Sleep, Health, and Fitness
The Stronger By Science Podcast
Circadian Clocks and Chronobiology
The sleep-wake cycle, of course, is going to be something that is very directly impacted with some circadian rhythmicity. Core body temperature does tend to have some fluctuation throughout the day in a repeatable cycle and even immune system activity as well. So there are a number of these different biological processes that are intrinsically linked to circadian rhythms.
In today’s episode, Eric Trexler discusses the relationships between sleep, health, and fitness. First, he discusses how sleep impairments can negatively impact health-related outcomes and impede progress toward a variety of fitness-related goals. After that, he describes a number of practical strategies to get better sleep and to mitigate the negative impacts of insufficient sleep.
