風邪をひく

The grammar is super straightforward. You take kaze (cold) and add hiku (to pull). In conversation, you’ll mostly use the past tense: hiita. If you’re talking to a friend, just say kaze hiita. It’s short and sweet. If you’re feeling polite, use hiimashita. Want to sound a bit sad about it? Use hiite shimatta. It adds a touch of "oh no" to your sentence.

Use this when you have typical cold symptoms. Think sneezing, coughing, or a runny nose. It’s perfect for texting a friend to cancel plans. "Sorry, kaze hiita so I can't go." You can also use it at work. It’s the standard way to tell your boss you’re sick. Just remember to use the polite form there! It’s also great for showing concern. You might tell someone, "Don't catch a cold!" during winter.

Don't use this for a broken leg. It’s strictly for respiratory bugs. Also, if you have the actual flu, use infuruenza. It’s a different beast in Japan. People take the flu very seriously. If you just have a headache, say atama ga itai. Kaze implies a whole package of symptoms. Don't use it for chronic illnesses either. It’s for those temporary bugs that pass in a week.

The word kaze (wind) is the key here. Long ago, people thought illness was caused by "evil winds." These winds would blow into your body and make you sick. By saying hiku (to pull), you’re literally saying you pulled that wind in. It’s a fascinating peek into ancient medical beliefs. Even today, Japanese people are very careful about "cold winds." You’ll see many people wearing scarves even in mild weather. They really want to keep that "wind" out!

You’ll often hear kaze-gimi. This means you feel a cold coming on. It’s like saying "cold-ish." Another one is kaze o hikanai de. This means "don't catch a cold." It’s a very common way to say goodbye in winter. It shows you care about the other person's health. You might also hear baka wa kaze o hikanai. This is a funny proverb. It means "fools don't catch colds." The joke is that fools aren't smart enough to realize they’re sick!
