The course includes lessons on pathogens, the body's defenses, antimicrobials, vaccines, diseases, lifestyle risk factors, drugs, review, and tests.

Learning Goals

Understanding stress effects on the body, and the difference between short-term (acute) and long-term (chronic) stress is important.
The negative effects of insufficient sleep need to be understood.
The benefits of exercise on overall health should be recognized.

Recap- Communicable and Noncommunicable Diseases

Key takeaway: Differentiate between communicable and noncommunicable diseases.

Recap - Risk Factors

Identifying two cancer risk factors is required.
Listing diseases where stress is a risk factor is necessary.

Stress

Discussion on the concept of stress and its impact
Identifying personal stressors.
Understanding the different sources of stress: various examples illustrated through images, such as public speaking, athletic competition, or academic pressures.
The body's physiological fight or flight response during stress.
The body's chemical response to stress (adrenaline and cortisol) and resulting physiological changes.

Stress (Continued)

Different types of stress: short-term (acute) and long-term (chronic).
Discussing how short-term stress can be beneficial in certain situations but chronic stress is detrimental to health.
Chronic stress triggers and potential results: social issues, financial problems, illnesses, and mindsets as examples.
Short-term stress examples include public speaking, writing a test, and participating in a sport.

Stress (Continued).

The impact of chronic stress on physical and mental health.
Relationships between stress, poor sleep, memory, mood, emotions, unhealthy coping mechanisms.
Diagram illustrating the interconnectedness of stress, sleep, emotions, unhealthy coping, and physical health indicators such as blood pressure, immune function, and digestive system.

Sleep

Understanding the amount of sleep needed at different ages (newborns, infants, toddlers, preschoolers, school-age children, teenagers, young adults, adults, seniors).
The importance of sleep for growth, tissue repair, and brain function.
Sleep is crucial for processing information and forming new connections within the brain.
Insufficient sleep leads to physical and mental health issues.
