Research why sleep is so important to health, learning, and memory formation. Include details and statistics about why you should make it a priority in your daily life.
Sleep is a very important factor in our daily life for staying healthy and for developing the right way. Getting enough hours of sleep can help you protect your mental health and function, physical health, quality of life and safety. When you are awake your state of being depends on how much you have slept the night before. While you are sleeping your body is resting and is also recovering from all the activity that it had that day. For children and teens sleep is even more important because it helps them grow and develop. The damage from sleep deficiency can occur in an instant, or it can harm you over time. The increasing amounts of sleep deficiency can have an impact on the risks of chronic health. A good amount of sleep helps your brain to function correctly. While in sleep the brain is recovering for next day trying to remember the things you learned that day. Scientist have proved that a good amount of sleep helps your learning depending on what you do on daily life, such as driving a car, play the piano, helps remember the movements that you make for your basketball shot, and even remembering the lessons of a science class. It also helps enhance your learning and problem -solving skills. Sleep provides improvement in the decisions you make, the attention you pay in class and it even helps you to be more creative. If you don't get enough sleep , it would have a drastic impacts on all the activities listed above and also is linked with the people with depression, people that suicides, and also the risk-taking behavior. Sleep deficiency in teens can change their mood, and can give problems to them for getting along with other teens, they can feel angry, can act in an impulsive way, can have a lack of motivation, which leads to have lower grades in school. Sleep also plays a very important role in our physical integrity, for example sleep is involved in repairing your heart and blood vessels. Some of the risks of lacking of a good sleep are heart and kidney diseases, diabetes, stroke, high blood pressure, and highly increases the risk of obesity. one study of teenagers showed that with each hour of sleep lost, the odds of becoming obese went up. Sleep helps you maintain a healthy balance of hormones that makes you feel hungry (ghrelin) or full (leptin). When you don't get enough sleep, your level of ghrelin goes up and your level of leptin goes down. This makes you feel hungrier than when you're well-rested. The lack of sleep affects how your body reacts to insulin the hormone that controls the blood glucose or sugar.
Sleep also supports healthy growth and development. Deep sleep helps the body to release the hormone that promotes normal growth in children and teens, this hormone also boosts muscle mass and helps repair cells and tissues in children, teens, and adults. Sleep also plays a role in puberty and fertility. Your immune system relies also in the amount of sleep that a person slept, and the lack of it affects the way in which this system responds to illnesses. For example not having enough sleep will make you have trouble fighting common infections. People who are sleep deficient are less productive at work and school, they take longer to finish the assigned work and have a slower reaction time, also make more mistakes. After several nights of losing sleep, even a loss of just 1 to 2 hours per night, your ability to function suffers as if you haven't slept at all for a day or two. Lack of sleep may also lead to microsleep. Microsleep refers to brief moments of sleep that occur when you're normally awake, and you don't remember parts of your day or your activity. Most people have experienced sallow skin and puffy eyes after a few nights of missed sleep. But it turns out that chronic sleep lacking can lead to lackluster skin, fine lines, and dark circles under the eyes. It's estimated that driver sleepiness is a factor in about 100,000 car accidents each year, resulting in about 1,500 deaths. (National Heart, Lung, and Blood Institute, February 22, 2012) Sleep deficiency or the lack of sleep was a factor in some of the biggest disasters in recent history: the 1979 nuclear accident at Three Mile Island, the massive Exxon Valdez oil spill, the 1986 nuclear meltdown at Chernobyl, and others. But sleep loss is also a big public safety hazard every day on the road. Drowsiness can slow reaction time as much as driving drunk. According to some estimates, 90% of people with insomnia, a sleep disorder characterized by trouble falling and staying asleep, also have another health condition.

