Stress is a natural part of life, but when it becomes chronic, it can take a toll on your health. One way to measure how stress affects your body is through a cortisol test. Cortisol, often called the "stress hormone," plays a crucial role in regulating metabolism, blood pressure, and immune function. However, too much or too little cortisol can lead to health problems.
This article will help you understand:

Ways to manage stress and balance cortisol levels
What is Cortisol?
Cortisol is a hormone produced by the adrenal glands, which are small glands located on top of your kidneys. It helps your body:
Respond to stress
Control blood sugar levels
Regulate metabolism
Reduce inflammation
Maintain blood pressure
Cortisol levels naturally fluctuate throughout the day—highest in the morning to help you wake up and lowest at night to promote sleep. However, chronic stress, poor sleep, or medical conditions can disrupt this balance, leading to health issues.
Why Might You Need a Cortisol Test?
A doctor may recommend a cortisol test if you have symptoms of:
High Cortisol (Cushing’s Syndrome)
Unexplained weight gain (especially around the face and abdomen)
High blood pressure
Muscle weakness
Mood swings, anxiety, or depression
Irregular periods (in women)
Thinning skin or easy bruising
Low Cortisol (Addison’s Disease or Adrenal Fatigue)
Extreme fatigue
Low blood pressure
Dizziness or fainting
Darkening of the skin
Salt cravings
Nausea and vomiting
The test can also help diagnose problems with the pituitary gland or adrenal glands, which control cortisol production.

How is the Cortisol Test Done?
There are different ways to measure cortisol levels:
1. Blood Test – A simple blood draw, usually done in the morning when cortisol is highest.
2. Saliva Test – You collect saliva samples at different times (often at night) to check cortisol rhythm.
3. Urine Test – A 24-hour urine collection measures total cortisol output.
Your doctor will decide which test is best based on your symptoms.
What Do Abnormal Results Mean?
High Cortisol Levels
Chronic stress (from work, relationships, or illness)
Cushing’s syndrome (due to tumors or steroid medications)
Pituitary gland disorders
Low Cortisol Levels
Addison’s disease (adrenal gland damage)
Adrenal fatigue (from prolonged stress)
Pituitary gland problems
If your results are abnormal, your doctor may suggest further tests (like an ACTH stimulation test or imaging scans) to find the cause.
How Can You Manage Cortisol Levels Naturally?
If stress is affecting your cortisol levels, these lifestyle changes can help:
1. Reduce Stress
Practice deep breathing, meditation, or yoga
Spend time in nature
Engage in hobbies you enjoy
2. Improve Sleep
Maintain a regular sleep schedule
Avoid screens before bedtime
Keep your bedroom dark and cool
3. Eat a Balanced Diet
Include protein, healthy fats, and fiber to stabilize blood sugar
Reduce caffeine and sugar, which can spike cortisol
Eat magnesium-rich foods (leafy greens, nuts, seeds)
4. Exercise Moderately
Walking, swimming, or gentle yoga can lower stress
Avoid overtraining, which can increase cortisol
5. Stay Hydrated
Dehydration can increase stress on the body
6. Consider Supplements (After Consulting a Doctor)
Ashwagandha, omega-3s, and vitamin C may help regulate cortisol
