6 Keys to Understanding Chronic Stress and How to Prevent It

Chronic stress has become a silent enemy of our physical and mental health. Unlike wild animals, humans have the unique ability — and the problem — of getting stressed just by thinking.

But why doesn’t a zebra develop an ulcer, while an office executive does? This article explores how stress works, how it differs in humans and animals, and most importantly, how to reduce its negative effects using educational tools like the Langford Method, which helps children and families develop mental, emotional, and self-care skills from an early age.

1. What is stress and why do we feel it?

The word “stress” originally referred to pressure or tension on an object. Over time, it was adopted in medicine and psychology to describe the physiological and emotional reactions we experience in response to a threatening or demanding situation.

In small doses, stress can be beneficial: it keeps us alert, enhances performance, and prepares us to act. The problem arises when stress becomes chronic, affecting our health, relationships, and overall quality of life.

2. The case of zebras: why don’t they get sick from stress?

Dr. Robert Sapolsky, a neuroendocrinologist at Stanford University, studied wild animals for years and published Why Zebras Don’t Get Ulcers. He explains: when a zebra spots a lion, its body triggers a fight-or-flight response — the heart beats faster, blood flows to the muscles, and energy focuses on survival.

Once the danger passes, the zebra’s system quickly returns to calm. Unlike humans, zebras don’t mentally relive the attack or worry about tomorrow.

Humans, however, are experts at replaying stressful events in our minds. We can get stressed just imagining a future argument, recalling a past failure, or worrying about uncertainty. This leads to prolonged physiological activation that severely impacts health.

3. Psychological stress: can we get sick from our thoughts?

Yes. We don’t always get sick from external events, but from how we interpret and dwell on them. Thoughts like:

• “I’m not good enough”
• “This will never work”
• “What if I fail?”

trigger the same physical stress response as escaping a lion. But because the danger is imagined, there is no clear “escape,” and we enter a loop of chronic stress where the body never fully recovers.

Effects can include:

• Gastric ulcers
• Insomnia
• Anxiety and depression
• Digestive problems
• Immune system disorders

4. Stressed children: a silent reality

Many adults believe children don’t experience stress. The reality is different. Even children aged 4–6 are showing anxiety, chronic frustration, and difficulty managing emotions.

This often happens because they aren’t taught emotional regulation tools early on. They face pressure to perform, are overstimulated, and lack the time or space to develop internal habits of calm, focus, and resilience.

5. How to prevent chronic stress from childhood

This is where the Langford Method comes in: an innovative educational approach that develops mental, emotional, and linguistic habits in children aged 2–10. Through multisensory routines and exercises, the programs help children:

• Develop resilience to frustration
• Cultivate self-control and patience
• Improve concentration and language skills
• Use movement as a tool for emotional regulation

The result: children who are confident, balanced, and prepared to face life’s challenges without falling into chronic stress.

6. Adults: how can we reduce stress and regain balance?

Adults also need tools to change their stress response. Strategies based on neuroscience and educational psychology include:

• Change your internal dialogue: notice negative automatic thoughts and replace them with realistic affirmations
• Practice mindful breathing or daily meditation
• Move every day: physical activity is one of the most effective ways to release accumulated stress
• Prioritize quality sleep: rest is key for processing emotions and regaining balance
• Surround yourself with positive relationships and safe environments

Above all, remember: stress doesn’t come from outside; it comes from how you interpret it.

FAQs

Why do humans suffer from chronic stress while animals don’t?

Humans can think about the past and future, continuously reliving or anticipating dangers.

What illnesses can prolonged stress cause?

Stress can lead to ulcers, hypertension, insomnia, anxiety, chronic fatigue, and autoimmune diseases, among others.

How does the Langford Method help prevent stress in children?

It teaches positive mental and emotional habits, promoting self-control, focus, self-esteem, and emotional regulation.

What can I do today to reduce stress at home?

Conclusion: the solution lies in your thoughts

Unlike zebras, humans often live trapped in our own minds, creating stress where there is no real danger. But unlike zebras, we also have the ability to choose new ways of thinking and acting.

The good news: it can be learned, and the sooner we start, the better.
