Sensory deprivation tanks were first invented in the 1950s by Dr. Jay Shurley and Dr. John Lilly. Their main goal was to examine human consciousness and the brain’s reaction to a complete lack of external stimuli.

It was thought that being without any sensory input such as sound or light would cause a person to fall into a state of unconsciousness, but that wasn’t the case. The test subjects maintained complete awareness.

Today, flotation therapy tanks are thought to have a positive effect on health conditions that are driven by stress, such as high blood pressure, tension headaches, and muscle pain, as well as mental disorders such as depression and anxiety. Read on to find out more about float therapy and its benefits.

What Are the Benefits of Float Therapy?

While float therapy began as an experiment to study human consciousness, it is now used as a form of physical and mental health therapy. Current research has shown that there are several benefits of float therapy on overall health.

Physical Benefits of Float Therapy

Studies have found that physical health can be positively affected by float therapy. It can lead to an improvement in:  

Chronic pain found in conditions such as rheumatoid arthritis Tension headaches Muscle tension Whiplash symptoms such as a stiff neck Immune function Cardiovascular health, which involves the health of the heart, veins, and blood vessels High blood pressure Recovery after sports injuries Brain function Fatigue Insomnia and other sleep disturbances

Mental Health Benefits of Float Therapy

In addition to the many physical health benefits of float therapy, there are many mental health benefits as well. Float therapy has been shown to reduce the symptoms of:

Depression Anxiety High stress levels Fear-driven phobias Substance abuse disorder

Risks

Although many of the studies around the effects of float therapy reveal little to no adverse effects, there have been some reports of people experiencing hallucinations while in the tank that could be disturbing in nature.

What to Expect

Experiencing float therapy can be both scary and exciting, depending on the person. While there are benefits, people will respond to it differently. When you arrive, you can expect to remove all clothing and jewelry and shower prior to entering the tank.

Additionally, being under the influence of drugs or alcohol can also increase the risk of drowning. And those who are pregnant may want to check with their OB-GYN before trying float therapy.

Once in the tank, you will close the door or lid, depending on the type. The saltwater should allow your body to float effortlessly so you can lie back comfortably without sinking. You’ll then float in the tank for up to an hour before exiting, showering off the salt, and getting dressed. All or most external stimuli such as music or light will be taken away during the float session.

Summary

Flotation therapy, although first designed to explore the depths of human consciousness, is now a viable management option for many health conditions such as anxiety, depression, chronic pain, and tension headaches. The tanks have been studied for their benefits and risks, and although some people should avoid them, there seem to be few adverse effects reported in the literature.

Float therapy has been shown to be incredibly beneficial for many people. That being said, the experience could be daunting for others due to the confined space. Whether you have tried float therapy, are thinking about it, or couldn’t dare yourself to do it, there is no denying that people with various health conditions could benefit from regular float therapy sessions.
