Biological factors play an integral role in determining our stress responses.
- Genetics: Our genetic makeup can influence how we respond to stress. For instance, variations in genes associated with the stress hormone system can make some people more susceptible to stress (Manoliu et al., 2018).
- Energy Trade-offs: Our bodies make trade-offs between immediate needs and long-term survival. During stressful periods, resources may be diverted from long-term projects like growth and reproduction to immediate survival needs (Ellis et al., 2017).
- Personality-Temperament: Certain personality traits, such as neuroticism, are associated with higher perceived stress and poor stress-coping strategies (Lahey, 2009).
- Neuromodulators and Neurohormones: Stress responses involve complex interactions between neuromodulators (like serotonin) and neurohormones (like cortisol) that can influence mood, cognition, and physical health (Joëls et al., 2018).
- Metabolism, Detoxification, Immune Systems, Interoception: Metabolic, detoxification, and immune system function can influence and be influenced by stress. For instance, chronic stress can dysregulate immune function (Morey et al., 2015). Interoception, or our ability to sense our internal body state, can also modulate stress (Füstös et al., 2013).
- Psychological Factors and Stress: Psychological factors significantly impact how we perceive, interpret, and cope with stress.
- Safety, Skills, Connection: Feelings of safety, skill availability, and social connections can buffer against stress. For instance, having strong social support can promote resilience to stress (Southwick et al., 2016).
- Mindset: Our mindset towards stress can shape its impact. Viewing stress as a challenge rather than a threat can improve coping and outcomes (Crum et al., 2013).
- Working Memory: Stress can impair working memory, which in turn can exacerbate stress (Shields et al., 2016).
- Cognitive Reserve and Cognitive Load
- Social Factors and Stress: Our social environment can either buffer or amplify stress.
- Financial Security, ACES (Adverse Childhood Experiences), Identity, Community, Family: These factors can significantly influence stress levels. For instance, financial insecurity and adverse childhood experiences can contribute to chronic stress, while positive identity, supportive community, and family can buffer against stress (Hughes et al., 2017).
- Nutritional Factors and Stress: Nutrition can modulate our stress responses.
- Food Education, Self-Medicating Foods, Food Allergy & Sensitivities, Fatty Acids, Macro & Micronutrients, Microbiota, Sunlight-Nature, Antioxidant Status: These factors influence stress responses. For example, diets high in saturated fats can exacerbate stress responses, while diets rich in fruits, vegetables, lean proteins, and whole grains can buffer against stress (Michels et al., 2018).
- Other Central Factors: These factors interact with and influence all the other domains.
- Microbiome, Stress and Inflammation, Epigenetics & Transgenerations and Intersectional Trauma, Prenatal and Perinatal Circumstances, Social Barriers to Ability and Disability: These factors interplay with stress. For example, the gut microbiome can influence brain function and stress responses through the gut-brain axis (Foster et al., 2017).
All these factors, in the context of complex adaptive systems and emergent allostasis, interact and influence each other in dynamic ways to shape health. It’s a complex, ever-changing dance, where the aim isn’t a static “balance” but a dynamic equilibrium, capable of adapting and adjusting to ever-changing internal and external demands. This highlights the importance of a holistic, interdisciplinary approach to health and well-being that recognizes and values this complexity.
Best Evidence
When building a compelling argument, it’s vital to focus on those areas where there’s a substantial body of empirical evidence. For the argument that all these factors interact in a complex system to influence health and stress responses, here are some areas with a lot of supporting evidence:
- The Interaction of Genetics and Environment (Epigenetics): Numerous studies have shown how the environment can influence gene expression in a process called epigenetics. One famous example is the Dutch Hunger Winter studies, showing that prenatal exposure to famine had long-term health effects on the offspring, mediated by changes in DNA methylation (Heijmans et al., 2008).
- Stress and the Immune System: There is ample evidence showing the bidirectional relationship between stress and the immune system. Chronic stress can lead to inflammatory responses, and these inflammatory markers have been linked with depression, anxiety, and other health issues (Miller et al., 2007).
- The Microbiome and Mental Health: There’s a growing body of research showing the impact of gut health on mental health (the gut-brain axis), with changes in gut microbiota composition associated with stress-related disorders such as depression and anxiety (Foster et al., 2017).
- Nutrition and Mental Health: Nutritional psychiatry has emerged as a field that studies the impact of diet on mental health. For example, research suggests that Mediterranean-style diets rich in fruits, vegetables, legumes, whole grains, fish, and lean meats can help manage depressive symptoms (Parletta et al., 2017).
- Social Determinants of Health: Research consistently shows that social factors like socioeconomic status, education, social support, and access to health care have a major impact on health outcomes, including stress-related conditions (Braveman et al., 2011).
- Adverse Childhood Experiences (ACEs) and Long-term Health: Studies have shown that ACEs like abuse, neglect, and household dysfunction can have long-lasting effects on mental and physical health, in part through maladaptive stress responses (Felitti et al., 1998).
- Intersectional Trauma and Health: There’s a growing recognition of how intersectional identities (e.g., race, gender, socioeconomic status, disability) influence experiences of stress and trauma, and how these experiences in turn impact health (Crenshaw, 1991; Lewis et al., 2015).
