3. Avoid alcohol and sedatives
They depress your central nervous system, causing your muscles—which include the tissues in your throat—to relax too much. So avoid drinking alcohol at least two hours before bedtime, and exercise caution when taking sedatives.
4. Fight nasal congestion
Congestion due to colds, allergies, or a deviated septum can limit airflow through your nose, forcing you to breathe through your mouth and increasing the likelihood of snoring. Try taking a hot shower before you go to bed to help open up your nasal passages. Using an oral or spray decongestant also can help, but see your doctor before such medications more than three days in a row. (Long-term use of decongestants can have a rebound effect and eventually make your congestion worse.) Your doctor may prescribe you a steroid spray for chronic congestion. Or, if you have a deviated septum, you may need surgery.
5. Remove allergens in your bedroom
Dust mites in pillows can cause allergic reactions that in turn can make you snore. So wash your pillows every other week, and replace them every six months to minimize dust mites and allergens. Dust your ceiling fan, and keep pets out of your bedroom.
