No condensation tho. Now it's 19.2C/21% but
everything still feels cold. Perhaps it is my
own immune system...

I'm currently at 15.6C and 42%RH inside and quite comfortable. At
19.2C, it's still a little cold, but with such low RH, you should be
feeling only slightly cold.

Are there any more tests save for the
temperature/humidity? The reason I ask is every
time I wake up I'm completely out of my head.
It improves rapidly tho but even after a really
good they the sleep and morning is the same,
awful. I Googled the symptoms and it matches
perfectly "brain fog" and hypoxia! But I'm only
at 15-25 MASL so that should be
impossible, right?

Does this only happen in the winter when you are burning firewood or
running a gas/propane/oil heater? If so, methinks you should test for
carbon monoxide. Buy or borrow a CO meter (not a smoke/CO detector)
and measure the CO accumulation:

The meters/monitors are slow to respond at low concentrations. The
sensor also has a limited life, usually 5 to 8 years depending on
chemistry and technology used:

I've found that my home CO level is fairly low (5-8 ppm) all night,
except for a big spike (25 ppm) just as the fire dies down in the
early morning. CO is produced by incomplete combustion.

A fingertip pulse oxymeter MIGHT show a lack of oxygen:

However, for CO poisoning, they're not a good indicator. I would get
one anyway in case your problem is caused by sleep apnea.

Nice, but please post smaller photos.

I have an assortment of felling axes, splitting axes, hatchets, mauls,
wedges, and hammers. I rarely use them, except for the hatchets,
which I use to chop up kindling.
