I know adrenal fatigue is a controversial topic as to whether it even exists, but I would like to temporarily suspend disbelief on that for this question.
We could just be a family of hardcore night owls, but whenever I see a list of the symptoms 3 generations of my family would seem to fit pretty squarely into having adrenal fatigue: a burst of energy in the evening and staying up waaaay too late regardless of consequences the following morning, can't get moving upon waking, needing a lot of coffee, ankle sprains from loose ligaments, responding well to adaptogens, etc.
I'm not sure about my dad, but my son and I do our best sleeping after the sun comes up in the morning, which most of the sleep experts claim to be out of sync with a healthy sleep/wake cycle. We get enough sleep, just not at the "right" times, and the days start really slow.
I thought it was just our family's bad habits about too much light and TV in the evening for the last 2 generations, and now we seem to have a third generation falling into the same thing regardless of evening light exposure, and I am wondering if this is a case of nature or nurture?
