The mental load in the brain, what does it give? —

Making an appointment with the pediatrician, picking up a package, vacuuming, sending a last email… It’s a succession of tasks which, as they are carried out, accumulate one after the other. .

If these long lists rinse you, they also exhaust your brain, and more precisely, your prefrontal cortex. It is the conductor of the gray matter, it manages the higher cognitive functions, and among them, the short-term memory.

The exhaustion of managing everything

The memory can store up to seven pieces of information at the same time and will prioritize them in order of importance before processing them. This is how you can both buy the bread AND think about filing your tax return.

The problem is when these tasks compete at the same time. So try talking on the phone while sending an email for example… Even Kali, the Hindu goddess with many arms, couldn’t do it!

A sleep necessary to evacuate

In these cases, the brain overheats, this is called cognitive overload. To avoid this, the brain regularly cleans up at a very specific time: during your sleep.

Each night, your memory will erase from its list the tasks that have become useless and thus make room for the following ones. Hence the importance of sleeping well: without quality sleep, no cleaning, and without cleaning, beware of overheating! So remember, sleeping is never wasted time.
