Researchers Uncover Biology of Mental Fatigue

Researchers have been trying to understand why our brains get tired when we think too much.

They found that when we concentrate or make decisions, our brains use a lot of energy.

This can make us feel exhausted.

The study looked at different chemicals in the brain, like glucose and adenosine, to see how they affect our mental energy.

They also found that sleep is very important for the brain to recover.

Some people feel this tiredness more, especially those with conditions like long COVID or chronic fatigue syndrome.

The researchers hope this will help us understand and maybe even treat mental fatigue better in the future.
