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.
Usually the doctor, midwife, or nurse will break your water before you become completely dilated, if it hasn't broken by then. This allows them to learn if you have any problems that would impede the baby's safe delivery. Contractions usually become much more intense after your water breaks, and the labor goes faster. Your physician or midwife should evaluate you and your baby as soon as possible after your water breaks. That's because the baby is at risk of developing an infection in the uterus once the protective fluid is gone. Doctors also advise that women not have sex after their water breaks to avoid introducing any bacteria into the uterus. Your practitioner will want you to have your baby within a day or two after your water breaks. If you are close to your due date, your water breaks, and you don't go into labor on your own within a relatively short period of time, you will need to have labor induced. If your labor doesn't begin within a specific time period, your physician may want to bring on (induce) labor. How long your health practitioner is comfortable waiting before inducing will depend on your individual situation.
