Chronotypes: Why Some People Are Night People

         When children hit puberty they experience a delay in their biological block which in turns causes a shift in melatonin. Melatonin is the natural hormone in a person’s body that notifies them if it is time to sleep or time to wake up. A distraction in this can cause many behavior health and mental health issues such as substance abuse, depression or sadly suicide. Only about a tenth of the population actually get the right amount of sleep they need. The minimum amount someone should sleep is eight full hours. In the

Commonly known as Delayed Sleep Phase Disorder (DSPD) and other names, is a disorder in which the persons internal body clock is not in sync with the morning-rise evening-sleep pattern of the majority of people. Individuals with this disorder are not able to sleep and wake at the times that are regulated by normal work and school hours. They usually get enough sleep to keep them at a functional level through the day but not enough to be considered “well rested”. Polysomnography and actigraphy are tests commonly ordered for some sleep disorders to determine the illness. The cause of Delayed Sleep Phase can include a variety of reasons; puberty being one of the main causes, but some people are born with the disorder. The short term and long term effects of this illness is unfortunate for a person’s overall health. Overall cures to this disorder have not been found yet. Doctors have suggested sleeping pills to help or other alternatives. The disorder affects the timing of sleep, peak period of alertness, the core body temperature rhythm, hormonal and other daily cycles.

Circadian rhythms occur every 24 hours; an example of a circadian rhythm is the sleep-waking cycle. We are diurnal animals who are active during the daytime and asleep at night, other animals are nocturnal they are active at night but asleep during the day. The circadian rhythm depends on the interaction of physiological and psychological processes to be tuned into the sleep-waking cycle so energy is provided when needed. As diurnal humans we have a fairly stable sleep pattern with the time we go to sleep and the time we wake up, this consistency suggests an internal mechanism controls sleep, endogenous pacemaker. However, this can be overridden by external factors, exogenous zeitgebers.

I generally tend to go to sleep between 11 pm and 12 am, waking up around 8-9 on my own. When I have to be to work early in the morning, I sometimes rely on an alarm but sometimes my body wakes up on its own and usually go to bed around 10 or 11 pm. I wake up a few times throughout the night normally unless I am extremely tired. According to Myers and Dewall, age and experience can alter the circadian rhythm (2016). I have noticed over the last year my sleeping habits have changed quite a bit. I have started to feel tired later at night and go to sleep later as well. I used to go to sleep around 10 pm but now it’s an hour later than before. My house is normally quiet by 10 pm because my family has gone to sleep. Around that time I go to my

The circadian rhythm is very important in analyzing ones sleep pattern like when they are a sleep pattern like when they are a sleep and when they are awake. One’s normal circadian clock is based on light-dark times over 24 hours.()

The biological clock is a cycle that controls the physiological activities of an organism. It tells your body to sleep at night and be awake during the day. If you do not sleep well, then this can affect the biological clock. Therefore, it is important to do things to get your body ready for sleep. Foster says to “make your bedroom a haven for sleep by making your room dark and slightly cool.” Foster also suggests to turn off the lights. Bright lights delay sleep because it increases the level of alertness and excite the brain. Lastly, he says to not drink caffeine too late in the

However, there is actually a lot of science that goes behind it. During adolescence, teens go through a change in their sleep schedule which is why more teens stay up later at night and struggle to get up in the morning. Though it’s easy to say that a quick solution to this problem would be for teens to go to bed earlier. However, it’s proven that by the time you’re around seventeen years old, your body naturally wants to stay up until about 11 pm. Besides that, there is also the factor of a thing called melatonin in a teens body. Melatonin is a hormone secreted by a gland in your brain that helps your brain differentiate night from day. As a teen, the melatonin gets secreted later which causes the increase of energy later in the night and makes it harder to be able to rest.( Kyla Wahlstrom, para

Regimented sleep schedule: By sticking with a regimented or strict sleep schedule, your circadian rhythm should adapt. Those with variable sleep schedules may have a circadian rhythm that isn’t aligned with their sleep schedule, thus resulting in all types of physiological chaos. Decreasing this physiological chaos with a good sleep schedule may also reduce the

McMahon , et al, 2014). Another factor that can play into S.A.D. is melatonin, which helps with sleep and wake cycles. Rosenthal, et al, notes how the pineal gland, the gland that produces melatonin, will react to dark surroundings with drowsiness that can lead people to being lethargic (as cited in Melrose, 2015). When melatonin increases and serotonin decreases, the offset of the proteins can cause circadian rhythms to be disrupted, which is the bodies “24 hour” clock. Researcher Melrose writes that “…circadian rhythms respond to the rhythmic light-dark changes that occur daily and throughout each of the seasons.” (2015). People with S.A.D. disorder normally find that their circadian rhythms are off beat and timed differently with day lengths, for example feeling tired in the middle of the day while being wide awake or feeling wide awake when it would normally be time to sleep.

People he who has circadian rhythm sleep disorders is unable to fall asleep and cannot keep awake at the times required for normal work, school, and social needs. The key feature of circadian rhythm disorders is a continuous or occasional disruption of sleep patterns.

Based on the importance of sleep and on the vast amount of information available on the subject, it is surprising that many schools all over the United States still have an extremely early start time. Throughout adolescence, sleep is considered to be even more important as the amount of sleep needed does not drop significantly from childhood, however, the changes related to puberty show a delayed evening onset of melatonin causing a change in the circadian rhythm—a person’s “biological” clock—preference to evenings (Owens, Belon & Moss, 2010). Because of this change, adolescents tend to present difficulties falling asleep prior 11pm and waking up prior to 8am could be causing issues from mood and attention problems, to even something less discussed

Circadian rhythm is a daily cycle of activity that is performed. For example, going to the gym, school, and then work, is a daily cycle, whereas sitting on the couch all day and occasionally driving to the store and back is not. It is doing something with your body, but not over doing it. Stress reduction techniques such as yoga and meditation helps to release energy. And treating insomnia in its early stages helps prevent psychiatric disorders such as depression. The longer you wait to try to cure insomnia the longer and harder it is going to be.

Aside from noticing night and day and clocks our body has its own system to tell us when to sleep and when to wake, our circadian rhythm. The human body naturally runs on a twenty five hour clock, so living on a twenty four hour schedule is often hard on the body because it loses an hour each day. On top of this natural loss most people do not get the right amount of sleep each night which can cause a whole host of problems. This is part of

Many individuals, especially adolescents, do not function well early in the morning. “…many teenagers are going to school with their brains essentially in sleep mode” (Kaufman, 2001). This makes it difficult to retain information and in return use the information they have learned later on according to Robert Gerson, a physician and parent (Heinen, 1996). There is a reasonable explanation for why adolescents need the sleep they need at the times in which they need it, or do it for that matter. “Their circadian rhythms, determined by release of the hormone melatonin and other factors, were telling them to stay up later (even if their homework was finished and the day’s chores complete) and to get up later. On basic biological level, many had no more control over that circadian switch than they did over growing facial hair or breasts” (Kaufman, 2001).

The term ‘Shift work’ is usually referred to uniformly divided allocations of the day in which individuals participate alternatively to provide twenty four hour coverage. A shift in sleep schedule conflicts with the body’s natural clock also known as the circadian rhythm into interpreting the time as ‘inappropriate’ and disrupts the homeostatic regulation cycle resulting in poor health outcomes. Fortunately, it is deemed possible to counter unfavourable effects of alternating insomnia and sleepiness through certain practices.
