Dr. Yousefsani Warns of Winter's Silent Threat
Carbon Monoxide Poisoning Risks During Winter
As National Poison Prevention Week unfolds, Dr. Bahareh Sadat Yousefsani, a faculty member and toxicologist at the School of Iranian Medicine, has shed light on the dangers of carbon monoxide poisoning in a recent interview. She stressed the critical importance of adhering to safety precautions when using heating devices during the colder months.

Dr. Yousefsani pointed out that with the arrival of winter, numerous cases of carbon monoxide poisoning are reported each year. This gas, often referred to as the "silent killer," is odorless, colorless, and tasteless, making it particularly dangerous. Carbon monoxide is produced from the incomplete combustion of fuels such as natural gas, oil, and coal, and can lead to symptoms like lethargy, headaches, nausea, dizziness, and even death within a short period.
Highlighting common sources of carbon monoxide, Dr. Yousefsani noted that heaters or water heaters without chimneys, blocked chimneys, and the use of heating appliances in enclosed spaces are significant contributors to poisoning incidents.
To prevent carbon monoxide poisoning, she recommended the following safety measures:
- Ensure the health of chimneys and ventilation before operating heating appliances.
- Avoid using charcoal or picnic gas in tents, cars, or closed rooms.
- Turn off heating appliances without chimneys while sleeping.
- Install a carbon monoxide alarm sensor in homes, particularly in colder areas.
In conclusion, Dr. Yousefsani emphasized that while carbon monoxide is odorless and colorless, it is also a ruthless toxin. By following these simple safety tips, families can protect themselves from this hidden danger.
