SNP38: What is Quality Sleep?

Sleep is one of the most critical yet often overlooked components of health, performance, and overall well-being. Poor sleep quality or insufficient sleep can disrupt circadian rhythms, impair glucose metabolism, and alter hunger signals, leading to increased food intake, reduced insulin sensitivity, and other undesirable outcomes.

In this episode, we bring together expert discussions from some of the leading researchers in sleep science, to explore what defines high-quality sleep, the mechanisms behind sleep regulation, and the factors that influence sleep-wake cycles, from light exposure to psychological stress.
