Lina S Great question. We go through all the reasoning for hydration movement concepts in our online hydration Course if you would like to go into more specifics (I've popped course link below). But in brief, think of twisting like wringing out a sponge - it squeezes out the old fluid and the cells/tissues then respond by filling up with fresh fluids. Thank you for taking the class and glad you enjoyed it. Here is the COURSE LINK that will take you into more about hydration if you are keen 😊
