There is a clear hereditary aspect, and other factors such as obesity, smoking, drinking, aging, pregnancy, certain drugs or just extreme tiredness can all contribute to snoring. Finally, we are more likely to snore if we sleep on our back.
Snoring not only affects the quality of sleep, but also affects your daily life, as well as affects the relationship with your partner. Severe cases may lead to thickening of the intima in the carotid artery, which may lead to stroke, heart failure, heart infarction and so on.
