The daily cortisol rhythm
Your body runs on a 24-hour clock.
Cortisol is more than a stress signal. It rises and falls on a schedule, and late light, caffeine and short nights all tug at that schedule.
Shape traced from 24-hour cortisol profiles of 33 healthy adults [8]. Relative scale, not lab values. Your own timing moves with when you sleep and wake.
| When | What the research shows |
|---|---|
| Around midnight | Cortisol reaches its lowest point of the 24 hours. [8] |
| 2 to 3 AM | Levels start to rise and build overnight toward a morning peak around 8:30 AM. [8] |
| First 30 to 45 min awake | A marked rise after waking, known as the cortisol awakening response. [9][10] |
| Daytime coffee | Caffeine raised cortisol in a controlled trial. In daily drinkers the response was reduced, not eliminated. [14] |
| The evening after a short night | Evening cortisol ran higher after partial or total sleep loss, in a small study of young men. [12] |
| Reading on screens at night | A light-emitting e-reader before bed delayed the body clock and reduced melatonin, compared with a printed book. [16] |

Cortisol and sleep, answered
What is cortisol?
A steroid hormone made by the adrenal glands. It runs on a daily rhythm: in 24-hour profiles of 33 healthy adults it was lowest around midnight, started rising around 2 to 3 AM, peaked around 8:30 AM, then slowly fell back. [8]
What is the cortisol awakening response?
The marked rise in cortisol over roughly the first 30 to 45 minutes after you wake. Measuring it properly needs saliva samples timed precisely from the moment of waking. [9][10]
What is a circadian rhythm?
Your body’s roughly 24-hour cycle. A master clock in the brain stays in step with the day through light signals from the eyes, which is why light late at night can shift sleep and other rhythms. [17] More terms in the glossary
How are cortisol levels checked?
Clinicians use blood, saliva or urine tests, often timed to the daily rhythm. Because no single test is perfect, they usually use more than one. Home saliva kits exist, but the results need a clinician to interpret. [24][10]
What is a normal cortisol level?
There is no single number. Reference ranges depend on the type of test, the lab and the time the sample was taken, because levels swing across the 24 hours. Your lab report lists its own range, and a clinician can explain what yours means. [8][24]
Is "cortisol belly" a real condition?
It is a social media phrase, not a diagnosis. Weight around the middle has many possible causes. Truly high cortisol from a condition such as Cushing’s syndrome is diagnosed with clinical testing. [24][25]
What is sleep debt?
An informal name for the gap between the sleep you aim for and the sleep you actually get, added up over several nights. It is a useful pattern to watch, not a medical measurement. Try the sleep debt calculator
Do screens before bed affect sleep?
In one lab study, reading on a light-emitting e-reader before bed meant taking longer to fall asleep, less melatonin, a later body clock and lower alertness the next morning than reading a printed book. [16] Plan your sleep window
