Q: What does the normal cortisol curve look like during the day?

A: Cortisol in the morning should be high. It reaches a peak when we rise in the morning and during the day it should come down so that by the time you go to sleep at night time it is usually at its low. That is the normal cortisol curve. Bear in mind this cortisol curve can change drastically from person to person. Even though the average cortisol tends to be relatively stable throughout our lifetime, many factors including whether you are on steroids, stress, or have a high sugar diet can affect that level.
