Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

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 creatures, we’re living, breathing humidifier-refrigerator-landlords who charge extremely competitive rates. Why wouldn’t they infest us?

In the last couple weeks we’ve taken a look at sleep posture, how to improve it, and modern bedding. Today we’ll take a closer look at your mattress, investigating what may be lurking inside and what you can do about it.

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 mats, or piles of leaves, or animal skins, or even just the bare ground, and they – by and large – managed to avoid the musculoskeletal disorders that plague modern sedentary man. Should we follow suit, ditching our sumptuous sleeping setups for something more Spartan? Are health benefits conferred by slumbering on something Grok would recognize? Or put another way, are our beloved pillow-topped mattresses doing more harm than good?

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 no different. Of course, there is a limit to our adaptability. We couldn’t survive in the Antarctic or get a good night’s sleep in a mud pit. Thriving in the current food environment is definitely doable, but, as you well know, it takes a lot of effort to make it work. Luckily, we aren’t dealing with hydrogenated mattresses or high-fructose pillows, so the bedding situation isn’t so dire.

You can keep it pretty simple, in fact: if you’re getting good, pain-free sleep already, hacking isn’t necessary. Just keep doing what you’re doing and keep the bed you’ve got. (Keep reading, though.)

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 you’ve got sitting in your chest freezer, deconstructed. You’re even toying with the idea of ditching shampoo. Sheesh. To outsiders, you’re that weird caveman guy who eats steak for lunch and keeps a jar of coconut oil at his desk and thinks he’s living in the Paleolithic, but really, you’re just someone who’s discovered that keeping an ear, an eye, and a foot in our ancestral past makes living in the present that much more fulfilling – and healthy.

But how far do you go? What about sleeping? (Here come those questions…) Should we care how and upon what type of bedding Grok slumbered?

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, however, about the upper ceilings I would set for various elements of the PB (fat, fish oil, etc.) I thought I’d take on those questions today and cover good ground by applying a rapid fire approach for several of the most common “excess” inquiries. Enjoy, and be sure to share your thoughts!

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 change these days, but probably just as many stayed up late to watch the NCAA games this weekend. Or maybe it was a late St. Paddy’s Day party. Somehow it’s always somethin’, isn’t it?

Even if we’re good and diligent and never sacrifice sleep for entertainment purposes, life too often pokes holes in our most worthy intentions. Babies wake up in the middle of the night. Flights leave early. Deadlines, projects and bills keep us up later than we’d planned. Maybe we even burn the midnight oil to get a jump on the next morning’s tasks! Nighttime too often becomes a default slush fund for the day’s chores. Still others of us might deliberately stay up to bask (however groggily) in what seems like the only time we have to ourselves. The house is quiet, the kids/partner are asleep. The world is hushed, and the deep solitude is too much to resist.
