PTSD

The Evolutionary Mismatch Human evolution occurred in a world defined by scarcity. Our ancestors survived by reflexively approaching pleasure and avoiding pain. They performed grueling work for minimal rewards. This biological hardwiring ensures we prioritize immediate energy conservation and quick caloric wins. Today, this same mechanism backfires. We live in a world of overabundance where the effort-to-reward ratio has collapsed, making productive tasks feel like insurmountable obstacles. The Dopamine Deficit State Dr. Anna Lembke explains that constant exposure to a fire hose of dopamine through scrolling, snacking, and streaming resets our joy set point. When we flood our brains with easy pleasure, we enter a dopamine deficit state to compensate. Our focus narrows, and we become consumed by the pursuit of the next hit just to reach baseline. In this state, leaving the couch to go to the gym feels like climbing Mount Everest because our neural chemistry is heavily weighted toward immediate comfort. The Myth of Dangerous Discomfort Modern culture promotes the idea that any distress is dangerous or potentially traumatic. We are told to prioritize relaxation and avoid anything that causes psychic friction. This narrative suggests that discomfort creates scars, leading to disorders like PTSD. However, the biological reality is the opposite. Avoiding all pain weakens our regulatory systems, leaving us more vulnerable to the very distress we fear. Rewiring Through Right-Sized Pain To regain motivation, we must lean into right-sized pain. This intentional discomfort triggers the body’s healing mechanisms and upregulates feel-good neurotransmitters like serotonin and endogenous opioids. By paying for our dopamine upfront through effort—just as we evolved to do—we restore the pleasure-pain balance. Reducing instantaneous pleasures allows the brain to reset, making simple, healthy habits feel accessible once again.
