Chronotype

Sleep constitutes a major portion of our daily lives. During each night, the average person cycles through Stages 1, 2, 3, 4, and REM sleep multiple times before waking. However, hours before we succumb to sleep, our bodies are already hard at work producing hormones that encourage sleep. Many biological factors influence the quality of sleep we experience and one of significant importance is the hormone melatonin. Melatonin plays two major roles in the physiology of sleep. Its first role is to…

. The time one makes up typically previews the kind of day one will have. If one wakes up late then it could tear ones day to shreds, however if one wakes up an hour early it could massively improve their day. The time in which one wakes up generally has an affect on ones personality. Everyone knows those people who dread waking up in the morning or those “Don’t talk to me until my third cup of coffee,” type of people. They are usually grouchy and show little signs of life until around…

Daylight Savings Time is bittersweet for me. I love the extra hours of daylight in the evening, but I hate losing precious hours of beauty sleep. During this time change, it gets extremely difficult to wake up early and on time in the morning, let alone fall asleep at a decent time. I have every intention of going to sleep earlier each night, but my mind is still going a million miles an hour and it never ends up happening. I have experimented with quite a few ways to go to bed earlier over the…

it leads to stress and anxiety. Teenagers need to know that sleep is an important part in a young adolescent life. Many teenagers are night owls. On page 87, Jensen states ““The technical terms for ‘larks’ and ‘owls’ are early and late sleep chronotypes.” Jensen’s point is that teenagers that usually have a hard time falling asleep or stay up have active stress. This finding challenges the belief that kids need sleep 7 to 8 hours of sleep to stay healthy and to be able…

Before immersing myself as a student in the world of sleep, I had always believed that I had a great sleeping pattern. In fact, all of my peers found it amusing how much I loved to sleep, to the point where they said I slept all the time. However, the way that I see it is that I am a 20 year old who goes to a tough school academically, plays a 24/7 sport of basketball for the University, works on campus, and finds time to be social. As one should realize, I am a busy man on a rigorous schedule,…

of the argument will be explored, the evidence ultimately supports and proves that the positives of having a later start time in high school outweigh the negatives. This is due to the varying aspects and effects of adolescence on sleep. Personal chronotypes, or personal preferences, are an obvious factor in this as the majority of teenagers prefer the evening to night-time hours…

Prebedtime behaviors have a great influence on the quality and duration of sleep. “Within the hour before bed, frequent video gaming, computer use, listening to Mp3, and use of mobile phones are associated with later self-reported BT on both school and weekend nights.”() The use of technology before bedtime can activate the mind and result in the flooding of thoughts. Also, the light from screens on technology can suppress melatonin resulting in difficulty falling asleep. However, replacing…
