WELLNESS
“To have a sound body, one
must have a sound mind”
Plato
1) Good health is Physical, Mental, and Social
well-being, and not just the absence of
disease.
2)Draw a wellness triangle.

S
3) Wellness is positive state of health, an
overall state of well-being, the total person.
1) Promote health
2) Prevent disease
3) Responsible for yourself
4) Mentally healthy people
satisfying relationships
feel good about themselves
behave in healthful ways
good goal
5) Holistic health: Dealing with the total person.
Define negative and positive behavior and list 2
behaviors of each.
6) Negative behavior is: A stimulus that has a
negative result. A behavior that decreases your
health level.
Physical
Mental
1) Drugs
1. Stress
2) Not eating right 2. Addictions
Social
1. Harassment/bully
2. attitude
7) Positive behavior is: A stimulus that has a
positive outcome on your health
Physical
1. Eating well
2. Exercising
Mental
1. low stress
2. attitudes
Social
1. Try new things
2. Join club or team
8) The three levels of health that concern us:
1) Personal: Things we do for ourselves
2) Community: Programs, protections, rules
that the community sets for us
3) World-wide: Same as #2 but on a larger scale
9) Wellness Continuum: A sliding scale of that state
of one’s health. It goes between poor and good.
10) The US focuses on treatment not prevention.
11) Health survey- 1-12 in each section. Give yourself 1 pt.
for each answer you feel is true. Score in area
separately. Put score on wellness triangle.
