When she woke up that morning, she thought the strange purple-marbled pattern on her legs was just “a little rash.” But within minutes, the burning sensation started — and by the time she arrived at urgent care, nurses were asking her the same question over and over:

“Did you sleep with a heating device on your skin?”

The truth stunned her.

Like millions of people during colder nights, she kept a space heater pointed directly at her bed, letting the warm air hit her legs for hours. It felt comforting… until her skin reacted in a way she never expected.

Doctors diagnosed her with Erythema Ab Igne — also known as “toasted skin syndrome” — a condition caused by prolonged exposure to heat sources like space heaters, heating pads, electric blankets, laptops, or even sitting too close to fireplaces.

It doesn’t hurt at first.
It doesn’t itch.
But over time, the skin becomes mottled, discolored, and damaged — and if ignored, can lead to long-term pigmentation changes and even precancerous lesions.

She never imagined something so simple and common could leave her legs looking like this.

Today, she’s sharing her story to warn others:

“Don’t sleep with direct heat on your body. I wish I knew sooner.”

Doctors say prevention is simple:
Keep heaters at a safe distance, avoid falling asleep with a heating pad on, and use blankets instead of direct heat whenever possible.

A small change could prevent a very big problem.
