However, being up all night, and sleeping during the day disrupts that cycle. It affects people whose work requires them to sleep at times other than at night.Īs stated earlier, when you sleep nights, your circadian rhythm is in sync. Shift Work Sleep Disorder, or SWSD, is defined by excessive sleepiness while up at night, and insomnia when trying to sleep during the day (isn't this a normal reaction?). But just what is Shift Work Sleep Disorder anyway? Is Shift Work Sleep Disorder real? But it's a bit more complicated than that, because sleeping odd hours also causes your circadian rhythm to get out of sync resulting in a condition known as Shift Work Sleep Disorder. This is your bodys natural sleep aid which is why sleeping when it's dark produces better sleep. When it's dark, and/or you close your eyes, a chemical called Melatonin is released.
This rhythm is regulated internally, but external cues such as light can influence it as well. The SCN regulates your circadian rhythm, which controls your sleep-wake cycle, and works on a roughly 24 hour period. It's called the Suprachiasmatic Nucleus (SCN), and is located in the Hypothalamus.
These are controlled by a master clock that keeps them all in sync. To begin with, there are a number of biological clocks in you that regulate various functions. Even problem solving and learning can be enhanced by sleep in general.īut just how does this thing called sleep happen? How is it regulated? And how does it get out of whack? In fact, fascinating studies are being conducted that show how learning is consolidated during REM sleep, specifically when it's preceded by SWS. There are also physical benefits to sleep beyond just getting rest. We now know, however, that sleep performs a number of necessary functions. We used to believe that sleep was a state of unconsciousness, where nothing really happened. We'll also explore whether Shift Work Sleep Disorder is a real disorder, and answer the question, 'Is sleeping during the day really all that bad?' Why do we need sleep? Twisty, poignant, and redemptive, The Night Shift is a story about the legacy of trauma and how the broken can come out on the other side, and it solidifies Alex Finlay as one of the new leading voices in the world of thrillers.What are the effects of night shift work on sleep? Let’s look at why we need sleep and when to get the best sleep. On a collision course toward the truth, all three lives will forever be changed, and not everyone will make it out alive. In the aftermath, three lives intersect: the survivor of the Blockbuster massacre who’s forced to relive her tragedy the brother of the original suspect, who’s convinced the police have it wrong and the FBI agent, who’s determined to solve both cases. Police quickly identify a suspect who flees and is never seen again.įifteen years later, in the same town, four teenage employees working late at an ice cream store are attacked, and again only one makes it out alive.īoth surviving victims recall the killer speaking only a few final words. But at a Blockbuster Video in Linden, New Jersey, four teenage girls working the night shift are attacked. Y2K is expected to end in chaos: planes falling from the sky, elevators plunging to earth, world markets collapsing.
