Progesterone, by increasing oxidative efficiency, opposes this "angiogenic" (neovascularization) effect of estrogen 1 0 2While estrogen is usually highest at night, progesterone is lowest during the night 1 0 2Estrogen directly lowers the temperature, while progesterone raises the temperature 1 0 2Progesterone is probably the most perfect antiestrogenic hormone, and therefore an anti-stress and anti-aging hormone 1 0 2The nocturnal/stress hormones, especially prolactin and melatonin, make the retina more sensitive to light and more easily damaged 1 0 2Cytochrome oxidase is one of the enzymes damaged by stress and by blue light, and activated or restored by red light, thyroid, and progesterone 1 0 2Darkness increases TSH along with prolactin 1 0 1When progesterone is deficient, estrogen's effect is largely unopposed 1 0 2When both thyroid and progesterone are deficient, even fat cells synthesize estrogen 1 0 2Pregnenolone and progesterone deficiency causes memory loss, destabilization of nerve cells, failure of myelin formation, and excess cortisol synthesis 1 0 2
