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 Should We Harness Behavioral Economics for Better Health?

As much as humans think they’re objective beings whose every decision emerges from cold logical calculation, we’re just irrational, emotional animals. That’s why stories and anecdotes are more convincing than facts, why people fear losing money twice as much as they enjoy making it, and why the guy making $100k per year feels poor if his neighbors make twice that. This kind of phenomenon is best explained by behavioral economics, a method of economic inquiry that uses psychological, emotional, cognitive, and social factors to explain why we make the often-irrational financial choices we do. And it has some interesting applications for health….

5 Unconventional Ways to Extend Your Life

I’ve written about extending your life by slowing down the apparent passage of time. I’ve written about some interesting predictors—but not necessarily causes—of longevity, and the common characteristics of centenarians. Today, I’m going to describe several unconventional causal means of extending your life.

I’m talking about cold, hard days, weeks, and months. Ticks on a clock. Objective measurements of time. Not just the perception of time, although that matters too.

7 Primal Mantras to Drive Your Success

Do you have any mantras? You should.

Ignore the pseudo-spiritual baggage many people have with the notion of a mantra. Repeating and focusing on a meaningful phrase to help guide you through difficult situations, whether that’s an hour of sitting meditation or a commitment to a healthy Primal lifestyle, is a legitimate tool anyone can use. Today, I’m going to give you 7 mantras that I find to be useful.

Many of these don’t even apply explicitly to nutrition or fitness, so anyone can gain from incorporating them. I even left off a personal mantra of mine—”Rend the flesh of young mammals and consume it close to raw as possible”—to make vegetarians and vegans feel more welcome.

The Empathy Effect: How Befriending Your Future Self Can Impact Your Health Today

You are not the person you were fifteen years ago. The cells that compose your tissues and deliver oxygen have been recycled many times over. Your face has changed. You move differently. You’re probably slower and weaker, or, depending on your daily habits, faster and stronger. As it becomes available, you incorporate new information into your belief system. Even the neat narrative we imagine we’re orchestrating unbroken in our heads has nightly intermissions lasting hours during which we have no real clue what happens.

Is this all just philosophical navel-gazing better suited for 2 AM in a dorm room covered with Bob Marley posters? Not exactly. Accepting the idea that past and future selves are different people can have real benefits today—and tomorrow.

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?

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.
