Couldn't relax on Your First Float?

Here's Why (and What Helps)

If your first float felt more strange than relaxing, you're not doing it wrong. It's one of the most common things first-timers tell us. Your body and brain have never been in a place quite like a float suite, and they need time to trust it.

I'm Rebecca Harris, PhD, a physiologist and the owner of Kairos Float & Wellness Studio in Greenville, NC. Here's what's going on in your body during a first float, and how to make your next one easier.

Why is it hard to relax during the first float?

Your brain is on alert. Anything new makes your brain pay closer attention. Dark, quiet, and weightless is about as new as it gets. So your brain keeps checking: Am I OK? Is my face above water? That's normal, and it fades with practice.

Your neck doesn't trust the water yet. Most people hold their head up a little without knowing it. The salt water will hold your head up for you, but your neck muscles take a while to believe it. A sore neck or tight upper back after a first float is very common. Use our Float HALO to support your head and neck.

You notice your heartbeat and breathing more. In one study, people with high anxiety floated for 90 minutes. They felt calmer and less tense afterward. But they also became much more aware of their heartbeat and breath during the float (1). If you've never paid attention to your heartbeat before, that can feel odd at first. It's not a sign that something is wrong.

Time feels strange. Many people can't tell if 5 minutes or 50 have passed. In one study, floating made time feel distorted and made people less aware of where their body ends and the water begins. The more people felt that edge fade, the less anxious they felt (2). If you fight that feeling, it can be hard to settle. If you let it happen, it often becomes the best part.

Caffeine is still in your system. Coffee, tea, energy drinks, and pre-workout can all keep your nervous system revved up. Caffeine can stay in your body for hours, and how long varies a lot from person to person (3).

You're trying too hard to relax. This one surprises people. If you keep checking Am I relaxed yet?, your brain stays busy. Relaxation tends to show up when you stop chasing it.

What actually happens in your body during a float?

Even when your first float doesn't feel relaxing, your body is often calming down anyway. In a study of 57 adults, floating lowered blood pressure and slowed breathing compared with watching a relaxing nature film. Heart rate variability shifted toward a more "rest and digest" pattern. That happened in both anxious and non-anxious people (4).

In other words, your nervous system may be settling even while your mind is still busy.

How can I relax more on my next float?

Before you come in:

1. Skip caffeine for 3 to 4 hours before your float. Longer is even better if you're sensitive to it.

2. Don't shave or wax that day. Salt stings fresh skin and small nicks, which pulls your attention away. If you have a small cut, use the Vaseline in your suite to cover it.

3. Eat something light about 30 minutes before, so hunger doesn't distract you.

4. Use the restroom right before you get in.

Once you're in the water:

1. Try your arms overhead. Resting your arms above your head, like you're stretching in bed, takes pressure off your neck and shoulders. Arms by your sides works too. Try both.

2. Let your head drop back. Your ears will be underwater, and that's fine. Use the earplugs in your suite.

3. Keep a light on if you want. You control the lights and music from inside the suite. Our float suites have a door, not a sealed lid, and they're big: 8 feet long and 6.5 feet wide, with a 7.5-foot ceiling.

4. Give yourself 15 to 20 minutes to settle. Wiggle, stretch, and adjust until you're comfortable. Then try to stay still.

5. Follow your breath. You don't need to empty your mind. When thoughts come, notice your next breath and let them drift by.

Is a longer float better for beginners?

Often, yes. During a first float, it can take 30 to 60 minutes just to settle in. A 30-minute session may end right as you start to relax. That's why we suggest 60 or 90 minutes once you know you like it. Our Ultimate Guide to Float Therapy walks through every session length.

Will my second float be different?

For many people, yes. Your brain has seen the space before, and your neck knows the water will hold you. In a trial where anxious and depressed adults floated six times, most stuck with all six sessions. Positive experiences were reported more often than negative ones. When people could choose, they floated for about 75 minutes on average (5).

Every float is a little different, so try not to compare one to the last. Want a step-by-step look at your visit?

Give it one more try

A first float is a bit like a first yoga class. You spend most of it figuring out what you're supposed to do. The second time, you get to actually enjoy it.

If you'd like, tell us at check-in that it's your second float. We're happy to talk through positions, lighting, and anything that felt off last time.
