What Is Floatation Therapy?
Floatation therapy, also known as sensory deprivation or REST (Restricted Environmental Stimulation Therapy), is a remarkable wellness experience where you float effortlessly in a specially designed tank or pod filled with water saturated with Epsom salts. The concentration of salt — typically around 500 kilograms in a small tank — creates water so buoyant that you float effortlessly on the surface, as if suspended in space. The water is heated to skin temperature (approximately 35.5°C or 95.5°F), so after a few minutes, you lose the sensation of where your body ends and the water begins. Combined with complete darkness and profound silence, every sensory input that ordinarily bombards your nervous system — gravity, sound, light, touch, temperature — is reduced to near zero. In this state of sensory minimisation, your brain enters a deeply restorative mode. The constant processing of external stimuli that consumes most of your mental energy shuts down, freeing up resources for internal healing, creative thinking, and profound relaxation. What emerges is an experience that is uniquely personal — some floaters journey inward through deep meditation, others experience vivid visual imagery or creative breakthroughs, and some simply fall into the deepest sleep they have ever had. At Meraki Spa, we provide a premium floatation experience with state-of-the-art tanks, meticulous sanitation protocols, and a serene environment that allows you to fully surrender to the float.
the science of floating for stress relief.
The History and Science of Floatation Therapy
Floatation therapy was developed in 1954 by Dr. John C. Lilly, a neuroscientist and physician studying the nature of consciousness. His original sensory deprivation tanks were designed to investigate what happens to the mind when all external stimulation is removed. Lilly discovered that rather than going mad, subjects entered deeply relaxed, meditative states with enhanced creativity and self-awareness. Over the decades, the technology evolved from research instruments to therapeutic tools. Modern float tanks are designed for comfort, safety, and hygiene, with sophisticated filtration and sanitation systems. The science behind floatation is compelling. When the brain no longer has to process sensory input — vision, hearing, touch, proprioception, thermal sensation — it shifts into a different mode of operation. EEG studies show that floating increases theta and alpha brainwave activity. Alpha waves (8–12 Hz) are associated with relaxed alertness. Theta waves (4–8 Hz) are even more fascinating — they occur during deep meditation, REM sleep, and the moments before falling asleep. In this theta state, the brain is highly suggestible, creative, and capable of profound insight. The reduction of cortisol — the primary stress hormone — during floating is dramatic. Research published in the journal BMC Complementary and Alternative Medicine found that a single 45-minute float session reduces cortisol levels by an average of 21%, with even greater reductions after multiple sessions. Simultaneously, endorphins and dopamine — the feel-good neurotransmitters — increase, creating a natural high that can last for hours or days after the session.

The Remarkable Health Benefits of Floatation Therapy
Floatation therapy's benefits extend across physical, mental, and emotional dimensions. Profound Stress Relief: This is the most celebrated benefit. The combination of weightlessness, sensory minimisation, and warm water triggers the deepest relaxation response most people ever experience. Stress melts away within minutes of entering the tank. Anxiety and Depression Management: Multiple clinical studies have shown that regular floating significantly reduces symptoms of anxiety and depression. The theta brainwave state facilitates emotional processing, while the reduction in cortisol and increase in dopamine create a neurochemical environment that supports mental health. Enhanced Creativity and Problem-Solving: With external distractions eliminated, the mind can explore ideas freely. Many artists, writers, musicians, and entrepreneurs use floatation therapy as a creative tool — emerging from sessions with new perspectives, solutions to problems, and bursts of inspiration. Deep Muscle Relaxation and Pain Relief: In zero-gravity conditions, muscles can fully relax without fighting gravity. This is particularly beneficial for back pain, neck tension, and conditions like fibromyalgia. The Epsom salts (magnesium sulphate) also absorb through the skin, reducing muscle inflammation and soreness. Improved Sleep Quality: Floating resets the sleep cycle. Many people with chronic insomnia experience their best sleep in the float tank and report improved sleep patterns for days afterward. Accelerated Physical Recovery: Athletes use floatation therapy to speed recovery between training sessions. The combination of muscle relaxation, reduced cortisol, and increased blood flow accelerates healing of micro-tears and reduces inflammation. Heightened Self-Awareness and Mindfulness: Without external distractions, you become acutely aware of your own thoughts, feelings, and bodily sensations. This cultivates a mindfulness practice that carries over into daily life.

