Manga artist says ChatGPT advised rest at home with a rehydration drink for heatstroke symptoms, before IV drips in hospital on day three (first-person)
On 8 July 2026 a manga artist posted a comic on X about getting heatstroke. One panel shows ChatGPT's reply to the author's question: drink OS-1 rehydration solution, keep cool and sleep at home. According to Otakuma Keizai Shimbun, which wrote up the comic with the author's cooperation, the author felt too unwell to go to hospital unaided, followed the advice, then had worsening headaches and could not drink ordinary water, and rushed to hospital on the third day, where the author received two IV drips. The author called it leaving heatstroke to AI, but also blamed lack of sleep and fluids and said people put too much responsibility on AI. Two days after posting the author had not fully recovered.

AI system as recorded: ChatGPT, which the author asked about heatstroke symptoms (named in the comic by its Japanese nickname, as identified by Otakuma)
What Happened
The comic. On 8 July 2026 a manga artist posted on X: "I got heatstroke." The attached comic page is titled, in translation, "When it seems like heatstroke, relying on AI is dangerous, so go to hospital." One panel shows a phone with ChatGPT's reply: drink OS-1 rehydration solution, keep cool and sleep at home. Another shows the author on a hospital bed with a second IV bag, captioned that the author left heatstroke to AI and needed two drips because one was not enough.
The account. Otakuma Keizai Shimbun wrote up the comic on 11 July with the author's cooperation. It says the author rarely used ChatGPT but felt too unwell to go to hospital unaided, followed the advice while symptoms were mild, then had worsening headaches, could not drink ordinary water, found the rehydration drink of little help, and rushed to hospital on the third day. Otakuma wrote that relying on the AI's advice apparently delayed the hospital visit, and that two days after posting the author had not fully recovered.
Limits. The author also wrote that heatstroke can come on indoors when lack of sleep and fluids combine, and that people place too much responsibility on AI. The full conversation is not shown, so whether ChatGPT mentioned warning signs or when to seek care is unknown. The dates of the illness and the author's location are not stated.
