Nonstick cookware ranks as a kitchen staple for health-conscious home cooks seeking to use less oil, clean up easily, and simplify everyday cooking. However, when nonstick cookware overheats, it releases fumes linked to a condition known as “Teflon flu.” The good news is that experts say this condition is largely preventable through a few simple cooking habits that can dramatically reduce risk.

Teflon flu, also known as polymer fume fever, occurs when people inhale fumes from overheated nonstick cookware. The issue involves polytetrafluoroethylene (PTFE), the nonstick coating commonly sold under the Teflon brand name. PTFE is generally considered safe during normal cooking, but it begins breaking down at temperatures above 500°F.

According to the National Capital Poison Center, several hundred suspected cases were reported to U.S. poison centers in 2023. ABC News reported this as the highest yearly total since 2000, with more than 3,600 suspected cases reported over the past two decades. Experts believe Teflon flu is underreported because symptoms often resemble a cold or seasonal flu.

Recognizing Teflon Flu Symptoms

Most people develop symptoms within 12 to 24 hours after exposure to overheated nonstick cookware fumes. Common Teflon flu symptoms include fever and chills, headaches and body aches, fatigue, coughing, chest tightness, shortness of breath, and airway irritation. Symptoms usually improve within one to three days, but people with asthma or other lung conditions may experience more serious breathing problems.

In rare cases involving severe overheating or prolonged exposure in enclosed spaces, significant lung damage can occur. Dr. Darien Sutton, an emergency medicine physician, told Good Morning America that caution is important with PFAS-containing products like PTFE.

“We don’t yet know the long-term effects, but we do know that these chemicals, these PFAS, are associated with health conditions like thyroid abnormalities, certain cancers, like kidney cancer, as well as certain problems with infertility,” Sutton said.

Common Cooking Mistakes That Cause Overheating

A few common cooking habits sharply increase the risk of releasing PTFE fumes. Preheating an empty nonstick pan is the biggest mistake. Without food or oil absorbing heat, pans can quickly exceed safe temperatures. Other risk factors include cooking on high heat or broiling, using scratched, chipped, or peeling cookware, and failing to maintain proper ventilation during cooking.

Mother’s Brush With Death Highlights Sepsis Dangers

As health awareness grows around lesser-known conditions, Audrey Leishman, a Virginia Beach mother, shares her harrowing brush with death to educate others about sepsis. In 2015, the then-31-year-old healthy woman thought she had contracted the flu while caring for her sons, then 19 months and 3 years old, while her husband traveled. What began as typical flu-like symptoms rapidly spiraled into a severe sepsis case that left her in the ICU for 10 days, including five days in a medically induced coma.

Leishman’s ordeal began innocently one evening when she started feeling achy, feverish, and cold, symptoms she attributed to standard influenza since she had never contracted the flu before. As days passed, her condition deteriorated rapidly, with her fever spiking higher and severe stomach issues developing. She experienced random joint pain in her right elbow and left big toe, which confused her since she hadn’t injured herself.

“At one point, I actually thought I was going a little bit crazy, because my right elbow and left big toe started hurting – it was the most random thing. I hadn’t injured myself,” she said. “I was really confused as to what was going on.”

Critical Delays in Diagnosis

When Leishman became too weak to care for her sons and started having nosebleeds, her friend insisted she see a doctor. At Urgent Care, her temperature and heart rate measured abnormally high while her blood pressure dropped dangerously low. Emergency responders transported her by ambulance to the emergency room.

Although today’s hospitals have improved sepsis recognition protocols, Leishman noted that awareness was far less developed in 2015. Doctors initially suspected autoimmune diseases and conducted numerous tests before arriving at the correct diagnosis. The sepsis ultimately turned into acute respiratory distress, requiring intensive intervention to save her life.

Now recovered, Leishman, who is married to professional golfer Marc Leishman, dedicates herself to raising awareness about the condition through her nonprofit organization, the Begin Again Foundation. She has also written a children’s book aimed at helping families recognize the warning signs.

Rugby Player Champions Encephalitis Awareness

In another powerful story of raising awareness for misunderstood medical conditions, Wales scrum-half Aled Davies honors his late father Huw by writing “Dad” on the tape he wears during every rugby match. Davies was just 14 years old when his father began exhibiting debilitating symptoms that would eventually be diagnosed as encephalitis, a rare neurological condition involving inflammation of the brain.

“It started off with flu-like symptoms which he had all week. On the Friday he was sleeping in bed and he went into a seizure,” Davies tells WalesOnline.

The family took Huw to the hospital, but doctors discharged him within hours. By Saturday morning he still wasn’t fully recovered, prompting Davies’ mother to take him back, only to be discharged again. By Saturday afternoon he had become delirious, nearly walking through a window he mistook for a door in their old farmhouse.

The Critical Moment of Collapse

Davies vividly remembers his father collapsing directly in front of him and experiencing seizures again, prompting an emergency call that landed his father in the high dependency unit at Glangwili Hospital in Carmarthen. Following further investigations at Morriston Hospital’s intensive care unit, doctors officially diagnosed encephalitis.

Encephalitis is an inflammation of the brain caused either by an infection invading the brain or through the immune system attacking the brain in error. The condition affects three people every minute globally, yet many people remain unaware of its existence, leading to dangerous delays in diagnosis.

As part of his ambassador role with Encephalitis International, Davies works tirelessly to raise awareness and educate people about critical warning signs. Key symptoms include flu-like symptoms, loss of consciousness, acute headache, memory problems, emotional and behavioral changes, and seizures. His father received treatment with a drug called Acyclovir, which helped manage the condition, though life changed dramatically for the Davies family.

The Common Thread: Early Recognition Saves Lives

These three stories highlight a common thread: conditions that mimic flu symptoms often represent far more serious medical emergencies requiring immediate attention. Whether dealing with Teflon flu from overheated cookware, sepsis from bacterial infections, or encephalitis from brain inflammation, early recognition proves critical to preventing severe complications or death. Medical professionals emphasize that anyone experiencing unusual symptom combinations or rapid deterioration should seek emergency care rather than assuming they have a common cold or seasonal flu.

Simple prevention measures can protect households from Teflon flu, including never preheating empty nonstick pans, cooking on medium or low heat, replacing damaged cookware, ensuring proper kitchen ventilation, and never leaving nonstick pans unattended on burners. For sepsis and encephalitis, knowing the warning signs and seeking immediate medical attention when symptoms worsen dramatically can mean the difference between recovery and tragedy.
