If you wake up tired or feel sluggish all day because of snoring, it's a problem to take seriously.

When you sleep, muscles in your airway relax and the airway narrows. When the airway narrows too much, it disrupts the airflow, making it turbulent. This rough airflow causes the surrounding tissue to vibrate, producing the noise we know as snoring. The source of your snoring depends on where in your airway the narrowing occurs.
When nasal passages are swollen by a cold, allergies or a reaction to smoking, snoring may be temporary. For someone with a deviated septum, the problem is ongoing.

Lots of devices claim to help people stop snoring. Some encourage you to sleep on your side; others are dental appliances that keep your airway open by preventing your tongue from falling back or by moving your jaw forward.

If you snore only when lying on your back, you can sew a tennis ball or golf ball into the back of your pajamas. This makes it uncomfortable to sleep on your back. You can also keep air passages open by using an extra pillow or propping up the head of your bed a few inches to raise your head.
