Hypothalamus

Digging through old emails and found this about the hypothalamus:

One of its most important functions is connecting the nervous system to the endocrine system -the endocrine system being the organs that dump hormones directly into the bloodstream to then be carried to other organs.

"The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviors, thirst, fatigue, sleep, and circadian rhythms."

"The hypothalamus is responsive to:

Light: daylength and photoperiod for regulating circadian and seasonal rhythms
Olfactory stimuli, including pheromones
Steroids, including gonadal steroids and corticosteroids
Neurally transmitted information arising in particular from the heart, the stomach, and the reproductive tract
Autonomic inputs
Blood-borne stimuli, including leptin, ghrelin, angiotensin, insulin, pituitary hormones, cytokines, plasma concentrations of glucose and osmolarity etc.
Stress
Invading microorganisms by increasing body temperature, resetting the body's thermostat upward."

A notable characteristic of the hypothalamus is that it has specialized segments that effectively lack a blood/brain barrier. This is to allow certain hormones -mostly peptides- to actually reach the hypothalamus.

The hypothalamus is particularly responsive to steroids.

The hypothalamus is critical to "defensive behavior" -it has a big part in controlling how people react to perceived threats, at least of the predatory sort.

I infer therefore that the hypothalamus is particularly vulnerable to infection and irregularities as a result would have a dramatic influence on body temperature, everything to do with sleep/tiredness, and everything to do with eating/sleeping. This probably has to do with a lot of the weirdness with sleep cycles and the like that we've had, and that have been slowly getting better.

What I am getting out of it is that circulatory health will have a big (disproportionate) impact on it. Blood health has been a big thing we have worked on.

I don't know where to go with that, but I wanted tea to support my kidneys. I don't want to do watermelon yet, but I am still looking for ways to fix my bloat and ....kidneys, lungs and a lot of things are directly tied to blood and circulatory health.
