In the modern world there are many issues that influence people and their way of life. For school children it is very hard to get up early in the morning, to go to school and then to do the homework. There are many factors that influence the school performance and affect the sleep of children. These factors have to be limited or there have to be made changes in the way of life of children. Sleep – is a natural physiological process of staying in a state with a minimum level of brain activity and reduced response to the outside world, inherent in mammals, birds, fish and some other animals, including insects.
Today, there are many problems faced by children, as life becomes more in a rush each day and there are many issues that have to be solved. Modern children have so many different things to do, from playing games to staying online. Majority of school children do not imagine their life without staying online and communicating with their friends. Very often children forget about the fact that the sleep is extremely important and influences the school performance, and, as well, all other activities, according to Lack of Sleep Affects Schoolwork (2005). It also influences health and behavior, and leads to major problems, if the sleep is not taken into consideration. People do not know much about the sleep, and there are different theories considering its use and its importance. All that is known for sure that a person can not live without sleep and that each person has to create balance in his life and devote considerable amount of time to sleep. In addition, the word “dream” is called as a sequence of images (generated in phase so-called. “REM”), a person can remember (see also the dream). Physiologically normal sleep differs from others like states – suspended animation (so-called “Hibernation” in animals), hypnotic sleep, coma, fainting, and lethargy. In children sleep is extremely important and children have to receive enough of it. If children have the lack of sleep, then they are not effective at school and they face major problems in the future. There are different reasons for the lack of sleep, but one of the major are that children spend too much time online, even at night, and then they are not capable of performing good at school, which is extremely important.
Sleep normally occurs cyclically, roughly every 24 hours. This cycle is redefined every day, and the most important factor is the level of illumination. From the natural cycle of light depends on the concentration of the hormone melatonin. Increased melatonin causes an irresistible urge to sleep. In addition to sleep at night in some cultures there is a physiologically due to the short nap – a siesta. This kind of sleep is admitted one of the most effective and useful for people, as it helps them to rest, even sleeping some minutes and those who practice siesta- do their work much better, according to Sleep Disturbances in Children Causes Poor School Performance (2009).
Dream – is a special state of consciousness of people and animals, which includes a series of stages, regularly repeated throughout the night. The appearance of these stages is due to the activity of various brain structures. A healthy human sleep begins with the first stage of slow wave sleep (Non-REM sleep), which lasts for 5-10 minutes. Then comes Stage 2, which lasts about 20 minutes. Another 30-45 minutes to the period 3.4 furlongs. After that, sleep is coming back in the 2nd stage of slow wave sleep, which occurs after the first episode of REM sleep, which has a short duration – about 5 minutes. This entire sequence is called a cycle. The first cycle has duration of 90-100 minutes. Then the cycle repeats, with the fraction of slow wave sleep and gradually increasing the proportion of rapid eye movement (REM sleep), the last episode of which in some cases can exceed 1 hour. On average, with the full healthy sleep there are celebrated five complete cycles. Sequence of changes in stages and their duration can be conveniently represented in the form Hypnogram, which graphically displays the patient’s sleep pattern.
Sleep function. Sleep provides rest of the body. Especially children need to be provided with the full cycle of sleep, to have a good rest and get the energy for the whole day. Sleep facilitates are processing and storage of information. Sleep (especially slow) facilitates the consolidation of learned material, REM sleep implements subconscious model of expected events. Dream – is considered an adaptation of an organism to changes in illumination (day / night). Sleep restores the immune system by activating T-lymphocytes, struggling with colds and viral diseases.
The necessary duration of sleep. Sleep duration is usually 6-8 hours a day, but changes are possible within fairly wide limits (4-10 hours). Sleep disorders its duration, which can vary from several minutes to several days. Duration of sleep in infants, adults and older people is 12-16, 6-8 and 4-6 hours per day, respectively. Sleep duration of less than 5h, or violation of the physiological structures, are considered the risk factors for insomnia.
According to Sleep deprivation may be undermining teen health (2001), sleep deprivation is a very difficult trial. Within days, a person loses clear consciousness, he feels an irresistible urge to sleep, occasionally “fails” in the border state of confusion. This method of psychological pressure was used for interrogations without reason, it is now regarded as a refined torture.
Sleep affects people’s health, work and studies. Children with the sleep disorder can not perform their activities at the proper level and consequently, problems arise, that lead to different challenges and problems at schools and also health problems. Parents have to balance children’s life and ensure that they have proper rest and control their life in a certain way. There should be devoted more time to the healthy sleep, and should be from 4 to 8 hours, but these figures are quite arbitrary. The need for more long-term dream is manifested, for example, when there is a large amount of physical work. About a third of the life we are in a dream, so it was important to preserve its natural rhythms of nature, according to Research Finds Poor Sleep Effects Student’s School Performance (2005).
Almost all parents face with sleep disorders in children. Each kid, as if healthy he is, no matter how well his mother cared for him, goes through similar problems. Despite the facts that sleep disorders in children occur much less frequently than in adults, doctors give them a great value. This is due to the role of “quantity and quality” of sleep for normal mental and physical development of children, according to Lack Of Sleep Affects School Results (2007).
All in all, sleep has a considerable effect on school performance and there are many issues that have to be taken into consideration. The sleep problems do not have to be underestimated and there have to be implemented different ways that will prevent them.
