Stress Impairs Self-Control

Why willpower fails under stress—it's neurobiology, not weakness.

What the evidence says

• Stress dampens prefrontal cortex activity¹
• Prefrontal cortex governs deliberate decision-making and self-regulation¹
• Simultaneously hyperactivates limbic/reward circuitry¹
• Result: automatic behaviors override conscious intentions¹
• Reduced self-regulation capacity despite wanting to make good choices¹
