Is there word which is better than the word Among for joining two sentences

Some research suggested that we should sleep seven hours per night. https://www.helpguide.org/articles/sleep/sleep-needs-get-the-sleep-you-need.htm

I have written some sentences in response to the above topic:

Sentence 1: I usually spend 12 hours at home.
Sentence 2: I sleep 7 hours, spend 1 hour on eating and bathing, and the housework and homework occupy the remaining 4 hours.

But I couldn't think of a better word to join the sentences together. I tried to join the two sentences together using among:

I usually spend 12 hours at home. Among the 12 hours, I sleep 7 hours, spend 1 hours on eating and bathing, and the housework and homework occupy the remaining 4 hours.

Answer

You could use a pronoun without any joining word:

I spend twelve hours at home—seven of them sleeping, one eating and bathing, and the rest on homework and housework.
