[Objectivity regarding stress: looking the past, evaluating the present...a chance in the future]

Area of Science:

• Psychoneuroimmunology
• Stress Physiology
• Biomarker Research

Context:

• Stress significantly impacts human health, influencing neuroendocrine and immune systems.
• Accurate stress assessment is crucial for understanding and managing associated diseases.
• Previous methods for stress evaluation have limitations in capturing real-time physiological responses.

Purpose:

• To investigate stress through a dual approach: psycho-diagnostic testing and salivary biomarker analysis.
• To evaluate the utility of salivary cortisol and Interleukin-1 Beta (IL1 Beta) as objective stress indicators.
• To explore the relationship between Heart Rate Variability (HRV) and perceived work-related stress.

Summary:

• The study employed psycho-diagnostic tests and measured salivary cortisol and IL1 Beta to assess stress.
• Salivary marker analysis revealed significant variability, suggesting potential correlations with disease states when considering diurnal variations.
• Heart Rate Variability (HRV) parameters indicated that stress effects on the autonomic nervous system are more pronounced during holidays than during work.

Impact:

• Salivary biomarkers offer a practical and potentially more reliable method for stress assessment compared to traditional methods.
• Understanding diurnal variations in salivary markers can aid in early disease detection and personalized stress management strategies.
• The findings highlight the importance of considering the timing and context of stressor exposure when evaluating physiological stress responses.
