The prisoners in the camps were treated in very poor ways. The living conditions were also very, very poor.
Most of the time the prisoners lived in old barracks made out of either brick or wood. In these barracks, there were hundreds of three-tier wooden bunk beds which caused a lot of overcrowding. Many people even had to live in the lofts and basements of the buildings due to the number of people. The close proximity of everyone 
caused the spread of many contagious diseases and epidemics. In the brick barracks there was no insulation or heating. Since they had to be built very quickly, there was a mushy ground and no sanitary facilities. The wooden barracks were very similar with damp and leaky roofs causing mushy ground and poor conditions. Many rats and vermin were also present in the barracks as well as many water shortages. Again in the wooden barracks there were no sanitary facilities. A normal day began at 4:30 a.m. when roll call was taken. Roll call usually lasted until 7:00 a.m. and it would be drawn out as long as possible since it made prisoners miserable. Another punishment prisoners would have to face is sitting in a squat position for about an hour or so. Then in the evening, there was another roll call. The normal working day was over 10 hours long and the rest of the day was spent taking roll call and lining up for food. Later, the WVHA made a decree that said in a concentration camp, prisoners must work at least 11 hours a day. Some prisoners worked to build the camp by leveling ground, laying roads, and digging ditches. The other prisoners would work in mines, factories, ect.
Feeding Prisoners
Prisoners usually got three meals a day, breakfast, lunch, and dinner. However, these meals were very small and never enough that the prisoners starved to death sometimes. 
The nutritional values of the meals went off of the nutritional values of the Nazis. Each prisoner had a normal calorie intake for the day, prisoners with less demanding jobs got 1,300 calories and prisoners with demanding jobs got 1,700 calories a day. This was never enough for them to live off of with all the work they were doing. Many prisoners started to experience organic deterioration which can lead to “Muzuman” state which is caused by several weeks of starvation and usually results in death. If the prisoners did not starve to death, they were executed. The first people to be executed were shot to death and then they started using poison gas. At least 20,000 Soviets were killed with poison gas. Sometimes, prisoners would be hung in public to scare the rest of the prisoners.
