What is creativity really?
From a scientific perspective, creativity is your ability to think of something original from connections made between pre-existing ideas in your brain.
These connections are controlled by neurotransmitters like adenosine, which alerts your brain when you’re running out of energy and reacts by slowing down the connections made between neurons by binding to adenosine receptors.
Adenosine is kind of like your brain’s battery status monitor. Once your energy levels get low, adenosine alerts your brain and starts to slow down brain functioning.
This is why after a few hours of intense work, you begin to feel tired, like your brain has run out of juice.
The only way to recharge it is to take a break; unless, you’ve got a secret weapon handy.
