Float therapy, often referred to as sensory deprivation or isolation tank therapy, has gained considerable attention in recent years as an innovative approach to managing anxiety and stress. The practice involves floating in a tank filled with warm water and Epsom salt, where sensory inputs such as sound, light, and touch are minimised. But how effective is float therapy for anxiety? This article explores the scientific evidence supporting float therapy, how it impacts the brain, and how it compares to other anxiety treatments. Let's get started!
Sensory deprivation tanks, also known as isolation tanks, were developed in the 1950s by neuropsychiatrist John C. Lilly as a way to explore the effects of limited sensory input on the brain. These tanks are designed to eliminate external stimuli, creating an environment where users can experience profound relaxation and mental clarity.
Typically, a float tank is filled with shallow water and a high concentration of Epsom salt, which allows the body to float effortlessly. The water is heated to skin temperature, further enhancing the sensation of weightlessness. The environment inside the tank is lightless and soundproof (optional), making it easier to disconnect from the outside world and enter a deeply relaxed state.
During a float therapy session, individuals enter the tank and lay back in the water, allowing the body to float naturally. This zero-gravity experience is designed to calm the nervous system by reducing sensory input. The reduction in external stimuli helps to shift the body into a state of deep relaxation, often described as similar to meditation but with fewer distractions.
As the body becomes weightless, the muscles and joints relax, and the mind can slow down. This state of rest can be particularly beneficial for those suffering from anxiety, as it allows the brain to shift from the “fight or flight” mode to a more balanced state.
Float therapy’s impact on anxiety is rooted in its ability to influence the brain’s stress response. Research has shown that during a float session, the body’s sympathetic nervous system (responsible for the "fight or flight" response) becomes less active, while the parasympathetic nervous system (which promotes "rest and digest") becomes more dominant. This shift can lead to a decrease in heart rate, blood pressure, and cortisol levels, all of which are indicators of reduced stress.
Brain wave patterns also change during float therapy. Studies have observed an increase in theta and alpha waves, which are associated with deep relaxation and mental clarity. These brain wave patterns are often seen in meditation and can contribute to the overall calming effect of float therapy.
The effectiveness of float therapy for anxiety has been supported by various clinical studies. A 2018 study involving individuals with anxiety-related disorders found that float therapy significantly reduced stress and anxiety levels compared to other relaxation techniques. Participants in this study reported not only immediate relief from anxiety but also long-term improvements in their overall mental health.
Another study conducted in 2021 focused on individuals with generalised anxiety disorder (GAD) who underwent multiple float sessions over several weeks. The findings revealed a significant reduction in anxiety symptoms, with effects lasting up to six months after the study. These results suggest that float therapy can be a valuable tool for managing chronic anxiety.
When comparing float therapy to more conventional anxiety treatments, such as medication and cognitive-behavioural therapy (CBT), it's important to consider both the similarities and differences. While traditional treatments often focus on altering thought patterns or chemical balances in the brain, float therapy provides a physical environment that promotes relaxation and reduces sensory input, which can complement these treatments.
For instance, while medications like SSRIs work by regulating neurotransmitters to manage anxiety, float therapy allows the body to naturally lower stress hormones like cortisol. Cognitive-behavioural therapy, on the other hand, helps individuals identify and change negative thought patterns, whereas float therapy provides a space for the mind to rest and reset, potentially enhancing the effectiveness of CBT.
Many practitioners and users suggest that float therapy is most effective when used alongside other anxiety management techniques. For example, combining float therapy with mindfulness practices or meditation can amplify the benefits of both. During a float session, the quiet, distraction-free environment can make it easier to practise mindfulness or deep breathing techniques, potentially leading to more profound and lasting relaxation.
Moreover, some studies indicate that individuals who integrate float therapy into a broader wellness routine—such as regular exercise, balanced nutrition, and therapy—may experience more significant reductions in anxiety than those who rely on a single method.
While float therapy is generally safe for most people, certain conditions may make it unsuitable for some. Individuals with claustrophobia, severe psychiatric conditions, or those who experience dissociation should consult with a healthcare provider before trying float therapy.
Additionally, those with breathing difficulties, allergies to Epsom salt, or skin conditions may also want to avoid float therapy or seek medical advice prior to a session. It’s important to approach float therapy with realistic expectations and a clear understanding of what the experience entails.
For first-time users, it’s crucial to enter a float session with an open mind and no strict demands. The key to benefiting from float therapy lies in allowing yourself to relax and adapt to the environment. Some users may not achieve deep relaxation immediately, but with practice, the mind and body can learn to fully embrace the experience.
Preparing for a float session by practising deep breathing or setting a simple intention can also enhance the benefits. Remember, the goal is to relax and reset, so give yourself permission to let go of external worries.
Float therapy presents a promising option for those looking to manage anxiety in a natural and holistic way. The practice has been shown to reduce stress, lower anxiety levels, and improve overall mental well-being. While it may not be suitable for everyone, the benefits for those who do respond positively can be profound and long-lasting.
If you’re interested in exploring flotation therapy as part of your anxiety management plan, consider scheduling a session at Float Co.. We provide a premium float experience designed for maximum comfort and therapeutic benefit.
Each of our pods contains around 500kg of Epsom salt, a naturally occurring compound of magnesium and sulfate, creating a safe and buoyant environment that enhances relaxation and offers anti-inflammatory benefits.
Whether you prefer a solo session or want to share the experience, our spacious pods are equipped with easy-to-use controls, allowing you to tailor the experience to your comfort level. We can guide you through the process and help you get the most out of your float experience.
For the best results, Float Co. recommends floating on a weekly basis, especially for those looking to manage anxiety. Regular sessions can enhance your physical, mental, and emotional health. However, the ideal frequency can vary based on individual needs and schedules. Some may benefit from more frequent sessions, while others might find relief with just one or two floats per month. It’s advisable to start with a few close-together sessions and then adjust based on how your body and mind respond.
Float therapy can be a complementary approach to managing anxiety, offering significant relaxation and stress relief. However, it should not replace prescribed medication or other treatments without consulting your healthcare provider. At Float Co., we encourage clients to integrate floating into a broader wellness plan, which may include therapy, medication, and other self-care practices.
At Float Co., your first session will begin with a 30-minute introduction from our Float Guide, who will walk you through the process and answer any questions. You'll then enter your private room, where you can shower before stepping into the pod. The session itself is 60 minutes long, during which you will float in a warm, soundproof pod filled with Epsom salt. First-timers may feel disoriented initially, but most experience a deep sense of calm and relaxation by the end. After your float, you’re welcome to enjoy a cup of tea in our relaxation area to prolong the post-float glow.
Float therapy is generally safe with minimal side effects. Some users may experience mild itching or dry mouth due to the saltwater. At Float Co., we provide all necessary amenities, including earplugs and lotions, to minimise discomfort. While rare, individuals with pre-existing psychiatric conditions might experience heightened anxiety or dissociation during the session. If you have any concerns, our staff is available to discuss them before you float.
The duration of float therapy benefits can vary. Some clients at Float Co. report feeling immediate relief that lasts for several days, while others notice longer-term improvements after regular sessions. The calming effects on the nervous system and the overall sense of well-being often extend beyond the session, contributing to ongoing stress and anxiety management.
