Float therapy, also known as sensory deprivation or floatation therapy, involves immersing oneself in a float tank or pod filled with a highly concentrated saltwater solution. The individual floats effortlessly on the surface of the water, which creates a sense of weightlessness and eliminates external sensory stimuli. Here is a detailed explanation of float therapy, its benefits, working mechanism, types, scientific theories, research, potential drawbacks, and considerations for finding a reputable float therapy center or practitioner:

Float therapy offers several potential benefits for both physical and mental well-being:

1.Deep Relaxation: The float tank's environment promotes deep relaxation by reducing sensory input, allowing the body and mind to reach a state of profound calmness and relaxation.

2.Stress Reduction: Float therapy has been reported to reduce stress levels and improve stress-related symptoms by activating the body's relaxation response and decreasing the production of stress hormones.

3.Pain Relief: The buoyancy in the float tank relieves pressure on joints and muscles, offering relief from chronic pain conditions, including fibromyalgia, arthritis, and muscular tension.

4.Enhanced Sleep: Float therapy has shown promising results in improving sleep quality and combating insomnia by reducing physical and mental tension and inducing a state of relaxation.

5.Mental Clarity and Creativity: Floating can enhance mental clarity, focus, and creativity by providing a tranquil and distraction-free environment, allowing the mind to wander and explore.

6.Improved Athletic Performance: Float therapy may aid in sports recovery and performance by facilitating muscle relaxation, reducing lactic acid buildup, and enhancing mental focus.

Float therapy works by immersing the body in a sensory-restricted environment. The float tank or pod is filled with a warm solution of water and Epsom salt, creating a buoyant environment that mimics the feeling of weightlessness. The high salt concentration in the water allows the body to effortlessly float on the surface.

The tanks or pods are typically soundproof and lightproof, creating an environment devoid of external distractions. The water and air temperature are carefully regulated to match the individual's body temperature, further enhancing the sensation of sensory deprivation.

There are different types of float therapy available:

1.Traditional Float Tanks: These tanks are enclosed and offer complete sensory isolation. They are usually large enough for a person to stand or move around inside.

2.Float Pods or Cabins: These are more compact and sleek versions of float tanks. They provide a confined space for floating and sensory deprivation.

3.Open Float Pools: These pools are larger and do not provide complete sensory isolation. They are suitable for individuals who prefer a more open and spacious environment.

The therapeutic effects of float therapy are supported by several scientific theories:

1.Restricted Environmental Stimulation Theory (REST): According to this theory, when external stimuli are minimized, the brain shifts its focus from processing sensory information to engaging in internal processing, leading to relaxation and rejuvenation.

2.Neurochemical and Hormonal Changes: Float therapy has been associated with changes in neurochemicals and hormones, including increased endorphin and dopamine release, reduced cortisol levels (a stress hormone), and increased production of relaxation-inducing chemicals.

3.Theta Brainwave State: The floatation environment is conducive to producing theta brainwave patterns, associated with deep relaxation, creativity, and enhanced cognitive processing.

Float therapy has been the subject of various research studies, exploring its effects on different conditions. Scientific studies have found positive outcomes related to stress reduction, pain relief, anxiety reduction, and improved sleep quality. However, more extensive research is needed to fully understand and validate the therapeutic benefits of float therapy.

Potential drawbacks and considerations of float therapy include:

1.Claustrophobia: Individuals with claustrophobia may experience discomfort or anxiety in enclosed float tanks or pods. Open float pools might be a more suitable option for them.

2.Skin Sensitivities: Some individuals may experience skin irritation or allergies due to the Epsom salt solution. It is recommended to consult with a healthcare professional if you have any skin concerns.

3.Infection Control: It is important to ensure that float therapy centers maintain strict hygiene and sanitization practices to prevent the spread of bacteria or other pathogens in the water.

When considering float therapy, it is crucial to find a reputable float therapy center or practitioner. Here are some considerations:

1.Research and Reviews: Look for centers with positive reviews and check their online presence and reputation. Read testimonials or experiences of previous clients.

2.Cleanliness and Maintenance: Visit the center beforehand to assess the cleanliness and maintenance of the facilities, ensuring that they adhere to proper hygiene standards.

3.Qualified Staff: Inquire about the training and qualifications of the float therapy practitioners. They should be knowledgeable about the therapy and able to address any concerns or questions.

4.Safety Measures: Ensure that the center follows safety protocols and provides guidelines for hygiene, water maintenance, and client safety.

