Pregnancy fatigue is common during the 9th week of pregnancy. In the first few weeks of pregnancy, pregnant women will feel tired day and night, and 90% of expectant mothers will feel lazy and weak. This is primarily caused by the hormones in the pregnant woman's body. The placenta secretes a lot of hormones necessary for pregnant women, which are transported to various parts of the body, making the body like a power station. But only a quarter of mothers get enough sleep during the first 15 weeks of pregnancy. Some phenomena that accompany pregnancy, such as nausea, vomiting, etc., can also affect the quality of sleep. Maintaining relaxation training before bedtime, lowering the indoor temperature, and not paying too much attention to sleeping posture can help pregnant women ensure a good sleep.
