We’ve all experienced brain fog and the drowsiness that comes with getting too little sleep. But what exactly happens in our brain during sleep that prepares us for another day in the morning? To understand how the brain disposes of so-called “metabolic waste”, teams of researchers are working on a study with $2.8 million funding from the U.S. Army who is looking to combat sleep disorders among the military. The scientists’ ultimate aim is to develop a “sleeping cap” that would analyze how fluids within the brain may be flushing out toxic, memory-impairing proteins while you sleep. The sleeping cap that the researchers aim to create would be lightweight and portable, with the ability to both track and stimulate the flow of the cerebrospinal fluid. In this way, the researchers hope to be able to treat sleeping disorders as they happen. all experienced brain fog and the drowsiness that comes with getting too little sleep.
