Our Story | 18pointthree
My name is Calum and I am the founder of 18pointthree. A few years of drinking, partying and not thinking about my health caught up with me. My gut crashed and my nose blocked up with it. On top of that, something structural in my nose narrows it, so lying down I couldn’t move enough air through it. I learned to sleep with my mouth open. I was waking about twenty times a night, roughly every half hour, with a mouth so dry I reached for water every time.
So I read everything I could find on gut health, breathing and sleep. Fixing my gut eased the congestion. Nasal strips opened my nose up at night, and mouth tape reminded me to keep my lips together. Now I wake once or twice.
But there was a problem — every product I tried either irritated my skin, fell off during the night, or was full of harsh adhesives. I couldn’t find anything that worked the way it should.
That’s why I started 18pointthree — a sleep-focused brand built from personal experience and relentless testing. Our name comes from the optimal bedroom temperature for sleep: 18.3°C. It’s a reminder that great sleep is a science — and getting it right changes everything.
Our mission is simple:
Create the most effective, skin-safe sleep tools on the planet, and build the go-to store for anyone who wants to sleep better, naturally.
Whether it’s non-toxic mouth tape that actually stays on, nasal strips that don’t peel your skin, or other carefully curated sleep essentials — every product we offer is something I use myself.
Because when you sleep better, you live better.
