Health and fitness learnings for March and April: “the human body loses about 8 ounces of water per hour on an aircraft at altitude, mostly from breathing”

Snack on pumpkin seeds. One ounce of seeds contains more than a third of your recommended intake of magnesium. According to Mildred Seeling, M.D., author of The Magnesium Factor, magnesium deficiencies have been linked to most risk factors for heart disease, including high blood pressure, elevated cholesterol levels, and the increased buildup of plaque in the arteries.

Jeff Wang: would NOT mess with ashwagandha. too many people i know got bad liver markers from them, including me. cycle off every 2-3 months if you do

Apple cider vinegar (ACV) can be an effective digestive aid. It can help to calm stomach discomfort associated with indigestion, reflux, bloating, or fullness. While studies have not been done to analyze how ACV works, the acidic nature of apple cider vinegar and other types of vinegar may support better stomach pH.

It takes 3-7 days from last drink to fully detox and remove alcohol from your system

The researchers…found that even if people walked as many as 20,000 steps a day, the health benefits continued to increase. They have not found an upper limit yet.

Because a lack of fiber brings on most cases of constipation in the diet, apple cider vinegar’s high concentration of pectin, a water-soluble dietary fiber, is believed to help improve digestion. Once the constipation has passed, pectin from ACV will help ensure the digestive system and colon are running smoothly.

Cranberries and pumpkin seeds can improve prostate symptoms

The chest should neither expand nor collapse during proper inhalation or exhalation.

When you’re healthy you have 10,000 needs, but when you’re sick you only have 1

When you consume alcohol you need to detoxify it. Two of the main enzymes are ADH and ALDH. Both require NAD as a cofactor, thus b3 is great to supplement. Another option: EAT CHEESE which massively stimulated both of those enzymes. The French get it.

Puzzlingly though, despite facing an increased risk of skin cancer, people who are exposed to lots of sun appear to have longer life expectancies, on average, than sun avoiders.

Health and fitness learnings for February: “There’s concrete evidence that meditation calms your brain similar to valium”

They buried the lede on this new study. It’s not that exercise beats out SSRIs for depression treatment, but that *just* dancing has the largest effect of *any treatment* for depression.

The right brain is in charge of present-moment awareness, and this is the part of the brain that meditation takes to the gym. Essentially, the longer we meditate, the more we’re able to balance the right and left hemispheres of the brain. The result of this is more attention, awareness, and computing power for the task at hand.

While aerobic exercise elevates neurotransmitters, creates new blood vessels that pipe in growth factors, and spawns new cells, complex activities put all that material to use by strengthening and expanding networks. The more complex the movements, the more complex the synaptic connections. And even though these circuits are created through movement, they can be recruited by other areas and used for thinking. This is why learning how to play the piano makes it easier for kids to learn math.

Now you know how exercise improves learning on three levels: first, it optimizes your mind-set to improve alertness, attention, and motivation; second, it prepares and encourages nerve cells to bind to one another, which is the cellular basis for logging in new information; and third, it spurs the development of new nerve cells from stem cells in the hippocampus.

Of the six areas that the FitnessGram measures, two seem to be particularly important in relation to academic performance. “Body mass index and aerobic fitness really stuck out in our regression equation,” Castelli says. “They were the most significant contributors. I was really surprised it was that clear-cut

Paleolithic man had to walk five to ten miles on an average day, just to be able to eat.

I think the most interesting part of the paper is the finding that walking improves creativity not due to environmental stimulation, but due to walking itself. Whether outdoors or on a treadmill, walking improved the generation of novel and appropriate ideas. Surprisingly, this effect extends to sitting after a walk

PeterAttiaMD: …his physical training program gives him a great VO2 max, his topical treatments give him much-better-than-his-genetics hair and skin, and his NAD+ precursor supplementation improves his rate of DNA repair.

