Okay, so let's start slow--you seem to have two different sentences, based on the / at the end. Let's flesh those out. Sentence one: "Doing housework helps kids to take a break from their stressful studies." This is pretty much fine, but the word "to" is unnecessary. It's a tiny change, but it sounds more natural to my ear. "Doing housework helps kids take a break from their stressful studies." You can even omit "their" if you want, as it is implied. "Doing housework help kids take a break from stressful studies." Short and sweet is usually the rule. Sentence two (and I am guessing at your intend here): "Doing housework helps kids take a break and study life." "To" was omitted, but "and" was added, so we're basically at the same spot here, lengthwise. And that's okay; it's all the words you need. If you want both sentences, which I believe is the point you are making, let's try this: "Doing housework helps kids take a break from stressful studies and study life." That's all right, but we've got "studies" and "study." Personally, I just don't care for the repetition. So, we go for an easy fix with a synonym. How about "schoolwork"? Here it is one, compound word, and is basically the same thing as "studies," right? "Doing housework helps kids take a break from stressful schoolwork and study life." And if you really want to get fancy, insert one extra word to show you are offering a similar, but slightly different option for studying. "Doing housework helps kids take a break from stressful schoolwork and instead study life." Now you just have to convince a kid that washing dishes is more fun than grammar, which may not be too hard. Haha.
