In today’s episode, Matt shines a spotlight on the science behind napping and explores the optimal nap duration for various cognitive benefits. He starts by introducing the concept of napping and its benefits for the brain and body, and then discusses sleep inertia, the groggy feeling upon awakening from a nap, and its potential impact on brain performance.

Matt walks through the dose-response curve of naps, starting with ultra-short power naps of five minutes or less, which show no evidence of sleep inertia but offer minimal cognitive benefits. He then progresses to 10-minute naps, which demonstrate improvements in alertness and sustained attention. The benefits continue to increase with 15-minute and 20-minute naps, enhancing alertness, concentration, and problem-solving abilities. However, sleep inertia becomes more noticeable with longer naps, such as 30-minute to 60-minute durations, although the cognitive benefits are more significant and long-lasting.

Lastly, Matt shares the origin of the term "power nap" and how it emerged from research conducted by Dr. David Dinges and Dr. Mark Rosekind for the Federal Aviation Authority (FAA) to combat sleep deprivation among pilots. They discovered the benefits of preemptive napping to build resilience against subsequent sleep deprivation during long-haul flights, leading to the adoption of the term "power nap" by the FAA.

Listen in today to gain valuable insights into the art and skill of napping, emphasizing the importance of finding the right nap duration to balance cognitive benefits and sleep inertia. #TheNapPodcast #NapScience #PowerNap
