Numerous chemicals and hormones impact how we think and function every day. These include dopamine, melatonin, and serotonin. We can't live without them, but an excess can be as dangerous as having too little. An overload of serotonin, for example, leads to serotonin syndrome and has serious consequences.


1. What is Serotonin Syndrome?

Serotonin syndrome is a dangerous reaction to a high concentration of serotonin in the body. Some scientists and historians have found references to what they believe is a similar affliction dating back almost 1,000 years, long before it was medically recognized. Serotonin syndrome can occur when the body produces too much serotonin, or when another factor stops the body from absorbing healthy amounts.
