Only afterwhen researchers first described REM in sleeping infants, did scientists begin to carefully study sleep and dreaming.
Knowing that he has a 9: However, although Julian crawls into bed right on schedule, he finds that he is still completely alert and awake, and lies in bed all the way until 3: The next morning, Julian awakes to his alarm at 7: He groggily drags himself out of bed, not feeling the least bit refreshed.
Not a promising start to his school day. Julian is stuck in the middle of a very common and often harmful pattern in his circadian rhythm, a pattern known in the sleep circle as Delayed Sleep Phase Syndrome DSPS.
It's important to note before moving forward that this article and the anecdotes within are targeted towards delayed sleep phases in students and adolescents. Much of the information will also apply to cases during adulthood, but it will not always be as applicable to all chronic or severe cases of DSPS.
Delayed sleep phase syndrome, common in many adolescents and college students, shifts the body clock so it is hard to fall asleep at night.
DSPS is a sleep disorder in which the cycle of sleep and wakefulness in a person's hour day is significantly delayed. As a result, the clock-dependent alerting mechanism in our brains that releases the hormones that give us energy gets activated a lot later at night than we may like it to.
This then translates to a person having trouble falling asleep at a desired time, instead either up and awake for too long or laying in bed with a racing mind. You can essentially think of it as jet lag--the exact same mechanisms are in play--minus the actual airplane flight.
The other side to DSPS is of course the morning, where it's all too often a difficult endeavor to wake up on time for work or school. Naturally, being up very late can make it VERY difficult to wake up within the parameters of the person's daily schedule, i.
Of course, this then turns into into lost sleep if the individual does have to wake up early in the morning, perpetuating a cycle that can have serious consequences for everything from mood to alertness to productivity.
Read more about the effects of sleep deprivation. Although delayed sleep phase syndome can occur in just about anyone, it is extremely common among young adults and college students, largely due to the schedules they maintain. Yup, behavior as simple as having a frequent late-night schedule is enough to shift the circadian rhythm and bring on DSPS.
D has more on this: D's Sleep Book Says In most cases, however, it is more likely that the delayed phase of the rhythm is also maintained by the behavior of the person, together with the tendency of the major clock-dependent period of alerting to occur late in the day rather than early.
Of course, this makes it rather easy for a college student to develop DSPS and somewhat difficult to get rid of. College students are often up until late hours of the night working on papers or studying for tests, and in such a schedule their body clocks adjust to this so they can be alert at these times.
DSPS in young people can typically look something like the scenes above. Low clock-dependent alerting in the afternoon causes them to be tired during parts of the day, but when the alerting mechanism kicks in at night it makes them alert, wired, and ready to have fun at times when most people are asleep.
Staying awake until the early hours of the morning, of course leads to a higher tendency to sleep-in late. This can lead to two outcomes. Depending on his or her schedule the student will either sleep late every day, shifting his or her biological clock and circadian rhythm to this new pattern; or, say if the student has classes early in the mornings during the week and has to get up for them, he or she will begin accumulating large amounts of sleep debt.
This, combined with late night activities over the weekend leads to students sleeping well into the afternoons on Saturday and Sunday, but as a result, it then becomes very difficult to fall asleep at a "reasonable" time when I say reasonable I simply mean at a time that allows the student to wake up fully rested on time for classes the next day on Sunday.
And so the process repeats. Sound like you or someone you know? Tell us about it! Patient has chronic difficulty falling asleep at desired time to meet their daily schedules - work, school, etc.Essay/Term paper: Dreaming and sleeping Essay, term paper, research paper: Psychology.

In REM, eyes move quicly under the eyelid. Dreaming takes place at this stage. Dreams occur more often and they are more real at this stage.
These dreams are story like, intense, and passionate. Sacred Harp Singing In Western Massachusetts (WMSHC) Sacred Harp, or more correctly shape-note singing, is a truly glorious sound, totally unlike anything else in music.
