Circadian Rhythms in Modern Life



By Vladimir Heiskanen This paper discusses the Western human circadian rhythm and its relation to health. 1. The circadian rhythm of a modern man “In 1910, the average American slept nine hours a night, disturbed only by the occasional Model T backfiring. We now average 7.5 and declining.” – Robert Sapolsky (Why Zebras Don’t Get Ulcers) The typical Western person’s circadian rhythm differs in at least three main ways of which the human species has adapted to in its history First of all, the amount of light during night time. Before artificial lighting popularized, people spent the night in almost complete darkness . Today, most families live in almost constant light even if it is pitch black outside. Second, the amount of light during the day is now lower than it… Read more »

Earth Runners Earthing Shoes


grounded symbiosis

The following, and everything published at 180DegreeHealth is NOT a paid promotion.  By Matt Stone I admit – I have dabbled in the world of peculiar health-oriented footwear – to some degree.  For a couple years I wore a pair of those fugly Vibram 5-Fingers shoes.  They were alright.  I used them mostly for hiking in mountains and desert – hard on the feet but good on the body, as you had to walk carefully and gingerly to an extent that a lot less shock was being sent up into the knees, hips, and back. But my feet never really adjusted to the lack of protection because I just couldn’t bring myself to wear them daily.  While the internet gives me electric courage (similar to the liquid courage of alcohol),… Read more »

Reducing Serotonin Levels



I’m not a fan of exhaustive lists that are meant to cover absolutely every possible way that some miscellaneous biochemical, of which there are a bajillion, are affected by our diet and lifestyle.  Trying to simply research one of them recently, serotonin, has nearly turned my brain into scrambled eggs.  Actually, that’s a terrible metaphor as my brains probably look, taste, and have some nutritional similarities to scrambled eggs regardless of my current research project (snoop du jour?).  But you know what I mean. In the last post I discussed some of the dangers of serotonin.  When looking at the big picture of aging, inflammation, mitochondrial respiration, metabolism – that stuff that is a recurring theme in almost all illnesses, serotonin is worthy of mention.  It’s not worthy of mention… Read more »

10 Health Reasons to Spend Time Outdoors


great outdoors

This summer I toured around the Rocky Mountains with my girlfriend and her daughter, showing them many of the remarkable places and doing many of the remarkable things in the outdoors (like crapping in a hole) that I’ve been extremely privileged to experience.  In the past I have reaped many health rewards from spending a lot of time in the outdoors (I’ve experienced some health detriments as well, from overdoing it with physical exertion and underdoing it on food). I think the near-miraculous health benefits I have experienced from spending a lot of time outdoors in the past was one of the major catalysts for my interest in health.  The only problem was that the quantity of time spent outdoors to achieve that effect was extreme – not something any “normal” person… Read more »

Intuitive Eating


Intuitive eating – which is best described as eating what you want, when you want, because you feel like eating it (with or without a “damnit!”) – is a great concept. Sure, it has limitations. One is that superstimuli such as artificial sweeteners, flavor enhancers, and pornographically-delightful foods like chocolate, cupcakes, Mountain Dew, and potato chips often induce us to eat, not for hunger’s sake, but out of an empty pleasure-seeking compulsion (sort of that “just one more” feeling you get when flipping through channels at the end of an unsatisfying day, or hopping around from site to site on the internet with that subtle whisper for gratification in the back of your mind). But it’s worth recognizing how much more intelligent our bodies are than our minds when it… Read more »

Resetting Your Circadian Clock


Your typical health geek knows very little about Circadian rhythms, but real researchers know that there is a tremendous significance behind our daily biochemical rhythms. For those that don’t know, the circadian rhythms are basically just secretions of various chemicals and enzymes that take place during the 24-hour cycle that are set like a clock. For example, during the evening it is natural for humans, a diurnal creature, to see a drop in cortisol and a rise in serotonin. This kills your appetite and makes you calm, sleepy, and ready to hit the hay after the sun goes down. In the morning you see cortisol peaking in a normal, healthy human with ideal circadian rhythms. This helps to promote hunger, whereas having low cortisol levels throughout the night lends itself… Read more »
