The provided knowledge contexts do not contain specific information about typical costs of cortisol training. Cortisol training generally refers to stress-regulation programs involving breathing exercises, biofeedback, supplements (e.g., ashwagandha, phosphatidylserine), or personalized coaching. Costs vary widely: from free apps to several hundred euros for professional guidance or lab tests (salivary cortisol day curves).

Consumers should be cautious of expensive programs promising rapid cortisol reduction, as the evidence for many interventions remains limited. Consulting a physician before investing in costly cortisol-focused products or services is advisable.
