気分が悪いって英語でなんて言うの？

Feeling 'rough' is the same as feeling unwell when having head nausea or flu. "I think i'm coming down with something" is a good way of telling someone that you are beginning to feel unwell.

In formal settings, like at work or business settings, you can say, "I'm not feeling well." This is because it's not too graphic nor personal to share. You can use it in written or typed messages to colleagues in the workplace. In casual settings, you can say, "I feel sick," or "I don't feel good." These phrases are more common to use between close associates.

When you are not feeling 100% good you could explain this by saying you don't feel 100%, you feel a bit rough, you feel sick, you are feeling unwell, you are not feeling good, or you are feeling a bit under the weather. These are all terms to explain that you do not feel healthy without going into detail about your symptoms.

Any of these phrases can be used to explain that you aren't feeling like your normal self.

When you want to explain to someone that you are not feeling well, then you may express it in the following ways: -I feel ill. I have (nausea/heartburn) -I don't feel too well. -I'm sick. I think I might have caught a cold.

If someone is 'under the weather' it means that they are not feeling 100% well. It may be just a slight inconvenience such as a cold or stomach ache - or it could be something more serious.
