When the body is under stress, it triggers a complex response involving the hypothalamic-pituitary-adrenal (HPA) axis. This response releases stress hormones like cortisol and adrenaline. Elevated cortisol levels, in particular, can inhibit the synthesis and release of serotonin by decreasing the availability of its precursor, tryptophan.
