Study: The Link between Body Temperature and Physical Activity

I used to supply prolonged commentary on new analysis in a weekly collection referred to as “Monday Musings.” I’d cowl and summarize a research or two or three, give some commentary, and open it up for questions from the readers. It was a enjoyable and informative technique to spend a Monday. Well, with increasingly analysis being printed than ever earlier than, and increasingly folks being serious about well being than ever earlier than, I figured I’d resurrect the observe and start analyzing new analysis in short, digestible chunks.

First research is “Historical body temperature records as a population-level ‘thermometer’ of physical activity in the United States.”

I’m not a chilly climate man anymore. Years of residing in Malibu and now Miami Beach have softened me. I’ll admit that readily. But again after I was a child in Maine, I used to courageous these chilly blustery (even snowy) days with out a lot in the way in which of chilly climate clothes. My pals and I might keep out all day lengthy and by no means cease transferring, by no means actually feeling the chilly. We weren’t on the market shirtless or something, however we additionally weren’t sporting 4 layers. We weren’t bundled up.

And even now, after I go snowboarding, I can’t bundle up too closely. If I’m actually staying in movement, I’ll be in brief sleeves or else I get too scorching. The secret is transferring. All it’s important to do is transfer and the chilly simply bounces proper off you.

That’s the premise of this new research, which makes use of physique temperature information to gauge the extent of bodily exercise within the United States during the last hundred years or so. The authors suggest that greater physique temperatures imply better bodily exercise. And that’s a reasonably sound conclusion, however I don’t suppose it’s all the story. There are different elements that may decrease physique temperature.

The one which leaps out at me is our linoleic acid consumption from seed oils. Over the previous 50 years or so, we’ve eaten extra seed oils than ever earlier than and the linoleic acid content material of human physique fats has elevated by 136%.

Why does this matter?

Hibernating animals are likely to massively improve their linoleic acid consumption with a view to deposit tons of it of their physique fats within the weeks main as much as hibernation. This induces torpor, a state of low physique temperature, physique fats acquire, and very low bodily exercise—so low that they don’t transfer in any respect. Does that sound acquainted? Brad Marshall, the “croissant diet guy,” has been specializing in how linoleic acid consumption regulates torpor and thus physique temperature and metabolic price for the previous couple years. It occurs to all mammals, not simply squirrels, bears, and mice. Humans will not be exempt from the metabolism-depressing results of extreme linoleic acid consumption.

The second research is known as “The effect of vitamin D and magnesium supplementation on the mental health status of attention-deficit hyperactive children: a randomized controlled trial.”

These had been Iranian children aged 6-12 with identified ADHD who additionally had magnesium and vitamin D deficiency. One group received 50k IUs of vitamin D every week and 6 mg of magnesium/kg of physique weight day-after-day at lunch; the opposite group received placebo capsules and tablets. So if you happen to had been an 80 pound (roughly 36 kg) child, you’d get 216 mg of magnesium. Sadly they didn’t point out what type of magnesium, however no matter it was, it managed to extend serum magnesium ranges.

What was the consequence?

Kids who obtained vitamin D and magnesium had fewer emotional issues, behavioral points, peer issues, and “total difficulties” than the management group obtained no dietary supplements. This is an easy intervention with little or no draw back—in truth, the supplementation group had no uncomfortable side effects in any way, not even the upset abdomen that may consequence from lower-quality magnesium dietary supplements—and many upside. There’s a superb likelihood that the majority children have a minimum of subclinical magnesium deficiency, and we already know that magnesium deficiency is linked to many critical circumstances kids undergo from, like kind 1 diabetes and leukemia. Magnesium supplementation is a low-cost, basically “free” intervention to attempt on nearly each little one on the market.

What about magnesium from meals? Sure, that’s nice. Almonds, most legumes, pumpkin seeds, winter squash, fermented dairy are all fairly good sources of magnesium, however supplementation could also be warranted as a result of meals magnesium ranges have been dropping from historic ranges. In different phrases, the quantity of dietary magnesium our physiologies are used to getting on a historic and evolutionary foundation are now not current in most fashionable meals.

If you may’t get your children to take magnesium drugs, you may simply work it into their diets.

Blackstrap molasses in milk.

Magnesium chloride powder sprinkled of their consuming water.

Magnesium-rich mineral water like Gerolsteiner.

Anyway, that’s what I’ve received for at the moment. What do you consider these research? I’m curious to listen to your reactions. Until subsequent time.
