Dr Andrew Huberman - The New Science Of Longevity, Resilience & Breaking Bad Habits

Delay morning caffeine to prevent afternoon crash

Huberman explains the adenosine system and why delaying caffeine for 60-90 minutes after waking helps clear residual adenosine and prevents the afternoon energy crash.

"The drug, the most commonly used drug, the drug we're using now and that we're on right now, caffeine, which is consumed by it's estimated more than 90% of the world's adult population."

Non-sleep deep rest clears residual adenosine

Huberman describes how NSDR (Yoga Nidra) is a zero-cost tool with growing science that can clear residual adenosine upon waking, serving as a powerful complement to delayed caffeine.

"If you don't block those adenosine receptors, there's still clearance of adenosine occurring in part because you're sort of still asleep. Wow. The other thing that works remarkably well to clear out residual adenosine is upon waking, if you don't feel rested enough to do something I've talked also a lot about, which is another one of these zero-cost tools that has a growing amount of impressive science to support it, which is non-sleep deep rest or NSDR, also called Yoga Nidra."

Morning sunlight for alertness and adenosine clearance

Huberman recommends getting sunlight in your eyes as soon as possible after waking to enhance alertness and help clear residual adenosine from the system.

"Typically, people get out of bed, they might look at their phone. As you know, I encourage them to go find sunlight if the sun isn't out, to turn on bright lights and then get outside and get sunlight in their eyes as soon as they can."

Cold plunge temperature and practice details

Huberman shares his personal cold plunge protocol at 45-48 degrees Fahrenheit and discusses the practice with humor.

"typically and 4 p.m., somewhere in there. For me, the trough in my natural energy levels in the afternoon is consistently between 2 and 3 p.m., regardless of how well I slept the night before. Many people also find a consistently placed trough in their energy, independent of all this. Okay, so what can we do? Some years back, I started suggesting that people consider, if they have an afternoon crash in energy, that they delay their morning caffeine intake for nine."

Sleep duration and adenosine clearance fundamentals

Huberman explains that most people do not sleep enough to fully clear adenosine, leading to residual sleepiness upon waking, and discusses six to eight hours as the typical need for most adults.

"However, most people don't sleep until they naturally wake up feeling refreshed. Most people are using an alarm clock. Most people are not going to sleep as early as they need to, or sleeping as late as they need to, or both."
