Why sleep is important for students for health?
Students should get the proper amount of sleep at night to help stay focused, improve concentration, and improve academic performance. Children and adolescents who do not get enough sleep have a higher risk for many health problems, including obesity, type 2 diabetes, poor mental health, and injuries. Importance of Sleep The American Academy of Sleep Medicine has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours. Research suggests that sleep helps learning and memory in two distinct ways. First, a sleep-deprived person cannot focus attention optimally and therefore cannot learn efficiently. Second, sleep itself has a role in the consolidation of memory, which is essential for learning new information. “Sleep affects almost every tissue in our bodies,” says Dr. Michael Twery, a sleep expert at NIH. “It affects growth and stress hormones, our immune system, appetite, breathing, blood pressure and cardiovascular health.” Research shows that lack of sleep increases the risk for obesity, heart disease and infections. Scientists agree that sleep is essential to health, and while stages 1 to 4 and REM sleep are all important, deep sleep is the most essential of all for feeling rested and staying healthy. The average healthy adult gets roughly 1 to 2 hours of deep sleep per 8 hours of nightly sleep. Common causes of chronic insomnia include: Stress. Concerns about work, school, health, finances or family can keep your mind active at night, making it difficult to sleep. Stressful life events or trauma — such as the death or illness of a loved one, divorce, or a job loss — also may lead to insomnia.
Why is sleep important 4 reasons?
Sleep is important because it enables the body to repair and be fit and ready for another day. Getting adequate rest may also help prevent excess weight gain, heart disease, and increased illness duration. While all stages of sleep are necessary for good health, deep sleep offers specific physical and mental benefits. During deep sleep, your body releases growth hormone and works to build and repair muscles, bones, and tissue, and immune system functioning. Sleep deficiency is linked to many chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression. Sleep deficiency is also linked to a higher chance of injury in adults, teens, and children. Insufficient and poor-quality sleep represent high-risk factors for health outcomes such as cardiovascular disease, cognitive impairment, and metabolic dysfunction; poor sleep has also been associated with risk-taking behavior, accidents, increased mortality rates, and diminished quality of life [1,2,3]. Lack of sleep is associated with many negative health effects, including increased risk of heart disease, depression, weight gain, inflammation, and sickness. Though individual needs vary, most research suggests that you should get between 7 and 9 hours of sleep per night for optimal health. Sleep decreases cortisol levels A lack of sleep can cause the body to react as if it’s in distress, releasing more of the stress hormone, cortisol. Cortisol is responsible for your fight or flight reaction to danger, increasing your heart rate in anticipation of a fight.
What are the factors that affect students sleep?
The reasons for student sleep deprivation are many, including a wide range of social, cultural, environmental, and biological factors (e.g., personal interests and problems; involvement with “extracurricular” activities including technology and social media; academic demands; living conditions that interfere with sleep … At a more advanced level, sleep deprivation can over-stimulate parts of the brain and even lead to permanent brain damage, according to a report on sleep deprivation among students published by The Guardian. “This is because of the brain’s ‘neural plasticity’ – which means its ability to adapt to new situations. It may be that she is going to bed too late; is bored in school; has a medical problem, such as allergies, diabetes, or hypoglycemia; or is experiencing side effects of medication. When investigating the reasons, look for a pattern by examining when and where the student falls asleep. Studies show people who are sleep deprived report increases in negative moods (anger, frustration, irritability, sadness) and decreases in positive moods. And sleeplessness is often a symptom of mood disorders, such as depression and anxiety. Research has shown that adequate sleep helps to improve memory and learning, increase attention and creativity, and aid in making decisions. In reality, sleep actually propels your success in several ways, according to modern scientific research. From physical to mental, rest plays many important roles in how you act, think, feel and perform.
How does sleeping benefit your health?
