This article is about the creatures. For the 2015 film, see Minions (film). The Minions are small, yellow, cylindrical creatures, who have one or two eyes. They are the signature characters of the Despicable Me series. They bring much of the comedy in the film, and they are known as the scene-stealer of the movie. Frequently, they speak in an incomprehensible language, called Minionese, occasionally switching to English.
Leaving your fan on will not cause a cold/sore throat. A cold is cause by airbourne viruses. I suppose a fan can circulate the air in your room a lot more than normal. Chances are you picked up the virus before going to bed. Viruses tend to have an incubation period of (if memory serves me right) around 48 - 24 hours before showing any symptoms.
However, many fan models have a switch that allow the blades to spin in the opposite direction. This pulls the air in the room upwards, which pushes the warm air down the sides of the rooms, making your room a little warmer. This can give your heating unit a much-needed respite during the colder months of the year.
