What is Cortisol?

Cortisol is a hormone produced by the adrenal glands located on top of the kidneys. It plays a key role in managing stress, metabolism, and immune response. Cortisol follows a daily cycle, rising in the early morning, peaking about 30 minutes after waking and decreasing in the evening.

Why is Cortisol Important?

Cortisol levels indicate the body’s response to stress. High cortisol can result from acute, chronic, or traumatic stress and is linked to poor sleep, weight gain, and a weakened immune system. Prolonged high levels can lead to conditions like Cushing’s disease. Low cortisol may suggest adrenal issues or Addison’s disease.

Understanding Cortisol Levels

Normal serum cortisol ranges are:

• Morning (6 am – 8 am): 10-15 ug/dL
• Evening (around 4 pm): 4-10 ug/dL

Levels below 3 ug/dL in the morning may indicate adrenal insufficiency, while consistently high levels could signal Cushing’s disease.

3-Point Saliva Test vs. Blood Test

The 3-point saliva test measures cortisol at three different times (morning, afternoon, and night) and is useful for diagnosing disorders affecting cortisol rhythm. The fingerprick blood test is more suitable for general monitoring.

Maintaining Optimal Cortisol Levels

• For High Cortisol:

  • Diet: Include ashwagandha, rhodiola, dark chocolate, and foods high in vitamin C.
  • Lifestyle: Ensure 8 hours of sleep, practice mindfulness, and spend time in nature.

• For Low Cortisol:

  • Lifestyle: Engage in high-intensity exercise and consume caffeine.

If you are concerned about your cortisol levels please consult your physician.
