Learn Swedish: Yogan lugnar såväl kroppen som sinnet. - Yoga calms both the body and the mind.

Both translate to "both ... and" in this context, but såväl ... som is more formal and elegant. You will often see it in written Swedish, journalism, or professional contexts, whereas både ... och is standard for everyday conversation. It can also be translated as "as well as".

Why is yoga written in the definite form (yogan) here?

In Swedish, uncountable nouns representing general, abstract concepts or activities often take the definite form when they are the subject of a general statement. English drops the definite article for concepts like yoga, life, or nature, but Swedish keeps it to talk about the concept as a whole.

Does the grammar of the words after såväl and som have to match?

Yes, correlative conjunctions need to connect parallel grammatical structures. Because kroppen (the body) is a definite noun, sinnet (the mind) must also be a definite noun. If you used an adjective or a verb phrase after såväl, you would need to balance it with the same part of speech after som.

What are the different meanings of the word sinnet?

In this sentence, sinnet (from the root word ett sinne) refers to the mind or state of mind. However, it is a versatile word that can also mean one of the physical senses, like sight or hearing, or refer to a person's temper or general disposition.
