You must have suffered so much from the terrible vicious cycle that comes after a brief moment of relief from nasal spray. Modern medicine refers to this as 'rhinitis medicamentosa,' which mainly occurs when nasal sprays containing nasal decongestant ingredients are used excessively. The 'vasoconstrictor' components, mainly ephedrine, pseudoephedrine, and oxymetazoline, in these sprays rapidly constrict the blood vessels of the nasal mucosa, reducing swelling and resolving nasal congestion. However, this effect is only temporary; once the drug effect wears off, our body triggers a 'rebound' effect to dilate the blood vessels again.
The problem does not end here. As these rebound effects repeat, the blood vessels of the nasal mucosa gradually weaken and lose their ability to self-regulate. Eventually, tolerance and dependence develop, causing the nose to swell and become more severely congested unless the medicine is sprayed. It is just like a dam gate breaking down after being forced open and shut repeatedly. Long-term use of a nasal decongestant impairs the ciliary movement of the nasal mucosa, making it difficult to discharge waste from the nasal cavity and potentially inducing chronic inflammation. In severe cases, it may lead to critical complications such as mucosal atrophy, anosmia, and nasal septal perforation.
Even more important is the impact that excessive use of these nasal sprays has on our body's autonomic nervous system. The autonomic nervous system is divided into sympathetic nerves and parasympathetic nerves, regulating bodily functions beyond our conscious control, such as heartbeat, digestion, and respiration. Vasoconstriction and dilation of the nasal mucosa are regulated by this autonomic nervous system, and nasal decongestants produce effects that stimulate the sympathetic nerve. If external stimuli continually break this balance, the autonomic nervous system itself is disrupted, which can affect not only the nose but overall systemic condition. Being unable to sleep at night due to nasal congestion and feeling anxiety may also not be merely an issue of the nose. Our body is a single organism, so when the nose struggles, the lungs struggle, and when the lungs struggle, the autonomic nervous system also struggles. Now, rather than rushing simply to unclog the nose, restoring the body's natural self-recovery capacity to reclaim fundamental lung function and autonomic nervous system balance is of the utmost importance. This whole process is also about trusting our body's recovery ability, which has been scientifically proven.
