Floating and Your Brain Part II: Left Brain vs Right Brain

A human brain is divided into two distinct hemispheres. Each hemisphere is responsible for carrying out different functions that are important to keeping the human body alive and healthy.


The left hemisphere is the logical side. It pays attention to detail and processes analytical information. Reason and logic are the products of left brain functions The right hemisphere, on the other hand, operates by pattern recognition. It absorbs large amounts of information and stimulates emotional or creative responses. This makes the right hemisphere the driving force behind creative expression such as painting, writing and singing.

How does this relate to floating in an isolation tank? A simple answer is that flotation opens the door to the right hemisphere of a floater’s brain. It allows the right brain to become dominant over the left brain – even for a short time.


A floater experiences increased right brain function inside an isolation tank. One reason is that the external distractions that enable the left brain to dominate are shut off during a floating session. When our bodies are able to relax, it also frees our mind.

The clutter of thoughts reduces to a trickle and the negative energy dissipates. Our natural creative side emerges and we are able to see the world in a brand new light.

There’s no sense suppressing your right brain. Letting your creative energies roam free can let you find inspiration and meaning on days when the world seems overwhelming. It offers another reason why floating is good for you.
