ELI5: Why if I sleep with the fan on I wake up with a sore throat?
gpt
I think its because you keep air circulating that it will become dry, as a result when you breathe in it will dry out your throat, making it sore in the mornings, take a glass of water to bed with you for just before you fall asleep and as you wake up, it will make a difference, alternatively turn the fan off and sleep with fewer sheets.
