Serotonin is a chemical involved in signalling between nerve cells in the body. But most people know serotonin as ‘the feel-good hormone’. This is not just good publicity, serotonin really does make you feel good. But not only does it improve your mood, it may also have an impact upon your health. Low serotonin levels are related to depression and poorer states of health. Serotonin also plays a role in:

  • sleep
  • bowel movements
  • blood clotting
  • wound healing
  • regulating anxiety
  • maintaining bone health.

So serotonin is pretty important. Serotonin levels can be directly influenced by your environment, but as shown above, serotonin can also have an impact upon other areas of your body. This is a potential mechanism by which a placebo effect could work – translating psychological input, into physical healing.

Note: This is a brief article and I hope to develop it and make it more scientifically grounded in future.
