What are the functions of Serotonin?

    • Mood – It is best known for its positive effects on mood, it is believed that low levels are associated with depression and anxiety. Mind altering drugs such as ecstasy and LSD cause a huge rise in its levels.
    • Sleep – It also plays an important role in controlling our circadian rhythm – our body’s internal clock. Serotonin levels are at its lowest while we sleep, and increase when we wake. Low levels will disrupt our sleep patterns.
    • Cognition -The serotonin receptors are also found in the brain regions involved in learning and memory.
    • Bowel function – The majority of serotonin travels to the lining of the intestines and stomach. When we eat, serotonin is released and controls the contractions that push food through the digestive tract. An imbalance of serotonin has been linked to constipation, irritable bowel syndrome (IBS) and diarrhea.
    • Sexual function – Low levels can increase our sexual libido, whereas high levels can decrease our libido.
    • Blood clotting – Clotting of the blood is contributed by the serotonin levels. It is released by platelets when there is a wound, by narrowing the blood vessels, reducing blood flow and help blood clots to form.
    • Nausea – When you eat something that irritates your stomach, the gut produces more serotonin to flush out the toxins, resulting in nausea.
