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.
It's not always easy to know. If your water breaks, it could be a gush or a slow trickle of amniotic (AM-nee-OT-ihk) fluid. Rupture of membranes is the medical term for your water breaking. Let your doctor know the time your water breaks and any color or odor. Also, call your doctor if you think your water broke, but are not sure.
