Composed of 低(てい) (low), 体(たい) (body), and 温(おん) (temperature). The full medical term is 低体温症(ていたいおんしょう) with the suffix 症(しょう) (condition/syndrome), but 低体温(ていたいおん) is commonly used on its own.

In everyday conversation, Japanese people sometimes describe themselves as 低体温(ていたいおん)体質(たいしつ) (having a low-body-temperature constitution) — meaning they tend to run cold and feel chilly easily. This is distinct from clinical hypothermia.
