Many things can affect your mood-diet, exercise, stress and even the weather. In your body, a brain chemical called serotonin can also affect your mood.


It is a neurotransmitter and is essential for how your brain transmits information throughout your body. It allows your body to regulate emotions, improve cognition and control the sleep cycle.If you suffer from

Low serotonin
, You may feel anxious, depressed, or have trouble falling asleep.

What is a neurotransmitter?

When your brain wants to send information somewhere in the body, it must transmit information between nerve cells (neurons) to achieve the desired effect.

Neurotransmitters transmit this information
, Your body has dozens of different types to regulate different functions. Serotonin is one of them, focusing on the key areas of mood, sleep, appetite and cognition.

The role of serotonin in mental health

When the level of serotonin in your body is low, it cannot effectively perform its neurotransmitter function. This makes it more difficult to regulate emotions: you may lose appetite, have trouble sleeping, or be irritable.Some doctors will prescribe

Selective serotonin reuptake inhibitor

(SSRIs) treat symptoms of depression by increasing the levels of serotonin in the brain; these drugs are the most commonly used antidepressants. Even if your serotonin levels are not abnormally low, SSRIs will increase the amount of serotonin available in the body.

How SSRI works

Generally, when your brain uses serotonin to complete the process of transmitting information, it will be absorbed by the brain before being metabolized.

SSRIs prevent the reabsorption of serotonin into neurons
, Increase the usable amount of the body and improve signal transmission. This helps to improve mood, regulate sleep, and even eliminate anxiety.

You may have too many good things

Just as too little serotonin can negatively affect your mood, too much serotonin can cause harm.

Serotonin syndrome

It is caused by excessive accumulation of serotonin in your body. Mild cases can cause diarrhea and nausea, but in severe cases it can cause fever, muscle stiffness, and seizures.

Like all chemicals in the body, serotonin must be regulated to achieve the desired effect: balanced mood, stable sleep cycle, etc.
