There are several reasons why sinusitis changes with the seasons and can worsen with the change of temperature and weather.
Sinusitis (currently called rhinosinusitis) is the inflammation of the tissue that lines the nose and sinuses. This inflammation causes the accumulation of thick mucus inside the sinuses, which is the cause of the characteristic symptoms of this condition: nasal congestion and discharge, facial pain, or pressure, and decreased or loss of smell.
Like many other conditions, sinusitis has a variable incidence depending on the seasons and the corresponding changes in temperature.
The main reason for the increase in episodes of acute sinusitis and exacerbation of chronic sinusitis is the increase in the number of cases of the common cold, because when a common cold lasts for more than 10 days, it is called acute post-viral sinusitis.
Like most viral respiratory infections, the cold shows a clear seasonal predominance with a higher incidence in the cold months. However, various studies have shown that temperature fluctuations should be taken into account rather than absolute temperature levels.
The increase in colds in the autumn and winter is partly due to more time being spent indoors in homes, schools, stores, businesses, etc. The air indoors is often dry and dehydrates the mucous membrane of the nose and sinuses, favouring their inflammation.
Thus, the greater the number of colds, the greater the number of episodes of acute sinusitis, since approximately 10% of colds will evolve into acute sinusitis.
When symptoms persist for more than 3 months, sinusitis is classified as chronic. People with chronic sinusitis have a higher number of exacerbations in the winter months.
Another predisposing factor to suffer from sinusitis is allergic rhinitis. Depending on the substance that causes it, the allergic reaction will occur in one season or another.
Thus, people who suffer from pollen allergies will have more allergic reactions in spring, and mould allergy sufferers, for example, will have more episodes in autumn since, at that time of year, the levels of mould outside are normally at their peak.
Rhinitis favours the development of sinusitis because it causes inflammation of the sinuses and nasal mucosa, preventing the drainage of the mucus that accumulates inside the paranasal sinuses, which becomes purulent and causes the annoying symptoms mentioned above.
Air pollution and climate change alter the flowering and allergen cycle, and air pollution can increase the allergenic potency of pollens, producing a greater number of cases of allergic rhinitis.
Regardless of the cause and time of year, the symptoms of sinusitis can be relieved with products that remove the thick mucus retained in the paranasal sinuses and restore normal function of the nasal mucosa and sinuses.
This is precisely what Nasodren® does. Nasodren is a 100% natural, safe, and effective nasal spray that, through its unique mechanism of action, drains mucus and cleanses the sinuses and nasal passages, relieving sinus symptoms from the first application.
