Feel happy, and get less colds?

Did you know that simply being happy can help boost your immunity? A new study supports previous research linking happy feelings to higher immunity, showing patients experiencing positive emotions were less likely to catch the cold virus they were exposed to than patients who were feeling negative emotions. And if the happy patients did catch the cold, they showed fewer symptoms.

This news, combined with earlier news that being happy protects your body from stressors that lead to heart disease, makes it obvious that our moods and emotions are something we need to start taking seriously as a factor in overall health.
