The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate...
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...Tell Me More
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 – diet, fitness, rest, relaxation, play – it is our reliance on external, artificial rousing mechanisms that’s the hardest vice to shake. One could even argue that modern (corporate) culture requires the use of an alarm clock. How else are we to manage our most precious commodity of all, time?
No matter how closely we follow the Primal Blueprint, dips in energy are bound to hit from time to time. Last week, I identified a bunch of tricks for getting yourself out of the hazy afternoon slump. The most popular – and most elusive, I’d imagine – was the afternoon power nap. There’s nothing like taking a quick one to restore energy, but sleeping on the job simply isn’t feasible for a lot of the work force. If you work outside or share a tiny cubicle with a couple other people, we can’t help you. But if it’s your boss giving you grief about a little naptime, there are ways around that.
Glazed over eyes. Slumped shoulders. A suddenly weighty cranium that keeps dipping toward the keyboard. Even heavier eyelids. Eyes that constantly sneak peeks at the clock, which seems to tick ever more slowly (the more you look). Work piling up without regard for your inability to acknowledge its presence.
My apologies for the string of sentence fragments, but my mind simply isn’t working quite right. I’m in the midst of ruminating on the dreaded mid afternoon slump. For my money, it’s the worst feeling in the world.
In the past, we’ve highlighted the importance of sleep in our lives as evidence mounts. A healthy amount of the stuff can help with memory, and a study showing that those who toss and turn to the tune of five or fewer hours of sleep per night have a higher incidence of “silent” heart disease suggests its importance in cardiovascular health. But it’s not like we needed science to tell us that getting plenty of sleep was good for us; the sluggish thoughts, rotten moods, and general uselessness we experience on inadequate sleep is our body’s way of telling us to sleep more and sleep better.
A study in a recent issue of the Journal of the American Medical Association suggests that sleep is an integral ingredient for heart health.
For the study, researchers from the University of Chicago outfitted 495 healthy, middle-aged volunteers with actigraphs, a device worn on the wrist to measure movement and rest.
Accounting for some degree of movement during sleep time – hey, we’ve all been there with the tossing and turning! – the researchers determined that the study participants slept an average of 6 hours per night but spent about seven hours in bed, presumably waiting to fall asleep.
While we here at MDA like to pay close attention to our bodies and use common sense to help determine what is and isn’t healthy, actual scientific evidence forms the backbone of our philosophies. We scour breaking health and nutrition news releases to make sure our ideas are supported by science. It’s important, we think, to present a multifaceted case for the Primal Blueprint as the ideal lifestyle choice, because years and years of being barraged by low-fat diets and rabid calorie-counting espoused by “experts” has inured your average person against the PB.
