What Is Stress? Understanding the Mind-Body Response
Stress is the body's response to a challenge or demand. It is a normal reaction that helps us respond to pressures. When faced with a difficult situation, your body releases stress hormones like cortisol and adrenaline, which prepare you to either “fight” the problem, “flee” from it, or “freeze” in response. This instinct was vital for survival in ancient times but, still serves a purpose today.
For instance, an athlete might experience stress before a competition, pushing them to perform better. Similarly, a student may feel pressured before an exam, prompting them to study harder. However, stress becomes problematic when it is constant, lasting weeks, months, or even years. Over lengthy periods of time, stress can wear down the mind and body leading to burnout, exhaustion, and serious health complications.
Common Causes of Stress in Everyday Life

Stress triggers vary from person to person, but common causes can include any one or even a combination of the following:
Work and School Pressure: Deadlines, exams, heavy workloads, and job insecurity can all contribute to stress.
Financial Worries: Struggling to pay bills or managing debt can be a constant source of stress and anxiety.
Health Issues: Dealing with illness, chronic pain, or injury can place a heavy emotional burden on someone.
Relationships: Conflicts with family, friends, or romantic partners can cause significant emotional distress.
Major Life Changes: Moving to a new home, starting a new job, getting married, or having a baby can all create stress, even if they are positive changes.
Unexpected Events: Sudden loss, accidents, or world events (such as pandemics or natural disasters) can be overwhelming and trigger long-term stress.
Personal Expectations: The pressure to meet personal goals, such as achieving career success, maintaining a certain body image, or excelling in a hobby, can lead to stress.
Not everyone experiences stress in the same way, and what is stressful for one person may not be for another. Some people handle challenges with ease, while others find even minor disruptions difficult to cope with. Factors such as personality, upbringing, past experiences, and available support systems all play a role in how an individual experiences and manages stress.
Physical, Emotional, and Behavioural Symptoms of Stress
Stress manifests in various ways, affecting the body, emotions, and behaviour. Recognising these signs early can help prevent it from escalating.
Physical Symptoms of Stress
Stress does not exist only in the mind; it has real effects on the body. Some common physical symptoms include:
Headaches
Muscle tension or pain (especially in the shoulders, neck, or back)
Fatigue and low energy
Trouble sleeping or sleeping too much.
Stomach problems, such as nausea or digestive issues

Nervous habits like nail-biting or fidgeting
Becoming overly controlling or perfectionistic
When Does Stress Become Chronic or Harmful?

As a reminder, short-term stress can help you react quickly in emergencies or push you to achieve goals. But when stress becomes chronic, it can harm both mental and physical health.
Imagine stress as carrying a backpack filled with bricks. At first, carrying it for a short distance might not feel too bad. But if you keep carrying it day after day without putting it down, it will start to wear you down.
Over time, chronic stress can contribute to serious health problems and is known to be one of the leading causes of all sicknesses, illnesses, and diseases.
Acute vs. Chronic Stress: Key Differences and Effects
Understanding the difference between acute stress and chronic stress can help determine when stress is becoming harmful.
The main difference between acute stress and chronic stress lies in their duration, intensity, and effects on the body and mind.
Acute Stress (Short-Term Stress)
Definition: A temporary response to an immediate challenge or demand.
Causes:
A work deadline
Public speaking
A near-miss accident
An argument with a friend or family member
Effects:
Rapid heartbeat, sweating, muscle tension
Increased alertness and focus
Temporary feelings of anxiety or nervousness
Impact:
Often beneficial, improving reaction time and motivation
Usually resolves quickly once the situation is over
Chronic Stress (Long-Term Stress)
Definition: Ongoing stress that lasts for weeks, months, or even years.
Causes:
Financial struggles
A demanding job with no relief
Ongoing relationship conflicts
Living in a stressful environment
Effects:
Weakened immune system, leading to frequent illness
Increased risk of high blood pressure and heart disease
Anxiety, depression, and emotional exhaustion
Sleep disorders and digestive problems
Impact:
Harmful over time, leading to burnout, physical illness, and mental health issues.
Requires long-term stress management strategies.
Key Takeaway
Acute stress is temporary and manageable, often providing motivation in short bursts.
Chronic stress is prolonged and harmful, gradually wearing down the body and mind.
Managing chronic stress is crucial to prevent long-term health complications.
Signs It’s Time to Get Help for Stress
While stress is a normal part of life, there are times when it becomes too much to manage alone. It may be time to seek professional support if you experience:

