The Chemistry of Emotion: How Serotonin Affects Your Mood and Mental Health

If you’re suffering from sleep problems, mood disorders, depression, or anxiety, you could have a deeper problem—imbalanced serotonin levels. Serotonin, a neurotransmitter, carries messages between cells in your brain and throughout the body.

The primary role of serotonin is to regulate mood in your brain. Low serotonin levels in the brain are linked with depression, anxiety, and mental health disorders. On the other hand, higher serotonin levels—a ‘feel good’ chemical— is associated with good mood and mental well-being.       

Considering its impact on mental health and overall well-being, it’s essential to understand the causes of low levels and how to stabilize serotonin levels.

Here’s what you need to know.

The Brain-Mood Connection: How Serotonin Impacts Emotional Well-being

You’ll feel emotionally stable, happier, and calmer when your body produces enough serotonin. What’s more, enough serotonin helps you become more focused.

Optimum serotonin levels have the following impact on your emotional well-being.


  • Improved Mood: Serotonin controls your mood and activates feelings of happiness and well-being.


  • Helps to manage stress: It also enhances the body’s response to stress, reducing associated symptoms like depression.


  • Reducing anxiety: High serotonin levels promote a sense of calm.

Serotonin and Mental Health: Understanding the Chemistry of Emotion

Four main chemicals play a role in human mood and emotion; serotonin, adrenaline, dopamine, and oxytocin. It’s also important to understand the relationship between the brain and mood. 


Generally, the brain controls the release of chemicals (neurotransmitters) that communicate to other areas of the brain to stimulate or create a calming effect. Whenever there’s a chemical imbalance in the brain, the body produces too much or insufficient neurotransmitters.


If the imbalance is left untreated, you may develop a mood disorder or a mental health condition.

Managing Mood Swings: The Role of Serotonin in Emotional Regulation

Serotonin regulates mood by activating nerve cells in the brain responsible for mood regulation. When there’s enough serotonin in the brain, it binds to receptors in the nerve cells, stabilizing the mood and reducing feelings of anxiety and depression.


If you’ve low serotonin levels, you’re likely to experience the following:


  • Sleeping problems
  • Feeling bad about yourself
  • Memory problems
  • Decreased sexual desire


On the other hand, enough serotonin in your body enhances emotional stability, calmness, high energy levels, and focus.

From Depressions to Anxiety: How Imbalance of Serotonin levels Affect Emotional State

Insufficient serotonin levels in the brain can reduce the activity levels of nerve cells responsible for mood regulation. Unfortunately, the consequences of an imbalance of serotonin include depression and anxiety.


As a result, you may develop anxiety symptoms like nervousness, increased heart rate, sweating, and weakness. Low serotonin levels may also disrupt other bodily functions like sleep and appetite, resulting in depression and anxiety.
