The most recent studies in health psychology are of particular interest to positive psychologists because they suggest that 

positive emotions may effect our health in ways that are essentially opposite from those for negative emotions.

there must be a balance between positive and negative experiences.

positive emotions cannot help during recovery, but do not appear to effect the basic functioning of the immune system before the onset of illness.

positive emotions are not connected to our basic biological make-up, but rather develop as a result of experience.

negative emotions are not nearly as damaging to our health as previously thought.
