Neurons are chemical factories and if you think too hard for a prolonged period of time, the chemical balance of parts of them seems to be affected. It feels like they are inflamed.
I not only take breaks throughout the day, I even take breaks for weeks or months, when I feel, it is needed (and I can afford it).
It feels, like all the inflammations have to heal first. And then I am back to my old efficiency.
@djlink
I don't need and don't want to think about any related problems at my break time. After the healing period, everything is sorted out by itself.
But sadly, many people can not afford it or don't dare it, because they fear to lose or miss something. Or have the feeling of being irreplaceable.
And that leads to chronic mental blocks.
Just my observations.
