Sleep science is a field of study that explores the biological mechanisms of sleep, its patterns, and its impact on our overall health and well-being. It investigates how our waking state activities influence when we fall asleep, how quickly we fall asleep, whether we stay asleep, and how we feel when we wake up the next day. Sleep science also delves into the stages of sleep, sleep spindles, melatonin, and dreaming. It's a fascinating area of research because it helps us understand the importance of sleep in resetting our ability to be focused, alert, and emotionally stable during our wakeful periods. It also provides us with tools to improve our sleep quality and efficiency.
