Another consequence of kids’ smaller size: They cool more rapidly in cold temperatures, especially in water below 50 degrees Fahrenheit. “The risks are much higher than adults who have double ...

The tank is filled with 10 inches (25 cm) of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.25–1.26, enabling a person to float freely with their face above the water. In order to reduce thermal sensations, the water in the float tank is maintained at approximately skin temperature, around 35 ...
