Serotonin

What is serotonin?

Serotonin is a chemical substance that is produced and released by nerve cells. It is one of the so-called neurotransmitters that transmit signals between nerve cells. Serotonin has many functions in the body, for example:

• It regulates mood and emotional balance. A high serotonin level promotes positive feelings such as happiness, contentment and serenity. A low serotonin level can lead to depression, anxiety and aggression.
• It influences learning, memory and cognition. Serotonin helps to process, store and retrieve information. It also supports concentration and attention.
• It controls appetite and metabolism. Serotonin signals to the body when it is full and when it is hungry. It also regulates digestion and body temperature.
• It affects the cardiovascular system and blood pressure. Serotonin dilates or constricts the blood vessels as required. It also protects against blood clots and inflammation.

How does serotonin work in dogs?

Serotonin also plays an important role in the well-being of dogs. As in humans, serotonin levels depend on various factors, such as

• Diet: certain nutrients such as tryptophan, an amino acid, are necessary for the formation of serotonin. Tryptophan is found in protein-rich foods such as meat, fish, eggs and dairy products. Carbohydrates can also promote serotonin synthesis by transporting tryptophan to the brain.
• Exercise: Physical activity stimulates the release of serotonin and other happiness hormones such as endorphins. Exercise also improves blood flow to the brain and reduces stress.
• The environment: The environment in which a dog lives can influence its serotonin levels. Factors such as light, temperature, noise or social interactions can have a positive or negative effect. For example, sunlight can increase serotonin production, while darkness can decrease it.

What are the advantages and disadvantages of serotonin?

Serotonin has both advantages and disadvantages for dogs. A balanced serotonin level is important for a good quality of life. However, a lack or excess of serotonin can lead to problems.

The benefits of serotonin include:

• It promotes well-being and happiness in dogs. A happy dog is a healthy dog.
• It helps to cope with stress and anxiety. A relaxed dog is a calm dog.
• It improves the learning ability and behavior of dogs. A smart dog is an obedient dog.

The disadvantages of serotonin include:

• It can lead to side effects if administered in too high doses. For example, drugs that increase serotonin levels, such as antidepressants or painkillers, can lead to nausea, vomiting, diarrhea or seizures.
• It can lead to a life-threatening condition called serotonin syndrome if it interacts with other substances.
