Not a woo woo.
As for adrenal-tyroid connection:
Excess cortisol leads (chronically) to less TSH which means less T3 (this also rises rT3). If cortisol is chronically elevated, lower thyroid hormones are seen as body stress which further amplifes cortisol secretion. This depletes adrenals of Vitamin C which is secreted in parallel with adrenalin and is also used to make it. This in turn further diminish your immune system as white blood cells need constant supply of C to fight infections. This in turn leads to chronic infections, increased xenobiotic metabolism (hence liver suffers), decreased dopamine synthesis as vitamin C is needed for it, reduced wound heali healing etc...
Its all connected, and while body can tollerate short times of duration stress and even thrive on it (hormesis) longer insults gradually destroys destroy you.
Or something like that.... :) Inform yourself about HPAT axis
