Dopamine is the brain’s “reward chemical.” It plays a major role in motivation, pleasure, and the ability to feel satisfaction from completing tasks. People who struggle with chronic procrastination often don’t get an internal reward--or dopamine boost--from finishing something, so they’re brain doesn’t naturally push them to do it. This is especially common in those with ADHD, but it’s not exclusive to it. Dopamine dysregulation can come as a result of depression, anxiety, chronic stress, burnout, sleep deprivation, or even a poor diet. Certain nutrient deficiencies like low iron or magnesium for example reduce dopamine production, leading to low energy and motivation.
