Pregnancy without exercise and daily bed rest have an impact on the fetus. Appropriate exercise is beneficial to the healthy growth and development of the fetus, but attention should be paid to the situation of threatened abortion. If threatened abortion occurs during pregnancy, such as vaginal bleeding and abdominal pain, daily bed rest and avoiding excessive walking are required to help maintain the pregnancy. If there is no threatened abortion, daily lying down by pregnant women has an impact on the fetus, which is not conducive to metabolism and may affect the absorption of nutrients, failing to provide enough nutrition for the fetus. Moreover, daily bed rest may lead to poor mood, potentially affecting fetal development. Pregnant women should engage in moderate activities on a daily basis, which is conducive to promoting gastrointestinal motility, improving digestion and absorption capacity, better absorbing nutrients from food, improving sleep, enhancing mood, and benefiting the fetus. If a parturient lacks exercise and lies in bed every day, it will affect natural childbirth and may lead to dystocia. During pregnancy, one can choose suitable exercises, such as walking, yoga, and slow walking, which can promote metabolism, enhance resistance, and contribute to the growth and development of the fetus.
