Stress: An Overview
Stress, a biological response to demanding situations, triggers the 'fight or flight' response, releasing cortisol and adrenaline, preparing the body to act quickly.
Acute vs Chronic Stress
Acute stress is short-term and situation-specific, often motivating. Chronic stress, however, persists over time, leading to health issues like heart disease and depression.
Stress and Memory
Stress can enhance the formation of certain memories but impairs retrieval. Chronic stress damages the hippocampus, inhibiting the creation of new memories.
Stress-Induced Genetic Change
Surprisingly, stress can alter gene expression, potentially affecting future generations through epigenetic changes. These can influence the stress responses of descendants.
Gut-Brain Stress Link
Stress affects gut microbiota composition, impacting digestive health and potentially contributing to psychiatric disorders due to the gut-brain axis connection.
Social Support Buffer
A lesser-known fact: social support can buffer against stress effects, reducing cardiovascular risks and improving immune function through oxytocin release.
Stress Management Techniques
Effective stress management includes mindfulness, exercise, and cognitive-behavioral strategies. Regular practice can rewire the brain to reduce stress reactivity.
