If you've ever dreamed of drifting weightlessly like an astronaut in outer space while melting away your stress and pain, float therapy might be the out-of-this-world experience your body and mind crave. Whether you’re battling anxiety, recovering from chronic pain, or simply seeking profound relaxation, stepping into a float tank could be the wellness game-changer you didn’t know you needed.
Let’s dive deep into the float therapy benefits, bust common myths, explore the science, and uncover why people are swapping spas for sensory deprivation tanks.
What Is a Float Tank? A Portal to Peace
A float tank—also known as a sensory deprivation tank, isolation tank, or flotation tank—is a lightproof, soundproof pod filled with skin-temperature salt water containing about 1,000 pounds of Epsom salt (aka magnesium sulfate [1]). This creates a zero-gravity environment that allows you to effortlessly float weightless, eliminating external stimuli and immersing you in pure sensory isolation.
This form of restricted environmental stimulation therapy (REST) helps the body and mind achieve a deep state of calm, similar to meditation or even sleep. Many floaters say it’s like hitting a “reset” button on their nervous system.
Benefits of Flotation Therapy: Why You’ll Keep Coming Back
The benefits of float therapy are both physical and mental. Here's what you can expect from regular float sessions:
1. Relieve Stress and Anxiety Naturally
Floating may help modulate stress hormone levels, such as cortisol, based on preliminary research, and activate the body’s relaxation response. This is ideal for those suffering from chronic stress, anxiety disorders, and sleep difficulties. A single session can lead to a significant reduction in mental tension and anxiety [3].
2. Ease Chronic Pain and Muscle Tension
The near-weightless environment created by floating allows tense muscles, aching muscles, and joint pain to fully relax. The magnesium sulfate in the water also aids in reducing inflammation, lactic acid, and muscle tension, making it popular among athletes for pain reduction and enhancing athletic performance.
3. Boost Mental Health and Brain Function
Without distractions, the human brain can reboot, leading to improved focus, clarity, and a mental boost. Many report improved mental clarity and emotional resilience after regular use—clear examples of float therapy benefits for the mind and mood.
4. Improve Sleep Quality
People suffering from sleep disorders and stress-related insomnia often report better sleep after floating. The experience encourages the brain to enter theta brainwave states, similar to those experienced before sleep, making it easier to fall asleep at night.
5. Lower Blood Pressure and Improve Circulation
Float therapy may support circulation and overall well-being. This contributes to long-term health benefits such as cardiovascular support and improved overall well-being.
Myths of Flotation Therapy: What It’s Not
Like all forms of alternative medicine, floatation therapy isn’t immune to myths and misconceptions. Let’s clear some up:
Myth 1: You Can Drown in a Float Tank
The water is only 10–12 inches deep, and the dense Epsom salt makes you float effortlessly. Drowning? Extremely unlikely.
Myth 2: It’s Claustrophobic
Most modern float spas offer spacious floatation tanks [2] or even open float rooms. Plus, you're in complete control—you can open the door or turn on the light at any time.
Myth 3: It’s Only for the “Woo-Woo” Crowd
Many researchers and some practitioners, including psychologists and military programs, are exploring restricted environmental stimulation techniques as complementary approaches.
Myth 4: It’s Unsanitary
Float spas use medical-grade filtration systems that sanitize water between each use, often using UV light, ozone, and hydrogen peroxide.
Scientific Research on Flotation Therapy
This isn’t just hype—there’s real science behind it.
A randomized controlled pilot trial published in BMC Complementary Medicine and Therapies found significant improvements in anxiety, depression, and sleep quality among participants who used sensory deprivation tank therapy.
Other studies on environmental stimulation therapy show that floating leads to lowered stress hormone levels, improved brain function, and reduced physical pain. It’s also shown promise in managing high blood pressure, reducing chronic pain, and may assist in skin recovery, although it is not recommended for open wounds.
Final Thoughts: Is Float Therapy Worth It?
Float therapy might be your sanctuary if you're looking for a way to relieve pain, manage stress, or just take a break from a chaotic world. Whether you call it a sensory deprivation tank, floatation tank, or tank therapy, the physical benefits and mental relaxation are worth every float.
So, the next time life feels too heavy, consider stepping into a zero-gravity pod and letting your body and mind drift into deep, profound relaxation. You might emerge feeling lighter, in every sense of the word.

FAQ’s
What are the side effects of float therapy?
Most people experience positive effects, but mild side effects can include nausea, dizziness, or lightheadedness, especially if dehydrated or overstimulated afterward. Rarely, skin irritation from Epsom salt may occur.
Who should not float?
Avoid float therapy if you:
- Have open wounds or skin infections
- Are under the influence of drugs/alcohol
- Have uncontrolled epilepsy or severe claustrophobia
- Recently dyed your hair or used tanning products
Have low blood pressure (consult your doctor first)
Why adjustment to magnesium absorption or sensory changes?
Nausea may result from:
- Sensory overload upon exiting
- Dehydration or low blood sugar
- Motion sickness-like effects if sensitive to the zero-gravity environment
- Detox response due to magnesium sulfate
Should I shower after a float?
Yes. Showering after removes salt water from your skin and hair, preventing irritation and helping your skin return to normal balance.
Can I float every day?
Yes, but for most people, 1–2 sessions per week are sufficient. Daily floating is safe if your skin tolerates the Epsom salt, and you’re experiencing ongoing physical pain or stress relief.
