Your Brain Is an Energy Powerhouse

Your brain may only make up about 2% of your body weight, but it uses roughly 20% of your body's energy at rest.

Even when you're sitting still, your brain is working nonstop—processing information, maintaining memories, controlling movement, regulating essential functions, and keeping billions of neurons communicating.

So while you may not feel like you're “doing” anything, your brain definitely is.

The next time you feel mentally exhausted after a long day of thinking, remember: your brain is one of the most energy-demanding organs in your body!
