Can you use mosquito repellent incense when you have a cold?
It is generally not recommended to use mosquito repellent incense when you have a cold, as it can easily irritate the respiratory tract and worsen symptoms. If symptoms persist or become severe, medical attention should be sought immediately. The analysis is as follows:

The burning of mosquito incense releases smoke and volatile compounds that disperse into the air and may irritate the respiratory system. When you have a cold, your respiratory tract is already infected and inflamed; additional irritation may exacerbate symptoms such as coughing and sore throat, causing further discomfort.
Mosquito incense typically contains various chemical components, such as fragrances, dyes, and preservatives, which may negatively affect the sensitive respiratory system. During a cold, the body's immune system is already fighting off a virus, so exposure to substances that could trigger allergies or irritation should be avoided to prevent worsening symptoms or prolonging recovery time.
Combustion byproducts from mosquito incense may also include harmful substances such as benzene and formaldehyde. Prolonged exposure to these substances may pose health risks. When suffering from a cold, the body’s ability to adapt to external environments is reduced, so it is important to avoid environments that could negatively impact health.
During a cold, patients should keep indoor areas well-ventilated, which helps remove viruses and harmful substances from the air and supports recovery.
