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...

How to Exercise with An Autoimmune Condition

Autoimmune diseases really throw the body for a loop. You’re attacking your own tissues. Your inflammation is sky high. What’s usually good for you—like boosting the immune system—can make it worse. You’ll often restrict eating certain foods that, on paper, appear healthy and nutrient-dense. You take nothing for granted, measure and consider everything before eating or doing it. Sometimes it feels like almost everything has the potential to be a trigger.

Is it true for exercise, too? Must people with autoimmune diseases also change how they train?

19 Personal Care Products I Use or Like

A few years ago, I wrote a long post listing cosmetics, soaps, and other personal products made with healthy, non-toxic ingredients. It’s a sad thing when you basically have to assume the worst about the average product designed to be slathered all over the largest organ of your body—your skin. But that’s the situation in which we find ourselves now.

Today’s post is an update of sorts. What products am I using? Which ones have I used? And are there any others that I can safely recommend? It won’t be as comprehensive as the last one. It will be more personal.

Dear Mark: Infrared Sauna Roundup

After last week’s post on infrared saunas, people asked some good questions. For today’s edition of Dear Mark, I’m answering a few of them. First up, can infrared saunas harm male fertility? After all, they do penetrate the skin and raise body temperature, which is a no-no for sperm. Next, infrared saunas induce lots of sweating, and sweat contains bioaccumulated toxins like BPA and heavy metals. Can infrared saunas help us shed these toxins? Finally, are infrared-emitting blankets and other “topical” infrared products effective alternatives to infrared saunas?

Let’s go:

Are Infrared Saunas Beneficial?

Last month, I installed an infrared sauna in my house. A company offered it to me to try out, and I was willing to give it a go, knowing a little about them already. It also inspired me to dig into the research—to test it personally but also to see what studies had demonstrated in terms of benefits. I’ll say I’ve been pleased with what I’ve found from both angles.

Over the past few weeks, I’ve been following a new bedtime ritual: a half hour in the sauna, a cold plunge in the pool, bed. The reasoning is that after warming up my tissues in the sauna, I drop them back down to prepare for sleep. So far, it’s working. I wasn’t exactly starting from a deficit—my sleep has been consistently good ever since I changed how I consume alcohol—but I’m really happy with the new setup.

Why infrared?

A traditional sauna heats the air around you. An infrared sauna uses infrared light to penetrate your skin and warm you directly without affecting the ambient temperature. This makes them great for home use.

A Primal Look at Skin Care

By next year, Americans are expected to spend nearly 11 billion dollars on skin care annually. By some estimates anyway, the biggest share of this market goes to “anti-aging” products. Anti-aging… As I noted in an offhand way a few years back, there’s a certain enjoyment in looking good naked (or just looking good), and there’s nothing wrong with that. Looking “good” is largely a reflection of optimum inner health—nothing un-Primal about that. Great health is what we’re all here for. The “extra” rewards that come with it aren’t anything to shake a stick at—or to be sheepish about.

But the health ambition isn’t really what’s behind the statistics above. At their best, anti-aging products boost the body’s natural processes (or at least don’t undermine them with toxins). At their worst, these products promise a way to cheat effort as well as time. While taking care of your skin is part of basic hygiene, too often the claims have more in common with a hat trick than genuine wellness. But which is which?

Let’s discuss….

Dear Mark: Egg Replacements, Bruxism, Fermenting Frozen Veggies, and Ferments While Breastfeeding

For today’s edition of Dear Mark, I’m answering four questions. First, I give a few options for recreating, or at least approximating the emulsification power of the mighty egg yolk for a reader who’s allergic (and give a quick preview of an upcoming Primal Kitchen product). Next, I explain why people with sleep apnea often grind their teeth, and mention an nutritional factor that might also cause grinding. Third, can you ferment frozen vegetables? Should you ferment frozen vegetables? And fourth, is fermented food safe while breastfeeding?
