But when stress becomes a constant companion it can cause some serious negative consequences on our health. Stress increases the plaque rate and it can accumulate in the arteries. It makes platelets sticky and prone to forming clots that can block these arteries. Stress can also cause arteries to constrict, starving the heart of nourishing blood and triggering chest pain or a heart attack.

Women are particularly vulnerable to the impact of stress on the heart – sorry ladies! That’s why it’s so important that women with heart disease (or its risk factors) should recognize stress and learn how to cope with it in a healthy manner.

“We can all relate to being burnt out, depleted and stressed,” says psychologist Carolyn Fisher, PhD. “But it doesn’t mean we can’t do anything about it.”

What is stress?

Stress can be broadly defined as a threat or demand placed on your body that outweighs your ability to cope with it.

Women tend to become stressed over issues involving home, family life and health-related events, while men are likely to be bothered by finances, work-related issues and relationship problems.

Regardless of the cause, stress sparks our fight or flight response that floods the body with adrenaline. When stress becomes constant, the body remains in alert mode. And perpetually high levels of stress hormones can trigger physiological changes.

Coping styles differ

“Unfortunately, women report higher levels of stress and feel the impact of stress more than men,” says Dr. Fisher.

Women tend to cope by engaging in social activities, such as calling up friends, or sedentary activities, such as reading, watching television or eating.

Men turn to physical activities, such as exercising or playing sports.

“Taking an active role in facing your stressor is healthier and more effective than avoiding it by sleeping, drinking or isolating yourself,” explains Dr. Fisher.

Stress management – how to deal

There are many techniques for minimizing your response to stress:

  • Biofeedback. (This technique teaches you to control your body’s reaction by changing your thoughts and emotions.)  
  • Meditation.
  • Breathing exercises.  
  • Autogenic training. (This practice involves speaking or thinking verbal cues to different parts of your body.) 
  • Progressive muscle relaxation.
  • Mindfulness-based stress reduction.
  • Challenging unhelpful thought patterns.

For maximum efficacy, these techniques should be supported by other good health behaviors.

“Getting enough sleep, eating right and exercising makes us feel more armed and ready,” says Dr. Fisher.

Whatever stress management techniques you choose, you will need to practice them regularly to prevent stress from building up.

“It must become part of your daily routine, like bathing or brushing your teeth,” says Dr. Fisher. “But think of the benefits. Once the stress is gone, who’s to say another huge stressor will never happen again? At least you’ll have the tools to prevent it from taking a detrimental toll on your health.”
