What does stress really do to our bodies
From an elevated heart rate to weakened immunity, experts explain the hidden physical costs of chronic stress – and why our bodies aren’t built to stay on high alert

TL;DR
- The fight-or-flight response, triggered by adrenaline and cortisol, prepares the body for immediate challenges.
- Chronic stress prevents the body from returning to 'rest and digest' mode, impacting digestion, repair, and immune function.
- Long-term stress is linked to poorer immune function, increased risk of infections, obesity, depression, and neurodegenerative diseases.
- The physiological changes caused by stress can create a feedback loop, amplifying anxiety and impairing decision-making.
- While the body is designed to recover from stress, prolonged and enduring stressors can take a significant toll on health.
- Factors like trauma, learned resilience, and lifestyle choices influence an individual's tolerance to stress.
- Managing stress can involve techniques like regulated breathing, exercise, cognitive behavioural therapy (CBT), and mindfulness-based stress reduction.
- Addressing the root causes of stress and seeking help for chronic stress are crucial for well-being.
