TM reduces cortisol by 30%. Discover how the technique regulates the HPA axis and combats chronic stress.

Meditation and Cortisol Levels

Scientific evidence shows that Transcendental Meditation (TM) is a powerful tool for regulating cortisol levels. It does this by calming the nervous system and reducing unnecessary stress. Read on to find out how it works.

What Is Cortisol?

Cortisol is known as the “stress hormone” because it is released into the bloodstream in greater amounts when you’re stressed. This increases your heart rate and blood pressure. It is an essential part of the “fight-or-flight” response that has kept humans alive for thousands of years. Cortisol performs important functions, such as suppressing inflammation, regulating blood sugar, and supporting metabolism.

However, too much exposure to cortisol can disrupt the body’s processes and lead to health problems such as:

• Anxiety
• Depression
• Cardiovascular disease
• Weakened immune system
• Impaired cognitive function

This is where the TM technique, along with other healthy habits, can make a difference.

Your body constantly monitors cortisol levels to maintain balance, also known as homeostasis. To lower high cortisol levels and keep them at an optimal level, you can, among other things:

• Get a good night’s sleep
• Exercise regularly
• Limit stress and negative thought patterns
• Practice Transcendental Meditation

How does TM lower cortisol?

TM lowers and regulates cortisol levels through various processes:

1. Activation of the parasympathetic nervous system
   TM stimulates the activity of the parasympathetic nervous system, which promotes relaxation and recovery. This shifts the focus away from the “fight-or-flight” response, leading to lower cortisol production.
2. Reduced activity of the amygdala
   The amygdala, the part of the brain associated with stress and anxiety, shows reduced activity during and after TM. This contributes to lower cortisol levels.
3. Improved sleep quality
   Sleep problems, such as insomnia, are often associated with elevated cortisol levels. TM addresses insomnia by tackling stress and anxiety at their core.
4. Improved regulation of the HPA axis
   TM improves the regulation of the hypothalamic-pituitary-adrenal (HPA) axis, which is responsible for cortisol production. Better regulation ensures a more balanced release of cortisol in response to stress.

How Transcendental Meditation Works

Transcendental Meditation is a simple, natural, and effortless technique that is typically practiced for 20 minutes, twice a day, while sitting comfortably with your eyes closed. Unlike other forms of meditation, which require concentration or contemplation, TM uses a mantra—a specific sound or word—to calm the mind and achieve a state of deep relaxation.

After practicing TM, meditators often experience a sense of calm and inner stillness. However, the subtle benefits of TM continue to take effect long after the meditation session, especially with regular practice.

Research on TM and Cortisol Levels

Several studies have examined the relationship between TM and cortisol reduction and provide compelling evidence of its effectiveness.

• Immediate and Long-Term Effects
  Research shows that TM practitioners experience a significant drop in cortisol levels during meditation, and that these levels remain low afterward. A study published in *Hormones and Behavior* found that participants who meditated had lower cortisol levels than those who did not.¹
• Effective for Extreme Stress
  Studies have also examined populations with high stress levels, such as veterans with PTSD, students, and professionals in demanding jobs. A study of veterans with PTSD showed that TM not only significantly reduced cortisol levels but also improved overall psychological health.³

Conclusion

Transcendental Meditation has a significant and positive impact on cortisol levels, making it a powerful tool for stress management and improving overall health. By promoting a state of deep relaxation and alertness, TM helps lower cortisol levels both immediately and over the long term. This makes TM a valuable, natural, and non-invasive practice for anyone seeking to reduce stress and improve well-being.
