Cortisol: What Causes High Cortisol Levels?
Cortisol is often called the body’s “stress hormone,” but its role goes far beyond stressful moments. When balanced, it helps regulate energy, mood, immunity, and daily rhythm. But when cortisol rises too high for too long, it can leave you feeling wired, tired, and out of sync. Understanding what causes high cortisol levels is the first step toward restoring balance—naturally and sustainably.
What Is Cortisol?
Cortisol is a steroid hormone produced by the adrenal glands. It’s part of the body’s stress response system, known as the HPA (hypothalamic-pituitary-adrenal) axis. In short bursts, cortisol is helpful. It wakes you up in the morning, supports metabolism, and helps the body respond to challenges.
However, when cortisol stays elevated over time, it can affect mood, energy, sleep, digestion, and overall wellbeing.
What Causes High Cortisol Levels?
Several lifestyle, emotional, and environmental factors can push cortisol beyond healthy ranges. Here are the most common causes.
1. Chronic Stress
Long-term stress—whether psychological, emotional, or physical—is one of the leading contributors to prolonged high cortisol. The body doesn’t distinguish between work stress, financial worries, intense exercise, or emotional strain. Any ongoing stressor can keep the HPA axis switched “on.”
2. Poor Sleep
Sleep deprivation and irregular sleep patterns disrupt circadian rhythms, which regulate cortisol levels throughout the day. When sleep suffers, morning cortisol spikes may become exaggerated, or cortisol may remain high at night when it should naturally drop.
3. Excessive Caffeine or Stimulants
High caffeine intake can increase cortisol production by stimulating the adrenal glands. If you rely on multiple coffees or energy drinks daily, cortisol may stay elevated for hours.
4. Intense or Prolonged Exercise
Movement is essential for wellbeing—but very intense exercise performed too frequently can increase cortisol. This is especially true if recovery, nutrition, or sleep are lacking.
5. Blood Sugar Imbalances
Fluctuating blood sugar can trigger cortisol spikes, especially when meals are skipped or when diets are high in refined carbohydrates and low in protein or fibre. Cortisol helps mobilise glucose, so the hormone rises to compensate.
6. Emotional Burnout
Ayurveda teaches that emotional wellbeing is intimately tied to physical balance. Unprocessed emotion, ongoing worry, or mental fatigue can gradually elevate cortisol over time.
Common Symptoms of High Cortisol
While symptoms vary from person to person, many people with high cortisol notice changes in energy, mood, and physical wellbeing.
- Feeling tired but wired
- Difficulty winding down at night
- Morning grogginess
- Mood fluctuations
- Increased cravings or appetite changes
- Digestive upset
- Reduced resilience to stress
- Brain fog or difficulty concentrating
How Lifestyle Affects Cortisol Levels
The good news: lifestyle shifts can have a meaningful influence on cortisol patterns. Modern research increasingly supports the ancient Ayurvedic belief that balance comes from daily rhythms and mindful habits.
Grounding Foods
Meals rich in whole foods, healthy fats, fibre, and stable sources of protein help keep blood sugar and energy stable—reducing unnecessary cortisol spikes.
- Warm, cooked meals
- Root vegetables
- Healthy fats like ghee or olive oil
- Herbal teas
Rhythmic Sleep Patterns
Going to bed and waking up at consistent times signals the body to regulate cortisol more effectively. Ayurveda also encourages winding down before 10 pm when the body naturally shifts into restoration mode.
Gentle Movement
Walking, yoga, breathing practices, or resistance training (with proper rest) can reduce stress-induced cortisol elevation and support a balanced stress response.
Nervous System Regulation
Calming practices help guide the body out of “fight or flight.”
- Deep breathing
- Meditation
- Journaling
- Mindful breaks throughout the day
Where Supplements Fit Into Cortisol Balance
While lifestyle foundations create long-term stability, targeted supplements can offer additional support for those experiencing high cortisol levels. Many people turn to adaptogens—herbs traditionally used in Ayurveda to support the body's ability to adapt to physical and emotional stressors.
Adaptogens are known for helping the body return to balance rather than pushing it in one direction. Modern research continues to explore how these botanicals may influence cortisol rhythms and overall stress resilience.

Frequently Asked Questions
What causes cortisol to rise suddenly?
Sudden spikes often occur from acute stress, caffeine, intense exercise, or abrupt blood sugar changes. These short-term rises are normal, but repeated spikes can contribute to chronic elevation.
Can high cortisol affect sleep?
Yes. If cortisol remains elevated at night, it may make it harder to unwind, fall asleep, or stay asleep.
What is the fastest way to calm cortisol naturally?
Slow breathing, gentle movement, hydration, and stepping away from stress triggers can help bring the nervous system into a calmer state.
Does diet influence cortisol levels?
Very much so. Balanced meals that support stable blood sugar can help keep cortisol fluctuations in check.
How long does it take to lower high cortisol?
It varies by individual and depends on stress levels, sleep quality, lifestyle habits, and consistency with supportive practices.
Are adaptogens helpful for high cortisol?
Adaptogens are traditionally used to support the body’s response to stress. Many people incorporate them to help promote a balanced sense of calm.
Can exercise reduce cortisol?
Moderate exercise can support healthier cortisol patterns, while excessive or high-intensity training without rest may increase it.
Is high cortisol the same as burnout?
Not exactly. High cortisol can contribute to burnout, but burnout also involves emotional, mental, and physical fatigue.
Does cortisol affect digestion?
Yes. When the body is in a stress-dominant state, digestion may become less efficient, which some people experience as bloating or appetite changes.
Can supplements help balance cortisol?
Supplements, especially adaptogen-based formulas, may support the body's natural stress response and complement lifestyle changes.
