Pregnant women with severe nasal congestion cannot sleep, this condition is usually at the end of pregnancy, because the blood volume of pregnant women expands and the pressure of blood vessels increases, resulting in the mucous membrane of the nasal cavity edema and turbinate hypertrophy, causing nasal congestion. If the symptoms are not serious, you can try to lie on your side, and the upper nostril will remain ventilated; if the congestion is more serious and cannot be solved by simple sleeping position, you can massage the Yingxiang points on both sides of the nose, which has a certain effect of opening the nose. If the conservative treatment is not effective and the condition is very serious, you can try to use nasal application of vasoconstrictive drugs, such as Daphnin spray nose, but these drugs are recommended to be used for no more than a week because of certain side effects.
