Stress Physiology and Health
Stress physiology examines how the body responds to stressors through complex biological processes involving the nervous, endocrine, and immune systems. These responses, such as the release of cortisol and adrenaline, prepare the body to handle challenges but can negatively impact health if prolonged. Chronic stress is linked to various health problems, including cardiovascular disease, weakened immunity, and mental health disorders, highlighting the importance of managing stress for overall well-being.

💡 Key Takeaways
- Understand how the nervous, endocrine, and immune systems coordinate the body's response to stress.
- Describe the roles of cortisol and adrenaline in the stress response and how they affect the body.
- Explain the difference between acute and chronic stress and how prolonged activation can impact health.
- Identify lifestyle and behavioral factors that influence stress physiology and health outcomes.
❓ Frequently Asked Questions
What is stress physiology?
The study of how the body responds to stressors through nervous, endocrine, and immune system processes, including the release of stress hormones to prepare for challenges.
Which body systems are primarily involved in the stress response?
The nervous system (brain and nerves), the endocrine system (hormones via the HPA and SAM axes), and the immune system (inflammation and immune regulation).
What hormones are commonly released during stress, and what do they do?
Cortisol and adrenaline (epinephrine) are released to boost energy and alertness; norepinephrine may also rise to support immediate responses.
How can prolonged stress affect health?
Chronic stress can suppress immunity, raise blood pressure and metabolic risk, and disrupt sleep and mood.
