Introduction

Long-term use of essential oils may damage the olfactory system, leading to reduced sensitivity of smell and, in severe cases, loss of olfaction. If the essential oils used are toxic or irritating, prolonged use can cause certain harm to the liver and kidneys. Some essential oils contain ingredients that may cause photosensitivity; if exposed to sunlight after application, the skin may darken and even develop skin cancer.

If essential oils are improperly handled or used at excessive concentrations, they may cause irritating damage to the human respiratory system.

1. Prolonged use of essential oils may damage the olfactory system, leading to reduced sense of smell; in severe cases, it could result in complete loss of olfaction.

2. Long-term use of essential oils increases the risk of developing allergic rhinitis. The fragrance of essential oils is often strong and pungent; prolonged exposure may increase the likelihood of allergic rhinitis and asthma. If symptoms of allergic rhinitis occur, prompt medical attention is necessary.

3. If toxic or irritating essential oils are used over a long period, they may cause harm to the liver and kidneys.

4. Some essential oils contain components that can cause photosensitivity. After application, if the skin is exposed to sunlight, it may darken or even develop into skin cancer.

5. Long-term use of essential oils may also lead to endocrine disruption.

Essential oils are highly concentrated substances and should never be ingested. Pregnant women should not use essential oils casually, especially those known to have stimulating effects on both mother and fetus, which are strictly prohibited. Essential oils must always be diluted before use. Additionally, they should be stored in dark glass bottles, kept in a cool place away from direct sunlight. Before use, a patch test should be performed on the inner arm to check for allergic reactions.

Elderly individuals with underlying conditions such as hypertension or chronic kidney disease, or those with severe respiratory infection symptoms (such as high fever, sore throat, and difficulty swallowing), should avoid consuming light soy sauce.

Is there a relationship between upper respiratory tract infections and formaldehyde?

If one is exposed to an environment with excessive formaldehyde levels (such as a newly renovated house or areas with substandard furniture) over a prolonged period, formaldehyde can continuously irritate the nasal and pharyngeal mucosa, leading to mucosal congestion and reduced resistance. Under these conditions, exposure to viruses or bacteria makes upper respiratory tract infections more likely, and after infection, mucosal inflammation tends to be more pronounced, resulting in worsened symptoms such as nasal congestion and sore throat.
