Understanding Cortisol

Definition of Cortisol

Cortisol is a steroid hormone produced by the adrenal glands situated just above the kidneys. It is released in response to stress and low blood-glucose concentration. Often described as the stress hormone, cortisol also helps in the regulation of a range of functions right from metabolism and immune response to stress response.

How Cortisol is Produced

Cortisol is first produced in the brain. The hypothalamus signals the pituitary gland, which in turn signals the adrenal glands to release cortisol. This is an HPA axis process—for hypothalamic-pituitary-adrenal. Cortisol is released into the blood systematically when you are under any form of stressful circumstance through the HPA axis to allow you to deal with the stressor.

Normal Cortisol Levels

What Are Normal Cortisol Levels?

Normal cortisol levels can vary during different parts of the day. Normally, they are greatest in the morning right as the body awakens, then will naturally decrease during the day. Normal levels of cortisol can range from 10 to 20 micrograms per deciliter (mcg/dL) in the morning and will drop to 3 to 10 mcg/dL in the evening. These are going to vary depending on several different factors such as age, stress, and sometimes even physical activities.

Testing Cortisol Levels

Cortisol can be assessed by testing blood, saliva, or urine samples. For blood testing, the samples are usually taken in the morning when cortisol secretions are highest. Saliva samples may be taken at random times during the day because cortisol levels fluctuate continuously. Urine samples reveal the amount of cortisol excreted over 24 hours. Preparation for a cortisol test generally consists of avoiding stress, certain medications, and heavy physical activity in advance of the test.

Symptoms of High Cortisol Levels

Physical Symptoms

Excess cortisol in the body is reflected in a plethora of physical symptoms. It leads to weight gain, especially in the central or mid-belly region, high blood pressure, and muscle weakness. Other physical symptoms include changes in skin condition, such as thin, fragile skin, easy bruising of the skin, and cuts slow to heal.

Mental and Emotional Symptoms

High cortisol over time can also take a toll on your mental well-being. Signs of high cortisol in human individuals are mainly anxiety, depression, irritability, and mood swings. In addition, issues may arise while being able to concentrate and recall memories—an effect of extremely high cortisol over a long duration.

Long-Term Effects of High Cortisol

Chronically high cortisol can result in prolonged blood sugar abnormalities, leading to type 2 diabetes, hypertension or heart attack, and bone loss or osteoporosis. When you have high levels over a more extended period, you will suppress the immune system, which will make you susceptible to infections and other diseases.

Causes of High Cortisol Level

Stress and Anxiety

One of the prime reasons for excessive levels of cortisol in the body is stress. When you take stress, either physical or emotional, your body extrudes cortisol to fight against it. However constant stress can lead to the cortisol going high again and remaining high consistently, which is very unhealthy.

Medical Conditions

High levels of cortisol can also be one effect of medical conditions. For example, Cushing’s syndrome is a medical condition where the body makes an excessive amount of cortisol over an extended period. Other medical conditions that can cause high levels of cortisol include tumors of the adrenal glands.

Lifestyle Factors

Lifestyle choices are mainly what determines cortisol in the body. Fast foods, a sedentary life without much exercise to talk about, and lack of sleep are the main causes of high levels of cortisol. Besides, too much coffee and alcohol increase the level of cortisol.

Lifestyle changes can help greatly in reducing high cortisol levels. A balanced diet with more whole foods, an ample amount of exercise, and good sleep are essential in keeping cortisol level in check. A reduction in caffeine intake and alcohol is also highly recommended.

Stress Management Techniques

Stress management is very important for controlling cortisol levels. Strategies include mindfulness, meditation, and yoga to reduce stress and thereby lower cortisol production. Important tools for stress management are deep breathing exercises and progressive muscle relaxation.

Medical and Alternative Treatments

In some cases, one may require medical attention to keep levels of cortisol in check. Some drugs can be administered to regularize cortisol production in your body. Alternative therapies such as acupuncture, besides herbal supplements including ashwagandha and Rhodiola, also contribute to keeping a level of cortisol in balance. Always consult a professional in health before starting treatment.
