Stress is a normal part of life. It is the feeling of butterflies in our stomach on a first date, or exhilaration when we are on a roller coaster or the stress that helps us to meet a deadline or compete for a promotion.
Chronic stress, when we are stressed almost daily, has serious implications on our health. This kind of long-term stress can be from a demanding job, relationships or from our high expectations of ourselves. It can result in feelings of anxiety, irritability, inability to concentrate, frequent colds and flu, pains and aches in the body, low mood, difficulty sleeping, and fatigue.
Clinical data has shown that chronic stress has serious implications for your heart health including an increase in plaque build up, cholesterol imbalance, triglyceride, blood sugar imbalance, inflammation and high blood pressure.
If you ever wondered how stress translates in the body to heart disease, here are three ways that stress negatively impacts your heart health:
1. Stress Increases Blood Pressure and Blood Sugar Levels
When we are stressed our body produces stress hormones including cortisol and adrenaline. These hormones are pumped through the body causing your heart rate to increase. As this happens your body needs more energy, which triggers a release of glucose into the blood. This spikes your blood sugar.
These changes put your body into fight or flight mode. This allows your brain to focus and take action quickly (as if it was being chased by a predator).
In people with chronic stress, this minute of focus can turn into days or weeks resulting in high blood pressure (hypertension) and high blood sugar levels. This response can also lead to a hyper-alertness that makes it difficult to relax or sleep, as well as difficulty focusing on longer or more concentrated tasks.
2. Stress Inflammation and Immunity
Chronic inflammation as a result of an always on, hyper alert stressed state of being also has an effect which activates the immune system causing white blood cells to be activated within our bodies. This immune response may cause damage to the lining of our arteries, reducing NO needed for blood pressure regulation and increasing plaque build up, increasing the risk of heart attack and stroke.
The continuous stimulation of the immune system caused by stress and inflammation can go two ways, the immune system can become overactive which may result in an autoimmune condition or it can become depleted. Leaving our immune defences lowered and our bodies open to pathogens such as bacteria, fungi (yeast) and viral infections including cold sores, mouth ulcers, colds and other viruses.
3. Stress and Nutrient Deficiencies
Stress depletes our body of much needed nutrients. The body needs vitamins like B5 and vitamin C to produce cortisol. To clear up the after effects of stress our body requires antioxidants such as vitamin C, E, A, D and K. Our body also requires magnesium and calcium for contraction of muscles which you will recognise get tense in times of stress.
In addition to the nutrients our bodies need directly to cope with stress, our behaviour when stressed also plays a role. In order to provide our stressed out body with enough energy we will often make unhealthy food choices to get a quick fix of glucose - favouring sugary, processed or high fat foods.
Coping mechanisms such as alcohol and smoking also deplete our body of essential vitamins including B Vitamins and Vitamin C. While high impact exercise (e.g. running it off) can further lead us into fight or flight mode which does not prioritise digestion. This compromised digestion means that even if we eat well, we could struggle to make use of the nutrients in our food.
In addition to dietary changes to support your body’s nervous system, heart, immune and hormonal health, actively putting in place lifestyle supports and learning to manage our stress well is critical to your health. Here are seven practical ways you can actively manage your stress:
