Why do some people snore and others don't?

What makes a person snore? Should it be a cause for concern?

According to an episode of Pinoy MD, possible causes of snoring include swollen tonsils or adenoids,  obesity, secondhand smoke, and congestion like cold, asthma, or allergies.

Dr. Pearl Angeli Diamante, a neurologist and sleep medicine specialist, said, "May mga variability po 'yan. Ibig sabihin may tao na makitid ang daluyan ng hangin, at may iba pang bagay na nakakadagdag ng pagsikip ng daluyan ng hangin ng isang tao."

"Kapag kabataan po, mas madalas nangyayari po, mas malaki ang tonsils po nila kaya naman po 'yun yung bumabara sa daluyan po ng hangin kapag nakahiga lalo na 'yun po 'yung dahilan kung bakit di makapasok ng maayos 'yung hangin at nagkakaroon po tayo ng hihilik."

People who experience this may need to enter a sleep study or polysomnography.

According to Dr. Pearl, a diagnostic study may cost somewhere between P10,000-P15,000, possibly reaching P20,000.

For a split night, which are two studies in one night, she said that may cost P20,000-P30,000.

To prevent snoring, it's suggested to sleep on your side and elevate your head with more pillows. If you have a cold, decongest by blowing your nose before going to bed.

It can also be helpful to lose some weight. Avoid drinking alcohol and smoking.

If your breathing stops, it's best to consult a doctor since it may be obstructive sleep apnea.

Other symptoms may include being too sleepy or feeling tired even after getting eight hours of sleep.
