Having love in your life might just save you from the flu. A recent study showed that a five-minute episode of feeling genuine care or compassion enhanced the whole immune system, causing a gradual increase in the release of immunoglobulin A (IgA), your body’s natural antibody against colds, flu and other invading germs.
Even watching movies about love, petting an animal and practicing selfless service for others has been shown to increase levels of IgA.
