Snoring 101: Sawing wood and You



-What is Snoring?

When we are asleep, the area at the back of the throat sometimes narrows. The same amount of
air passing through this smaller opening can cause the tissues surrounding the opening to vibrate, which in turn causes the sounds of snoring.

What causes Snoring?

Snoring is caused by restrictions in a person's air passages. This narrowing is usually contributed to the muscles in your mouth and throat relaxing during sleep, and obs
tructing the airway.

This can be caused by a variety of things, including:
  • Mouth anatomy. Having a low, thick soft palate or enlarged tonsils or tissues in the back of your throat (adenoids) can narrow your airway. Likewise, if the uvula (triangular piece of tissue hanging from the soft palate) is elongated, airflow can be obstructed and vibration increased. Being overweight also contributes to narrowing of your airway.
  • Alcohol consumption. Snoring can also be brought on by consuming too much alcohol before bedtime. Alcohol relaxes throat muscles and decreases your natural defenses against airway obstruction.
  • Nasal problems. Chronic nasal congestion or a crooked partition between your nostrils (deviated nasal septum).
  • Sleep apnea. Snoring may also be associated with obstructive sleep apnea. In this serious condition, your throat tissues obstruct your airway, preventing you from breathing. Sleep apnea is often characterized by loud snoring followed by periods of silence that can last 10 seconds or more, which usually means the person has stopped breathing. Sometimes, complete obstruction does not occur, but rather, while still snoring, the airway becomes so small that the airflow is inadequate for your needs. Eventually, the lack of oxygen and an increase in carbon dioxide signal you to wake up, forcing your airway open with a loud snort or gasping sound. This pattern may be repeated many times during the night

-How common is Snoring?

Any person can snore. Studies estimate that 45% of men and 30% of women snore on a regular basis. However, people who do not regularly snore will report snoring after a viral illness, after drinking alcohol, or when taking some medications.

-Why is Snoring
a problem?

Snoring sometimes can be the only sign of a more serious problem. People who snore should be evaluated to be certain that other problems such as sleep apnea, sleeping problems, or sleep related breathing problems. Untreated, persistent snoring caused by obstructive sleep apnea may raise your lifetime risk of developing such health problems as high blood pressure, heart failure and stroke. The repeated lack of oxygen can even cause instant death. In children, obstructive sleep apnea may increase the risk of attention-deficit/hyperactivity disorder (ADHD).

-What can you do to prevent Snoring?

There are a wide range of treatments for snoring, ranging from simple home remedies to surgery or medical equipment.

The main categories of non-surgical treatments are:
  • Behavioral changes: losing weight, changing sleeping positions, avoiding alcohol, quitting smoking, and changing medications that may be the cause of snoring.

  • Dental devices: dental devices have been developed that hold the jaw forward, since the tongue is attached in the front to the jaw, the tongue also is held forward when these devices are used

  • Nasal devices and medications: Breath-rite strips, nasal sprays (steroid and decongestant)

  • Nasal CPAP (Continuous positive airway ressure): wearing a pressurized mask over your nose while you sleep, attached to a small pump that forces air through your airway, which keeps it open

















There are also a variety of surgeries that can be done to treat snoring, including laser-assisted uvulopalatoplasty (LAUP). These should be discussed thoroughly with your doctor before proceeding.

Obstructive Sleep Apnea

Obstructive sleep apnea is a serious sleep disorder that is characterized by interruptions in breathing. Obstructive sleep apnea is caused by a blockage of the airway, usually when the soft tissue in the back of the throat closes during sleep. Since obstructive sleep apnea causes the sleeper to stop breathing, the sleeper is awaken by the need to breath. Hundreds of these suffocating and awaking cycles can occur each night.

Obstructive sleep apnea has many serious side effects. Since obstructive sleep apnea decreases oxygen saturation in blood, it can cause:
  • Hypertension
  • Stroke
  • Heart failure, irregular heart beats, and heart attacks
  • Patients with obstructive sleep apnea have enlarged and thickened hearts that pump less effectively


Furthermore, since obstructive sleep apnea awakens the sleeper even for a brief moment, the sleep causes excessive daytime sleepiness, and other symptoms of fatigue.

The symptoms of obstructive sleep apnea includes:
  • Waking up with a very sore and/or dry throat
  • Occasionally waking up with a choking or gasping sensation
  • Sleepiness during the day
  • Morning headaches
  • Forgetfulness, mood changes and a decreased interest in sex
  • Recurrent awakenings or insomnia
  • Snoring
It has been estimated that obstructive sleep apnea causes 50,000 premature and preventable deaths may occur each year. Obstructive sleep apnea causes cardiovascular diseases and fatigue, which can come in the from of dozing off while driving a car or operating dangerous machineries.



In conclusion, obstructive sleep apnea is a serious disease. If you think you or your roommate, parnter, or anyone else has obstructive sleep apnea, find medical help as soon as possible.
