Cortisol stress diurnal<\/h2>\nEach of us responds to stress in our own unique way. One of the possible reasons for that is how our bodies produce the key \u201cstress hormone,\u201d Cortisol. Measuring its levels over the course of a complete day, a \u201cdiurnal cycle,\u201d is something that can help anyone determine how our bodies are responding and adapting to continued stress.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The Diurnal Cortisol test is one of our foundational hormone tests for measuring levels of adrenal function. It provides a convenient way of measuring Cortisol, the body\u2019s key \u201cstress hormone,\u201d over the course of a day. \n<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Cortisol stress diurnal<\/h3>\nCortisol levels typically follow a curve: They are at their highest in the morning and decline as the day continues. They may fluctuate high or low at any of the four measurement times throughout the day due to acute or chronic stress. Sustained high or low levels are often found in individuals with an imbalance in adrenal function.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
