What Is Cortisol?

Cortisol is a steroid hormone produced by the adrenal glands. Located just above the kidneys, these glands release cortisol into the bloodstream.

Cortisol, often called the “stress hormone” it helps our body respond to stress and also regulates metabolism by converting proteins, fats, and carbohydrates into usable energy. Additionally, cortisol modulates inflammation and immune responses, keeping our system in balance.

This hormone follows a natural daily rhythm, peaking in the morning to kick-start your day and gradually declining as the day goes on. Understanding this cycle is key to recognizing how cortisol supports both energy and overall health.

Typical Cortisol Levels:

Morning (8 a.m. – 9 a.m.) – 10-20 Cortisol Level (micrograms per deciliter)
Evening (4 p.m. – 5 p.m.) – 3-10 Cortisol Level (micrograms per deciliter)

What is stress?

Stress is a response to external pressures and internal conflicts. Though it can be beneficial in small amounts, chronic stress impacts both physical and mental well-being.

Common sources of stress

Everyday stressors range from work deadlines, financial worries, to personal relationships. Unpredictable events such as health issues or natural disasters also contribute.

Social stress, like navigating intense social situations, adds another layer. Chronic pressures can result from ongoing life situations such as caregiving or living in poverty.

Why stress is on the rise

Modern life intensifies stress through constant connectivity and high demands. Technology plays a major role, with devices keeping individuals tethered to work and social media fostering unrealistic comparisons. Economic uncertainties and political climates add to the pervasive anxiety today.

How does stress affect the body?

Stress activates the body’s fight or flight response, releasing adrenaline and cortisol. Physical symptoms include increased heart rate, muscle tension, and perspiration. Chronic stress may lead to long-term health problems such as hypertension, diabetes, and weakened immune function. Mental impacts like anxiety and depression are also common.

Which hormones are associated with stress?

Several hormones are involved in the stress response. Cortisol, known as the primary stress hormone, regulates energy and enhances the body’s ability to handle stress. Adrenaline increases heart rate and energy levels. Other hormones like norepinephrine also play roles in the stress response.

Acute stress vs. chronic stress

Acute stress is short-term, often resulting from a specific event like an exam or traffic jam. It can be beneficial, providing a burst of energy or focus. Chronic stress is prolonged and persistent, often stemming from ongoing concerns such as job pressures or long-term illness. Chronic stress is more harmful and requires proactive management.

Effects of Excess Cortisol Levels

High cortisol levels can impact various aspects of health, both physically and psychologically. The key areas affected include physical symptoms and psychological symptoms, along with noticeable signs.

Elevated Cortisol Levels

Increased cortisol can lead to noticeable changes. Weight gain, especially around the abdomen, is a common sign. Individuals may also observe rounding of the face and fat deposits between the shoulders, known as buffalo hump.

Another symptom can include skin changes, such as thinning and easy bruising. Many people experience a rise in blood pressure and muscle weakness. Frequent infections may also be a sign, as high cortisol can suppress the immune system.

Physical Symptoms

High cortisol levels contribute to specific physical health issues. Hypertension or high blood pressure is prevalent. Elevated glucose levels can lead to Type 2 diabetes.

Muscle wasting and fatigue are common, impacting daily functions. Bone density reduction may occur, increasing the risk of osteoporosis.

Women might experience irregular menstrual cycles and men could face decreased libido and erectile dysfunction. Persistent high cortisol can also affect gastrointestinal health, causing ulcers and irritable bowel syndrome (IBS).

Psychological Symptoms

Psychologically, high cortisol levels can lead to various mental health issues. Depression is frequently reported, often accompanied by heightened anxiety.

7. Have Fun and Laugh

Engaging in activities that make you laugh or bring happiness can decrease cortisol levels. Watching funny movies, reading humorous books, or spending time with friends who make you laugh can be effective. Laughter triggers the release of endorphins, the body’s natural feel-good chemicals, which can combat cortisol.

8. Maintain Healthy Relationships

Positive relationships can buffer against stress and lower cortisol. Spending time with loved ones, communicating openly, and resolving conflicts healthily are important. Social support from friends and family can provide emotional comfort, significantly impacting cortisol regulation.

9. Tend to Your Spirituality

Spiritual practices like prayer, meditation, or attending religious services can provide a sense of peace and reduce stress. These practices can offer perspective, comfort, and community support. Engaging in regular spiritual activities can create a routine that fosters relaxation and lowers cortisol.

10. Take Certain Supplements

Supplements like ashwagandha, Rhodiola, and fish oil have been studied for their cortisol-lowering effects. Ashwagandha is an adaptogen that helps the body manage stress. Rhodiola can reduce fatigue and improve stress resilience. Fish oil supplements may help reduce inflammation and improve mood. Consulting with a healthcare provider before starting any supplement is recommended.
