Western medicine is still in its honeymoon period with the mind-body connection. Many cultures have understood this connection for hundreds — if not thousands — of years, but here in the West, we’ve been slow to come around.

People with generally positive outlooks show greater resistance to developing colds than do individuals who rarely revel in upbeat feelings, a new investigation finds.

Frequently basking in positive emotions defends against colds regardless of how often one experiences negative emotions, say psychologist Sheldon Cohen of Carnegie Mellon University in Pittsburgh and his colleagues. They suspect that positive emotions stimulate symptom-fighting substances.

“We need to take more seriously the possibility that a positive emotional style is a major player in disease risk,” Cohen says.

The exact mechanism(s) of how this works have yet to be fully understood, but I can guarantee you one thing: as soon as it is understood, pharmaceutical companies will patent, bottle, and sell artificial “positive moods” as immuno-boosters.

The good news is that you already have direct access to your emotions even though you may believe that your mood is pre-ordained by genetics. Despite popular belief, this isn’t true. Thankfully, there’s a host of scientific studies that have shown this to be the case.

The truth is that your attitude is not determined by how healthy, how wealthy, or how attractive you are. Your mood is determined solely by your attitude. If you can adjust your attitude in spite of your hardships then you can adjust your mood. It’s easier said than done, but it can be done.

Or you can just wait for the happy pill.
