What Are Health Idioms?
Health idioms are expressions related to the body, medicine, sickness, fitness, or general wellbeing. However, their meanings are usually figurative rather than literal.
For example:
- “Under the weather” does not mean standing below clouds. It means feeling slightly sick or unwell.
Idioms help make English more expressive and conversational. They are especially common in spoken English.
