What is Teflon flu? Know the symptoms and how to prevent them

Nonstick pans have taken over the kitchens as they are easy to use and can be cleaned quickly. However, many scientific studies warn against the health problems caused by nonstick cookware. In 2023 alone, more than 250 Americans sought medical treatment due to 'Teflon flu' or 'polymer fume fever,' an inhalation ailment. The coating may break down and release toxic fumes when the nonstick cookware is overheated. Experts say that Teflon flu is caused by these fumes being inhaled. Moreover, researchers note that the chemicals used to make nonstick cookware may lead to serious lung injuries.

What is Teflon?
Teflon is a synthetic chemical containing carbon and fluorine called polytetrafluoroethylene. This is what gives the cookware its non–sticky and frictionless surface, making it extremely convenient to use for cooking.
How does it cause Teflon flu?
Cooking in Teflon-coated pans and cookware was generally considered safe. However, the coating on the pans may disintegrate when it is heated above 500 degrees Fahrenheit (260 degrees Celsius). It then releases a dangerous mix of oxidized and fluorinated substances into the air. Inhaling these harmful fumes leads to physical discomfort and Teflon flu in many.

Symptoms
Fever and chills, fatigue, headache, difficulty breathing, vomiting, chest tightness and joint and muscle aches are the major symptoms of Teflon flu.
Here’s how to use nonstick cookware safely:
Cookware with nonstick coating shouldn’t be overheated. Besides, the pans shouldn’t be heated without food in them as the nonstick surface gets heated up quickly. It is safer to replace nonstick cookware with stainless steel or cast iron vessels.

Make sure that there is enough air circulation in the kitchen. Moreover, switch on the exhaust fan to ensure that the fumes are pushed out. Do not hesitate to replace nonstick cookware if you notice that the coating has come off. Damaged nonstick pans release more toxic fumes, increasing the risk of Teflon fever and other health conditions. Nonstick cookware should be cleaned using soft scrubbers or sponges. Using abrasive aluminium and steel scrubbers can cause scratches on the surface and damage the Teflon coating.