Milagro Cannon Science 9 Blog: Importance of Sleep Sleep is a condition of body and mind which typically recurs for several hours every night, in which the nervous system is inactive, the eyes closed, the postural muscles relaxed, and consciousness practically suspended. Getting enough quality sleep at the right time can help protect your mental health, physical health, quality of life, and safety. During sleep, your body is working to support healthy brain function and maintain your physical health. It also can affect how well you think, react, work, learn, and get along with others. Sleep is really important for a good health, a good learning, and also for a memory formation. Sleep is really important for a good health because it is restorative for the brain. Also growth hormone is secreted during slow wave sleep. Heart attacks and strokes are more common during the early morning hours. This fact may be explained by the way sleep interacts with the blood vessels. Sleep can help on the way of learning too. Many studies shows that a healthy sleep produces a significant learning-dependent performance boost. In motor skill learning, an interval of sleep may be critical for the expression of performance gains; without sleep these gains will be delayed. Sleep is needed for consolidating and optimizing memories. Without sleep, you cannot even experience the sense of a “good day”. Sleep helps the brain commit new information to memory through a process called memory consolidation. In studies, people who’d slept after learning a task did better on tests later. Chronic sleep deprivation may cause weight gain by affecting the way our bodies process and store carbohydrates, and by altering levels of hormones that affect our appetite. Sleep loss may result in irritability, impatience, inability to concentrate, and moodiness. Too little sleep can also leave too too tired to do the things you like to do. Sleep disorders have been linked to hypertension, increased stress hormone levels, and irregular heartbeat. Sleep deprivation alters immune function, including the activity of the body’s killer cells. Keeping up with sleep may also help fight with cancer.

Sleeping is a very important part of life. Sleeping is important in for kids and teenagers for their growth. Sleep brings physical and mental health, quality of life, and even safety to both humans in growth process to full grown adults. Everything that you do while you are awake depends on how much and well you slept. From learning or memory to driving and safety is leaned upon your sleep. Mood is variable upon sleep; if you have good sleep it is less probable that you will be moody, impatient, or irritable unlike when you didn’t get enough sleep you show those emotions (Harvard Health Publications). Even though sleep is crucial to being healthy a report from National Sleep Foundation (NSF) has recorded that at least 40 million Americans experience 70 different types of sleeping disorder (American Psychological Association). Sleep is necessary from babies to full-grown adults, and not sleeping affects each differently and the same at the same time. Newborn babies to 12 months old need to have an average 16-18 for newborns and 14 hours after 9 months of sleep per day (Parents). All babies go through phases of sleep such as: drowsiness, REM (rapid eye movement) sleep, light sleep, deep sleep, and very deep sleep; but as humans grow their span of being awake increases (Kids Health). Later for children from 18 months (a year and six months) to three years old should sleep from 12-13 hours. Finally kids from 3-12 years have about the same average of sleeping routine which is 10-13 hours varying on their specific age. Sleeping for a kid of these ages is very important because they have a busy and tiring day; they do activities from running all day to taking care of their pets that can be very tiring (Kids Health). Teenagers differ from kids and adults in many ways, and sleep is one of them. When a human being is going through their teenage years their internal biological click is being changed. This clock changes and tells the teenager that they should go to sleep later and wake up later. A teenager’s life is busy with school, sports, and extracurricular activities making it hard to get the 8 to 10 hours of sleep necessary (Teens Health). At last we have the category of adults. As I mentioned before as humans grow their span of being awake increases, so when humans are fully grown adults they need less hours of sleep than babies and teenagers. Adults usually need between 7 to 9 hours of sleep to function correctly (Help Guide). The lives of full-grown humans are far more complicated and busy than those of average babies and teens meaning they need more energy to be on task during their day. Sleep is not only important for the body to relax and function correctly, but if you don’t sleep well there are many side effects other than drowsiness. Sleep loss is the cause of many accidents, the National Highway Traffic Safety Administrations measure that 100,000 car crashes and 1,500 crash-related deaths in the U.S are caused because of sleep loss. Having the necessary hours of sleep can also prevent diseases such as: heart disease, heart attack, high blood pressure, or diabetes. Many other problems can be caused because a person did not get enough sleep these are just some examples. Sleeping is a very important part of life that no one should avoid, and preventing diseases and other problems can come from sleeping the necessary hours.
