Examples:
“Especially during migration in the spring and fall, bats can get tired. If they are caught in a cold snap, they can go into torpor, like a mini-hibernation, to help survive the cold period when there aren't insects available to eat for energy.” — Tara Hohoff, The Conversation, 28 May 2026

Did you know?
Cheer up, sleepy Jean (or sleepy Gene)—we know what torpor can mean, and we’re happy to share. Torpor can mean a few things, actually. Most commonly it refers to a state of mind and body characterized by inactivity and lack of energy, as on a torrid (no relation) summer day when one has little desire to do much more than lie around daydreaming. While people may be able to shake off torpor that sets in when the heat takes away the will to get things done, it’s a bit harder for animals, for whom the word has a more technical meaning. An animal in torpor is in a state of lowered body temperature and metabolic activity, usually because of extreme heat or cold. The torpor can last a few hours or it can be months before the creature wipes the sleep out of its eyes.  Torpid, the related adjective (both torpid and torpor come from the Latin verb torpēre, meaning “to be sluggish or numb”) also has both technical and nontechnical applications, as in “torpid animals” or “a torpid economy.”
