Andrew Huberman helped push mouth taping into the mainstream. Here's what he actually recommends, the physiology he cites, and how to apply it — with the honest caveats he includes.
Sleepmaxxing can backfire. Obsessive tracking, orthosomnia, and 47-step routines create the anxiety that wrecks the sleep they're meant to improve. Here's the honest counter-argument — and what actually matters.
Your bedroom is a sleep machine, and most people have it configured wrong. Here's the room-by-room, factor-by-factor checklist — temperature, light, sound, air, and bedding — to turn it into an environment that produces sleep.
Magnesium glycinate is the most-recommended sleep supplement — for good reason, but with important nuance. Here's what the research supports, who actually benefits, the right dose, and why the form matters.
Supplements get the attention, but three cheap physical tools — mouth tape, nasal strips, and a weighted blanket — address sleep mechanically in ways pills can't. Here's how they stack.
Sleep trackers are useful for trends and terrible for absolute accuracy. Here's what Oura, Whoop, Garmin, and Apple Watch actually measure, what to trust, what to ignore, and how to avoid orthosomnia.
You can't slam from a stimulating day into sleep. A wind-down routine bridges the gap by shifting your nervous system and physiology toward sleep. Here's the 60-minute protocol built on what actually moves the needle.
Box breathing is the simplest, fastest-acting sleep-onset technique I've found. Originally popularized by Navy SEALs for high-stress performance, it works at bedtime for the same reason it works in combat — direct parasympathetic activation. Here's the protocol and the physiology.
Most plane-sleep advice is the same five tired tips. Here's the protocol I run on long-haul flights — what to pack, when to eat, when to sleep, and the small interventions that make the difference between landing wrecked and landing rested.
Most 'fall asleep faster' advice is the same five tired tips recycled. Here are the seven that actually move sleep latency — ranked by effect size, with the protocol that combines them.
Some bedtime foods sedate you while quietly destroying sleep architecture. Others spike blood sugar, raise core temperature, or stimulate cortisol. Here are the seven worst offenders — ranked by damage done.
Most blue light glasses are useless for sleep — clear or pale-yellow lenses block almost nothing in the wavelengths that suppress melatonin. Here's what to look for, and the inexpensive pair I actually wear.
Most magnesium supplements are oxide-padded filler at 4% bioavailability. The honest brands tell you elemental content per pill. Here's the side-by-side after testing seven of the top products.
If you have $500 to spend on a sleep tracker, the smart play is rarely the most expensive option. Here's what each format actually measures, what it misses, and which one fits your situation.
Blue light glasses only work if you wear them at the right time. Putting them on 30 minutes before bed is too late. Here's the exact protocol — when to put them on, what to do alongside them, and what to expect after the first week.
Most sleep advice is a long list. The two interventions that actually compound — one for falling asleep, one for staying asleep clean — are 400mg of magnesium glycinate before bed and a small strip of tape across the lips. Here's why they work together and the exact pair I use.
If you've been taking magnesium for sleep and getting underwhelming results, there's a good chance you're a nighttime mouth breather and no supplement is going to fix that. Here's how to tell, and what to do about it.
I've taken Pure Encapsulations Magnesium Glycinate every night for the last three months. Here's the honest review — what it actually does, what it doesn't, and why I keep coming back to this specific brand over the cheaper Amazon options.
The definitive evidence-based playbook for optimizing your sleep — five dimensions, ranked by impact, with a 5-week rollout. Skip the gimmicks. Run the protocol.
Most sleep advice is one tool repeated 50 different ways. Here's the actual stack — seven specific interventions, each addressing a different dimension of sleep, that compound.
Glycine costs about $0.05 per night. The research shows it improves deep sleep, reduces sleep onset, and leaves you feeling sharper the next day. So why is no one talking about it?
L-theanine is the amino acid from green tea that quiets the racing mind without sedation. The research is solid, the dose is small, and the side effects are essentially zero.
Magnesium is the most-recommended sleep supplement on the internet. The research is real — but most people buy the wrong form, at the wrong dose, at the wrong time.
Melatonin is the most over-dosed supplement in America. The research-optimal dose is roughly 10× smaller than what you can buy at any drugstore. Here's the science.
