If you stay up late at the beginning of pregnancy, your body’s resistance is reduced during pregnancy, and your immunity is also reduced. Staying up late often will aggravate the situation of reduced body resistance, which may lead to the appearance of some diseases, the most common of which is the tendency to cause upper respiratory tract infections. The lack of good rest during pregnancy will inevitably affect the decrease in appetite and clinically affect the development of the embryo. Therefore, it is recommended to have a regular life in early pregnancy and not to stay up late to avoid the situation of embryonic development due to frequent late nights. In addition, the diet should also be strengthened in order to facilitate the normal development of the embryo. It is also recommended to take folic acid tablets in the early stages of pregnancy to prevent malformations of the fetal neural tube.
