The Romans lived their daily lives according to a strict schedule, getting up at daybreak and going to bed early. People did not go out in the evenings for safety reasons. Public baths were an important part of Roman life, where everyone would go to get clean. The Baths of Diocletian were large, open-air public baths with separate areas for men and women, as well as hot and cold pools. By 300 AD, there were over 850 public baths in Rome where people would socialize and exercise in the open air.