Sleep is important not only for ones own physical well-being but also for mental restoration. Lack of sleep can affect one’s mental condition by making it more difficult to cognitively process information. In other words, it is difficult to learn and think at maximum potential if one is not getting enough sleep. Lack of sleep negatively affects: the nervous system (reactions), the cardiovascular system (breathing and heart rate), metabolic functions, immune system (ability to fight off diseases), stroke, emotional disorders, obesity, alcohol and drug abuse (“Importance of Sleep”, page 4). The need of sleep varies between each individual. Some people can function on only 6 hours of sleep. Contrary to popular belief, the need of sleep does not decrease with age. Another myth about sleep is that one can make up sleep by sleeping in the middle of the day. For optimal alertness during the day, one must be asleep at the time where he or she has reached the lowest core body temperature, reduced or completely stopped movement of most voluntary muscles, lowest heart rate, and reduced brain activity. In other word it is not important how much sleep you get. It is more important when you get it.

Every day is divided up into three main activities: eating, sleeping and education or work. You spend one third of your life sleeping. Why does your body need to sleep? What makes your body know when to sleep and when to wake up? The way your body gets tired starts with something called melanopsin ganglion cells (mRGCs). Melanopsin ganglion cells are located in the eye. The eye detects incoming light by three specialized cell types, rods, cones, and melanopsin that reside in the retina. The melanopsin was not discovered until ten years ago by Timothy Brown, Robert Lucas, and colleagues. They found that melanopsin ganglion cells play an important role in visual perception and sleep. The photopigment melanopsin is found in specialized photosensitive ganglion cells of the retina. These ganglion cells are involved in the regulation of circadian rhythms (a daily cycle of activity observed in many living organisms), papillary light reflex, and other non-visual responses to light (Wikipedia). The mRGCs registers the lack of daylight and sends signals to your brain, which sets off the various processes like releasing melatonin that make you feel tired. You may have noticed that every night you start to feel tired around the same time you normally do, this is circadian rhythms or daily cycle of activity observed by many things like your body temperature, heart rate, alertness, mood, vigilance and memory. Circadian rhythms are like an internal clock every human has that tells your body when it is time to sleep and wake up. The circadian rhythms make it so you can keep the same schedule even if you live in a dark room where no light comes in. This is what tests have shown: “Early studies found that humans isolated for several weeks from the 24-hour light/dark cycle still maintained a cycle of alternating rest (sleep) and activity (wake) that approximated 24 hours. The persistence of this so-called sleep/wake cycle, even in the absence of daily changes in the environment, suggests that humans have an internal biological clock that modulates behavior.”(Douglas).
The big question is why do we need to sleep? Sleep is believed to be an anabolic or building process where it restores the body’s energy supplies that have been depleted through the day’s activities. What gets depleted the neural transmitters and your electric energy so when you sleep you can refill it. Sleep has four different stages: 1. Light sleep. 2. Breathing and heart rate goes regular and temperature of the body drops. 3. Deep sleep and recuperation. • Blood pressure drops. • Muscles relax. • Tissue growth and repair occurs. • Energy is restored. • And many other things shut down and allow your body to use minimal energy to recuperate. 4. Eye twitching and dreaming is also in stages 3 and 4, deep sleep also. The reason you cannot remember things when you are tired is because your nerve connections that make our memories are worked and tired like a normal muscle would be after working out. When you sleep your nerve connections get strengthened during sleep, “‘Sleep embeds the things that we have learned and experienced over the course of the day into our short-term memory,’ says Avelino Verceles, MD, assistant professor at the University of Maryland School of Medicine and director of the school’s sleep medicine fellowship” (WebMD). Your neural connectors also help you pay attention and so if you are tired you do not pay attention and you do not remember things as well as if you were rested and well. Sleeping is the third most important biological need after breathing and eating, but without sleep nothing would get done and we would still be back in the rock ages or we would be dead. The next time you thing you have to cram for a test think about how it will affect your body if you stay up late, is it even worth staying up late to review if you will not remember half of everything you studied? Keeping a schedule will help your body have a stable schedule to be able to regenerate and get better.

