Hi, I apologize for the inconvenience, I heard Andrew saying something in an episode of the podcast that is contrary to what is found on the internet, the topic is the glymphatic system, Andrew says in the episode that raising the bottom of the bed improves the activity of the glymphatic system, while online I only find the opposite said, to raise the top of the bed, what is the right thing? Thank you a lot 🙏


has actually highlighted the benefits of elevating the feet during sleep to improve glymphatic system activity. He describes the glymphatic system as akin to a clearance system in the brain, crucial for removing neural debris particularly during slow-wave sleep. According to the data refers to, elevating the feet or lying on one side can enhance the clearance through the glymphatic system, as the system is influenced by physical fluid dynamics that are optimized in these positions. The elevation of feet helps to increase the clearance of debris due to the mechanics of the glymphatic system. Therefore, based on what describes in the podcast, elevating the bottom of the bed where the feet are located would be the correct method to enhance glymphatic activity during sleep 1 2 3.
