April is Stress Awareness Month, a great reminder that stress isn’t “just in your head.” Chronic stress can affect sleep, metabolism, immune function, blood pressure, mood, and more—often in ways that look like other health issues.
Why Cortisol Gets All the Attention
Cortisol is a hormone made by your adrenal glands and is essential for your stress response. It also plays roles in blood sugar regulation, inflammation, metabolism, and blood pressure. That’s why it’s commonly called the “stress hormone.”
The important detail: cortisol changes throughout the day
Cortisol normally follows a daily rhythm: it rises after waking and gradually drops toward bedtime. When you’re under chronic stress (or your sleep is disrupted), that rhythm can become irregular.
Cortisol Testing Options (and What Each Can Tell You)
1) Cortisol Test
This is a blood test used to measure the level of cortisol in the blood. Cortisol (also called hydrocortisone) is released by the adrenal gland in response to stress and is part of the body’s “fight or flight” response—helping increase blood sugar, suppress the immune system, and support fat/protein/carbohydrate metabolism for energy.
Helpful for: a straightforward cortisol “snapshot” when you’re exploring symptoms that could relate to cortisol being too high or too low (fatigue, weight changes, blood pressure concerns, etc.)
2) Cortisol Hormone Test (Saliva)
The least invasive way to measure cortisol. Cortisol supports important functions like breaking down fat/protein, stimulating liver glucose production, maintaining blood pressure, helping regulate the immune system/inflammation, and responding to physical and emotional stress.
Helpful for: people who want a non-blood option and want to discuss cortisol results with a provider in the context of stress, energy, immune/inflammation, and overall hormone balance.
3) Cortisol (AM & PM)
This option measures cortisol twice in the same day to better reflect how cortisol changes over time. Cortisol is important for stress response and regulation of blood sugar and blood pressure- timing matters because cortisol levels change throughout the day. You’ll provide two blood samples:
- AM draw: between 7:00AM–9:00AM
- PM draw: between 3:00PM–5:00PM
Helpful for: getting a more complete view than a single value—especially if you’re trying to understand how your body responds upon waking vs. later-day demands and stressors.
4) Sleep Balance Kit
This take-home kit is designed around the connection between hormones and sleep and emphasizes that restoring hormone balance starts with accurate measurement. Collection happens 4 times throughout the day to capture peaks/troughs: waking (nighttime melatonin), ~2 hours later (cortisol awakening response), evening (both should be low), and just before bed (melatonin rising for sleep + cortisol’s lowest point).
Helpful for: people focused on sleep quality who want data on melatonin and cortisol patterns across the day/night cycle.
5) Complete Hormone Health Panel
This panel frames hormones as your body’s “messaging system,” regulating metabolism, blood pressure balance, stress response, sexual function, reproduction, sleep cycle, and mood balance. Hormone shifts can contribute to symptoms like weight changes, fatigue, brain fog, mood disturbances, sleep changes, and changes in sex drive/fertility. This panel targets adrenal, pituitary, and thyroid function to give a complete picture of hormone balance as it relates to mental health, metabolic health, and sexual/reproductive function.
Helpful for: a broader “root cause” approach when stress symptoms overlap with sleep, mood, metabolism, or reproductive hormone concerns.
6) Weight Management Kit
This kit is positioned around the idea that undetected hormone imbalance can be the missing link when reaching/maintaining optimal weight hasn’t worked despite diet and exercise.
Helpful for: connecting stress hormone patterns (diurnal cortisol) plus thyroid and metabolic markers (like insulin and A1c) to weight-management challenges.
When Testing is Especially Worth Considering
Consider testing if you have consistent symptoms such as:
- Persistent fatigue even after sleep
- Anxiety or feeling “wired,” especially at night
- Sleep disruption (trouble falling asleep or waking frequently)
- Weight changes you can’t explain
- Irregular cycles, low libido, or mood swings
- Frequent illness, headaches, or digestive issues
And seek urgent care immediately for chest pain, shortness of breath, fainting, severe depression, or thoughts of self-harm.
