What Causes High Cortisol Levels? Understanding the Modern Stress Hormone

Cortisol is often called the “stress hormone,” but it’s far more complex than that. When balanced, it helps regulate energy, metabolism, and your natural stress response. But when cortisol levels stay high for too long, everything from mood to sleep to digestion can feel out of sync. If you’re wondering what causes high cortisol levels—and how to restore balance—this guide brings together modern science and Ayurvedic wisdom to help you understand what’s happening inside your body.

What Is Cortisol?

Cortisol is a hormone produced by the adrenal glands. It plays an essential role in keeping you alert, regulating blood sugar, supporting immune function, and responding to stress. Your cortisol levels naturally rise and fall throughout the day, typically peaking in the morning and dipping at night.

Problems start when cortisol remains elevated for long periods, which can happen for many reasons. Understanding these triggers is the first step toward restoring balance.

What Causes High Cortisol Levels?

High cortisol doesn’t come from one single source; it’s usually a combination of lifestyle factors, emotional stressors, and physiological imbalances. Here are the most common contributors.

1. Long-Term Stress

Your body is designed to handle short bursts of stress, not constant pressure. Ongoing work stress, emotional strain, financial worries, or caregiving responsibilities can keep your stress response switched on.

• Chronic workplace stress
• Difficult relationships
• Burnout or exhaustion
• Unresolved emotional tension

2. Poor Sleep

Sleep is one of the biggest regulators of cortisol. Even a few nights of disrupted rest can elevate levels.

• Irregular sleep schedules
• Stimulant use late in the day
• Blue-light exposure before bed
• Waking frequently during the night

3. Blood Sugar Imbalances

When your blood sugar spikes and crashes, cortisol often rises to stabilise your energy. This is common when meals are skipped or heavily processed foods dominate your diet.

4. Over-Exercising

Movement is essential for wellbeing, but pushing too intensely without enough recovery time can raise cortisol rather than reduce it.

5. Caffeine and Stimulants

High caffeine consumption—especially on an empty stomach—can signal the body to release more cortisol.

6. Underlying Health Factors

Hormonal fluctuations, inflammation, and metabolic changes can all play a role. If cortisol stays elevated despite lifestyle adjustments, it may be worth speaking with a health professional.

Common Symptoms of High Cortisol

You may not always realise cortisol is the culprit, but persistent imbalance often shows up in the body and mind. Common signs include:

• Feeling wired but tired
• Difficulty falling or staying asleep
• Midsection weight gain
• Low mood or irritability
• Low energy throughout the day
• Digestive discomfort
• Cravings for sugar or caffeine
• Brain fog

If several of these feel familiar, exploring our cortisol guide can help you understand these patterns more deeply.

Why Cortisol Imbalance Happens: The Modern Perspective

From a scientific standpoint, high cortisol typically means your stress response is being activated too frequently. The brain sends signals to the adrenal glands, which release cortisol to help you respond to perceived danger. But modern life constantly triggers this system—even when there’s no actual threat.

Common modern-day triggers include:

• Digital overload and constant notifications
• Lack of downtime
• Erratic work schedules
• Environmental stressors like noise or pollution

The Ayurvedic Perspective on High Cortisol

In Ayurveda, high cortisol mirrors an imbalance of the Vata and Pitta doshas. Excess Vata creates restlessness, worry, and poor sleep. Excess Pitta shows up as irritability, overworking, and pushing too hard.

Ayurveda encourages balancing these energies through grounding routines, nourishment, and calming herbs.

Lifestyle Changes That May Help Reduce High Cortisol

Restoring balance often requires small, consistent lifestyle shifts. Here are practices shown to support more regulated cortisol rhythms.

1. Prioritise High-Quality Sleep

• Keep a consistent sleep schedule
• Reduce screen time before bed
• Create a dark, cool, comfortable sleep environment
• Use calming evening rituals like herbal tea or gentle stretching

2. Choose Balanced Nutrition

• Eat regular meals with protein, fibre, and healthy fats
• Limit refined sugar and highly processed snacks
• Add magnesium-rich foods like dark leafy greens
• Stay well-hydrated

3. Support Healthy Movement

• Incorporate moderate exercise like walking or yoga
• Balance intense workouts with adequate recovery
• Try grounding outdoor activities

4. Build Mind–Body Reset Moments

• Breathwork practices such as slow belly breathing
• Short mindfulness sessions throughout the day
• Limiting caffeine, especially in the afternoon

Where Supplements Fit Into Cortisol Balance

While lifestyle changes create the foundation, certain nutrients and botanicals can support the body’s natural stress response. Adaptogenic herbs—used for centuries in Ayurveda—are known for helping the body adapt to physical and emotional stress.

Common adaptogens used for cortisol support include:

• Ashwagandha
• Rhodiola
• Holy basil (tulsi)
• L-theanine
• Magnesium

These ingredients don’t override your stress response—they simply support how your body manages it.
