Dear Mark: Bacon Fat Stability, Noise Machines, and Pig Feed

Is there any food more lauded and feared, beloved and bewitching, hated and praised – all at the same time – than bacon? Have full-fledged Internet subcultures sprung up around any other animal product? Does any food but bacon inspire obvious longing masquerading as righteous rancor and vitriol? And yet no matter how much has […]

How to Conduct a Personal Experiment: Yellow Light Exposure (plus an Announcement)

You guys ready for another personal experiment? I hope so. Even if don’t think you’re ready to take something on, I’m confident you’ll be able to handle this one, because it’s relatively simple, intuitive, and easy. It’s also something I’ve been discussing for a couple years now, so you’re most likely familiar and comfortable with […]

How to Conduct a Personal Experiment: Biphasic Sleeping

It’s time for another edition of “How to Conduct a Personal Experiment.” Last week, it was the cold water plunge. Today, we’re going to talk about running a biphasic sleep experiment. First, though, I’d like to know: how are the cold plunges going? Are they, well, cold? More importantly, did you have any difficulties setting […]

The Importance of Dreaming

Some consider it the ultimate Primal ground – a terrain unapologetically wild and forever untamable. It’s the last place a man or woman can live out every deep seated instinct and inclination with no interference from cultural authorities, no entanglement with others and their needs or opinion. I’m talking of course about dreams. (Those titles […]

Primal Experiment: Intentional Power Outage

A few months back, I linked to an article about a guy who experienced an unexpected benefit after Hurricane Irene knocked out his power for several days: he started sleeping much, much better. Instead of staying up late on the computer or with the TV blaring and going to bed at the usual 11:30 or […]

Dear Mark: Late Night Work Shifts

Ah, sleep. We need it, we love it, we crave it, we promise ourselves that we’ll get more of it, and yet quality sleep remains out of reach for so many of us these days. Some do it to themselves, staying up late to watch bad TV (or great TV, which is more understandable) and […]

How to Wake Up and Feel Alert

Have you defeated the fearsome sleep beast that plagues so many of your countrymen? You might think you have – after all, you installed blackout curtains in the bedroom, disconnected every LED-light before hitting the sack, peer through slitted eyes at a F.lux-altered computer screen, get seven to nine hours a night, and make getting […]

Poor Sleep May Make You (and Your Liver) Fat

Ah, sleep. Nothing like a good dose of the stuff, right? Losing even a single wink of your usual forty (or an hour, as the case may be) is enough to throw off an entire day. But do you know who might love sleep more than anyone or anything? Our livers. Yes, livers. Those fleshy […]

Is “8 Uninterrupted Hours a Night” Flawed Conventional Wisdom?

Conventional Wisdom always gets an eyebrow raise from me. I can’t help it. Eventually, I take an honest look at whatever the experts are saying, but skepticism gets first dibs. I’d call it an instinct if it weren’t learned behavior from years of being burned. For example, I once took to task the most pervasive […]

17 Ways to Improve Your Sleep

Like last week’s stress post, I’m not going to delve deeply into why sleep is so important. I’ve done it before, and doing so again would simply take up valuable space that’s better used for action items – for actual sleep hacks that you can put into effect immediately. Just rest assured that it’s crucial […]

Monday Musings: Poop Transplants, Sleep Deprivation and Going Nuts

And now for another round of Monday Musings… Let’s Talk Sh** Poop is the new probiotic. Doctors have been using fecal transplants as a “last resort,” mostly to treat the rising scourge of Clostridium difficile, a gut bug that affects about 250,000 Americans every year and proves extremely resistant to antibiotics. Shooting a fecal extract from […]

Vibrant Health is About More Than Food

I’ve been thinking about human health for a long, long time – pretty much my entire life. When I was running marathons and battling injuries and illness, I was missing it, and so I sought it. I figured moving on to triathlons would help, maybe by “spreading the damage” across three disciplines, rather than just […]

Sound Cues and Circadian Rhythms

Yesterday, I showed how environmental, behavioral, and social cues act as zeitgebers to human circadian rhythms, and I tried to be as thorough as possible (without outstaying my welcome). I left out one very important environmental cue with the promise of more information today – sound. I can’t recall exactly where I heard about it, […]

Circadian Rhythms: Zeitgebers, Entrainment, and Non-Photic Stimuli

For all the unchecked randomness in this world, there are at least some things you can count on. The sun always rises and it always gets dark, and that’s something life – all life – has learned to rely on. Our internal clocks, known as circadian rhythms, tend to match up with this established external […]

Dust Mites, Off-Gassing and What to Do With Your Mattress

Dust mites are everywhere. They are true survivors, able to make it in virtually all climates and at any altitude. They thrive, however, in our homes, especially bedrooms, enjoying the humidity generated by all the breathing, perspiring, and drooling we do at night and feeding on all the skin flakes we produce. For these tiny […]

Bedding: Do We Really Need It?

The massive, California king body-molding Tempurpedic mattress that can balance a glass of Cab even as the red-faced TV pitchman hops up and down on it on his way to the next infarction, is a recent invention. Our ancestors were not hauling these massive things from kill site to kill site. They made do with […]

How to Improve Your Sleep Posture

Yesterday, I posited that it’s not so much the bedding that matters in making for rejuvenating, nourishing sleep, but rather our sleeping position/posture. Man is the supreme adaptor, having proven himself capable of surviving in just about any natural environment, no matter the climate, topography, and available selection of edibles – and our bedding is […]

Does It Matter How Grok Slept?

Since you’ve gone Primal all sorts of strange questions pop into your head. And since you’ve gone Primal life has definitely changed. You wore Vibrams to your last shareholder meeting. The idea of skipping two, or heck, three consecutive meals, seems perfectly reasonable, and your idea of a frozen treat is that local, pastured lamb […]

How Much Is Too Much?

Although the Primal Blueprint leaves ample room for individual determination, I do try to offer folks a clear picture of the impact different dietary and lifestyle choices have on their overall health picture. At times I even offer specific recommendations or ranges that readers can tailor to their particular needs and situations. I’m often asked, […]

The Definitive Guide to Sleep

Sleep Awareness Week (as sponsored by the National Sleep Foundation) technically ended March 13th, but somehow I’m guessing there are just as many sleep deprived folks milling about this week as there were a few days ago – just like our good reader Monday. Maybe a few of us feel better adjusted to the time […]
