Contractions at night are mainly considered to be related to vagus nerve excitation at night, changes in body position and endocrine changes. Contractions are mainly the phenomenon of uterine contractions in women during pregnancy.
1. Nocturnal vagus nerve excitation: at night, due to nocturnal vagus nerve excitation, it is easy to produce a certain stimulation of the brain, causing the secretion of oxytocin, which will indirectly stimulate the uterus to produce the phenomenon of uterine contractions.
2. Changes in body position: at night, due to changes in the position of the pregnant woman, it is easy to cause the volume of the uterine cavity to shrink, which will affect the activities of the fetus, the fetus is easy to stimulate the uterus, thus inducing contractions.
3. Endocrine changes: endocrine changes are likely to occur at night when you sleep, in a quiet state, the body’s estrogen secretion increases at night when you sleep, when the body’s estrogen level increases, it is easy to cause uterine contractions.
During pregnancy, pay attention to regular prenatal checkups, if frequent and regular contractions occur in late pregnancy, you need to go to the obstetrics and gynecology department as soon as possible to avoid delay.