What to Expect During Your First Float at Meraki Spa
Your floatation journey begins before you even enter the tank. Upon arrival at Meraki Spa, you will be given a tour of the float room and a thorough orientation. You will be asked to shower thoroughly before floating — this is important both for hygiene and because clean skin floats more comfortably. The float room is completely private and lockable. You can choose to float with the tank lid open or closed. Most first-timers start with the lid open or partially open, gradually closing it as they become comfortable. The tank is spacious — far larger than you might imagine — so there is no feeling of claustrophobia for most people. You enter the tank wearing nothing (or swimwear if you prefer) and lie back. The sensation of weightlessness is immediate and surprising — you simply float, with your face above water and your ears submerged. The water is perfectly warm, matching your skin temperature. The air temperature is also matched, so after a few minutes you cannot feel where your body ends and the environment begins. You can control the lights and music from inside the tank. Most people turn everything off after the first few minutes. The first float is often an adjustment period as your mind learns to let go. Some people feel restless initially; this passes. Time perception changes dramatically — a 60-minute float may feel like 15 minutes or 3 hours. Our attendants gently signal when your session is ending with soft music and lights that gradually come up. After the float, you shower again and are invited to relax in our post-float lounge. Many guests describe feeling reborn — physically weightless, mentally clear, and emotionally centred.
Floatation vs. Meditation: How They Compare
Both floatation therapy and meditation are powerful tools for mental well-being, but they work differently and can complement each other beautifully. Traditional meditation requires discipline, practice, and the ability to sit with discomfort — physical discomfort from sitting still, mental discomfort from confronting the restless mind. It takes most people months or years of consistent practice to reach deep meditative states. Floatation therapy creates the conditions for deep meditation automatically. The physical support is so complete that the body has nothing to do. The environment is so minimised that the mind has nothing to hold onto. Even someone who has never meditated can experience a profound meditative state within their first session. However, the float experience is finite — once you leave the tank, the external stimulation returns. The skills of mindfulness and presence developed through meditation help maintain the float benefits in daily life. For this reason, many regular floaters also maintain a meditation practice. The two work synergistically: floating deepens your meditation, and meditation extends the float benefits. At Meraki Spa, we often recommend that newcomers try three floats in the first month to fully understand the experience, then decide how to incorporate floating into their ongoing wellness routine.
Tips for Getting the Most Out of Your Float
To maximise your floatation experience, consider these practical tips. Avoid caffeine and heavy meals before your session — a light meal two hours before is ideal. Caffeine stimulates the nervous system and can make it harder to settle into the relaxation state. Avoid shaving for at least 24 hours before your float — even tiny nicks will sting from the high salt concentration. Do not put any products in your hair (gel, spray, etc.) as they can degrade the water quality. Remove contact lenses and jewellery before entering the tank. The water is sterile and heavily salted, so there is absolutely no risk of infection, but contact lenses should not be exposed to the water. Use the earplugs provided — earplugs protect your ears from the salt water and also enhance the sensory deprivation by blocking sound. Trust the process — if you feel restless or your mind races, that is normal. Do not try to force relaxation. Just observe your thoughts without judgment. The theta state will come when you stop trying. Stay hydrated before and after floating. The Epsom salts have a mild osmotic effect, and drinking water before and after enhances the detoxification benefits. Try to have a calm schedule after your float. The profound relaxation continues for hours after you leave the tank. Give yourself time to integrate the experience.
Frequently Asked Questions
Will I feel claustrophobic?
a beginner\u2019s guide to sensory deprivation tanks.
Most people do not. The tanks are spacious — much larger than a bathtub — and you have full control. You can leave the lid open, and the door is never locked. If you feel uncomfortable at any point, you can simply get out.
Will my skin wrinkle?
Surprisingly, your skin does not wrinkle in the float tank! The high salt concentration prevents the osmotic effect that causes wrinkling in fresh water. You emerge smooth-skinned and soft.
Is it sanitary?
Absolutely. The salt concentration in the float tank is higher than the Dead Sea — approximately 500 kg of Epsom salts in the water. Nothing can survive in that environment. The water is filtered multiple times between sessions and fully sanitised. At Meraki Spa, we maintain the highest sanitation standards.
Can I float if I'm pregnant?
Many pregnant women find floating incredibly beneficial — the weightlessness provides relief from the physical burdens of pregnancy, and the relaxation benefits maternal and foetal health. However, we recommend consulting your healthcare provider first, especially if you have any pregnancy complications.
What if I fall asleep?
That is perfectly fine and very common! You cannot drown in a float tank — the buoyancy is so high that your face automatically stays above water. The attendant will gently wake you when your session ends.
