Modern life rarely goes quiet. Between screens, schedules and a mind that will not stop making lists, most of us are running on shallow rest. Floatation therapy is the antidote: an hour of true weightlessness, warmth and silence that lets your body and mind finally put everything down. This guide covers all of it: what floating is, how it works, what the research says, and how to get the most from your first session.
What is floatation therapy?
Floatation therapy (you will also hear it called floating, flotation REST or sensory deprivation) means lying back in a pod of warm water that is super-saturated with Epsom salt. At Revival, each pod holds around 550kg of magnesium-rich salt dissolved in ten inches of water, warmed to skin temperature, about 35°C.
The salt makes you float like a cork. No swimming, no effort, no holding yourself up. The water is so close to body temperature that within minutes you can barely tell where you end and it begins. With the light and sound faded away, your nervous system gets something it almost never gets: nothing to process at all.
A little history
Floating began in the 1950s, when the neuroscientist Dr John C. Lilly built the first isolation tank to study what the brain does when the outside world goes quiet. The answer surprised everyone: rather than switching off, the mind settles, sorts and restores itself.
The clunky research tanks of those days have evolved into the spacious, comfortable pods used today. Ours are i-sopods, among the largest and most advanced made: 8 feet long and 5 feet wide, with a door and lighting you control the whole time.
What an hour of floating does for the body
- Takes the pressure off. True weightlessness removes every ounce of load from your spine, hips, neck and shoulders. People with back pain, arthritis and fibromyalgia often describe the relief as immediate, and research into floating for chronic pain is encouraging.
- Relaxes working muscles. The warm, magnesium-rich water helps tight muscles let go. Athletes and runners float to ease soreness and support recovery between sessions.
- Calms the system. Studies of floating report lower blood pressure and a slower heart rate during sessions, the signature of a body in genuine rest.
- Sets up a wonderful night's sleep. The night after a float is famous among floaters. Many tell us it is their best sleep in months.
What it does for the mind
With nothing to see, hear or hold up, your nervous system shifts out of fight-or-flight and into rest-and-repair. Stress hormones such as cortisol ease off, and many floaters describe a deep calm that lasts for days.
Deeper into a float, the brain often drifts toward the slow, dreamy theta state, the same territory you pass through on the edge of sleep. It is associated with creativity, problem-solving and that lovely sensation of thoughts untangling themselves. Writers, athletes and busy professionals float for exactly this: they walk out with a clearer head than they walked in with.
Floating is also one of the gentlest ways into mindfulness. The float community calls it training wheels for meditation: the pod removes every distraction, so stillness happens to you rather than being something you have to work at.
Preparing for your float
- Eat light, not none. A small bite an hour or two beforehand is ideal. A rumbling tummy is the loudest thing in a float pod.
- Go easy on caffeine for a few hours before, so your mind can settle.
- Do not shave just before. Fresh shaving plus salt water can tingle. Leave a few hours' gap.
- Come with clean skin and hair, free of oils, lotion and fake tan.
- Arrive 15 minutes early. Time for the tour, your questions and a breath before you begin.

During the session
You have your own private room with a shower. Rinse off, step into the pod, and lie back: the salt does the rest. Door open or closed, light on or off, it is entirely your call, and you can get out at any time. Earplugs are provided and worth using.
The first ten minutes, your mind will chatter. That is normal. Let it run; it usually goes quiet around the time your breathing slows. Some people drift between waking and sleep, some solve problems, plenty simply sleep. There is no wrong way to float.
Afterwards
Shower off the salt, dress slowly and sit with a cup of tea in our relaxation room. Most people leave feeling clear-headed, loose and walking a little slower, in the best way. Drink plenty of water for the rest of the day, and expect a deep sleep that night.
How often should you float?
Once is lovely. Regular is where the real change happens: your body learns to relax faster, your sleep steadies, and the calm starts reaching into the rest of your month. Many of our floaters come monthly, which is exactly why our membership starts at one float a month for €49.
A few honest cautions
Floating is very safe, but a few groups should check first. If you are pregnant, we recommend avoiding the first trimester and having a word with your GP. Salt can sting broken skin, so wait until eczema or psoriasis flare-ups settle. If your blood pressure runs low, check with your doctor, as floating lowers it further. And for safety we are not able to offer floating to people with epilepsy. Every question we are asked about all of this is answered honestly in our FAQ.
