During pregnancy, it is not recommended to lie down and sleep every day, and to be properly active. If you lie down and do not move every day, it will easily lead to excessive weight gain, and it will affect the coagulation function, and the risk of gestational hypertension, diabetes and thrombophilia in pregnant women will increase significantly. Pregnant women can move normally during pregnancy, as long as they avoid heavy physical labor, and the usual activity time should not be too long. However, for those pregnant women who obviously have preterm miscarriage and need to keep the baby, it is better to pay proper attention to rest.