Since at least the time of peripatetic Greek philosophers, many other writers have discovered a deep, intuitive connection between walking, thinking, and writing. (In fact, Adam Gopnik wrote about walking in The New Yorker just two weeks ago.) “How vain it is to sit down to write when you have not stood up to live!” Henry David Thoreau penned in his journal. “Methinks that the moment my legs begin to move, my thoughts begin to flow.” Thomas DeQuincey has calculated that William Wordsworth—whose poetry is filled with tramps up mountains, through forests, and along public roads—walked as many as a hundred and eighty thousand miles in his lifetime, which comes to an average of six and a half miles a day starting from age five

New study found that tea consumption is associated with attenuation of biological aging.
People who consistently drank >4 cups a day aged 40% slower than those who drank none.

Some studies suggest that people who cook more often, rather than get take-out, have an overall healthier diet. These studies also show that restaurant meals typically contain higher amounts of sodium, saturated fat, total fat, and overall calories than home-cooked meals

Health and fitness learnings for December: Eat more cheese, meat, and beans to fill “dopamine pool”

I’m publishing a list of the different health and fitness notes that I accumulated over the course of the month. Here’s November.

A week of sleep deprivation can lead to profound insulin resistance

Activity — staying physically and mentally active — is most powerful cure against diabetes

To increase water in your “dopamine pool”: Eat more cheese, meat, beans (Huberman)

Sizzling Sunlight: Bask in both morning and evening sunlight. Even if it’s cloudy and cold. It’s not just about Vitamin D; it’s about regulating your natural circadian rhythms

Dark chocolate is good for leaky gut (Ben Greenfield)

Cold Plunge Mornings: A lot of people have “mental battles” in the morning and low energy but the cold plunge does the trick – after three minutes, there’s a rush of endorphins happening enabling you to train right after

The average American goes their entire life without fasting for a day.
Kind of wild to think about. Every single day for their entire life, food goes in. This was certainly not true for our primal ancestors and I struggle to think we were meant to operate this way. I still remember waking up the morning after my first fast and thinking the entire nutritional system was a scam. Constantly told we had to eat breakfast, eat 3 square meals per day, etc. Merely a marketing ploy (@DickieBush)

“By looking at sunlight through a window, it’s 50, five zero, times less effective than if that window were to be open.” – @hubermanlab
(This is because windows filter out wavelengths of blue light)

When body composition is considered more precisely, fat mass increases mortality and fat-free mass decreases mortality (Chris Masterjohn)

Positive social connections and good social interactions are number one predictor of longevity (IG prof)

All human studies included in the review were randomized controlled trials mainly conducted in high- to middle-income countries which highlighted that both oral and topical collagen supplements help to delay the aging process, with no differences arising between the two types of collagen. The evidence from the reviewed studies suggested that both collagen supplements improve skin moisture, elasticity, and hydration when orally administered. Additionally, collagen reduces the wrinkling and roughness of the skin, and existing studies have not found any side effects of its oral supplements. (paper)

And even when I’m intently concentrating on my computer, it’s somehow nice to be outside—and, yes, it seems to have made my resting heart rate go down. (Stephen Wolfram)

Health and fitness learnings for November: the many benefits of HIIT

Every month, I try to collect interesting health related advice, facts, and stories to remind myself of what’s important / what can be improved / what can be turned into a useful health habit.

Here’s November:

Generally: patients with profound insulin resistance tend to respond best to low-carb restriction (source)

Shimiken exercises 90 minutes a day, four days a week, focusing on heavy weight lifting and deep squats, which he says not only help his thrusts but also build up testosterone (source)

Great thread on creatine: https://threadreaderapp.com/thread/1720093644051669028.html

Several nights of sleep restriction can throw off blood glucose levels, impair energy production, and disrupt natural body temperature rhythms. However, incorporating high-intensity interval training during this sleep-restricted period can counteract these effects. (source: think it’s a Rhonda Patrick podcast)

HIIT increases testosterone levels significantly more than steady-state cardio (source)

The chest should neither expand nor collapse during proper inhalation or exhalation. (source: The Naked Voice)

At least three times a week, Clark uses a sauna for 20 minutes before a cold shower. While working, she eats 16 ounces of vegetables a day, a mix of raw celery, radishes, carrots, peppers, and blanched broccoli along with a salad or soup (source)

I never wake up out of hunger – but frequently do out of eating the wrong or too much food. Hard to resist though. (source: a tweet, I think)

Mouthwash is the biggest dental scam. Kills your oral microbiota. Avoid (source)
