The impact of stress on your mental health

In today’s society, many things can be a source of stress. So how can you limit the impacts of stress on your physical and mental health?

The mental health of Canadians is now three times poorer than it was prior to the pandemic, as reported by the Canadian Mental Health Association. Statistics Canada estimates that 1 in 4 Canadian adults experienced severe symptoms of depression, anxiety or PTSD in 2023.

What is Stress?

Stress is a reaction to change or to situations that we perceive to be threatening. It can be associated with positive experiences (marriage, a birth, etc.) or negative experiences (financial worries, job loss, death of a loved one, etc.).

It’s important to recognize that the way you feel about a situation plays an important role in triggering stress. A situation that is stressful for one person might not be for another, and vice versa. The causes and intensity of stress involve some individual variability.
 

How Does Stress Affect Mental Health?

Stress has a psychological impact that can manifest as irritability or aggression, a feeling of loss of control, insomnia, fatigue or exhaustion, sadness or tears, concentration or memory problems, or more.

Continued stress can lead to other problems, such as depression, anxiety, or burnout. Good stress management improves your quality of life and mental health.


Look For Common Symptoms of Stress

 

Based on the Psychological First Aid (PFA) program by the Canadian Red Cross, the common signs of psychological stress include:

  • Physical: Sleep problems or insomnia, headaches, tiredness, fatigue, stomach aches.
  • Mental: Difficulty concentrating, memory issues, lack of focus.
  • Emotional: Irritability or mood changes, anxiety or excessive worry, emotional exhaustion, feeling overwhelmed or out of control, sadness.
  • Spiritual: Loss of meaning or faith.
  • Behavioural: Risk-taking, substance use, recklessness.
  • Interpersonal: Withdrawing from others, conflict with others, isolation.
Chronic stress can increase the risk of anxiety disorders, depression, and burnout.


How Does Stress Affect Physical Health?

A report from the Inaugural Canadian Stress Research Summit points out how chronic stress can harm not only your mental health, but also your physical health. It shows that ongoing or repeated stress can lead to a higher chance of developing various neurological, psychological, and physical issues throughout life.


Physical Effects of Chronic Stress

 

Our body activates a long-term stress response when we experience prolonged or continuous stress, also called fight-or-fight response. Over time, this may contribute to:

  • Increased blood pressure
  • Headaches or migraines
  • Muscle tension (back pain, neck pain, etc.)
  • Digestive issues (diarrhea, heartburn, stomach ulcers, etc.)
  • Weakened immune function
  • Increased risk of heart disease

How Can I Better Manage My Stress?

The first step in managing stress is finding its cause. Once you have that information in hand, you can look for ways to reduce it. For example, you could end a relationship that brings you more stress than joy or delegate some tasks to your colleagues.

Since stress is a matter of perception, it can be beneficial to work on the way you view things and learn tools and strategies to help navigate different situations. By accepting that it isn’t always possible to control some aspects of these situations, you can focus on taking concrete action. Help from a health care provider may be useful to reframe the way you see stressful situations.


Listen To Yourself

 

Be mindful of your emotions. Recognize your feelings and refrain from making assumptions. Reflect on these questions:

  • Am I tired even though I’ve had enough sleep?
  • Am I easily irritated by other people?
  • Do I feel increasingly critical, cynical, or disengaged?
Recognize your emotions without judgment; this is an important element of self-care. Paying attention to yourself is the initial step towards self-kindness.
