drift off.
Recommendation: CDC + NIH NHLBI.
The window that matters
Lose the first hour,
lose the whole night.
The deep, restorative sleep your body needs almost all happens in the first stretch of the night. Every minute you spend lying awake is taken straight from that window. Slow's soundscapes quiet the racing thoughts so you cross over sooner — and wake up actually rested.
Layer your sound
Mix two sounds
into one calm.
Start with Brown Noise, add rain, wind, or a distant engine hum. Edit your soundscape, save the mix, and drift off to something that's truly yours.
Sleep timer
Loop for an hour.
Or forever.
Set a timer or let it run until morning. A gentle fade-out keeps the night quiet as you fall asleep.
