What can I learn from a cortisol test?

Your cortisol levels naturally fluctuate throughout the day — they should be highest in the morning around 8am and gradually drop so they reach their lowest point at night. We recommend you use any of Lab Me’s at-home test’s containing cortisol at 8am.

Our at home blood test can help you learn if things like sleep problems, low energy levels, low mood, getting sick often, and weight gain might be because your cortisol levels are too high.

Based on your results, you’ll get personalised advice that you can use with your MD on how to improve your levels.

Cortisol hormone & function explained

Cortisol is your primary stress hormone.

On top of helping you cope with stress, it helps regulate your blood sugar, regulates your blood pressure, & converts food to energy.

What happens if it gets too high?

If your cortisol hormone gets too high, many issues may arise.

A few things that can cause your cortisol to spike are chronic stress or certain medications.

High cortisol levels can cause a wide range of issues, including weight gain, tiredness, acne, thinning hair, low sex drive, anxiety, depression, irregular periods, and getting sick often.

This is why testing your cortisol hormone & function regularly is important, especially if you are experiencing any of the above symptoms.

What happens if Cortisol gets too low?

Weakness, fatigue, and low blood pressure.

You may have more symptoms if you have untreated Addison's disease or damaged adrenal glands due to severe stress, such as from a car accident or an infection. These symptoms include sudden dizziness, vomiting, and even loss of consciousness.

Tracking this overtime allows you to detect patterns in your cortisol levels and help you work with your healthcare provider. The earlier you start to test, the earlier you can avoid issues.

How to lower your Cortisol levels

Ask the scientists have a great article including ways to lower your cortisol levels. This is what they suggest:

  • Prioritize exercise. This can be walking, swimming, gardening, or playing with your kids.
  • Incorporate daily meditation. Take a few moments to tune out your stresses and tune into your body and mind.
  • Focus on deep breathing. Full, deep breaths can reduce cortisol and help you calm down when you feel overwhelmed.
  • Practice yoga. This form of stretching combines meditation and exercise, which adds up to relaxation.
  • Find helpful distractions. Work on your favorite hobbies, serve someone in need, or complete a manageable task around your house. Being productive can turn your thoughts away from what is stressing you out.
  • Get a restful night of sleep. Cortisol levels are cyclical. When you don’t sleep enough, cortisol stays elevated and can leave you feeling even more stressed.
  • Eat a healthy meal. Fill your belly with a good meal made of whole, nutritious foods to fuel your body.
  • Learn to say “no.” This one is hard. Don’t take on more responsibilities than you can handle. Avoid spreading yourself too thin and prioritize the most important tasks.
