A leading dermatologist has issued a stark warning to office workers about the dangers of using portable heaters under their desks. Dr Abigail Waldman, a Harvard Associate Professor and board-certified dermatologist, cautions that this practice can lead to a serious and difficult-to-treat skin condition known as erythema ab igne (EAI), or “toasted skin syndrome”.
In a recent social media post, Dr Waldman, who is known as “Dr Abby” to her 521,000 TikTok followers, explained that she would never use a space heater so close to her skin. “It can result in this,” she said, referring to EAI, a reddish-brown rash and hyperpigmentation caused by chronic heat exposure.
EAI was once commonly seen in the elderly who sat too close to open fires or electric heaters, before central heating became widespread. However, the condition can still occur in people exposed to heat from other sources, such as car heaters, heated furniture, or repeated use of hot water bottles.
Symptoms of EAI can range from a mild, red rash to marked redness and even skin thinning, along with itchiness and a burning sensation. Dr Waldman warns that the condition can be “really difficult to get rid of once you get it.”
The dermatologist also advised against other winter habits that can be harmful, such as making your bed immediately after waking up (which disturbs dust mites) and using tanning beds.
Experts recommend quickly stopping or significantly reducing heat exposure if EAI symptoms develop. While the condition usually improves over weeks or months, the discoloration of the skin may persist. In some cases, a biopsy may be necessary to rule out other issues or early signs of cancer.
Dr Waldman’s warnings highlight the importance of being cautious with portable heaters and other heat sources, especially when used in close proximity to the skin. Office workers and others who rely on space heaters are advised to reconsider this practice and prioritise their long-term skin health.
