Have you ever been so mentally drained that even choosing breakfast cereal felt impossible? It’s not just that you’re being indecisive. It’s decision fatigue, and it’s your nervous system’s way of saying your nervous system capacity is running low.

Think of nervous system capacity like an internal energy bank account. Every decision, big or small, is a withdrawal. When that account is empty, even simple choices can feel like climbing a mountain. Your brain hits “insufficient funds,” and suddenly you’re overwhelmed.

In this Biology Behind It mini episode, Dr. Aimie responds to a listener  who shared his embarrassing moment of having to leave the grocery store because choosing cereal felt impossible! This question opens the door to understanding decision fatigue, neuroception, and why our survival system treats every choice as a potential threat.

You'll hear more on:

• Why every decision is a withdrawal from your capacity account
• Why your nervous system doesn't distinguish between small and big decisions
• What happens when your energy reserves can't meet the demands you're facing
• How attachment filters from early life determine which decisions drain more energy than others
• Why low energy triggers trauma biology and chronic functional freeze
• Practical strategies to reduce decision fatigue

Whether you're struggling with decision overwhelm or supporting someone experiencing these "adult meltdowns," this episode helps you understand why small decisions can feel impossible and gives you concrete tools to build your capacity back up.
