There is no consensus around a single definition of wellness, but there is general agreement that at minimum, wellness includes the presence of positive emotions and moods (e.g. contentment, happiness), the absence or lack  of negative emotions (e.g., depression, anxiety), satisfaction with life, fulfillment and positive functioning.  In simple terms, wellness can be described as judging life positively and feeling good. For public health purposes, physical wellness (e.g. feeling very healthy and full of energy) is also viewed as critical to overall wellness. Researchers from different disciplines have examined different aspects of wellness that include the following⁶:

• Physical wellness.
• Economic wellness.
• Social wellness.
• Development and activity.
• Emotional wellness.
• Psychological wellness.
• Life satisfaction.
• Domain specific satisfaction.
• Engaging activities and work.
