I recently came across a fascinating YouTube video that delves into the differences between serotonin and dopamine. In this video, the speaker explains the vital distinctions between these two neurotransmitters and how they affect our lives. The video can be found here.

The Neuroscience Behind Pleasure and Happiness

To provide some context, dopamine is the neurotransmitter responsible for learning and positive reinforcement, while serotonin is associated with contentment and satisfaction. These two neurotransmitters have different effects on our brains and ultimately our overall well-being.

The Role of Cortisol

Cortisol, the stress hormone, plays a crucial role in the balance between dopamine and serotonin. Chronic stress increases cortisol levels, which can lead to addiction and depression. Cortisol can down-regulate serotonin receptors, leading to a lack of serotonin and depression. In contrast, the combination of dopamine and cortisol can result in addiction.

Seven Key Differences Between Pleasure and Happiness

The video highlights seven essential differences between pleasure and happiness:

  1. Pleasure is short-term, while happiness is long-term.
  2. Pleasure is visceral, felt in the body, while happiness is ethereal, experienced above the neck.
  3. Pleasure is taken, while happiness is given.
  4. Pleasure is achieved alone, whereas happiness is achieved in social groups.
  5. Pleasure can be obtained with substances, while happiness cannot.
  6. The extremes of pleasure, such as substance abuse or addictive behaviors, can lead to addiction, whereas happiness is not addictive.
  7. Pleasure is linked to dopamine, while happiness is associated with serotonin.

These differences are critical in understanding how our actions and choices can either contribute to our happiness or lead us down a path of addiction and depression.

The Consequences of Seeking Pleasure over Happiness

The more pleasure we seek, the unhappier we become. This is because dopamine, an excitatory neurotransmitter, can lead to tolerance and addiction. On the other hand, serotonin, an inhibitory neurotransmitter, does not cause addiction or neuron death. Thus, it is essential to recognize the difference between seeking pleasure and pursuing happiness.

How This Knowledge Can Improve Our Lives

By understanding the distinct roles of serotonin and dopamine, we can make informed choices to enhance our well-being. We can prioritize activities that promote long-term happiness and contentment over short-lived pleasures. Furthermore, recognizing how chronic stress affects our neurotransmitters can motivate us to seek healthier coping mechanisms and stress reduction techniques.


In conclusion, this video provides valuable insights into the neuroscience behind pleasure and happiness. By understanding these key concepts, we can make informed decisions that lead to healthier, happier lives. I highly recommend watching this video to gain a deeper understanding of the complex interplay between serotonin, dopamine, and cortisol in our brains.
