Exposure to incense can cause what?

1. Respiratory problems: Incense smoke can irritate the lungs and airways, causing coughing, wheezing, and shortness of breath. This is especially true for people with asthma or other respiratory conditions.

2. Allergic reactions: Some people are allergic to the chemicals in incense smoke. This can cause a range of symptoms, including skin rashes, watery eyes, and nasal congestion.

3. Eye irritation: Incense smoke can irritate the eyes, causing redness, watering, and burning.

4. Headaches: Some people experience headaches after being exposed to incense smoke. This is thought to be caused by the chemicals in the smoke triggering the release of histamine, which can lead to inflammation and pain.

5. Nausea: Incense smoke can also cause nausea and vomiting in some people. This is thought to be due to the irritation of the digestive system by the chemicals in the smoke.

6. Cancer: Some studies have linked long-term exposure to incense smoke to an increased risk of cancer, including lung cancer and nasopharyngeal cancer. However, more research is needed to confirm this link.
