8 cooking habits that cause your family to eat twice as many carcinogens

7. Always keep the kitchen window closed.

Some people, especially older people, believe that closed windows help the extractor hood work better. In reality, this reduces air circulation and causes harmful gases to accumulate in the kitchen.

The correct way is  to use the extractor hood and open the window at the same time to ensure proper airflow and complete gas combustion, thus reducing toxic emissions.

8. Do not dry the vegetables before putting them in the pan.

If you often cook vegetables while they’re still wet, you should stop doing so. When water from the vegetables hits hot oil, it causes splashing and drastically increases PM2.5 (fine particulate matter) levels, even more so than with deep frying.

This not only increases the risk of burns from oil splashes, but also significantly impairs the air quality in your kitchen.
