Along with a nap (siesta) in the day, it has been argued that this is the natural pattern of human sleep.[1][2] A case has been made that maintaining such a sleep pattern may be important in regulating stress.[2] Historian A. Segmented sleep as a historical norm[edit] According to Ekirch's argument, typically individuals slept in two distinct phases, bridged by an intervening period of wakefulness of approximately one hour.[6] People also used this time to pray and reflect,[7] and to interpret dreams, which were more vivid at that hour than upon waking in the morning. The human circadian rhythm regulates the human sleep-wake cycle of wakefulness during the day and sleep at night.

You worry, you toss and turn, finally you go back to sleep, but you know something is wrong with you. Is it? Although some people are never really bothered by irregular sleep patterns, others worry that, if they wake up during the night, they will not get enough sleep and will not be able to function well the next day. How people used to sleep Sleep patterns of yore are not really a part of recorded scientific information. Ekrich suggests that, in pre-industrial times, people went to bed when it was dark outside. This was followed by the "second sleep," which lasted another three to five hours. Thomas Jefferson planned his time well, and would read philosophy before going to bed "whereon to ruminate in the intervals of sleep." Sleep after the Industrial Revolution Beginning in the mid-1700s, people began to stay up later and enjoy the night-time. Along with staying up later and going to bed later, people slept fewer hours.