Sleep helps the mind and body everyday during the night. As you sleep the brain works on supporting the health of the body. Damages from few sleeping can occur over time or very quickly like fainting or a car crash. Few amounts of sleep can cause problems when thinking, socializing, reacting, working, and learning. Sleeping helps the learning process, making decisions, paying attention, and being creative. Many Studies have shown that getting a good sleep (not too long or too short) can help the body work how it should without causing any problems. Sleep deficiency can effect certain parts of the brain causing problems like learning deficiency, not controlling emotions, and lack of memory. This has also been a cause of depression, risk-behavior, and suicide. Sleeping is in charge of healing heart blood vessels. Lack of sleep is responsible for high blood pressure, heart and kidney disease, and stroke. Lack of sleep has also been considered also a cause of obesity. Studies have revealed that every hour taken away from sleep, the risk of obesity increases. Without enough sleep, the mind makes you feel more hungry. Sleep produces hormone that help children's growth, maturity and the immune system. Losing sleep hours can cause microsleep (short sleeping moments when awake). Drowsiness due to lack of sleep while driving can as dangerous as being drunk. Studies show that newborns should sleep 11-18 hours a day; pre-schoolers should sleep 11-12 hours a day; Children should sleep a minimum of 10 hours; a teen should sleep 9-10 hours and an adult 7-8 hours a day.

Sleep is very important for health because during the night, when you are sleeping, your brain is resting, making space for more things to learn and remember the next day. In anything you do, sleep can help you do better. It helps you pay attention. Without sleep, you might have problems controlling emotions. It is also tied in with depression. If you do not sleep, many people will be stressed, later leading to depression.
Sleep is important in learning because in the night, the brain is making new grooves for information to fill, but if you are awake, thinking, then the next day it will be more difficult to concentrate. Without sleep, the memory patterns are messed up and the brain no longer functions the way it should. “The data show that expectancy for a reward enhances offline learning of a skill during sleep”(http://psycnet.apa.org/?&fa=main.doiLanding&doi=10.1037/a0017256)
These days, statistics show that “prolonged wakefulness is widespread”(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2656292/) everyday life is affected by the sleeplessness. Sleep should be a priority or else many things can happen, like fatigue and nervous, manic energy. In extreme cases, hallucinations begin. Sleep deprivation can be fatal, so sleep should be on the high end of your personal priorities.

Sleep loss is the cause of many accidents, the National Highway Traffic Safety Administrations measure that 100,000 car crashes and 1,500 crash-related deaths in the U.S are caused because of sleep loss. Having the necessary hours of sleep can also prevent diseases such as: heart disease, heart attack, high blood pressure, or diabetes. Many other problems can be caused because a person did not get enough sleep these are just some examples. Sleeping is a very important part of life that no one should avoid, and preventing diseases and other problems can come from sleeping the necessary hours.

Sleep is important not only for ones own physical well-being but also for mental restoration. Lack of sleep can affect one’s mental condition by making it more difficult to cognitively process information. In other words, it is difficult to learn and think at maximum potential if one is not getting enough sleep. Lack of sleep negatively affects: the nervous system (reactions), the cardiovascular system (breathing and heart rate), metabolic functions, immune system (ability to fight off diseases), stroke, emotional disorders, obesity, alcohol and drug abuse (“Importance of Sleep”, page 4).
ReplyDeleteThe need of sleep varies between each individual. Some people can function on only 6 hours of sleep. Contrary to popular belief, the need of sleep does not decrease with age. Another myth about sleep is that one can make up sleep by sleeping in the middle of the day. For optimal alertness during the day, one must be asleep at the time where he or she has reached the lowest core body temperature, reduced or completely stopped movement of most voluntary muscles, lowest heart rate, and reduced brain activity. In other word it is not important how much sleep you get. It is more important when you get it.

Sleep Problems in the America
ReplyDeleteBy Caleb
Every day is divided up into three main activities: eating, sleeping and education or work. You spend one third of your life sleeping. Why does your body need to sleep? What makes your body know when to sleep and when to wake up?
