About Us

My name is Calum and I am the founder of 18 Point Three. I used to live a pretty reckless lifestyle — drinking, partying, and not giving much thought to my health. Eventually, it caught up with me. My gut health crashed, and with it came a constantly blocked nose that made it nearly impossible to sleep. I’d wake up every hour with a painfully dry mouth from breathing through it all night. I didn’t realize how badly poor sleep was affecting every part of my life — until I had no choice but to fix it.

That’s when I started researching everything I could about gut health, breathing, and sleep. As I worked on healing my gut, my nasal congestion started to ease up. I also began experimenting with mouth tape and nasal strips, and for the first time in years, I felt what deep, uninterrupted sleep actually felt like.

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 18 Point Three — 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.

Join us on the journey while we create the number one shop for all your sleep needs!

Because when you sleep better, you live better.
