Sleep Homeostasis, Sleep Deprivation, and Slow Wave Activity Vahan Hovannisian Mrs. Lee AP Biology 10A 18 October 2016 Hovannisian 2 In all species of animals that have ever been studied, sleep cycles are regulated homeostatically. This means that longer an animal stays awake, the longer and deeper the next sleeping period will be. Slow wave activity (also known as SWA), or slow wave sleep, is deep-sleep. If an organism is sleep deprived for a long period of time, there will be…

start before 8 AM, with more than 20% of middle schools starting at 7:45 AM or earlier.(Herrington) Due to this early start, most teens only get 6-7 hours of sleep when they really need 8-10 hours to be healthy. How can schools expect teens to thrive in school when they 're not getting nearly enough sleep to function completely properly? Sleep is so important to your health; yet many teens seem to be very much deprived of it. It is CRITICAL to brain development, memory function, and cognitive…

experience, the optimal air temperature for sleep is approximately sixty-five degrees. The body’s circadian rhythm typically relies on light for its cues to lower body core temperature prior to and during sleep; however, the inverse is equally true where cooler temperatures prompt the body that it is time to sleep. According to The National Sleep Foundation, the sleep cycle consists of ninety-minute sub-cycles, which are further broken into two types of sleep, “NREM” and “REM” (Czeisler para.…

Under-eye Bags? It is often joked about how teenagers love to sleep and can never wake up early however, many do not realize that there are legitimate scientific reasons as to why this is. Many may attribute teenagers’ inherent sleepiness to their staying up late doing who knows what or a general laziness, but, although those may apply to some teens, it is actually caused by a change in their biological clocks, or circadian rhythms, delaying sleep by several hours, something that is also made…

effects that caffeine has on wakefulness is known, but the long-term effects, however, are not. To test for the long term effects of caffeine, Burke, et al. performed their study on our natural body clock, which was published in Science Translational Medicine in 2015. It is known that our natural body clock, called the circadian clock, controls when we wake up and when we start to feel sleepy. Multiple factors are known to affect the circadian clock, including light, food consumption,…

An individual in delta brainwave is completely unconscious and does not dream at all. In the theta brainwave, a person experiences extreme relaxation or a light sleep and happens between 3 Hz and 8 Hz. At this wavelength, the mental state of a person is very receptive and as such, theta brainwave is ideal for hypnotherapy and self-hypnosis by the help of recorded suggestions and affirmations. Additionally, the theta…

Dr. William Dement is recognized as one of the worlds leading authorities on the topic of sleep. In the article titled “Rem Madness, Dement has conducted experiments on patients regarding sleep deprivations. Using an EKG machine he was able to monitor patients in REM. However, when Dement gathered his patients for the experiment he made a mistake. First, he told the patients what they may experience during his experiment, as well as, told them about the probable outcomes of his experiment, which…

of being sleep deprived and driving to school and trying to stay awake after a night spent studying or doing homework. That is why high schools in America should adjust the start schedule to improve their students’ health, safety, and academic scores. Having the start time of schools rescheduled to a later time can positively affect students’ health. In a study done by the American Academy of Pediatrics, only 13% of teenagers in high school are able to get the recommended hours of sleep of 8.5…

of sleeping is beneficial versus non-benificial. Lack of sleep often leads to many psychological and physical burdens such as cognitive impairments, emotional stress, high blood pressure, obesity and digestive problems. Although we know lack of sleeping can cause these affects, scientist have been trying to figure the cure to insomnia for years because a brain without sleeping will always lead to neurological damage. The study of sleep deprivation has been going on for more than a few…

"Ambien" We have all heard the saying "A picture is worth a thousand words" but, advertisers use this to sell their products. This saying is an English idiom referring that a complete idea can be conveyed with just a single still image. Conveys a meaning more effectively than a description and the advertisers use this to their advantage. Everybody has at least once bought a product that we thought would be different, whether it be size, smell, color, or texture among other possible things.…
