Health Questions

1. As WHO Defines Health

The World Health Organization (WHO) defines health as a full state of complete physical, mental, and social well-being, not just the absence of disease or disability.

2. What We Mean by Quality of Life

Quality of life refers to the real possibilities and the best that a person could have to make a decent life in specific identified areas.

3. What Determines a Person’s Lifestyle?

  1. Innate or acquired characteristics

  3. Social factors that influence the immediate environment
  4. Physical environment that influences lives

4. Aspects That Contribute to Poor Health

  • Consumption of snuff, alcohol, and other drugs
  • Poor dietary practices
  • Making little or no exercise
  • Inadequate hygiene

5. What Are Healthy Habits?

  • Eating right
  • Practicing proper and regular physical activity
  • Hygiene
  • Regular sleeping patterns and proper duration

6. Principles That Promote Physical Activity

  • Perception of competition: Feeling competent, that is safe and practical possibilities, motivated and encouraged to participate.
  • Fun: When the activity is fun and pleasurable.
  • Modeling: Imitation of behaviors of others (adults) that serve as a reference.
  • Strengthening: Repeating what is pleasant and avoiding the unpleasant.

7. What Are the Anatomical Curvatures of the Back?

  1. Cervical lordosis
  2. Dorsal or thoracic kyphosis
  3. Lumbar lordosis
  4. Sacral kyphosis

8. What Role Does the Spine Have?

  1. Holds the body and allows movement.
  2. Helps to maintain a stable center of gravity, both at rest and in motion.
  3. Protects the spinal cord in a wrapped stone.

Posture

9. Correct Posture for Standing and Walking

  • Place one foot on a low stool or box to ease the stand.
  • Release pressure on the lower back.
  • Shift your weight from one foot to another often.
  • Stand up straight and walk with your head erect.
  • To help relax muscles, let your arms hang while walking.
  • Wear shoes that give proper support to your feet and are comfortable; avoid high heels.

10. Correct Sitting Posture and Carriage

When sitting, choose the correct chair; make sure that it will not cause back pain or make it worse. It should allow you to sit comfortably with good posture, with the lumbar curve well supported, using pillows to strengthen support if necessary. Keep your head straight, feet flat on the floor, and knees at the same level as your hips. Adjust the height of the chair as needed; the forearms should be level with the work surface.

In any case, whether to carry a load, you must do so as close to the body as possible. Carrying the weight with extended arms can make your spine bear up to 10 times the weight you’re carrying. If the weight of the load is considerable, walk with your knees bent while transporting it. Do not lean over with your legs outstretched, and do not rotate while holding a weight on top.

  1. Load close to the body
  2. Do not bend over with straight legs

11. Effective Personal Hygiene and Proper Posture

Postural hygiene and ergonomics are effective in preventing back pain because their aim is to reduce the load on your back during everyday activities.

Nutrition

12. What Are Nutrients?

Nutrients are responsible for providing energy to the body. We find different types of nutrients, some of them needed in large amounts (carbohydrates, proteins, fats, water), and others in smaller doses (vitamins and minerals).

13. Roles of Carbohydrates in the Body

Providing energy to support the growth and maintenance of tissues (e.g., muscle).

14. Carbohydrates in Relation to Physical Activity

We can say that carbohydrates are the basic fuel during exercise because exercise involves both short (anaerobic) and long-duration (aerobic) activities.

15. Functions of Fats in the Body

Energy reserves serve to isolate and protect the body from cold and beatings, transporting various substances, and being part of cells, tissues, and hormones.

16. When Do Fats Begin to Metabolize During Physical Activity?

Fats begin to metabolize (burn) in the presence of oxygen, i.e., during aerobic exercise of long duration.
