What does the 何も mean in the bolded positive sentence?


While translating the bolded sentence in the following paragraph, I find
myself unable to translate the 何も, as my genki textbook, the [online
dictionary I am using](https://jisho.org/search/%E4%BD%95%E3%82%82), and the
online textbook I am using all say that 何も is used in negative sentences, or
only give translations for it's use in negative sentences only.

> 体力も神経も使い果たし、疲{つか｝れ果てて泥｛どろ｝のように眠｛ねむ｝る毎日が続く。
> 余計なことを考える暇｛ひま｝もなければ、夢を見ることもない。やがて、そ んな生活に慣れはじめると、今度は物事をじっくりと考えることが苦痛になってきた。そ
> **の時々の課題をクリアすることに、全力で取り組んでいる間は、何も思い悩｛なや｝んだりせずにすむ。**

I'm ninety percent certain the bolded sentence isn't being negated, so how do
I go about translating a 何も in a positive sentence?




You're correct that 何も is a [negative polarity
item](https://japanese.stackexchange.com/q/74377/5010) that means "(not) at
all". But you seem to have missed せず is a **negative** verb that roughly means
しないで.
