The hotel room that hugs your nervous system
And helps you sleep in the heat
Today I write you post heat wave, where I am deaf from a fan that buzzes like it’s personally offended every time I turn it up past two.
No AC here. Most places in town don’t have it. You learn to live around the heat instead of against it, windows open at the times that matter, shutters closed at the times that don’t, and a fan that hums (badly) through the worst of the afternoon.
It got me thinking about the hotel room.
ATHOME Résidence & SPA, where the Seaweed Suite is introduced on July 9th, doesn’t have AC either. Not an oversight. A choice. It’s an ecolabel hotel, the kind of certification that actually means something, and no air conditioning is part of what that label requires. Heating in winter. Fans and cross ventilation in summer. A building that decided, on principle, not to fight the climate with a machine.
A nice idea that would be uncomfortable in practice.
The hotel rooms where not designed with the same eco materials as the architecture - they were coating in plastic.



Polyester sheets. Synthetic upholstery. Plastic everywhere your skin touches something. None of it breathes the way it needs to. Polyester and nylon trap heat that natural fibers simply let go of, the airflow isn’t there to begin with. And in real heat, your body’s whole cooling system depends on sweat being able to evaporate off your skin. A room wrapped in plastic doesn’t let that happen. It holds the heat against you while you’re trying to wind down for the night.
The room becomes its own small heat wave. One you can’t get up and walk away from.
This is where the seaweed earns its place, and it’s not just because it holds water. That was my first assumption too, seaweed is wet, wet is cool, simple enough. It’s not wrong, just incomplete.
What I learned digging into the material science of seaweed’s thermal behavior, is how it conducts heat, how it holds it and releases it, actually shifts depending on its moisture content and the temperature around it. Not a static, damp thing sitting in a room being passively cool. Responsive. In conversation with the heat, not just absorbing it.
Our Seaweed Suite will do something most rooms don’t come close to.
Cooler isn’t just more comfortable. It’s biologically necessary for real rest. Your core body temperature drops by roughly two degrees over the course of the night, starting a couple hours before you actually fall asleep. That drop is the signal your body uses to begin sleep in the first place. A cooler room works with it. A hot one fights it the entire night.
When a room runs too warm, your body can’t finish that cooling process. You wake more. You lose the deep, slow-wave sleep your brain needs to do its repair work. REM sleep, the stage tied to memory and emotional regulation, takes the first and worst hit from heat.
So when I say the room was built to lower cortisol, I don’t mean it as a metaphor. A room that helps your body cool down is, quite literally, a room that helps your nervous system come down. Toujours les deux.
Most of you reading this won’t be at ATHOME on July 9th. It’s asking a lot of someone to make a trip for a half day event, unless you have a reason to be in the area.
What I want to offer instead is small. Five quiet minutes. Something warm in your hands. A version of the ritual, wherever you actually are. A taste of the experience we will share on the 9th related to my past 30 day hotel experiment where I lived in the hotel room at ATHOME for a month.
During that stay I designed and tested our products, one of them being a beautiful seaweed tea that turns a lovely rose color. A few people commented on the video content that they though I was drinking rosé wine.
I personally love to drink my tea in glass vessels. It elevates the experience. And since we are talking about summer - even better to serve it iced!


The Dulse Rose Beauty Infusion and the Microalgae Marine Glass are how you can be ATHOME at your home. The same tea. A different kind of glass, mouth-blown, made from oyster shells and microalgae, no two alike. You can’t book this Seaweed Suite yet, but you can own this part of it.
