The stress response involves the hypothalamic-pituitary-adrenal axis and the autonomic nervous system. Biofeedback allows training the regulation of this response.

Chronic stress is associated with changes in heart rate variability (HRV), muscle tension (EMG) and skin conductance (GSR). Biofeedback gives the user real-time information on these signals, facilitating learning of self-regulation strategies. For evidence levels by condition (anxiety, pain, etc.), see Studies & Certification and the related therapy stress page.
The stress response mobilises the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system; recovery often involves the parasympathetic branch and metrics such as heart rate variability (HRV), discussed in the literature as regulation proxies.
Biofeedback does not change a diagnosis directly; it offers guided practice of regulation. For the vagus nerve and breathing, see Vagus nerve regulation and Heart rate variability training. Evidence by condition in Studies & Certification.
Understanding the stress axis helps set expectations: training autonomic regulation is not the same as investigating organic or psychiatric causes when your clinician suspects them.
