Sleep timing is largely based on hormonal signals from the circadian clock. The sleep cycle can be defined as the oscillation between non-REM (rapid eye movement) and REM sleep, which will both be discussed below. For the purposes of this page, sleep will primarily be discussed as it relates to humans. The ability to react to stimuli is one of the distinguishing factors between the states of sleep and wakefulness. Sleep describes a recurring state in which the body and mind are at rest, reducing muscle activity, interaction with surroundings, and the ability to react to stimuli. When counting, please deduct the time taken to fall asleep, which can be very different for different people. Use the Hours Calculator if you would like to find out the number of hours slept when you know what times you woke up and went to bed. They found that bedtime procrastination was a very real problem, and one that was associated with regular old procrastination as well trouble with self-regulation, defined by the psychologist Steve Stosny as "the ability to act in your long-term best interest, consistent with your deepest values." The Takeawayīedtime procrastination is unique, the researchers write, because while people often procrastinate to put off undesirable tasks, sleep is not generally considered undesirable.Use this calculator to compute what time to wake up or go to bed to get a given number of hours of sleep. Participants were also rated for self-control, conscientiousness, impulsivity, and action control.

They asked participants to rate, on a scale of 1 (almost never) to 5 (almost always) how much the following statements applied to them ("R" items are those that are not typical of bedtime procrastinators): 1. The research team, led by Floor Kroese, surveyed 177 people on Amazon's Mechanical Turk to assess what bedtime procrastination is and who is likely to do it. The Utrecht researchers wanted to explore how procrastination behavior might affect health, and whether procrastinators were also less likely to do things like exercise and eat vegetables (as previous research has shown) because both behaviors are associated with poor self-control. He says people want to go to bed on time, and yet many don't. “It’s a longstanding puzzle in philosophy, since Aristotle: why it is that people fail to do what they know is good for them to do,” Joel Anderson, a researcher in Practical Philosophy who coined the term "bedtime procrastination," told Morais. The study was recently highlighted in an article by Betsy Morais in the New Yorker online. "Bedtime procrastination is defined as failing to go to bed at the intended time, while no external circumstances prevent a person from doing so," a team of researchers from Utrecht University write in a recent issue of the journal Frontiers in Psychology.
