A news report from Live Science examines how and why pregnancy affects sleep.

Similar to the advice that a pregnant woman should be “eating for two,” health professionals should also be emphasizing the importance of “sleeping for two” during prenatal visits, Lee told LiveĀ Science.

As their body changes and pregnancy discomforts make it more difficult to fall and stay asleep, mothers-to-be should spend at least eight hours in bed each night so they can get at least seven hours of sleep, Lee recommended.
