This obstruction can be caused by a variety of factors, including: -Excess weight: Being overweight or obese can lead to the narrowing of the airways, making it more difficult for air to flow freely during sleep. -Age: As we age, the muscles in our throat can become weaker, leading to an increased likelihood of snoring. -Alcohol consumption: Drinking alcohol before bed can relax the muscles in the throat, causing them to collapse and obstruct the airways. -Sleep position: Sleeping on your back can cause the tongue and soft tissues in the throat to collapse, leading to snoring. -Nasal congestion: Allergies, sinus infections, or a deviated septum can cause nasal congestion, leading to snoring.
