Why isolation tank ventilation matters

Comfort is essential to enjoying time spent in an isolation tank. You can’t feel comfortable if you don’t feel safe. One important safety element in floating is ventilation.

If you build your own isolation tank, one thing you need to do is build a tank that has proper ventilation. You also need to make sure the floatation tank room ventilation is at safe levels so you don’t risk overheating, dehydration or other possible dangers to your body.


Some people worry about the water cooling too rapidly with vents on the isolation tank. When you build your own tank, you can insulate the tank or use heaters under or around the tank to keep the water at a fairly constant temperature. But it is important to remember ventilation is always required.

Sensory Deprivation / Isolation Tank

The whole room needs to ventilation to exchange warm wet air with dry cool air. It lets the floater have a constant supply of fresh air.

Exposure to stale air can be dangerous over a prolonged period of time. Human lungs expel carbon dioxide during breathing. Carbon dioxide can be suffocating in concentrated doses. Allowing outside air to circulate inside the tank allows fresh oxygen to enter.

Oxygen is important to the health of your brain. And since brain activity powers the entire floating experience, having plenty of fresh air to breathe enhances floating so it can be enjoyed at the level it should be enjoyed.

Breathe deep and enjoy the atmosphere during your next floating session. The fresh air is good for your body and your mind.
