The Serious Consequence Of Being Overstressed

Article by Nathan Morris, MD

Most of us know what stress feels like—tight shoulders, a racing mind, trouble sleeping. But what many people don’t realize is that chronic, unrelenting stress is one of the most powerful accelerators of aging. It affects nearly every organ system, fuels inflammation, and increases the risk of almost every major chronic disease.

The body actually needs stress. In short bouts of stress like strenuous exercise, it adapts to that stress and makes us stronger and more resilient.  In acute situations, it helps us focus, prepare for fight or flight with increased  adrenaline, and kicks off our immune system in case we get bit by the tiger it thinks is chasing us.  When the stress episode  is done then our body is supposed to  go back into our most healthy state, that of calm.  It is in the calm state where our immune system can fight cancers that may pop up, our blood pressure lowers and our heart works less hard, and we repair our bodies.  It is when we don’t go back into that calm state for long periods that we have problems.  It is the slow, steady drip of pressure from work, finances, caregiving, medical issues, or constant digital stimulation that causes the stress response to become toxic.

How Stress Works-And What Goes Wrong

As previously mentioned, stress is a natural event in  daily life and helped us survive when a slow reaction or lack of attention would have been deadly.  It is natural.  We have evolved to handle short bouts of stress.  We handle stress by the brain perceiving a threat then sending signals to the body to get ready.  One of the most important systems for stress  starts with a hormone being sent from the brain to the adrenal gland on top of the kidneys which releases both adrenaline and cortisol.  Cortisol is life giving.  Without it we are very sick and cannot function properly and have severe fatigue, but as they say, “too much of a good thing, is not a good thing”. 

Chronic exposure to excessive amounts of stress hormones like cortisol are eventually aging and lead to many diseases.  The problem lies in that most people are a little too used to stress and are not quite used to not being stressed.  Unfortunately, the cortisol levels will eventually become dysregulated, where they can constantly be  high causing anxiety, high blood pressure, and insomnia or drop low and cause severe fatigue and depression as  the dominant symptoms.  When it is chronically low it is in layman’s term often spoken of as adrenal fatigue or medically, HPA axis dysfunction.  The good news for  both high and low cortisol is that they are very treatable in functional medicine.

Chronic Stress and Aging

It is important to address  chronic stress as it makes us age faster than almost any other the we encounter besides an ultraprocessed diet.  Stress ages us through the following processes

1. Mitochondria-the tiny energy factories inside every cell are important to aging and overall health.  Stress hormones and inflammation impair mitochondrial function, reducing energy output and increasing oxidative damage. Oxidative damage is what ages us.  Oxidative damage also contributes to fatigue, brain fog, and even neurodegenerative diseases like Parkinson’s and Alzheimer’s.

2. Shortened Telomeres-Telomeres, the protective caps on our chromosomes, shorten naturally over time. But chronic stress speeds up this shortening process. Studies show caregivers, trauma survivors, and individuals with high perceived stress have dramatically shorter telomeres and show signs of premature aging.

3. Epigenetic Change-Stress alters the way our genes are expressed through chemical changes known as epigenetic modifications. These shifts can push our “epigenetic clock” years ahead, increasing vulnerability to disease.

4. Cellular Inflammation-Chronic stress drives a phenomenon scientists call inflammaging—a low-grade, persistent inflammatory state that contributes to heart disease, diabetes, cancer, dementia, and frailty.

Stress and Other Health Issues

The Brain-Stress shrinks the hippocampus, the brain’s memory center, and impairs the prefrontal cortex, affecting focus, planning, and emotional regulation. Over time, stress increases the risk of depression, anxiety, and cognitive decline.

The Heart-Stress raises blood pressure, stiffens blood vessels, and disrupts heart rhythm. It is a significant, often underestimated contributor to heart attacks and strokes—even in people without traditional cardiac risk factors.

Metabolism-Chronic stress leads to insulin resistance, weight gain in the abdomen, sugar cravings, and elevated triglycerides—classic features of metabolic syndrome.

Immunity-Stress weakens antiviral and cancer defenses and can increase susceptibility to infections. It can also heighten the risk of autoimmune disease by confusing immune regulation.

Gut Health-Stress affects the gut-brain axis, contributing to IBS, bloating, reflux, and especially changes in the microbiome. It also increases intestinal permeability, sometimes called “leaky gut,” which feeds inflammation.

Hormones-Chronic stress suppresses reproductive hormones in both men and women, contributing to low libido, irregular cycles, fertility issues, and low testosterone.

In many ways, stress is the unseen hand behind conditions we often blame on “getting older.”

What Do We Do with Stress?

The first step is identifying the effects of chronic stress which is harder than it seems because many of us think of these issues as “normal”

• Fatigue, especially in the morning
• Frequent infections or slow recovery
• Poor sleep or waking at 2–3 a.m.
• Brain fog, forgetfulness
• Digestive issues
• High blood pressure or rapid heart rate
• Emotional overwhelmed on the daily

The next step is doing something about it.  As Hans Selye said, “It’s not stress that kills us;it is our reaction to it”

1. Lowering Physiological Stress
• 8 hours of sleep and in bed by 10 PM
• Anti-inflammatory nutrition (limit processed foods and eat more fruits and vegetables)
• Supplements such as magnesium, L-theanine, omega-3s, and adaptogens like ashwagandha 
• Exercise and strength training (moderation is key)

2. Resetting the Nervous System
• Breathwork, especially slow 4–6 breathing
• Heart rate variability training
• Sauna, cold exposure, nature immersion

3. Psychological Strategies
• Mindfulness and meditation-10 mins a day works
• Counseling 
• Setting healthy relationship boundaries
• Reducing digital overload (big one)

4. Social Connection
Humans are wired for connection. Strong relationships buffer the effects of stress and are consistently linked with longer life expectancy.

Wrap Up

Stress is a part of everyone’s daily life.  How we perceive it by being mindful, and then what we do about it will determine if it is a healthy part of our life or a detrimental one.
