Several times per week, I now invest the time in using an “altitude machine”.
In the comfort of my office, this device intermittently simulates high altitude oxygen levels, then sea level altitude oxygen levels, while I sit calmly.
Why do I do this?
Several reasons – that I will share in this post, now and later.
At the forefront of my mind right now is something called “subclinical hypothyroidism”. For several months I have been guinea-pigging to test the affect of altered metabolic rate (as measured by my morning body temperature) – on my energy levels and a mild digestion challenge at appears at night.
I have altered my diet significantly – and have put on approximately 3kg – mostly of fat. My digestion has improve markedly, and my body temperature is up 1 degree Celsius (on average). My energy levels are better – but not at the levels of 10 years ago – ok that would be miraculous.
Why am I messing with this rather than go to a medic and get prescribed an anti-indigestion medication? Firstly because I espouse finding the causal processes that lead to an effect, rather than treating the effect. So I literally have to eat my own cooking.
That has led me on an interesting (for me) ride through the systems that make up my body. Why am I getting indigestion? After a few different theories and tests – my best theory at this time is that my stomach is producing less acid than it used to. This variation has led to the downstream theory that not only is my food not being digested as it ought – but that the changed pH now allows bacteria to live my small intestine that previously did not live there.
And they produce gas. Lots of it.
After lots of testing – involving taking HCL with Pepsin – hydrochloric acid in a tablet you can swallow – you get it pharmacies over the counter. It is a “digestive aid”. Taking this product resulted in my digestion and symptoms being improved. Good.
Now – why was my acid production dropping? This turned into a rabbit hole of adventure.
After several theories tested and discarded, my current is that a reduced activity in my thyroid, directly alters a great many other systems – including acid production for digestion.
There are a great many other factors that can alter our digestion – including the simplest which is that NOT allowing our bodies to drop out of FLIGHT/FLIGHT/FREEZE mode before eating – is the equivalent of trying to have lunch while being chased by a tiger – in terms of hormones. You may get the food into you – but you body will not deal with it very well. Generating stomach acid while you are “in danger” is not a high priority for our bodies. After a few years of such a habit we begin to see the manifestation of this habit.
Anyway back to the thyroid. If you do a search on “subclinical hypothyroidism” you will find something like this from WebMD:
“No symptoms or mild symptoms of hypothyroidism. Examples are fatigue, cold intolerance, consistent weight gain, depression, or memory problems. A mildly high thyroid-stimulating hormone (TSH) level. Some people with subclinical hypothyroidism may test positive for antithyroid antibodies.”
So do YOU have any of the symptoms of this a little bit hypothyroidism?
What if just some that depression that is happening in the world is related to us feeling a bit “crap”, so our thinking changes, our actions change, and hey – we then feel down for several reasons, not just because our thyroid is a bit slow.

Conclusions: Thyroid hormones and emotionality during high-altitude acclimatization are influenced by ethnicity, and social-isolation/fear-of-death influences freeT4.
