How to differentiate meaning of words


I'm having some problems differentiating between meanings of sentences. For
example the sentence

とても元気は男の子です

can mean, very energetic boy or it can mean very healthy kid.

These two are very different in meaning, how can you tell the difference ?




Other than in very specific situations, 元気 is usually used to describe
'energetic' or 'lively. So without context, it would be energetic instead of
healthy. (Though you sort of have to be healthy in order to be energetic
right? )
