What is Cognitive load?

Cognitive load is how much your brain has to work at once, like trying to remember too many things at the same time.

Imagine you're playing with building blocks. If you have just a few blocks, it's easy to stack them up, that’s low cognitive load. But if someone gives you ten different colored blocks, and they all need to be stacked in a certain order, your brain has to think about each block one by one, that’s high cognitive load.

Your brain is like a busy little worker. If it has only one task to do, like counting how many blocks you have, it can focus all its energy on that job. But if it has to count, sort, and balance the blocks at the same time, it gets tired faster, just like when you're trying to solve a puzzle while someone is talking to you.

Sometimes, your brain can handle more tasks if things are simpler or more familiar. Like if you’ve played with those blocks before, your brain knows how they work, so stacking them becomes easier, that’s lower cognitive load.

So next time you feel confused or overwhelmed, think about your brain working hard like it's building a tower of blocks!