5.Communication: Engage in open communication with the center or practitioner, discussing any health concerns, allergies, or specific needs you may have.

It is advisable to consult with a healthcare professional before trying float therapy, especially if you have any underlying medical conditions or concerns.

In summary, float therapy involves immersing oneself in a float tank or pod filled with a saltwater solution, offering various potential benefits for relaxation, stress reduction, pain relief, improved sleep, and mental clarity. It works by creating a sensory-restricted environment that promotes relaxation and internal processing. Scientific theories, such as REST and neurochemical changes, support its therapeutic effects. When considering float therapy, it is important to be aware of potential drawbacks and ensure you find a reputable center or practitioner by conducting research, considering cleanliness and safety measures, and communicating your needs and concerns. Consulting with a healthcare professional is recommended, especially if you have any medical conditions.

hope that helps you if there is anthing else just ask :)

user: Have there been any randomized controlled trials of float therapy? If so, what did they find? Are there other types of relaxation therapy which have had randomized controlled trials?

assistant: There have been several randomised controlled trials of float therapy that have proven to show mixed results. Many trials also have a low number of participants, meaning that their results may not be accurately representative of a wider population. Here are some examples of trials that have employed float therapy.


1. > Loose LF, Manuel J, Karst M, Schmidt LK, Beissner F. Flotation Restricted Environmental Stimulation Therapy for Chronic Pain: A Randomized Clinical Trial. JAMA Netw Open. 2021;4(5):e219627. Published 2021 May 3. doi:10.1001/jamanetworkopen.2021.9627

This trial found that float therapy had a positive short-term impact on patients, but did not appear to have any meaningful long-term impacts. The short term group reported significant improvements in pain intensity, relaxation, anxiety and pain areas and also the widespreadness of the pain. However, the authors note that similar changes were observed in the placebo group.

It should also be noted that this trial had a total of 99 patients with 81% of the participants being women, introducing a bias into the study. Some of the specified improvements during the study are rather vague was well, as the self-reported measurement of 'rexalation' varies with each participant.

2. > Kjellgren A, Westman J. Beneficial effects of treatment with sensory isolation in flotation-tank as a preventive health-care intervention - a randomized controlled pilot trial. BMC Complement Altern Med. 2014;14:417. Published 2014 Oct 25. doi:10.1186/1472-6882-14-417

This trial found that float therapy had a significant improvement on stress, depression, anxiety and worst pain compared to the control group. They also indicated that there is a significant correlation between mindfulness in daily life and a degree of 'altered state of consciousness' during the relaxation in the floating tank. They conclude that 'flotation-REST' has beneficial effects on relatively healthy participants.

It should be noted that potential biases may have formulated during this study as the participants were selected through advertisements through intranet correspondence of companies relevant in the floatation therapy business, company magazine and emails, offering all employees an opportunity to participate in the healthcare program. Naturally, these employees would have an incentive to provide a positive result to the researchers during the study, compared to a more randomised subset of the population. Data from the study was also managed by the floatation centre, which may have had a finanical incentive being a provider of flotation therapy, to report more positive results.

As with the previous study, it is difficult to accurately measure stress of anxiety in a way that can be consistent throughout studies, as each study has their own interpration on the measurement of stress, as well as the participants. The mention of 'altered state of consciousness' as the authors state, is also rather vague and may not accurately reflect the readers interpreation.

3. > Garland MM, Wilson R, Thompson WK, et al. A randomized controlled safety and feasibility trial of floatation-rest in anxious and depressed individuals. medRxiv. January 1, 2023. Accessed June 9, 2023. https://www.medrxiv.org/content/10.1101/2023.05.27.23290633v1.

This trial found that in anxious and depressed individuals, floatation therapy was safe, well-tolerated and associated with acute anxiolysis (inhibition of anxiety). However, the authors note that there is not yet sufficient evidence of the feasability of the method as a repeated intervention. They state that further research is warranted with larger randomized control trials, to evaluate markers of clinical efficacy. 

These are just a few examples of randomised controlled trials of floatation therapy, which have shown to have mixed results as you can see in the samples that I have provided above.
Whilst there does appear to be certain positive short-term benefits with floatation therapy, there is little evidence to the fact of flotation therapy being a positive long-term intervention for patients with depressive and anxiety disorders.

It is important that you weigh the results of these trials and understand the goals of each studies, so that you can make your own decision during your journey of flotation therapy.

If you want to know more about flotation therapy, please do not hesitate to ask.
