Holistic Support for your Immune System

By Michele Chevalley Hedge

During a time when people are waitlisted for a vaccination, stocking up on hand sanitizer and face masks to improve their external defences against viruses and other illnesses, it is also important to consider ways to reinforce our internal natural immunity.

Your immune system relies on your lifestyle. Stress management, good sleep, healthy nutrition, and regular physical activity are all part of this puzzle.

Stress and Immunity

Stress can increase an individual’s susceptibility to illness after exposure to infectious microbes.  Stress can disrupt your antibody mediated and cellular responses.  This stress can be real stresses (financial, death, losing a job) or simply your perceived stresses from negative self-talk. Studies show that people with high perceived stress, emotional reactivity, and negative emotions are at greater risk of acute respiratory infections.  (1)

Stress happens every day to everyone. We need to learn to manage it because we cannot prevent it.  Mindfulness meditation and a gratitude practice cost nothing and can reduce your cortisol and change your mindset in minutes.

Mindfulness doesn’t require sitting on a rock and staring at the moon.  It can be as simple as sitting and breathing slowly without distractions for 15 minutes. The research in this area of wellbeing is only just beginning, but a recent study showed that a two-month mindfulness course produced a reduction in acute respiratory illness and benefits on the immune system. (2)

The practice of gratitude seems ‘airy -fairy’ to many people, but research also suggests links to positive emotions, happiness and hope.  This shifts us away from stress and negativity – a key predator in poor sleep and lower immunity. (3)

Sleep and Immune Function

Sleep should be at the top of your wellbeing priorities.  A human’s mental and physical health begins to falter after just 24 hours of sleep deprivation and can kill you within 11 days.   Poor sleep can impact the immune system by decreasing our natural killer cells – our army against viruses.

Healthy meals, bedtime routine, blue light exposure and more play a factor in promoting deep, quality sleep.   Include nutrition that has amino acids such as tryptophan, the precursor to serotonin, our happy hormone, and melatonin, our sleep hormone. Boom!

There is important research emerging on the relationship of sleep and vaccinations. Growing evidence suggests that sleep plays an important role in immunological memory, including antibody responses to vaccination. Shorter sleep durations, averaged over the collection period, was associated with fewer antibodies from the vaccination. These studies have been conducted with the influenza vaccination and will spark further research into the COVID vaccination and antibodies. (3)

Real Food, Exercise, and Immune Function

Eating nutritious food often leads to exercising more and vice versa.  The benefits are profound, both mentally and physically. One of the outcomes is often maintaining a healthy body weight.  Higher body weight and obesity have been associated with an increased risk of respiratory infections. Is this a perfect storm when we have an obesity pandemic already occurring? (4)

Whilst exercising during a time of isolation and restrictions may not ideal, it is still essential.   Research suggests that up to 40% of ‘normal weight’ adults have excess body fat.  It is that fat that is associated with inflammation, CVD, metabolic abnormalities, and poor immune systems.

You do not need to run 5K or spin for an hour. Even moderate exercise can improve your innate immunity and provide protection against viral infections.  (5) Internet videos and exercise apps have proven to be an isolator’s best friend for movement over the last 12 months.

Nutrition and what we eat will become paramount in prevention of all diseases in the future.  This decade there will be a spotlight on nutritional research and prevention of disease in a new proactive world.  In this odd time when there are so many things we cannot control – but we can control how we feel ourselves. Eating a whole food diet, full of antioxidants, fibre, vitamins and minerals, and naturally low in added sugar, will support a robust immune system.  A well-rounded diet, with minimal packaged and processed foods will provide key immune nutrients such as Vitamin D, Vitamin C, zinc and iron.