The way your body gets tired starts with something called melanopsin ganglion cells (mRGCs). Melanopsin ganglion cells are located in the eye. The eye detects incoming light by three specialized cell types, rods, cones, and melanopsin that reside in the retina. The melanopsin was not discovered until ten years ago by Timothy Brown, Robert Lucas, and colleagues. They found that melanopsin ganglion cells play an important role in visual perception and sleep.
The photopigment melanopsin is found in specialized photosensitive ganglion cells of the retina. These ganglion cells are involved in the regulation of circadian rhythms (a daily cycle of activity observed in many living organisms), papillary light reflex, and other non-visual responses to light (Wikipedia). The mRGCs registers the lack of daylight and sends signals to your brain, which sets off the various processes like releasing melatonin that make you feel tired.
You may have noticed that every night you start to feel tired around the same time you normally do, this is circadian rhythms or daily cycle of activity observed by many things like your body temperature, heart rate, alertness, mood, vigilance and memory. Circadian rhythms are like an internal clock every human has that tells your body when it is time to sleep and wake up. The circadian rhythms make it so you can keep the same schedule even if you live in a dark room where no light comes in. This is what tests have shown:
“Early studies found that humans isolated for several weeks from the 24-hour light/dark cycle still maintained a cycle of alternating rest (sleep) and activity (wake) that approximated 24 hours. The persistence of this so-called sleep/wake cycle, even in the absence of daily changes in the environment, suggests that humans have an internal biological clock that modulates behavior.”(Douglas).
The big question is why do we need to sleep? Sleep is believed to be an anabolic or building process where it restores the body’s energy supplies that have been depleted through the day’s activities. What gets depleted the neural transmitters and your electric energy so when you sleep you can refill it.
ReplyDeleteSleep has four different stages:
1. Light sleep.
2. Breathing and heart rate goes regular and temperature of the body drops.
3. Deep sleep and recuperation.
• Blood pressure drops.
• Muscles relax.
• Tissue growth and repair occurs.
• Energy is restored.
• And many other things shut down and allow your body to use minimal energy to recuperate.
4. Eye twitching and dreaming is also in stages 3 and 4, deep sleep also.
The reason you cannot remember things when you are tired is because your nerve connections that make our memories are worked and tired like a normal muscle would be after working out. When you sleep your nerve connections get strengthened during sleep, “‘Sleep embeds the things that we have learned and experienced over the course of the day into our short-term memory,’ says Avelino Verceles, MD, assistant professor at the University of Maryland School of Medicine and director of the school’s sleep medicine fellowship” (WebMD). Your neural connectors also help you pay attention and so if you are tired you do not pay attention and you do not remember things as well as if you were rested and well.
Sleeping is the third most important biological need after breathing and eating, but without sleep nothing would get done and we would still be back in the rock ages or we would be dead. The next time you thing you have to cram for a test think about how it will affect your body if you stay up late, is it even worth staying up late to review if you will not remember half of everything you studied? Keeping a schedule will help your body have a stable schedule to be able to regenerate and get better.

Sleep helps the mind and body everyday during the night. As you sleep the brain works on supporting the health of the body. Damages from few sleeping can occur over time or very quickly like fainting or a car crash. Few amounts of sleep can cause problems when thinking, socializing, reacting, working, and learning. Sleeping helps the learning process, making decisions, paying attention, and being creative. Many Studies have shown that getting a good sleep (not too long or too short) can help the body work how it should without causing any problems. Sleep deficiency can effect certain parts of the brain causing problems like learning deficiency, not controlling emotions, and lack of memory. This has also been a cause of depression, risk-behavior, and suicide.
ReplyDeleteSleeping is in charge of healing heart blood vessels. Lack of sleep is responsible for high blood pressure, heart and kidney disease, and stroke. Lack of sleep has also been considered also a cause of obesity. Studies have revealed that every hour taken away from sleep, the risk of obesity increases. Without enough sleep, the mind makes you feel more hungry. Sleep produces hormone that help children's growth, maturity and the immune system. Losing sleep hours can cause microsleep (short sleeping moments when awake). Drowsiness due to lack of sleep while driving can as dangerous as being drunk. Studies show that newborns should sleep 11-18 hours a day; pre-schoolers should sleep 11-12 hours a day; Children should sleep a minimum of 10 hours; a teen should sleep 9-10 hours and an adult 7-8 hours a day.

