Your Brain Does Something Interesting in a Float

When sensory input drops (no gravity pressure, minimal sound, dim light), your brain can shift into theta wave states.

That’s the same brainwave pattern linked to:
• meditation
• creativity
• daydreaming
• early sleep

Which might explain why people leave floats feeling… different.

✨Why Magnesium Matters✨

Magnesium plays a role in 300+ processes in the body, including muscle function and nerve signaling.
Epsom salt is magnesium sulfate — which is why people often report feeling physically relaxed after a float.
Science can be surprisingly calming 🤷

Things People Don’t Expect About Floating

• Your hair floats around you like you’re underwater in space
• The water is skin-temperature, so eventually you can’t tell where your body ends and the water begins
• You lose track of time in a weird but pleasant way
• You can stretch, crack your back, or just drift

People often walk out saying,
“That was not what I expected… but I loved it.”
Try it for yourself!

Muscle function.

And yes — it feels good too 🤪

💧Floating While Pregnant💧

Growing a tiny human is beautiful… and heavy.

In the float tank, the salt water supports you fully — no pressure on your hips, no pull on your lower back. Just warmth and buoyancy. For many moms-to-be, it’s the first time in months their body feels truly comfortable 🫠

✨ We recommend being past the first trimester

If you’re expecting and curious, we’d love to talk you through it.

Infrared heat works differently than traditional saunas.
Instead of just heating the air, it warms your body directly.
Which means deep, satisfying warmth that lingers.
