It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) sneezed, he (peace and blessings be upon him) would cover his blessed face with his hand or his garment and lower his voice. This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

Sayyiduna Khawwat bin Jubayr (may Allah be pleased with him) says: Sleeping in the early part of the day is foolishness, sleeping in the middle of the day (the siesta, qaylulah) is an excellent habit, and sleeping in the last part of the day (after Asr) is stupidity.
