If you’ve ever stared at your fridge at night and thought, “I can’t even decide what to eat,” this is for you.
It’s called decision fatigue.
Every choice you make during the day uses mental energy. What to wear. How to reply. What to prioritize. When to push. When to stop. By evening, that energy is low.
Research in psychology shows that decision-making becomes harder when the brain is tired. Not because you’re weak, but because you’ve been using it all day.
So small choices start to feel big. Motivation drops. Everything feels heavier.
That’s not failure. That’s being human.
Learning how to protect your mental energy is part of long-term wellbeing.
You don’t have to figure that out alone. www.upihealth.ca
