Cortisol Awakening Response, Percent Increase

Saliva

Other names: CAR

check icon Optimal Result: 50 - 150 %.

The "Cortisol Awakening Response, Percent Increase" (CAR) is a crucial marker measured in the 4300 Adrenocortex Stress Profile - Saliva test by Genova Diagnostics. This test assesses how your cortisol levels change shortly after you wake up in the morning. Cortisol is a hormone produced by the adrenal glands that plays a vital role in managing stress, maintaining energy levels, and regulating various body functions. Normally, cortisol levels rise sharply within the first 30 to 45 minutes after waking up, a phenomenon known as the cortisol awakening response. The CAR, expressed as a percent increase, helps to gauge the responsiveness of your adrenal glands and their ability to produce cortisol in response to the anticipation of the day's demands. An appropriate CAR indicates that your body is effectively preparing itself to handle the upcoming physical and psychological activities. However, deviations from the normal percent increase, either too low or too high, can indicate potential issues with adrenal function or chronic stress. For example, a blunted CAR might suggest adrenal fatigue, chronic stress, or burnout, while an exaggerated CAR could be associated with heightened stress sensitivity or anxiety. Understanding your CAR can provide valuable insights into your overall stress response and adrenal health, helping healthcare providers tailor strategies to manage stress and improve well-being.

What does it mean if your Cortisol Awakening Response, Percent Increase result is too high?

Elevated levels of the Cortisol Awakening Response (CAR) indicate that the body is producing an excessive amount of cortisol shortly after waking up. This heightened response can be a sign of chronic stress, anxiety, or an overactive adrenal response. It suggests that the body is in a heightened state of alertness, possibly preparing for a stressful day, even when such stress might not be present. Persistent high levels of cortisol can lead to various health issues, including increased blood pressure, weight gain, impaired cognitive function, and a weakened immune system.

To manage and treat elevated CAR levels, several strategies can be employed. Stress management techniques such as mindfulness meditation, yoga, and deep-breathing exercises can help reduce overall stress levels and normalize cortisol production. Regular physical activity is also beneficial, as it helps regulate the body’s stress response and promotes overall well-being. Ensuring adequate sleep and maintaining a consistent sleep schedule are crucial, as poor sleep can exacerbate cortisol dysregulation. Dietary adjustments, such as reducing caffeine and sugar intake and eating a balanced diet rich in whole foods, can also support adrenal health.

In some cases, professional counseling or therapy might be necessary to address underlying stress or anxiety issues. Cognitive-behavioral therapy (CBT) is particularly effective in helping individuals develop healthier responses to stress. Additionally, in consultation with a healthcare provider, certain supplements or medications might be recommended to support adrenal function and manage cortisol levels. These might include adaptogenic herbs like ashwagandha or rhodiola, which help the body adapt to stress. Regular monitoring of cortisol levels and follow-up with a healthcare provider can ensure that treatment strategies are effective and adjusted as needed.

What does it mean if your Cortisol Awakening Response, Percent Increase result is too low?

Decreased levels of the cortisol awakening response (CAR) indicate that the adrenal glands are not producing enough cortisol upon waking, which can suggest several underlying issues. These may include chronic stress, adrenal fatigue, burnout, or conditions like depression and chronic fatigue syndrome. When the body is under prolonged stress, the adrenal glands can become overworked and unable to produce adequate cortisol, leading to a blunted CAR. This insufficient response can result in symptoms such as fatigue, low energy, difficulty waking up in the morning, poor stress tolerance, and overall reduced resilience to daily challenges.

Treating decreased CAR involves a multifaceted approach aimed at reducing stress and supporting adrenal health. Stress management techniques are crucial, including practices like mindfulness meditation, yoga, and deep-breathing exercises, which can help lower overall stress levels and improve adrenal function. Adequate sleep and maintaining a regular sleep-wake cycle are also important, as they support the natural rhythm of cortisol production. Additionally, a balanced diet rich in nutrients that support adrenal health, such as vitamin C, B vitamins, and magnesium, can be beneficial. Regular physical activity, tailored to the individual’s energy levels, can help regulate cortisol levels and improve overall well-being. In some cases, adaptogenic herbs like ashwagandha or rhodiola may be recommended to help balance stress hormones and support adrenal function. Consulting with a healthcare provider to tailor a treatment plan that addresses the specific needs and underlying causes is essential for effectively managing decreased CAR and improving overall health.

What Healthmatters Members Are Saying

5 stars rating

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with  any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
