Chronotype

Sleep is one of the many biological rhythms that humans experience. In particular, the sleep wake cycle is called the circadian rhythm. This rhythm runs on a roughly twenty-four-hour cycle. Sleep consists of roughly a third of it and is controlled by the hypothalamus within the brain. The typical sleep cycle consists of five different stages and can lead to health consequences if not fully rested. A typical night’s sleep cycle consists of two different types of sleep known as NREM (non-Rapid eye movement) and REM (rapid eye movement). These types of sleep make up the five different stages a person is in while sleeping. When a person first begins to drift to sleep, their awake (W) beta waves begin to decrease and alpha waves increase. When the person is finally in N1, the alpha waves have stopped and the larger theta waves become predominant. Once in N1, a person is in a light sleep that is fairly easy to come out of. Stage N2 will come next with the slowing of the heart rate and breathing. Short, increased activity can be found in this stage called sleep spindles. In the following stage in N3, the even larger waves known as delta waves come in to play. This stage is known as deep sleep as the waves are the longest indicating a low level of functioning. Once in N3 sleep for a while, the person will progress back to N2 sleep and then to REM sleep. In REM sleep, the voluntary muscles in the body become paralyzed and the body enters a period to where it is almost as if the…

BEEP! BEEP! BEEP! I look at my alarm, it’s 7:00AM. I fall out of bed, furiously brushing my teeth, throw some clothes on, and run out the door to catch the bus. This was my routine every morning. Waking up at 6:45 AM, eating breakfast, showering, and then rushing down to the same bus stop, hopefully, to make the 7:42 AM bus. I heavily relied on the bus my freshman and sophomore years of high school. My parents were always preoccupied, getting my younger brother and sister ready for school and…

Due to tracing my sleep, I have come to realize why this is occurring. I try to go to bed as early as possible, but with all of…

The Circadian clock which is the 24h day and night cycle is having an effect on the psychological activity of all organisms. These processes involve activities such as the wave pattern of the brain, melatonin, and other biological aspects. Melatonin is a hormone in the brain that helps our body to control the sleep and wake cycles. A small portion of it can be found in some certain food such as meat and fruits. Our internal “clock” in our bodies that controls the sleep and wake cycles can also…
