Describe health and wellness using the ideas and concepts for each of the six dimensions of health: Physical health, Social health, Intellectual health, Environmental health, Emotional health, and Spiritual health
First, the 6 dimensions of health that you listed are actually dimensions of wellness, not health.
Health and wellness are closely related, but they are not the same thing. The simplest way to define health is to say that health is the absence of disease. That sounds pretty good, but it is possible to be healthy without being well (having a high degree of wellness).
Wellness at first sounds mystical in its definition. It is an overall state of being in optimal physical and mental health. After every definition I've read of wellness, my mind pictures some kind of Tibetan monk in the mountains with wind chimes in the background answering my questions with more questions. But the definition does make sense. A person could be perfectly healthy and still be quite depressed. They are healthy, but they have low emotional wellness. A person could be healthy, but they might really dislike their job. That would be low social wellness or occupational wellness. A person could be perfectly healthy, but eat poorly and never exercise. That would be poor physical wellness.
Wellness is definitely about maintaining healthy habits (diet and exercise) and having a positive mindset, but it is also about making choices based on risk factors. Risk factors come in all shapes and sizes, but they all have one thing in common -- they all increase a person's chance for illness and injury. Using your 6 dimensions of wellness, you could imagine a person who is in great health, eats right, has friends, loves their job, and is at peace with their spiritual life. By all accounts they are healthy and well. But perhaps that same person is an extreme mountain climber. That person has a hobby with a high risk factor for personal injury. To them, it might be worth the risk in order to be healthy and well. To other people, maybe not.
For your essay/paragraph, take the basic health/wellness concepts and apply them to various hypothetical people. Or if you feel comfortable, apply it to yourself. Write about why and how you are healthy (or not), and how well your life and habits fit into each of the wellness categories listed. Try to identify potential risk factors too.
