Mothers-to-be, better do your best to get enough sleep, as according to Science Daily, poor quantity and quality of rest may cause immune system problems birth complications.

In a study initially published in Psychosomatic Medicine, researchers from the University of Pittsburgh examined the sleeping patterns and cytokine levels of 170 depressed and non-depressed women who were on their 20th week of pregnancy.

The results revealed that women with depression and poor sleeping habits were more likely to experience disruptions in the immune system and adverse birth-related issues. Researchers trace the cause back to an overabundance of cytokines, which they believe may destroy healthy cells and tissue in pregnant women, leaving them vulnerable to diseases.

It is recommended then for adults, especially expectant women, to get at least seven or eight hours of sleep at night. Start following a regular sleeping schedule, and remove stressors from your bedroom to help you get all the Zzz's that you need.
