Who Should Not Use a Float Tank?

Float therapy, with its serene promise of stress relief and mental clarity, has captured the attention of wellness enthusiasts far and wide. At the heart of this experience lies the float tank, also known as a sensory deprivation tank, offering a unique environment for deep relaxation. However, float therapy isn’t suitable for everyone despite the many benefits. So, who should not use a float tank? This comprehensive guide aims to clarify who should think twice before stepping into a float tank and the considerations that come with it.

Sensory deprivation tank first-timers: Important considerations

Understanding the process and what to expect can significantly enhance the experience for newcomers to float therapy. It’s essential to be aware of potential interactions with medications and to ensure personal mobility to enter and exit the float tank safely. Discuss any medical concerns with a healthcare professional to understand any adverse effects your medications might have on your float session and whether float therapy is suitable for your wellness journey.


For some, the enclosed space of a float tank might make them feel claustrophobic and even trigger panic attacks. That’s why we offer larger float rooms alongside our standard float pods. If you are slightly claustrophobic but still want to try floatation therapy, our Dreamweaver Room or Couples Room are fantastic options for enhancing your well-being in a claustrophobia-friendly environment.

Epilepsy or severe neurological conditions

People who should not use a float tank include individuals with severe mental health conditions such as psychosis, schizophrenia or seizure disorders. The environment of sensory deprivation tanks can also pose risks for individuals with epilepsy, particularly if not well-controlled.

Floating in your first trimester of pregnancy 

Many pregnant women find float tank therapy beneficial for alleviating physical discomfort and fostering a deep connection with their babies. However, it’s crucial to seek medical advice before floatation therapy, especially if experiencing any pregnancy-related complications. While studies have shown that it’s safe to float throughout the whole nine months of your pregnancy, we recommend floating after your first trimester to be safe.

Open wounds

The high salt concentration in float tanks can irritate and prevent the healing of open wounds. It’s advisable to wait until wounds, skin irritations, piercings, and tattoos fully heal before floating.

Under the influence of alcohol and drugs

It’s imperative to approach float therapy with a clear mind and body. Those under the influence of alcohol or drugs should avoid float tanks. These substances can impair judgment, reduce the ability to maintain a safe floating position and potentially lead to adverse experiences.

Undergoing chemotherapy or radiation therapy

Individuals undergoing cancer treatment, such as chemotherapy or radiation therapy, should consult their healthcare provider before using a float tank. Due to its detoxifying properties, float therapy may counteract the intended effects of your medical treatment. We recommend waiting at least 4-6 weeks after your last treatment session before using float tanks to ensure optimal results from your medical care.

Newly dyed hair and new hair extensions

The high content of Epsom salts and hydrogen peroxide in the float tank water can affect the colour and condition of newly dyed hair. We recommend waiting at least a week (or three thorough washes) before you use a float tank. If you have just invested in extensions, we suggest asking your hair stylist if it’s safe to float.

Spinal instability or spinal conditions

Those with spinal conditions or instability should seek advice from a medical professional to determine whether float therapy could benefit or have harmful effects on their spinal condition.

Kidney diseases

People with kidney disease should exercise caution when considering float therapy. Weakened kidneys may struggle to process the increased magnesium absorption and rapid detoxification during float tank therapy, potentially leading to stress on the organs. It is crucial to consult a healthcare professional before proceeding, as the severity of the condition can vary greatly.

Infectious diseases

While the salt solution in floatation tanks creates an environment that is generally inhospitable to bacteria and viruses, those with contagious diseases should abstain from floating to prevent the spreading of infection.

Ear infections

Float therapy involves immersing oneself in a tank filled with Epsom salt water, which can enter the ear canal and potentially irritate existing infections. If you’re prone to ear infections or have one, consider using waterproof earplugs and consulting a healthcare provider before floating to prevent complications.
