Why sleep is important to the brain?
Sleep is important to the brain, because it is believed that when we sleep it restores brain chemicals and provides rest to the body.
It is also believed that when we sleep, the brain organizes and stores the memories from the specific time period that you have stayed awake.
Sleeping also regulates the release of hormones, not only in your brain but to other parts of your body, it distributes your natural hormones throughout your body, hormones that are essential in the development of a human body and mind.
Also, sleep is one of the most healthiest things you can do for your body and your growth.
It also boosts your immune system,
it strengthens
Getting sufficient sleep is a basic human need and is vital for life. According to Maslow’s hierarchy of needs, sleep is a high priority for survival. Having enough sleep is therefore important to restore body and brain functions, preserve energy, maintain general well-being and prevent illnesses.
Rasch, B., & Born, J. (2008). Reactivation and consolidation of memory during sleep. Current Directions in Psychological Science, 17, 188-192. doi: 10.1111/j.14678721.2008.00572.x
...ep. There are events in sleep that are associated with synaptic modification, which is the basis of brain rewiring that enhances cognition. There is evidence that sleep accelerated transcription of cortical genes that are associated with protein synthesis9. These newly generated proteins are known to be required for strengthening of existing synapses and building new synapses. Studies have found increase of factors associated with brain-plasticity and enhanced learning during sleep5. These factors include phosphorylated or activated CREB, a transcriptional factor, as well as Arc, BDNF, and NGFI-A. These evidence help explain how sleep can influence brain rewiring through synaptic modification. This mechanism helps explain how sleep can modify the brain and ultimately enhance learning. This is a strong evidence that supports the synaptic downscaling hypothesis.
There are three theories on the benefits of sleep. The ‘Restorative Theory’ allows the body and brain to repair itself and restore energy. According to the ‘circadian rhythm theory’ sleep has evolved to preserve beings from harm. The ‘consolidation theory’ is that sleep strengthens neural connections that serve as the basis for learning.
Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.
Each night, the average person spends approximately 7-9 hours giving their bodies a restful vacation in the land of dreams. Considering this, we spend 1/3 (or 25 years) of our entire lives engaging in this idle activity. Although these numbers can appear as a waste of time in our every day lives, sleeping and/or napping is the energy that helps fuel our bodies to function correctly. Sleep is a necessary function in our every day routine in order to make our brains function at the most efficient level. As we sleep, the brain helps us to recuperate and regain strength by “restoring and repairing the brain tissue” (Myers, 2010, p 99). Without this reviving process, we would all eventually deteriorate. By impairing the sleep deprived mentally and physically, it can potentially cause serious harm. We must fade our conscious mind, and let our mind relax within subconscious state.
Sleeping and Dreaming Despite the large amount of time we spend asleep, surprisingly little is actually known about sleeping and dreaming. Much has been imagined, however. Over history, sleep has been conceived as the space of the soul, as a state of absence akin to death, as a virtual or alternate reality, and more recently, as a form of (sub)consciousness in which memories are built and erased. The significance attributed to dreams has varied widely as well.
Getting enough sleep can increase our chances of being more mentally/physically healthy and our safety throughout the day. How we feel throughout the day is depending on our sleep. Lack of sleep can lead to impaired judgment and actions, which can be a safety hazard towards yourself and your surroundings. When we sleep, our bodies are working to revitalize the brain to form new pathways to help with memory functions and our physical health such as healing repair heart and blood vessels and hormone balance. It is very important for everyone to maintain a good night’s rest to maintain daytime performance and lower stress. Sleep will reduce the levels of stress, help others gain control on their actions and avoid depression. Contributing to these sleep benefits will change your body and mind
Because sleep is vital to our well-being, we have to make sure to get an enough quality sleep at the right times as it helps to protect our mental and physical health, quality of life and safety.
Sleep is very important for human beings. Sleeping means taking rest for every person and each person spends one-third of his lifetime sleeping. Without sleeping, no one can exist in this world. Sleeping is essential for a person’s health and well-being throughout his life. Getting enough quality sleep at the right times helps all people protect their mental health, physical health and safety. A person who does not get enough sleep might suffer from mental disorders, diseases and even harmful situations. Therefore, it is important for every human being to have enough sleep.
As soon as one lies down for the night the brain goes to work while everything else relaxes. Long-term memory is transferred deeper into the brain to be stored until later use. New information runs through the frontal cortex to the hippocampus. Most of the dependency of the human brain is in the frontal cortex effecting “motor and executive functions, attention span, initial memory, behavior, and perception.” Sleep is necessary to allow the functions listed to be carried out. A brain deprived of sleep begins to shut down and become weak in its main functions. When it comes to bedtime, it is necessary to establish a routine. Going to bed around the same time every night and getting in at least eight hours is crucial to a strongly functioning brain. Schaefer discusses “ get up and go to bed at the same time every day, do not exercise too close to bed, and avoid caffeine,” a routine like this ensures a good night’s sleep. Allowing oneself to sleep each night prevents effects of sleep deprivation. This would result in a strong memory, improved judgment, better mood, and quick reaction

does to our brain. Although scientists have yet to pin-point everything that occurs when we sleep, they have concluded that health problems are linked with lack of sleep. According to the medical journal written by Samantha S. Clinkinbeard, “insufficient sleep not only adversely affects stress management skills but also increases the risk of colds and infections, is implic...
After sleep, we feel relax and we can able to concentrate more because our mind is totally fresh and we can grab things more easily. According to mental health America “People feel more frustrated and depressed when they are lack of sleep, and there are many accidents occurred on road due to this problem”. There are many strategies to get proper sleep, one of them is going to sleep at same time everyday. A person need to sleep at least 6-8 hours a day to keep mind fresh. As we know excess of everything is bad so if we sleep more than we need, then it can lead to many problems like obesity, laziness and heart problems.
People do not take sleep as important as they should and do not get enough sleep that their body requires to function properly. Sleep is very important for a person 's physical health, well being and healthy brain functions. Without enough sleep our bodies can not perform daily function to our full ability. For many people, sometimes there is just not enough time in one day to complete all their tasks, fulfil all responsibilities and get the minimum sleep their body requires. Why do people not get enough sleep? Being a parent, student or just an adult in the working world comes with many responsibilities. People do not get enough sleep for reasons such as stress, discomfort, or medical conditions.
