Cortisol PM

Cortisol is your body’s main stress manager, helping you wake up, wind down, and react to challenges.

📋 About This Biomarker

Picture cortisol as your body’s built-in alarm system - it’s the hormone that kicks you into gear when you face a challenge and helps you chill out when it’s over. Produced by your adrenal glands, it’s famously known as the “stress hormone” because it gears up during stressful times. But it’s not just about stress; cortisol helps control blood sugar levels, regulate metabolism, and reduce inflammation. It plays a key role in helping you wake up in the morning, powering through the day, and calming down at night.

🎯 Why We Test This

Testing your cortisol levels is like checking the status of your internal stress thermostat. It’s essential for diagnosing conditions like Addison's disease, where cortisol is too low, or Cushing's syndrome, where it's too high. Abnormal levels can impact more than just mood - they can affect sleep, weight, and how your body fights infections. Understanding your cortisol levels can help tailor strategies to manage stress, diet, and medication more effectively.

⚠️ What Affects It

Cortisol levels can be influenced by a variety of factors, including your sleep pattern, physical activity level, stress, diet, and underlying health conditions. Even the time of day can affect your cortisol levels, as they naturally fluctuate throughout the day.

📈 How to Improve

Balancing cortisol is all about managing how you charge up and wind down. High cortisol can often be tackled by incorporating relaxation techniques, such as mindfulness, yoga, or regular exercise, and by ensuring you have a sleep-friendly bedtime routine. Low cortisol might need a diet rich in vitamins and minerals that support adrenal health, and possibly medical interventions like hormone replacement if advised by your doctor.

📊 Understanding Your Results (nmol/L)

Low (< 95 nmol/L)
Low cortisol levels can make you feel like you’ve got no fuel left in the tank - leading to chronic fatigue, low blood pressure, and even depression. This condition, often related to adrenal insufficiency, requires medical attention to manage effectively and ensure your body can respond to stress appropriately.
Optimal (95 - 619 nmol/L)
Cortisol levels in the normal range mean that your body’s stress management system is doing its job right. You’re likely able to handle daily stressors effectively, wake up feeling refreshed, and wind down properly at night. Maintaining this balance is crucial for overall health and well-being. Cortisol levels that are creeping up toward the high end might be an early warning sign that your stress levels are getting out of hand. You might start experiencing difficulty sleeping, moodiness, and a general feeling of being burnt out. It's a good time to look into stress-reducing activities or discuss your concerns with a healthcare provider. When cortisol levels are borderline low, you might start to feel more fatigued than usual, less able to handle stress, and generally sluggish. This can be a hint that your adrenal glands might not be keeping up with your body’s demands, and it might be wise to boost your overall health with proper nutrition, adequate rest, and perhaps medical advice.
High (> 619 nmol/L)
If your cortisol levels are on the high end, it's like your body's stress response is stuck in the "on" position. This can lead to symptoms like weight gain, high blood pressure, and muscle weakness. It can also throw off your sleep patterns and mood, making you feel constantly wired and unable to relax.
