Summary
Paul Saladino covers sleep optimization from multiple angles, including the effects of caffeine, alcohol, and marijuana on sleep quality. He discusses how grounding may impact circadian rhythms, breaks down REM vs. non-REM sleep, explores optimal sleep duration, and shares his personal morning and nighttime routines for maximizing sleep quality.
Key Points
- How caffeine, alcohol, and marijuana affect sleep quality
- Grounding and its potential impact on circadian rhythms
- REM vs. non-REM sleep and their distinct functions

- Paul's personal morning and nighttime sleep routines
Key Moments
Grounding sandals maintain earth connection daily
Saladino discusses grounding sandals as a way to stay connected to the earth without going barefoot.
"How cool is this? So, if you don't want to go barefoot, you don't want to cut your feet, you can be grounded to the earth. You can get that electrical conductivity, that electrical normalization with the earth that I talked about in the grounding episode with a pair of shoes on. So how cool is this? This is totally incongruence with ancestral wisdom. And man, it just feels good to be grounded and it doesn't feel good to cut your feet. Again, they're a minimalist soul, a vibrant soul, full range of healthy foot motion with improved weight."
Morning sun + barefoot grounding as daily routine
Saladino shares his protocol of standing barefoot on the ground in sunlight for 5-10 minutes each morning to combine grounding with light exposure.
"If you've seen my reels, I turn the Wi-Fi on and I go outside in the sunlight and I stand on the ground. So I am grounding first thing in the morning. I did a podcast a few weeks ago with Clint Ober on grounding, and one of the most interesting parts of that podcast was this idea that as the Earth rotates on its axis, there appears to be a testable, reproducible electrical signal in the earth that is different. So there may be some circadian rhythmicity to grounding as well, which means I'm not just going outside and sitting on my deck, wood deck. I want to touch the earth with my feet and ground first thing in the morning. I'm also now using a grounding mat when I'm sleeping and And when I am doing the podcast, I'm grounding as much as possible. I'm really fascinated by this. Again, refer to the podcast with Clint Ober if you're interested in that. But as I go to Greece, I'm going to do an experiment on jet lag and this idea that will my jet lag be worse? I think Greece is nine hours ahead of where I am in Costa Rica right now. So it's quite a significant jump. Will my jet lag be any worse or better if I try and ground? So the goal is to fly to Athens and get in the ocean as soon as possible for 15 to 20 or 30 minutes to try and ground in Athens."
Grounding during sleep normalizes cortisol rhythms
A study of 12 subjects showed grounding during sleep synchronized morning cortisol spikes, suggesting benefits for sleep and jet lag.
"Some coalescence of a peak at 8 a.m., but after grounding, there's a clear pattern towards synchronization of this morning cortisol awakening spike."
