Serotonin is primarily responsible for mental health. It is a neurotransmitter that helps to reduce anxiety, regulate sleep, regulate appetite, and regulates mood.

Tryptophan is one of the essential amino acids that makes serotonin, it is important to eat a tryptophan-rich diet to maintain a healthy mental status. Usually, foods like nuts, cheese, red meat has good amount of tryptophan. If the diet is deficient in tryptophan, it eventually leads to a decrease in serotonin levels resulting in mood disorders such as anxiety, depression, mood swings, disturbed sleep, improper digestion, over or less eating, etc. When serotonin levels are normal, we feel happy, healthy, calm, focused, less anxious, and emotionally stable. And when Serotonin levels increase one may experience shivering, heavy sweating, confusion, restlessness, headache, high blood pressure, high fever, unconsciousness, seizures, irregular heartbeats, etc. A good amount of exposure to Sunlight, regular exercise, a wholesome healthy diet, and meditation helps to boost serotonin levels in our body.