Regulated Blood Sugar The cells then use glucose as energy. Sleeping seven hours or more each night helps ensure blood sugar is regulated in the body. See Full Reference . Adults who get less than seven hours of sleep at night are at increased risk for Type 2 diabetes. Sleep helps to prepare our brain for learning new things. When we are well rested we can pay better attention to new information that we come across in our daily experiences. Sleep will help make new information ‘stick’. During sleep, the brain replays memories from the day, making the neural connections stronger. Not only does it help you maintain your physical and mental health, it also helps in maintaining a decent and healthy lifestyle along with ensuring safety from a number of fatal diseases. It is usually said that the mood in which you wake up is largely dependent on the type of sleep you have been in. The longest recorded time without sleep is approximately 264 hours, or just over 11 consecutive days. Although it’s unclear exactly how long humans can survive without sleep, it isn’t long before the effects of sleep deprivation start to show. After only three or four nights without sleep, you can start to hallucinate.
How students can get better sleep?
Examples include taking a hot bath, reading a book or listening to relaxing music. Your bedtime relaxing routine will help you to separate your sleep time from your daily activities that may cause you excitement, stress and anxiety. stress and anxiety. a poor sleeping environment – such as an uncomfortable bed, or a bedroom that’s too light, noisy, hot or cold. lifestyle factors – such as jet lag, shift work, or drinking alcohol or caffeine before going to bed. mental health conditions – such as depression and schizophrenia. The mental and physical strain of sleep deprivation can dampen the spirits of even the greatest optimist. The effects of poor quality sleep can manifest as mood swings, irritability, anxiety, and depression – leading to plummeting motivation and ability to see the larger picture. The most common causes of excessive sleepiness are sleep deprivation and disorders like sleep apnea and insomnia. Depression and other psychiatric problems, certain medications, and medical conditions affecting the brain and body can cause daytime drowsiness as well.
Why is sleep important articles?
Many studies have shown that getting enough sleep is important to our health. According to the National Heart, Lung, and Blood Institute, people with sleep deficiency have a greater risk of many health complications, including heart disease, kidney disease, high blood pressure, diabetes, stroke, and obesity. Sleep helps maintain cognitive skills, such as attention, learning, and memory, such that poor sleep can make it much more difficult to cope with even relatively minor stressors and can even impact our ability to perceive the world accurately. Scientists identified a gene that causes people to naturally sleep less than six and a half hours each night without any apparent ill effects. The findings reveal a mechanism affecting quality sleep and suggest an avenue to investigate for new sleep treatments. It’s common to miss 24 hours of sleep. It also won’t cause major health problems, but you can expect to feel tired and “off.” According to the Centers for Disease Control and Prevention (CDC) , 24-hour sleep deprivation is the same as having a blood alcohol concentration of 0.10 percent. During sleep, your brain deals with information received during the day. It consolidates memories and clears plaque-forming amyloids and tau proteins associated with Alzheimer’s disease. “There’s a cleanup process that happens in brains when we sleep,” St-Onge said. The most important sleep stage is Stage 3, Non-REM or, Delta (Slow Wave) Sleep, it takes up 25% of our total sleep cycle, and it’s known as the ‘deepest’ period of sleep. It’s in Stage 3 that sleep is at its most restorative, helping our bodies heal themselves and our minds rest.
How many students suffer from lack of sleep?
Research has found that 73 percent of high school students regularly do not get a healthy amount of sleep. Too much sleep on a regular basis can increase the risk of diabetes, heart disease, stroke, and death according to several studies done over the years. Too much is defined as greater than nine hours. The most common cause is not getting enough sleep the night before, or cumulatively during the week. See Full Reference advise that healthy adults need between 7 and 9 hours of sleep per night. Babies, young children, and teens need even more sleep to enable their growth and development. People over 65 should also get 7 to 8 hours per night. “Sleep affects almost every tissue in our bodies,” says Dr. Michael Twery, a sleep expert at NIH. “It affects growth and stress hormones, our immune system, appetite, breathing, blood pressure and cardiovascular health.” Research shows that lack of sleep increases the risk for obesity, heart disease and infections.
