1) Health can be defined as the physical, mental and social well-being of an individual, not just the absence of disease. The WHO defines health as a state of complete physical, mental and social well-being. 2) Physical health involves good nutrition, exercise and rest, while mental health refers to emotional and cognitive well-being. 3) Many communities have rituals and practices related to birth, death and caring for the ill/dying based on their cultural and religious beliefs. Understanding these differences is important for healthcare practitioners.
