The Ups and Downs of Floating: Why Some Experience Nausea

Flotation therapy, also known as sensory deprivation or REST (Restricted Environmental Stimulation Therapy), has gained popularity due to its numerous relaxation benefits. However, while many floaters emerge feeling refreshed and rejuvenated, a small subset experiences an unexpected side effect: nausea. This blog post delves into the potential reasons behind this phenomenon, exploring the interplay between our senses, physiology, and the unique environment of the float tank.

While robust, large-scale studies specifically focusing on nausea during or after floating are limited, we can draw insights from research on motion sickness, anxiety responses to novel environments, and the physiological effects of deep relaxation to gain a deeper understanding of this phenomenon.

1. The Confused Balance System (Vestibular System):

One of the primary culprits behind nausea in various situations is the vestibular system, the intricate network within our inner ear responsible for balance and spatial orientation. In a float cabin, the absence of visual and tactile cues can sometimes lead to sensory disorientation or a mismatch between the senses. Your body senses stillness, but your brain, accustomed to constant sensory input regarding movement and gravity, might become slightly disoriented. This sensory conflict can trigger symptoms akin to motion sickness.

2. The Detoxification Theory (Anecdotal Evidence):

While not scientifically proven with specific studies in the context of floating, some proponents suggest that deep relaxation can facilitate the release of toxins stored in the body. They theorize that these circulating toxins could potentially lead to feelings of nausea as the body attempts to process them. However, this remains largely anecdotal, and scientific evidence directly linking floating-induced relaxation to significant toxin release causing nausea is lacking.

3. Anxiety and the Novel Environment:

For some individuals, the enclosed space and the lack of external stimuli in a float tank can paradoxically induce anxiety or a feeling of claustrophobia, especially during their initial sessions. Anxiety is a well-known trigger for nausea.

4. Blood Sugar Fluctuations and Dehydration:

Floating can be surprisingly demanding on the body as it works to regulate temperature and maintain homeostasis. Floating on an empty stomach can lead to low blood sugar, a common cause of nausea. Similarly, even mild dehydration can exacerbate feelings of unease and nausea.

5. Overstimulation Upon Exit:

After a period of sensory deprivation, the sudden reintroduction of bright lights, sounds, and the feeling of gravity can sometimes overwhelm the nervous system. This sensory overload can, in some cases, manifest as nausea.

Minimizing the Risk of Nausea:

While nausea during or after floating is generally uncommon, temporary, and not a cause for serious concern, there are steps individuals and float centers can take to minimize the risk:

• Stay Hydrated: Drink plenty of water before and after your float.

• Avoid Floating on an Empty Stomach: Have a light, easily digestible meal a couple of hours before your session.

• Take Your Time Exiting: After your float, gradually re-acclimate to the environment. Sit up slowly and take a few moments before standing.

• Focus on Your Breath: If you start to feel uneasy during the float, focus on slow, deep breaths.

• Communicate: Let someone on the Red Lotus Float team know you feel nauseous.  We can provide ginger chews, tea, or water to help ease your discomfort.

Tips to Avoid Nausea in the Float

So, while most floaters experience deep relaxation and well-being, nausea can be an occasional and unwelcome side effect. As research into flotation therapy continues to evolve, we may gain even clearer insights into this phenomenon and develop more targeted strategies for prevention. In the meantime, open communication and mindful preparation can contribute to a more positive and nausea-free floating experience.
