Reference for Shabbat 2:6

עַל שָׁלשׁ עֲבֵרוֹת נָשִׁים מֵתוֹת בִּשְׁעַת לֵדָתָן, עַל שֶׁאֵינָן זְהִירוֹת בַּנִּדָּה וּבַחַלָּה וּבְהַדְלָקַת הַנֵּר:

For three transgressions women die in childbirth [in time of danger, where there is a risk to life]: for laxity in (observance of the laws of) niddah, (the separation of) challah, and the kindling of the (Sabbath) lamp. [Because they (the last two) are household needs, and she is generally found at home, they are relegated to her.]
