When you hit the runner’s wall, your body is actually now running on emergency fuel that’s close to being depleted. Imagine being a car and you’re close to running out of batteries. The first thing that shuts down is the car’s computer box.
A similar thing happens to runners: as your body goes into desperation mode trying to regulate the little amount of glucose left, your brain completely shuts down. This is a coping mechanism that results in low brain function which in turn creates feelings and thoughts of negativity.
Not only this, while continuously hitting the runner’s wall, but your decision-making also gets impaired to the point of clouded. Sometimes, it also causes hallucinations but very rarely.
Hitting the runner’s wall basically impacts your whole cognitive function. Emotionally, you’ll feel less motivated as you can’t even concentrate on the task at hand.
