According to Psychology Today: 

"Living a healthy life means making lifestyle choices that support your physical, mental, spiritual, and emotional well-being. Managing your health can be challenging at times; while one facet of your wellness demands more attention than others, you may end up struggling to maintain a good balance in other areas. To be of sound body, mind, and spirit, it’s important to pay attention to all aspects of health—your mental, emotional, and spiritual sides all play a role in your physical welfare, and vice versa. A state of optimal well-being means more than just the absence of disease or disorder; it also means having the resources to cope with problems and circumstances beyond your control and recover from difficult or troubling situations. This intersection between health and behavior can help you prevent or at least delay chronic illness, and steer you to make better decisions about your well-being."
