Happiness can be an elusive state. Philosophers, theologians, psychologists, and even economists have long sought to define it. And since the 1990s, a whole branch of psychology—positive psychology—has been dedicated to pinning down and propagating the science of merry bliss. More than simply positive mood, happiness is a state of well-being that encompasses living a good life, one with a sense of meaning and deep contentment.
A growing body of research also suggests that happiness can improve your physical health; feelings of positivity and fulfillment seem to benefit cardiovascular health, the immune system, inflammation levels, and blood pressure, among other things. Happiness has even been linked to a longer lifespan as well as a higher quality of life and well-being.
Attaining happiness is a global pursuit. Researchers find that people from every corner of the world rate happiness more important than other desirable personal outcomes, such as obtaining wealth, acquiring material goods, and getting into heaven.
