Hormones and Stress: Cortisol, Adrenaline, and the Nervous System

Hormones and Stress: Cortisol, Adrenaline, and the Nervous System

Every moment of stress in your life—whether mild tension or overwhelming pressure—is influenced by a biochemical system designed to protect you. Two hormones play central roles in this response: cortisol and adrenaline. These chemicals drive the activation of your stress mechanisms, sharpen your senses, and help you respond to challenge.

While these reactions are necessary for survival, chronic activation can impact sleep, digestion, mood, immunity, and long-term health. What many people do not realize is that hypnosis and guided mind-body interventions can measurably influence hormonal stress pathways, helping the body return to balance.

This article explores the research behind stress hormones, how they work, and what studies in medical and hypnotherapy journals reveal about the power of hypnotic techniques in regulating the body's stress chemistry.

Understanding the Stress Hormone System

1. Adrenaline: The Fast-Acting Alarm

Adrenaline (epinephrine) is released quickly during perceived threats. It:

• Increases heart rate

• Raises blood pressure

• Sharpens focus

• Mobilizes energy

This is part of the sympathetic nervous system, responsible for the fight-or-flight response.

2. Cortisol: The Long-Term Stress Hormone

Cortisol works on a slower timeline through the HPA axis (hypothalamic–pituitary–adrenal axis). It:

• Regulates metabolism

• Influences memory

• Helps manage inflammation

• Maintains energy supply

While cortisol is essential, chronic elevation is linked to anxiety, burnout, immune suppression, and hormonal imbalance.

What the Research Shows: Hypnosis and Hormonal Regulation

Multiple studies in medical and hypnosis journals show that hypnotic states can influence the body’s hormonal stress response. Here are the most significant findings:

1. Hypnosis Can Lower Cortisol Levels

Early studies such as those by Sachar, Cobb, & Shor demonstrated that during deep hypnotic relaxation, cortisol levels in the blood significantly decreased. In some participants, levels dropped to the lowest in the measured range.

This suggests that hypnosis directly engages and calms the HPA axis.

2. Hypnotic Analgesia Reduces Stress Reactivity

In cold-pressor studies, hypnosis reduced subjective pain and decreased stress-related physiological responses. Although cortisol changes were modest, markers of stress-related inflammation dropped—showing indirect hormonal balancing effects.

3. Imagined Stress Under Hypnosis Alters Hormones

A fascinating study comparing real and imagined stress tasks found that even hypnotically imagined stress influenced cortisol and other hormones such as growth hormone and renin.

The mind’s expectation produced a measurable biological shift.

This reinforces the concept that the body “responds” to hypnotic suggestion as though it were real.

4. Hypnotherapy Lowers Stress Markers in Medical Patients

Studies involving:

• post-cesarean recovery

• menopausal women

• surgical patients

found that hypnotic interventions significantly improved stress symptoms and led to drops in cortisol.

5. Hypnosis May Influence Oxytocin and DHEA-S

Emerging research suggests hypnosis can increase oxytocin, the hormone of bonding and calm, and improve the cortisol/DHEA-S ratio, associated with long-term stress resilience.

How Hypnosis Helps Regulate Hormones

Hypnotic states produce:

• reduced sympathetic activation

• enhanced parasympathetic (rest-and-digest) function

• slowed breathing

• relaxation of muscle tension

• improved vagal tone

These effects signal safety to the brain, reducing the need for cortisol and adrenaline release.

Hypnosis also helps rewire stress patterns through:

• imagery

• suggestion

• reframing

• guided emotional regulation

• nervous system entrainment

Over time, this trains the body to move more efficiently out of stress and into recovery.

Practical Strategies for Supporting Hormone Balance

You can support hormonal resilience by practicing:

1. Slow rhythmic breathing

This calms the autonomic nervous system and reduces adrenaline.

2. Guided hypnosis or self-hypnosis

Even brief sessions create significant physiological shifts.

3. Visualization of safety and calm

This influences the brain’s stress prediction system.

4. Mind-body relaxation techniques

Meditation, progressive relaxation, and breathwork all reinforce parasympathetic dominance.

5. Consistent mental training

Regular practice leads to long-term hormonal regulation.

Conclusion

Cortisol and adrenaline play essential roles in survival, but chronic activation can damage health and well-being. Research in medical and hypnosis journals shows that hypnotic techniques hold measurable power in influencing the body’s stress systems—lowering cortisol, moderating stress reactivity, and promoting long-term resilience.

Through guided focus and intentional relaxation, hypnosis becomes a scientifically supported path to restoring hormonal balance, emotional stability, and a calmer nervous system.
