Vagus activation by Cold Face Test reduces acute psychosocial stress responses

Scientific Reports, 2022
Chronic stress is linked to dysregulations of the two major stress pathways—the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis, which could for example result from maladaptive responses to repeated acute stress.
