Afternoon naps

As I have mentioned earlier, people around here work all the time. Its crazy. Work work work. Though one good thing does happen. At about 1pm, things sorta shut down for a while. What many people do is take afternoon naps. I guess it is to make up for the lack of sleep that is gotten at night, or at least try and pay some of that sleep debt off. Its odd, the mid day slumber. Though I guess when its so hot out, what else are you to do? I guess it also helps them continue in their ways of doing everything at night. Thats when people come out and everything is going on. I've been in a food court in a mall at 10pm at night, and that wasn't weird at all. In fact, the place was half full. People just eat dinner late around here. I would like to know if, medically, it matters if your sleep is continuous or not. I keep on hearing the 8 hours a night thing, but does it have to be 8 straight hours? Though not like people get the 8 hours even with the nap. I know I haven't been. I need to though, between the heat, the new culture, the newness of everything... boy I've been tired....I should take a nap...
