Light's Effect. Light is one of the most important external factors that can affect sleep. It does so both directly, by making it difficult for people to fall asleep, and indirectly, by influencing the timing of our internal clock and thereby affecting our preferred time to sleep.
The forewaters are released when the amnion ruptures. This is commonly known as the time when a woman's water breaks. When this occurs during labour at term, it is known as spontaneous rupture of membranes. If the rupture precedes labour at term, however, it is referred to as premature rupture of membranes.
About 15 percent of women will start the labor process with their water breaking. This is the amniotic sac leaking fluid. When this occurs, you may notice either a large gush of fluid or a small trickle of fluid. Sometimes, the only thing a woman notices is that her panties are wet.
