Blood levels of cortisol vary throughout the day, but generally are higher in the morning when we wake up, and then fall throughout the day. This is called a diurnal rhythm. In people that work at night, this pattern is reversed, so the timing of cortisol release is clearly linked to daily activity patterns.
Does Green Tea raise cortisol?

What time of day are cortisol levels highest?

What level of cortisol is considered low?
What the results mean. When a technician carries out the cortisol level test between 6 a.m. and 8 a.m., the results will typically be within the range of 10–20 micrograms per deciliter (mcg/dL) in a healthy person.
