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...

The Power of Daydreaming: Why You Should Let Your Mind Wander

There’s something about these middle weeks of summer that feel less hurried, less brimming, more casual. At a certain point of the season, everybody remembers to relax a little and soak it in. The “lazy days” mood got me thinking about daydreaming – those lost minutes (maybe hours) in which we unintentionally slip into contemplation. Sometimes we end up floating into more serious ruminations. Other times, it’s just loose and happy reverie. We all do it – whether it’s looking out the window of our morning train, laying in the backyard hammock, or sitting (standing, rather!) at our work desk. It can often happen even if we’re trying to focus. Call it a lapse in discipline, but the brain seems to have its own agenda in those moments. Is there some purpose here beyond mere escapism? What is the brain really up to, and what could daydreaming have to do with well-being?

Dear Mark: Personalizing the Primal Blueprint

Primal life is good. You’ve lost some weight, improved some health markers, enjoy steady even energy throughout the day, and you finally look forward to exercise (and movement in general) for the first time in a long while. You love the food, and the compliments you’ve started receiving since beginning to eat it, and you’re generally content, but something’s missing. It’s not that you aren’t satisfied; it’s that you’re curious about what else you can tweak to make your body work a little differently. You want to see what makes your body tick, and why, down to the very last detail. I get that.

Luckily for you, your experience and the resources in this community give you the necessary wherewithal to find out. Let’s go to the question that prompted this post, shall we?

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 the concept. But most importantly, today’s experiment is a gentle one that requires very little commitment. No jumping in freezing cold water, no drastic changes to your sleeping schedule. All I’m asking you to do is experiment with nighttime yellow light exposure.

Huh?

Remember how I wrote about nighttime exposure to blue light affecting melatonin secretion and, subsequently, sleep quality and duration way back when? Yeah, that. In case you didn’t read it, I’ll give a quick explanation:

How to Work Outside (Even If You’re a Desk Jockey)

Last week, I told you why working outside – at least from time to time – can be helpful, relaxing, and even performance-enhancing. A number of you emailed me directly, or left comments thanking me for the idea. Most people were on board with working outdoors, but mostly in theory, because let’s face it – being outside on a workday with the sun shining and the birds chirping and the breeze blowing sounds fantastic, but how realistic is it, really? Even if you’re able to convince your boss to let you take the work outside, or you find a job that gives you the freedom to work where you like, the logistics of seamlessly moving a traditionally-indoor activity to the outdoors just seem insurmountable. How are you gonna get Internet access? How will you read your emails through the glare of the sun?

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 up the experiment, identifying variables, and choosing what to measure and track? This whole personal experiment stuff is likely new to most of you, and while there’s no real “wrong” way to go about it, there will be some initial difficulties. Be sure to keep us posted in the comment section.

Okay, on to the new experiment.
