Sixty minutes. Skin-temperature water. One thousand pounds of magnesium salt holding you weightless in the dark. Walk out and into the deepest night of sleep you've had this year.
The Chronotype Test · By Dr. Michael Breus
Dr. Breus's clinical research identifies four chronotypes — biological sleep-wake patterns hard-coded into your circadian rhythm. Your chronotype determines when you should float, how often, and what to expect. Five questions. Sixty seconds.
The Science of Feeling Great
Float therapy isn't relaxation theater. It's a measurable shift — magnesium absorption, cortisol drop, theta-state brainwaves — built into one hour of complete stillness.
1,000 pounds of Epsom salt — magnesium sulfate — dissolved in 10 inches of skin-temperature water. The mineral most adults are deficient in, delivered transdermally, for 60 uninterrupted minutes.
No light, no sound, no gravity. Sensory load drops to near-zero and your sympathetic nervous system stands down. Cortisol drops measurably within the first 20 minutes — and stays low into the night.
Most adults only touch theta-state brainwaves at sleep onset and during REM. In the pod, you spend most of an hour there. The body remembers how to drop in — and brings that memory home.
What Changes
The pod is the closest thing your nervous system has to a factory reset. Cortisol drops measurably during the float and stays low for hours. Most floaters report falling asleep the same evening in under fifteen minutes — without the wind-down ritual, the magnesium gummies, or the second drink.
Slow-wave sleep is the phase the body uses to actually repair — to consolidate memory, clear metabolic waste, restore the immune system. Regular floaters spend more minutes there per night, with measurable carryover for three to five nights after a single session.
The most common pattern in modern insomnia isn't sleep onset — it's middle-of-the-night arousal. Lower nighttime cortisol and balanced magnesium make a quieter sleep, and an easier path back down when something does wake you.
What is Float Therapy?
Floating is effortless. You don't need to know how to swim or meditate. The pod does the work. Over 1,000 pounds of Epsom salt creates a perfectly buoyant, weightless environment that supports your entire body.
Let your muscles release. Your mind quiet down. Your nervous system reset. And yes — it's even safe to drift off to sleep on the water.
Clinical Partnership
Dr. Michael Breus — known internationally as The Sleep Doctor — partnered with True REST to design Float for Sleep: a clinically structured protocol that pairs flotation-REST with chronotype-aligned sleep coaching. The protocol targets the three mechanisms that drive insomnia in modern adults: elevated nighttime cortisol, magnesium deficiency, and sympathetic-nervous-system overdrive.
Every Float for Sleep session follows his protocol — pre-float wind-down, sixty minutes of zero-gravity flotation, post-float integration. The goal is not a single great night. The goal is durable sleep architecture you keep.
I was running on five hours, three coffees, and a prescription I didn't want to take. After my first float, I slept eight straight hours for the first time in two years. I'm a member now. It's not a mystery — it's a habit.
