Psychological mood manager: Serotonin

Serotonin, often known as the "happy hormone," plays a truly important role in our well-being—and not just because it makes us feel more relaxed and balanced. This small but powerful molecule influences many areas of our mental and physical health, from our mood to our sleep to our social relationships.

One of serotonin's main functions is mood regulation. It helps us balance emotions, allowing us to feel calmer and more content. Perhaps you've noticed how good you feel on a sunny day or how relaxed you are after a delicious meal—this is exactly where serotonin comes in. It ensures that feelings like anxiety and stress don't overwhelm us and that we maintain inner balance.

But serotonin is also important for our sleep. It participates in the production of melatonin, the hormone that controls our sleep-wake cycle. When our serotonin levels are balanced, we sleep better and more restfully. This shows how closely our mental and physical state are linked. Our appetite is also influenced by serotonin. It helps us develop a feeling of satiety after eating, so we don't eat beyond our hunger. This balance is crucial for a healthy diet and general well-being. Serotonin also plays a role in our social life: It influences our trust, our willingness to cooperate, and how comfortable we feel in company. When serotonin is balanced, we often feel more relaxed and open in our interactions with others.

But what happens when the balance is disturbed? Low serotonin levels are often associated with mood swings such as depression and anxiety. Too much serotonin, in turn, can also lead to problems. Medications such as antidepressants target this issue by raising serotonin levels. Lifestyle factors such as regular exercise, sunlight, and a balanced diet can also naturally boost serotonin production.

Serotonin is therefore much more than just a "feel-good factor." It helps us feel more relaxed, balanced, and socially connected. Whether it's enjoying the moment or sleeping well at night, serotonin is one of our brain's most powerful helpers when it comes to emotional balance and well-being.