Research why sleep is so important to health, learning, and memory formation. Include details and statistics about why you should make it a priority in your daily life. http://www.nhlbi.nih.gov/health/health-topics/topics/sdd/why.html http://www.sciencemag.org/content/294/5544/1048
ReplyDeleteSleep is very important for health because during the night, when you are sleeping, your brain is resting, making space for more things to learn and remember the next day. In anything you do, sleep can help you do better. It helps you pay attention. Without sleep, you might have problems controlling emotions. It is also tied in with depression. If you do not sleep, many people will be stressed, later leading to depression.
Sleep is important in learning because in the night, the brain is making new grooves for information to fill, but if you are awake, thinking, then the next day it will be more difficult to concentrate. Without sleep, the memory patterns are messed up and the brain no longer functions the way it should. “The data show that expectancy for a reward enhances offline learning of a skill during sleep”(http://psycnet.apa.org/?&fa=main.doiLanding&doi=10.1037/a0017256)
These days, statistics show that “prolonged wakefulness is widespread”(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2656292/) everyday life is affected by the sleeplessness. Sleep should be a priority or else many things can happen, like fatigue and nervous, manic energy. In extreme cases, hallucinations begin. Sleep deprivation can be fatal, so sleep should be on the high end of your personal priorities.
Sleeping is a very important part of life. Sleeping is important in for kids and teenagers for their growth. Sleep brings physical and mental health, quality of life, and even safety of both humans in the growth process to full grown adults. Everything that you do while you are awake depends on how much and well you slept. From learning or memory of driving and safety is leaned upon your sleep. The mood is variable upon sleep; if you have good sleep it is less probable that you will be moody, impatient, or irritable unlike when you didn’t get enough sleep you show those emotions (Harvard Health Publications). Even though sleep is crucial to being healthy a report from the National Sleep Foundation (NSF) has recorded that at least 40 million Americans experience 70 different types of sleeping disorder (American Psychological Association).
ReplyDeleteSleep is necessary for babies to full-grown adults, and not sleeping affects each differently and the same at the same time. Newborn babies to 12 months old need to have an average 16-18 for newborns and 14 hours after 9 months of sleep per day (Parents). All babies go through phases of sleep such as: drowsiness, REM (rapid eye movement) sleep, light sleep, deep sleep, and very deep sleep; but as humans grow their span of being awake increases (Kids Health). Later for children from 18 months (a year and six months) to three years old should sleep from 12-13 hours. Finally kids from 3-12 years have about the same average of sleeping routine which is 10-13 hours varying with their specific age. Sleeping for a kid of these ages is very important because they have a busy and tiring day; they do activities from running all day to taking care of their pets that can be very tiring (Kids Health).
Teenagers differ from kids and adults in many ways, and sleep is one of them. When a human being is going through their teenage years their internal biological clock is being changed. This clock changes and tells the teenager that they should go to sleep later and wake up later. A teenager’s life is busy with school, sports, and extracurricular activities making it hard to get the 8 to 10 hours of sleep necessary (Teens Health).
At least we have the category of adults. As I mentioned before as humans grow their span of being awake increases, so when humans are fully grown adults they need less hours of sleep than babies and teenagers. Adults usually need between 7 to 9 hours of sleep to function correctly (Help Guide). The lives of full-grown humans are far more complicated and busier than those of average babies and teens meaning they need more energy to be on task during their day.
Sleep is not only important for the body to relax and function correctly, but if you don’t sleep well there are many side effects other than drowsiness. Sleep loss is the cause of many accidents, the National Highway Traffic Safety Administrations measure that 100,000 car crashes and 1,500 crash-related deaths in the U.S are caused because of sleep loss. Having the necessary hours of sleep can also prevent diseases such as: heart disease, heart attack, high blood pressure, or diabetes. Many other problems can be caused because a person did not get enough sleep these are just some examples. Sleeping is a very important part of life that no one should avoid, and preventing diseases and other problems can come from sleeping the necessary hours.
