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 you head straight for the hospital once your water breaks--you should have the baby within 12 hours to prevent infection. it really depends.. a friend of mine had her waters 'leak' when she had 5 weeks to go, that was like 3 weeks ago and still no baby - they didnt actually 'break' though.
