NOTE

Caffeine's Hidden Costs: Sleep Disrupted

Caffeine can significantly affect sleep quality and duration, with a half-life of about five to six hours in the average adult, meaning substantial amounts may still be in the system during sleep hours. Consuming caffeine too late in the day can lead to difficulties falling asleep due to its stimulant properties, increase anxiety levels, and create a racing mind that hampers sleep onset. Additionally, caffeine contributes to sleep fragmentation, causing more frequent awakenings throughout the night and reducing overall sleep efficiency. Importantly, even if individuals believe they sleep well after consuming caffeine, they may still experience a reduction in deep sleep, which is often unnoticed but essential for restorative rest.

Episode notes

Brought to you by Athletic Greens all-in-one nutritional supplement, Pique premium pu’er tea crystals, and Shopify global commerce platform providing tools to start, grow, market, and manage a retail business.

Welcome to another episode of The Tim Ferriss Show, where it is usually my job to deconstruct world-class performers to tease out the routines, habits, et cetera that you can apply to your own life.

This episode is something different. It’s an experimental format that I’m super excited about, and it’s back by popular demand.

This is an episode that scratches an itch I’ve had for years. I am not always able to listen to every great podcast episode out there, even when they are by some of my closest friends. The answer to my predicament was to ask them to send me a top segment from their podcast that I could listen to and—more importantly—also share with you, my dear listeners.

My team edited them together, and here we are! This episode is a compilation of 15-to-30–minute clips from some of the best podcasters—and also best interviewees—in the world and certainly some of my favorites.

At the beginning of each clip, you will hear an intro from the host and where to find their work and podcast. I’ll also share one or two of my favorite clips from episodes of The Tim Ferriss Show.

You can view this episode as a buffet, and I strongly suggest that you check out the shows included. If you like my podcast, you will very likely enjoy the featured shows in this episode.

And before you go: Do you like this format? Please let me know on Twitter at @tferriss and also mention @TeamTimFerriss.

Please enjoy!

This episode is brought to you by Pique! I first learned about Pique through my friends Dr. Peter Attia and Kevin Rose, and now Pique’s fermented pu’er tea crystals have become my daily go-to. I often kickstart my mornings with their Pu’er Green Tea and Pu’er Black Tea, and I alternate between the two. This rare type of naturally fermented tea is more concentrated in polyphenol antioxidants than any other tea—it supports focus and mental clarity, healthy digestion, metabolism, and a healthy immune system. Their crystals are cold extracted, using only wild-harvested leaves from 250-year-old tea trees. Plus, they triple toxin screen for heavy metals, pesticides, and toxic mold—contaminants commonly found in tea. I also use the crystals for iced tea, which saves a ton of time and hassle.

Pique is offering up to 20% off of their pu’er teas, exclusively to my listeners. To sweeten the deal even more, you’ll get a free sampler pack with 6 of their best-selling teas. Simply visit PiqueLife.com/Tim, and the discount will be automatically applied. They also offer a 30-day satisfaction guarantee, so your purchase is completely risk-free. Just go to PiqueLife.com/Tim to learn more.

This episode is also brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system.

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and five free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.
