Understanding the Stress Response and Its Effects
The Stress Response
The stress response allows us to get ready for vigorous activity and is perfectly normal. All the physiological responses involved in stress are catabolic; they help mobilize the body’s energy stores. The sympathetic branch of the autonomic nervous system (ANS) becomes active, causing the adrenal medulla to secrete epinephrine (adrenaline), resulting in:
- Increased glucose availability and metabolism (energy stores become available)
- Increased cardiovascular output and blood flow

Kant adopted the idea of the social contract, drawing inspiration from Rousseau’s works, and integrated it into his practical philosophy. This marked a significant advancement in contractarian thought. Kant’s concept differs substantially from Hobbes’s.
