Good sleep is critical to our innate physiological repair processes, while poor sleep triggers a cascade of negative downstream consequences, from insulin resistance to cognitive decline, as well as mental health issues.

Study after study has found powerful associations between insufficient sleep and adverse health outcomes ranging from the common cold to cardiovascular disease.

But as important as sleep is for the physical body, it may even be more so for the brain. Good sleep—in terms of both amount and quality—is critical to our cognitive function, our memory, and even our emotional equilibrium.

Below is a collection of past articles, audio clips, and podcasts discussing the science of sleep and how sleep can be a powerful longevity tool. If you are new to this content, I would strongly recommend listening to our 7-part series with sleep expert Matthew Walker, where we discuss everything you could possibly want to know about sleep, the affects of sleep on your health, and how to improve it.
