Cortisol is a steroid hormone produced by the adrenal glands and plays a crucial role in the body’s stress response, metabolism, immune function, and regulation of the circadian rhythm. Salivary cortisol measurement has become a widely used non-invasive method for assessing cortisol levels due to the ease of sample collection and its ability to reflect free, biologically active cortisol in the bloodstream. Unlike blood or urine, saliva samples do not require specialized equipment or invasive procedures, making it ideal for repeated measures, particularly in field studies or clinical settings.
In research and clinical settings, salivary cortisol is used to study the body’s response to stress, sleep disorders, adrenal function, and various endocrine disorders. It is especially valuable in examining circadian rhythms, as cortisol levels naturally fluctuate throughout the day. The timing of saliva collection (e.g., morning peak, evening drop) is critical for understanding cortisol’s diurnal pattern and assessing potential disruptions in conditions like chronic stress, depression, and anxiety. Additionally, saliva cortisol testing is frequently used in studies investigating the physiological impact of trauma, mental health disorders, and the body’s stress adaptation, providing a non-invasive and reliable tool for ongoing monitoring of endocrine health.
