- Experiencing a sudden drop in blood sugar due to starvation.

How does the human stress response differ from that of animals when considering anticipatory stress?
How does the human stress response differ from that of animals when considering anticipatory stress?
- Animals experience anticipatory stress to a greater extent because they rely on instinct.
- Humans can activate the stress response by merely contemplating future events, whereas animals generally react only to immediate threats. (correct)
- Humans do not experience anticipatory stress, as their cognitive functions are more developed.
- Animals and humans both react to future events to the same degree.
In the context of the body's response to stress, what is the primary role of glucocorticoids like cortisol?
In the context of the body's response to stress, what is the primary role of glucocorticoids like cortisol?
- To regulate metabolism and immune function during stress. (correct)
- To rapidly decrease heart rate and calm the individual down after a stressful event.
- To shut down non-essential bodily functions like digestion during acute stress.
- To immediately increase muscle strength and reaction time during a fight-or-flight response.

Study Notes
- Stress represents the body's biological response to challenges or perceived threats, which requires adaptation to maintain homeostasis
- Homeostasis is the body's state of physiological balance
Types of Stressors
- Physical stressors involve immediate threats like injury, starvation, or extreme temperatures
- Chronic physical challenges include long-term threats like drought or persistent hunger
- Psychological and social stressors are unique to humans and primates, including financial worries, relationship problems, job pressures, or social status concerns
The Body's Response to Stress
- The Fight-or-Flight response is the body's natural reaction to threats, increasing heart rate, mobilizing energy, and heightening alertness
- Glucocorticoids are hormones like cortisol released to regulate metabolism and immune function when stressed
- Short-term stress can aid survival, while prolonged stress can cause health issues
Anticipatory Stress
- Humans can activate the stress response by thinking about future events, unlike animals that only react to immediate threats
- Students worrying about exams can experience stress symptoms even before the actual test
Health Consequences of Stress
- Cardiovascular effects of chronic stress can lead to high blood pressure and heart disease
- Metabolic effects of prolonged stress disrupts blood sugar levels and increases the risk of diabetes
- Immune system suppression is a consequence of chronic stress, which weakens the immune system and increases the risk of infections
- Cognitive impairment results from stress affecting memory, learning, and emotional regulation
The Modern Stress Burden
- Unlike animals that experience short bursts of stress, humans prolong the stress response by worrying about social, economic, and personal issues
- Overactivation of stress systems leads to stress-related diseases
