This article will also cover why people in addiction recovery experience it and how long the symptoms typically last.

What Causes Emotional Flatlining?

Addiction, like mood disorders, affects dopamine in the rewards system. Every time someone with addiction uses narcotics, it creates high levels of dopamine. Eventually, the brain becomes used to these high levels of dopamine and stops producing dopamine on its own. When narcotics are withdrawn, the person is left with a very high tolerance for dopamine and a limited ability to produce it. As a result, their brain can no longer create dopamine in response to pleasure, and what it does produce has little effect due to the high dopamine tolerance.2 In addition to the dopamine deficit, another part of anhedonia is psychological. Life in active addiction has a lot of adrenaline. When this person enters recovery, they go from a life of constant adrenaline to almost none.

Six Holistic Ways to Treat Anhedonia

FAQ: Anhedonia in Addiction Recovery

Anhedonia is the loss of interest or pleasure in activities that once brought joy. Common signs include emotional numbness, low motivation, social withdrawal, and a lack of enjoyment in daily life.

Addiction changes how the brain processes reward. In recovery, the brain begins to rebalance, which can temporarily dull a person’s ability to feel pleasure. This phase is normal and often short-term.

Cognitive Behavioral Therapy (CBT), trauma-informed care, and experiential therapies—such as surf therapy or wilderness therapy—are effective. In some cases, Medication-Assisted Treatment (MAT) may also support recovery.

The timeline for anhedonia varies. Some individuals recover in weeks; others take months. With structured treatment and support, most people see steady improvement.

Exercise, quality sleep, good nutrition, and regular social connection can help restore the brain’s reward system. Mindfulness and time in nature can also improve mood and motivation.
