The 30-Day Float Experiment

My name is Mark, and I run Float Boston. 

The other day I posted a blog on what “could” happen if one was to float every day for a month. Hypothetical, but science backed. It perked by curiosity as to what would really happen.

This is a personal experiment to understand what floating every day for 30 days actually does for the nervous system, stress response, sleep, and overall recovery — using both daily wearable data and before-and-after lab testing.

I’ll float once per day for 30 consecutive days and share what happens in real time — the good, the neutral, and anything unexpected. You’ll find that information as well as the data from my Oura ring and Superpower at the end of this page and it will be updated daily starting on the first day end ending when I get my final blood test results.

A little about how I treat my body and mind before we begin, I feel this is important; I already get enough sleep, but my sleep scores are all over the place. I use to work out quite a lot, but since taking over Float I have been limited to walks in the park. I do not meditate, and I try to float weekly but December to now was rough and I think I only got 3 sessions in. My Oura Ring and Apple Watch tell me that I need to relax more, and yet they also tell me to work out more. Finally, In December I went from 5-8 caffeinated beverages per day down to 1. 

My first blood draw is on February 9th, and that’s when this experiment begins. 

If you want to do your own float challenge, we’re offering it for $650 ($21/float) and you can use our link to get $50 off the bio-marker testing at Superpower. There is a limit of 10 active challenges at a time to keep the tanks open for regular clients. If you complete the 30 floats in 30 days you’ll get your choice of $50 floats for one year, or a 2 float/month membership for $75. Post challenge testimonial videos are worth a $100 gift certificate too! Click here to join!

How I’m Measuring This

Daily Tracking (Oura Ring)

I’m using my Oura ring to track how my body responds day by day:

• Sleep score

• Heart rate variability (HRV) trend

• Resting heart rate

• Daytime stress minutes vs calm/restored minutes

• Sleeping heart rate (range)

I’ll share short daily updates and weekly summaries focused on trends, not daily noise.

Biological Testing (Superpower)

To see what’s actually changing under the hood, I’m running comprehensive bloodwork through Superpower before and after the 30 days.

Testing schedule:

• Baseline labs: Day 0 (before starting daily floats)

• Post labs: Day 29–31 (after completing the challenge)

Both draws will be done under similar conditions (time of day, fasting state) to keep the comparison clean.

From the full panel, I’ll focus publicly on markers related to:

• Inflammation

• Stress biology

• Metabolic health

• Cardiovascular risk

• Energy and nutrient status

Superpower tests 100 different markers, but these were the most important in terms of the experiment. If I see any odd-ball changes in other markers that I did not anticipate, I’ll post those as well. 

Why I’m Sharing This

Most wellness claims live in anecdotes.

This is about pairing how I feel with what my body is doing biologically.

The goal isn’t to prove floating fixes everything — it’s to see what actually moves when the practice is done consistently.
