Doctor's TikTok Video Warns of Hidden Skin Rash from Everyday Heat Sources

A recent TikTok video by Dr. Jen Caudle, a family doctor and medical school professor, has brought attention to a skin condition called erythema ab igne. This rash, caused by prolonged exposure to heat sources, is often overlooked. The video shows a young woman with the characteristic rash on her abdomen, a result of using a heating pad at a high setting for extended periods. "This condition is called erythema ab igne," explains Dr. Caudle in the video, "and it comes from chronic exposure to a heat source." She demonstrates how various heat sources, including laptops and space heaters, can also cause the same reaction. While reassuring viewers that the rash usually fades when the heat source is removed, Dr. Caudle emphasizes that prolonged exposure can lead to permanent skin changes. This video serves as a helpful reminder to be mindful of how long and at what intensity we use heat sources near our skin.
