What hormone causes stress? The main hormone responsible for stress is cortisol. Produced by the adrenal glands, cortisol is released in response to stress as part of the body’s natural fight-or-flight mechanism. It helps regulate blood pressure, metabolism, and energy levels during stressful situations. While short-term cortisol release is beneficial for handling immediate threats, consistently high levels due to chronic stress can negatively affect both physical and mental health—leading to issues like anxiety, fatigue, sleep disturbances, and even depression. If you feel overwhelmed by stress, seeking professional help can make a big difference.
