What Causes High Cortisol Levels? Understanding Stress, Triggers, and Natural Balance

Cortisol has become one of the most talked‑about hormones in modern wellness, and for good reason. When balanced, it helps you wake up, stay focused, and respond to life’s demands. But when levels rise too high for too long, everything from your energy to your mood can shift. If you’ve ever wondered what causes high cortisol levels, you’re not alone. This guide breaks down the science, the signs, and the everyday habits that influence this vital hormone—plus where holistic tools can support balance.

What Is Cortisol?

Cortisol is a steroid hormone produced by the adrenal glands, released in response to signals from the brain. Often called the “stress hormone,” it’s part of your body’s natural survival system. It rises when you need energy fast and drops when you’re safe and ready to rest. Cortisol follows a daily rhythm, peaking in the morning and gradually lowering throughout the day.

What Causes High Cortisol Levels?

High cortisol, sometimes called hypercortisolism, happens when the body stays in a prolonged state of alertness. While acute spikes are normal, chronic elevation can affect sleep, appetite, hormones, and overall wellbeing. Here are the most common causes.

1. Chronic Stress

This is the most frequent and impactful trigger. When your body perceives ongoing pressure—whether emotional, mental, or environmental—it keeps cortisol elevated. Sources include:

• Work pressure or burnout
• Relationship or family stress
• Financial worries
• Information overload
• Constant multitasking

Because the modern world offers little downtime, many people live in a near‑constant stress response without realising it.

2. Poor Sleep Quality

Cortisol and sleep are deeply intertwined. Lack of deep, restorative rest can disrupt the hypothalamic‑pituitary‑adrenal (HPA) axis, causing cortisol to rise at night when it should be at its lowest.

3. Overtraining or Intense Exercise Without Recovery

While movement is healthy, pushing the body too hard without adequate rest increases cortisol. This is especially common in high‑intensity training, endurance sports, or back‑to‑back workouts.

4. Blood Sugar Imbalances

Skipping meals, consuming too much sugar, or riding a cycle of highs and lows can signal the body to release cortisol as an emergency energy source.

5. Caffeine and Stimulant Overuse

Caffeine naturally increases cortisol, and in high amounts or on an empty stomach, this effect becomes more pronounced.

6. Underlying Hormonal or Health Conditions

Certain conditions—such as thyroid imbalances, adrenal issues, or long‑term medication use—can influence cortisol, but these are less common. What most people experience is lifestyle‑driven cortisol elevation.

Common Symptoms of High Cortisol

You may not immediately recognise high cortisol, but the body sends signals. These can include:

• Feeling wired but tired
• Difficulty falling or staying asleep
• Midsection weight changes
• Increased cravings, especially for sugar or carbs
• Low mood or irritability
• Frequent energy crashes
• Brain fog or trouble concentrating
• Reduced exercise recovery

If these feel familiar, understanding the root cause is the first step toward improvement. You can explore more in our cortisol guide.

Why High Cortisol Happens: A Deeper Look

High cortisol is rarely caused by a single factor. Instead, it comes from cumulative strain on the body and mind. In Ayurveda, this resembles an excess of Vata—an energy linked to movement, stimulation, and the nervous system. When Vata becomes imbalanced, the body becomes more reactive, restless, and depleted. Modern science mirrors this through the HPA axis, stress responses, and nervous‑system overload.

In both philosophies, the solution lies in gentleness, nourishment, consistency, and habits that help the body feel grounded again.

Lifestyle Shifts That Help Reduce High Cortisol

You can’t eliminate stress entirely, but small shifts can create real change. These habits support a calmer internal environment and healthier cortisol rhythm.

Prioritise Restorative Sleep

• Keep a consistent sleep schedule
• Create a wind‑down ritual each night
• Limit screens one to two hours before bed
• Focus on magnesium‑rich foods or soothing herbal teas

Adopt Nervous-System Calming Practices

• Breathwork (especially slow, deep breaths)
• Gentle yoga or stretching
• Relaxing walks in nature
• Mindfulness or meditation

Support Balanced Energy Through Nutrition

• Eat regular meals to avoid blood sugar dips
• Include protein, fibre, and healthy fats in each meal
• Reduce processed sugar where possible
• Choose warm, grounding meals (Ayurveda‑inspired)

Manage Caffeine Intake

Instead of quitting cold turkey, try reducing caffeine gradually, pairing it with food, or replacing a second cup with herbal options.

Build in Micro‑Recovery Moments

Even 1–2 minutes of pausing between tasks can help reset the body’s stress response. High-performing individuals often overlook this simple but powerful practice.

Where Supplements Fit In

While lifestyle is foundational, certain herbs and nutrients can support your natural stress response. Adaptogens—plants traditionally used in Ayurveda—help the body respond more smoothly to physical and emotional stressors.

Common adaptogens include:

• Ashwagandha
• Holy basil
• Rhodiola
• Panax ginseng

These herbs don’t switch cortisol off; they support a more stable, resilient response over time.

Does lack of sleep increase cortisol?

Poor sleep disrupts your natural cortisol rhythm and can keep levels elevated at night.

Can high cortisol cause weight changes?

It can contribute to shifts in appetite and energy usage, which may influence weight over time.

Is exercise good or bad for cortisol?

Moderate exercise supports healthy cortisol patterns, but overtraining without recovery may increase it.

How long does it take to balance cortisol?

Everyone is different, but consistent lifestyle habits can support change over weeks to months.

Are adaptogens safe for daily use?

Many people use adaptogens daily, but it’s helpful to start slowly and pay attention to how your body responds.

Can diet alone lower cortisol?

Diet helps, but a combination of sleep, stress‑management habits, movement, and supportive tools often works best.
