Sensory Deprivation Tank
In 1954, a Neurophysiologist invented and conducted a study of the self-meditation technique using a Self-Deprivation Tank. The Neurophysiologist is Dr. John Lilly of the National Institute of Mental Health Located in Bethesda, Maryland. Later on, he referred the technique as Restricted Environmental Stimulation Technique or the abbreviated name of REST. In his study, he first tried the technique in a student. Students are floating in a Sensory Deprivation Tan, where their visions, hearing and everything is being blocked. They only float in a water tank that is filled with water that has a dissolved Epson salt. Also, the water has a temperature that suits and is good for the skin. After almost a 2 hours session testing, the students responded that he physically and mentally got better. So, Dr. Lilly concluded that the REST is really effective in meditation, concentration and making a person physically and mentally better.
A Sensory Deprivation Tanks or Sometimes referred to as Isolation Tank, is a machine tank that has a soundproof environment, meaning sounds outside the Tank is being blocked, or you cannot hear anything. The Sensory Deprivation Tank has lightening inside, and visions outside are blocked. The person inside will see nothing but the lights that surround the machine. The Machine tank was specifically designed for a person to lay down very comfortably while floating in the water. It has also a very easy access to the entrance and exit points. The water inside approximately filled with 10 inches water with a dissolved solution of Epson salt. Epson salt, also known as magnesium sulfate, is very important for floating because the water content of the tank has 30% solution of Epson salt that makes the person inside weightless so that they will not sink in the water while meditating. Inside the machine, a person can never be disturbed while meditating because everything is blocked from visions outside, noises and everything.
The temperature inside is typically maintained for the safety of the person, so the air and the waters’ temperature are at constant. The temperature makes it more relaxing and appealing for a meditation. While a person is floating, their body gets more relaxed, their blood flows properly, homeostasis is being achieved by the body, and the neurochemical imbalances are being resolved that is caused by stressful things. The main goal of Restricted Environmental Stimulation Technique (REST) is to reduce the stress and tension levels of a person and to physically and mentally help them. A deep level of relaxation and meditation, provided by the Sensory Deprivation Tank, has a high recommendation by many experts. Furthermore, Restricted Environmental Stimulation Technique (REST) that can be provided by Sensory Deprivation Tank, can make your nervous system works better, your cardiovascular system will be relaxed as well as your blood circulation.
Mental Health is very important as Physical Health. You should provide yourself a meditation to relax and to get rid of the stressful things that make you very stressed that might lead to anxieties.
