How Does Procrastination Show Up In Our Brain?

Introduction

Have you ever planned of doing homework but kept putting it off and ended up never doing it? This is one of the many ways procrastination can show up in our lives. I personally procrastinate a lot and it is something I am doing my best to overcome. Besides the effects of procrastination that we are able to see such as a lack of performance in tests, there are also internal effects that should be brought to our attention.

What In The Brain Causes Procrastination?

We all know what procrastination is but how does it happen? As stated by Insight Psychology, it involves the our limbic system and prefrontal cortex. Insight Psychology explains that, "When faced with an unpleasant or challenging task, the limbic system seeks to avoid discomfort." The amygdala activates during these challenging tasks and leads us towards instant relief. It helps us avoid tasks and we instead look for comfort in an activity we enjoy. Furthermore, when we do engage with a task more enjoyable, dopamine will be release and reinforce our decision.

Based on Insight Psychology, the prefrontal cortex, which has a responsibility for decision-making, tries to go against our limbic system and fight the avoidance. However, the prefrontal cortex has a hard time and this leads to a constant fight between the two. This is a reason why procrastination is able to occur because our prefrontal cortex is not able to successfully interfere with it.

The Negative Effects Of Procrastination

According to Insight Psychology there are 3 ways the brain can be negatively affects:

1. Neural Pathways and Habits - "Repeated procrastination strengthens neural pathways associated with avoidance, making it easier to delay tasks in the future. Conversely, pathways for discipline and focus weaken."

2. Gray Matter Reduction in the Prefrontal Cortex - "Studies show that chronic procrastination may be linked to reduced gray matter in the prefrontal cortex, affecting decision-making and impulse control."

3. Increased Stress Hormones - "Frequent procrastination raises cortisol levels, the body’s stress hormone, which can impair memory, focus, and overall mental health."

Conclusion

Procrastination can show up in our brain in our limbic system and prefrontal cortex. It can harm our brain in ways such as our neural pathways, reduction of gray matter, and increase stress hormones. Most importantly procrastination hurts our well being because it causes us to ignore duties we know we have to do. Just like in past blog posts, our prefrontal cortex needs our strength to fight against procrastination so we can all live our lives stress free. Without having to worry about getting tasks done and instead getting them done, will assist in making our life so much easier! Remember you are not alone!
