Hello! I think we have to parse this apart a bit. There have been some recent studies that show CSF is related to movement of metabolites in the brain, however these findings are very new. So if you theoretically wanted to induce more CSF flow while awake, I think this would be possible, but you would have to use a pretty obnoxious stimulus or use a deep breathing exercise - e.g meditation But because we don’t know the complete reason of why we have changes in CSF flow when people are asleep, maybe there are other mechanisms going on that are acting simultaneously with sleep — e.g large fluctuations in blood flow may be necessary to induce CSF flow
