Proper incense at home makes people feel happy, elegant and comfortable. But burning incense indoors for a long time is unhealthy, especially when the doors and windows are closed. Because whether it is incense made of agarwood, benzoin and sandalwood, or thread incense made of chemical essence and aromatic plants, long-term incense will not only consume some indoor oxygen, but also do more harm to patients with cor pulmonale and asthma, and may cause recurrence or aggravation of the disease.

Precautions for indoor incense: just order 1 or 2 sticks of incense at a time, especially in the bedroom, which is not suitable for long-term incense, not to mention using inferior incense. If there is incense, pay attention to open the window to keep the air circulating normally.
