Sensory Deprivation Tank – Explanation

Sensory Deprivation Tank is relaxation therapy. It is known to help persons suffering from chronic stress, work-related muscle pains, gastric upsets and burnout. It may also be used for insomnia or other sleeping complaints.

Sensory deprivation, or restricted ecological stimulation therapy (REST), is a technique by which sensory input is minimized. REST is typically led in a float tank, in which the person is suspended in a solution of open water and Epsom salt without sound or light. This practice encourages an intense level of relaxation.

This condition is known to evoke a reduction reflex (RR). This reflex is the opposite of the “flight or fright” response when dealing with stress. RR directly affects the parasympathetic system and causes many positive effects on the body systems.

Fall Asleep in a Sensory Deprivation Tank

No. The nastiest that can happen is getting woken up by a bit of saltwater in the eyes. Some persons fall asleep, but the water is so buoyant that they stay afloat. Using the shower afterwards is also suggested to remove the coating of Epsom salt that is left on the skin and hair.

This all occurs whether an individual is awake in the tank. A times fluctuating offers similar physical and mental benefits to a six-hour sleep in a bed.

A Power of Float Sensory Deprivation Tank

An hour in a float tank can assist by a power nap that greeneries a separate refreshed and energized—an hour of floating equals as much as eight hours of regular sleep.

The sensory deprivation tank may also help ease muscle tensions and mental worries. This may be due to the complete cessation of stimuli of sound and sight. Also, the abolition of gravity on the body allows the muscles and joints to announce tension and also get rid of soreness. For this motive, people suffering from musculoskeletal and rheumatic conditions greatly benefit from initiation REST.

An Unusual Death Involving a Sensory Deprivation tank

Deaths involving sensory deprivation tanks are sporadic. We describe a unique case in which a previously healthy 50-year-old woman died while floating in a sensory deprivation tank at her residence. Autopsy failed to reveal definitive anatomical abnormalities pointing to the cause of death.

A thorough scene investigation, complete medicolegal autopsy to include toxicological analyses, and comprehensive research into the equipment at the scene conduct. Blood toxicologic studies were significant for the presence of ethanol (0.27%) and also a mixture of over-the-counter sedating medications and prescription drugs. The cause of death a line as acute diverse drug and ethanol venomousness combined with probable conservation hyperthermia; manner was an accident. This case report will help the forensic community understand the intended use of flotation tanks and also possible risks associated with improper use.

Effects and Benefits

There is an indication that sensory deprivation affects the brain. Its effects may vary among persons, but some of the described benefits are:

Possible Boost to Originality

A 2014 study compared the publicity claims of sensory lack centres with clinical explore. The authors found that several studies maintained that a person might experience a boost in originality. However, they advised that the effects are not general and noted that centres’ claims remain often overstated.

Possible Improved Physical Performance

Sensory deprivation tanks may benefit contestants and people who train intensively for competitions. According to obtainable explore, the belongings may be both physical and rational.

For example, a small 2016 study create that floating therapy better physical and mental recovery after training sessions. However, the education also notes that the results are initial and that additional research is essential.

Possible Anxiety Treatment

Sensory deprivation tanks may help decrease symptoms in people with anxiety. Several recent studies have looked at REST’s positive effects on pressure.

The researchers behind a small concluded that sensory deprivation therapy could help improve the symptoms of anxiety and depression. Still, they indicated that more extensive studies are essential to confirm the effects of sensory lack on these circumstances.

Possible Pain Reduction

The extra optimistic effect of REST may be the alleviation of pain. Numerous studies have revealed that sensory deprivation can reduce the amount of pain that a person experience.


Researchers have reported limited risks when the members in their investigation have been in relatively good health. However, some people may live within the tank, disturbing. Both subjective and research evidence suggest that some people will experience psychosis-like visions. In a small 2015 study, researchers divided members into two groups based on how prone they were to hallucinations. The researchers identified as being more likely to hallucinate had more hallucinations than those in the other group. If a being does experience hallucinations, these should stop once they leave the tank.

Spending time in a dark, quiet, enclosed planetary is a scary experience for some people. If this is the circumstance, a person may not appreciate their time in the tank. Though a person could strictly drown in the flotation tank, this accident is very rare. The best method to avoid it is to prevent incoming a high or otherwise intoxicated tank.

Researchers need to carry out more educations to recognize the belongings that sensual deprivation reservoirs may have on people. Though, most people with a good health status must tolerate the experience with minimal risk.

Does it Work? 

Research supports the claim that physical deprivation tanks do work for some people. The well-known positive effects relate to decreasing anxiety, managing pain, and helping athletes improve from strenuous training. The knowledge may also help improve a person’s focus.

However, people should approach sensory deficiency tanks with caution. If a corporation or person selling sessions or tanks makes claims that seem too good to be true, they probably are. Sensual deprivation tanks are not a cure for any disorder. A being should not use them as an extra for methodically supported treatment.


Sensory deprivation tanks may offer some relief from nervousness and pain. The tanks are relatively safe, but they can produce side effects insure people. These effects may include hallucinations, particularly in individuals already prone to them. Most people should involvement no adverse effects and may find that they can relax during their REST session.
