Refrain from Smoking
When a person smokes, they are taking in a substance that can exacerbate symptoms of snoring and sleep apnea—not only by affecting their lungs and throat but also their sinuses and nasal passages.
Cigarette smoke constricts blood vessels, which means that your heart has to work harder to deliver blood to your body, and all parts of your body are receiving less oxygen than they otherwise would. As a result, your blood pressure increases, and your heart pumps harder. Over time this can cause fatty deposits to build up on your blood vessels and make blood clots more likely to form. All this means that your heart has more work than it should do just because you smoke cigarettes.
This extra strain will tire out your heart, which in turn will put additional pressure on your breathing muscles that are used during sleep. This extra pressure contributes to snoring by making the soft tissue vibrate and producing noise as air passes over it. When smokers stop smoking, they can experience relief from snoring symptoms after several days or even immediately.
