Study Notes
Unit 4 - Preventive Health Behaviors - Greatest Hits
- Stress can cause diabetes, heart disease, high blood pressure, and obesity.
- Lack of exercise can lead to heart disease, diabetes, cancer, and obesity.
- Lack of sleep can cause depression, high blood pressure, diabetes, a weakened immune system, and poor memory. Sleep deprivation can also increase heart rate variability, increase the risk of heart disease, decrease reaction time, cause tremors, and aches. It can also negatively impact the immune system, resulting in symptoms like growth suppression, obesity risk, and decreased body temperature.
- Essential nutrients include protein (with 22 amino acids), supporting muscle, brain, and other tissue growth; carbohydrates, converting to glucose for immediate or stored energy; and fats for energy during starvation or deprivation, insulation, and vital organ protection.
- Micronutrients—vitamins and minerals—are essential to the body. Water-soluble vitamins are not easily stored (Vitamins B and C), while fat-soluble vitamins are stored in the liver and fatty tissues (Vitamins A, D, E, and K).
Stress
- Stress is the body's response to stimuli requiring adjustments to a changing environment.
- Change always initiates stress.
- Stressors are situations, events, or concepts, encompassing both internal factors (e.g., heart attack) and external factors (e.g., new job).
- Stressors trigger a "fight or flight" response in the body.
- Adrenaline is released into the bloodstream; blood vessels dilate, pupils dilate, saliva production decreases, heart rate increases, sweat increases, and respiratory rate increases.
How to Manage Stress
- Stressors are problems needing resolution or elimination.
- If stress is manageable, employ problem-solving methods.
- If stress is overwhelming, follow a 4-step plan:
- Stop - Pause the stress-inducing activity
- Breathe - Deep breaths to reduce physical tension
- Reflect - Identify the stressor and its root causes
- Choose - Select coping strategies to manage the stress
Essential Nutrients: Macronutrients
- Protein: Provides amino acids for building tissues.
- Carbohydrates: Convert into glucose for immediate or stored energy.
- Fats: Important energy source, essential for insulation, cell function, and organ protection.
Essential Nutrients: Micronutrients
- Vitamins & Minerals: Body cannot produce most vitamins and minerals, must obtain through food.
- Water-soluble: Not easily stored (Vitamins B and C).
- Fat-soluble: Stored in the liver (Vitamins A, D, E, and K).
Food Labels
- Food labels provide nutritional information.
- Calorie content, serving size, and percentages of daily values for various nutrients are key information on a food label.
