Seasonal ailments and our immune system
Respiratory tract infections are much more frequent during the autumn and winter months. The cold, humidity, higher rate of pollution, and easier transmission of high viral and bacterial loads, reduces the motility of the cilia lining the bronchi, thus slowing or blocking the outward flow of secretions. This mechanism facilitates the build-up of secretions in the respiratory tract. Impaired defence mechanisms are in fact the underlying cause of colds and flus (common cold, influenza, tracheitis, laryngitis, sinusitis).
When our defences are low, for example following a simple change in temperature, or after exposure to cold and humid air or wind, we may instantly feel a general sensation of cold, overall discomfort, chills, and high temperature. We get a runny and possibly blocked nose. We may experience difficulty swallowing and hoarseness with an altered voice, dry or productive cough.
Hence why we should start thinking about building up a solid immune system against external agents, adapting our lifestyle and adopting suitable protective measures. Those who are weak, debilitated or fragile tend to become easy prey for dangerous external influences. This is precisely why it is important to adopt measures able to optimise our immune system’s defences.
Various nutritional supplements (Lactoferrin), medicinal plants (Echinacea purpurea, Echinacea angustifolia, Fermented papaya), mineral elements (Zinc), and vitamins (Vitamin D) can be helpful in strengthening our defences and protecting the upper airways.
