In English, you can ask "Are you feeling well?" or "How are you feeling?" to ask if someone is in good health. These phrases are commonly used in English-speaking countries to inquire about someone's well-being. Here are some example sentences:

"Are you feeling well today?"

"I hope you're feeling better now."

"How are you feeling after your surgery?"

The English phrase "Are you feeling well?" comes from the idea of "feeling good" or "feeling healthy," which are common ways to describe good physical health in English. "Feeling" is a verb that means to have a particular physical or emotional state, and "well" is an adjective that means good or healthy. So, when you ask someone "Are you feeling well?" you are asking them if they are currently experiencing good health or wellness.
