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 […]

Dear Mark: Sleep and Oxidative Stress

Dear Mark, The time change pretty hit me hard this year. I’ve noticed that as I age I value my sleep more and more. When I was in my 20s and 30s I use to be able to get by on about 6 hours of sleep each night. Now if I don’t get at least […]

How Light Affects Our Sleep

Most people are at least cursorily familiar with the concept of the circadian rhythm. For those who aren’t, the circadian rhythm refers to our internal, approximately 24-hour cycle of biochemical, physiological, and behavioral processes. Every living thing, from fungus to bacteria to plant to animal, has a circadian rhythm. External cues called zeitgebers (what a […]

Dear Mark: Time Change

If you ask people whether “falling back” or “springing forward” hits them hardest, most will say spring. (I’m in this camp also.) I’ll admit that I love the extra hour of sleep in fall but dread the reverse a few months later. Switching the clock (in either direction) can leave you feeling oddly displaced, like […]

Dear Mark: How to Stay Healthy in College

College students and healthy lifestyle. On the one hand it seems like the ultimate contradiction. Pizza boxes, Red Bull cans, Doritos bags, beer bottles, Captain Crunch at every cafeteria meal. They’re as much a cultural vision of college as John Belushi’s sweatshirt. If there were a Primal no man’s land, you’d think the residential campus […]

The Primal Blueprint for Busy People – Part 1: Sleep and Stress

Last week we took on the eternal “no time” excuse in our “No Better Time than the Present” post, and we were thrilled by the response. Readers offered their own efficiency strategies as well as continuing challenges for fitting in all their Primal goals. Busy. Hectic. Maybe a few moments of frantic thrown in there. […]

Grok Never Needed an Alarm Clock, So Why Should You?

It goes without saying that Grok never had to resort to a shrieking alarm clock to get him up in time for the day’s activities. But he also never had to worry about beating rush hour, or getting his little Groklings to school. Even if we subscribe to all the other behaviors of our ancestors […]

Natural Headache Remedies

Months ago, we discussed natural alternatives to OTC pain relievers. Now, before you assume I’m some hippie snake oil peddler, mine is not a blanket, ideological opposition to pharmaceuticals; rather, it’s just that if there are more natural, cheaper, less intrusive ways to relieve pain, why not try them first? But that last post was […]
