Change Your Pillows.

Allergens in your bedroom and in your pillow may contribute to snoring. When did you last dust the overhead ceiling fan? Replace your pillows?

Dust mites accumulate in pillows and can cause allergic reactions that can lead to snoring. Allowing pets to sleep on the bed causes you to breathe in animal dander, another common irritant.

"If you feel fine during the day but obstructed at night, these things may be contributing to your snoring," Slaughter says.

Put your pillows in the air fluff cycle once every couple weeks and replace them every six months to keep dust mites and allergens to a minimum. And keep pets out of the bedroom.

Beware before spending money on special pillows designed to prevent snoring, Chokroverty says. "They may work if it props up your head, which fixes nasal issues, but can cause neck pain."
