1. Respiratory Irritation

Inhaling smoke from burning incense sticks can cause irritation in the respiratory system, leading to coughing, sneezing, or even exacerbating conditions like asthma or allergies. 

2. Air Pollution

Incense smoke can release harmful pollutants such as carbon monoxide, benzene, and formaldehyde, contributing to indoor air pollution. 

3. Allergic Reactions

Some people may be sensitive or allergic to certain ingredients in incense sticks, leading to skin rashes, itching, or other allergic reactions upon exposure. 

4. Headaches

The strong scent of incense sticks may trigger headaches or migraines in some individuals, especially if they are sensitive to strong odours. 

5. Potential Carcinogens

Some studies suggest that long-term exposure to certain chemicals emitted by burning incense sticks, such as benzene and formaldehyde, may increase the risk of cancer, although more research is needed to confirm this link.
