Whether a Muslim woman sleeps with a hijab depends entirely on her personal preference, home environment, and privacy context, as Islamic law does not mandate wearing a headscarf while sleeping inside one's private home. In Islam, the hijab is required in the presence of adult males who are not immediate family members, but within the private confines of a home or bedroom where no non-mahram individuals are present, women are completely free to remove it. Many Muslim women choose to sleep without a hijab for comfort and relaxation, while others who live in mixed households with extended family members or non-relatives may choose to wear loose, modest clothing or a head covering depending on their specific living arrangements and personal boundaries.