Persistent feelings of anxiety, sadness, or hopelessness. If stress is making you feel emotionally drained and you cannot shake the feeling, professional help can offer guidance and relief.
Physical health problems linked to stress. Chronic stress can contribute to high blood pressure, frequent headaches, digestive issues, or other physical symptoms that should not be ignored.
Difficulty managing daily responsibilities. If stress is affecting work, relationships, or personal tasks, intervention can help restore balance.
Unhealthy coping mechanisms. Increased substance use, withdrawal from loved ones, or self-destructive behaviour may indicate a need for help.
Trouble sleeping or chronic fatigue. If stress is keeping you up at night or leaving you constantly exhausted, professional guidance can help address underlying issues.
Feeling overwhelmed to the point of crisis. If stress leads to thoughts of self-harm or suicidal feelings, immediate help is crucial. Crisis helplines, therapists, or medical professionals can provide urgent support.
Talking to a therapist, counselor, or support group can provide valuable tools to cope with stress in healthy ways. Mental health professionals can help you build resilience and navigate challenges more effectively, leading to improved overall well-being.

Answers to Common Questions Canadians Ask About Stress
Can stress affect your memory or ability to concentrate?
Yes. High levels of stress or prolonged stress can impair cognitive functions like memory, decision-making, and focus. The brain’s prefrontal cortex, responsible for concentration and reasoning, can be disrupted by chronic stress, leading to forgetfulness and mental fog.
Is it normal to feel irritable or angry when stressed?
Absolutely. Irritability is a common emotional symptom of stress. When stress levels are high, your brain becomes less tolerant to external stimuli, making small annoyances feel overwhelming and triggering emotional outbursts or mood swings.
What is burnout, and how is it different from stress?
Burnout is a state of emotional, mental, and physical exhaustion caused by prolonged stress often related to work or caregiving. Unlike everyday stress, burnout leads to feelings of hopelessness, detachment, and reduced performance. It’s a sign that your coping system is overwhelmed and needs serious intervention.
Can stress cause physical pain even when I’m not feeling anxious?
Yes. Stress can trigger muscle tension, headaches, back pain, and even gastrointestinal discomfort even without obvious anxiety symptoms. This is due to prolonged activation of the body’s stress response, which can cause inflammation and tighten muscles, especially in the neck, shoulders, and lower back.
How does stress affect the immune system long-term?
Chronic stress can suppress immune function, making you more vulnerable to colds, infections, and slower recovery times. Elevated cortisol levels over time reduce the body’s ability to fight off pathogens and heal properly.
Does long-term stress lead to autoimmune disorders?
Research suggests that chronic stress can exacerbate or contribute to the development of autoimmune diseases like lupus, rheumatoid arthritis, or multiple sclerosis by causing prolonged inflammation and dysregulating immune response.
Can stress cause hair loss or skin problems?
Yes. Chronic stress can worsen or trigger skin issues like eczema, acne, and psoriasis. It can also lead to telogen effluvium, a condition where stress forces hair follicles into a resting phase, causing noticeable hair thinning or loss.
Can stress lead to weight gain or loss?
Yes. Stress can disrupt appetite and metabolism. Some people gain weight due to increased cortisol and emotional eating, while others lose weight due to loss of appetite or digestive issues. Both are common reactions to long-term stress.
Is shortness of breath from stress dangerous?
Stress-induced shortness of breath, also called hyperventilation, is usually harmless but it can feel alarming. However, if you're unsure whether it’s from stress or a medical condition (like asthma or heart issues), it's best to seek medical evaluation.
Can stress mimic any other health conditions?
Yes. Stress can mimic symptoms of heart disease, IBS, thyroid problems, and more. Chest tightness, digestive issues, and fatigue caused by stress are often mistaken for other conditions highlighting the importance of a proper medical assessment.
