Pregnancy changes how and when you sleep. This is thought to be due to a variety of factors such as hormone changes, discomfort, frequency of urination, restless legs syndrome, muscle cramps, mood changes, sleep apnea and chronic medical conditions.
There are two types of sleep, Rapid Eye Movement Sleep (REM) and Non- Rapid Eye Movement Sleep (NREM). NREM is divided into 3 stages: Stage 1 (S1) is a light drowsy state of sleep that is non refreshing. We normally spend less than 5-10% of our time in this stage of sleep. Stage 2 (S2) is the first true stage of sleep. Occasional large brain waves generated deep within the brain appear during S2. We are in S2 45- 50% of the night. Stage 3 (S3) is also known as deep sleep. It is characterized by large brain waves that come less frequently than during wakefulness and S1 or S2 sleep. We spend 25% of our sleep time in S3.

- Coagulation and flocculation - Before water is filtered chemicals are added to the water. The chemicals bind to particles in the water making it easier to remove the particles for the water. These larger particules are called floc.
- Sedimentation - The floc settles to the bottom of the water collecting tank in what is called sedimentation. The sedimentation is not removed from the tank with the water.
- Filtration - The water above the sedimentation is passed through a variety of different types of filters: sand, gravel and charcoal. This removes or reduces the amount of contaminants.
- Disinfection - Almost all water treatment facilities use chlorine or chloramine to kill parasites, bacteria, viruses and germs. In some areas, municipalities add fluorine to the water. Fluorine is not added to kill organisms. It is added to decrease tooth decay among children
