The regeneration of these neurotransmitters is essential in a healthy brain that is capable of learning, remembering, performing and problem solving. Sleep spindles occur during rapid eye movement (REM) sleep, which takes place toward the end of the night (between the sixth and eighth hours of sleep, according to the APA) and is crucial to replenishing neurotransmitters in the brain. The more sleep spindles someone experiences, the better defense they have against intrusive, outside noise.Īccording to research published in Cell Press, the more sleep spindles someone experiences, the better defense they have against intrusive, outside noise, which is why people who rely on fans to sleep often have a lower production of sleep spindles in their brains. ![]() So what causes fan enthusiasts to typically be categorized as light sleepers, while there are others who could sleep through road traffic, construction work, or perhaps a category one hurricane?
