What hormone causes stress? The primary hormone responsible for stress is cortisol. Often referred to as the "stress hormone," cortisol is released by the adrenal glands in response to stressful situations as part of the body's fight-or-flight response. While cortisol plays a vital role in helping the body respond to immediate challenges, chronic elevation of this hormone due to ongoing stress can negatively affect physical and mental health. High cortisol levels over time can lead to anxiety, sleep issues, weight gain, and weakened immunity. Understanding how stress hormones work is an important step toward managing their impact. If you’re experiencing persistent stress symptoms, it’s wise to consult a mental health professional.
