Sleep is a physical and mental resting state in which a person becomes relatively inactive and unaware of the environment. In essence, sleep is a partial detachment from the world, where most external stimuli are blocked from the senses. Normal sleep is characterized by a general decrease in body temperature, blood pressure, breathing rate, and most other bodily functions. In contrast, the human brain never decreases inactivity. Studies have shown that the brain is as active during sleep as it is when awake. Throughout an eight-hour sleep cycle, a normal adult alternates between two very different states, non-REM and REM (Rapid Eye Movement) sleep. Sleep is characterized by two distinct states, non-REM sleep and REM sleep. Non-REM and …show more content…
Sleep requirements vary from person to person-some people are naturally short or long sleepers. Thomas Edison, Martha Stewart, and Jay Leno have remarked that they sleep less than five hours a night. In contrast, Albert Einstein and Calvin Coolidge claimed they needed ten or more hours per night. Other well-known people such as Ronald Reagan and Winston Churchill took naps throughout the day. Some experts suggest that the best way to determine personal sleep requirements is by waking up without an alarm clock. The amount of time spent sleeping would be the personal requirement. Other experts suggest that an ideal amount of sleep is the amount needed to feel refreshed and well rested in the morning and alert all day. Contrary to popular belief, the amount of sleep a person needs does not decrease with age. The reality is that sleep patterns and circadian rhythms change as one ages. Infants spend 50% of their sleep time in non-REM sleep and 50% in REM sleep; it has been shown that deep sleep coincides with the release of growth hormones, necessary for growing children. Adults spend approximately 20% in REM sleep, while elderly people may spend only 15% in REM sleep. Older adults tend to spend most of their sleep time in Stage 1 of non-REM sleep. Consequently, they have less REM sleep and report frequent awakenings. A major reason why humans sleep is due to circadian rhythms, also known as the biological clock. A cycle that lasts 24 hours is called
Some people can be fully energized off of 7 hours of sleep, while other may need 9 quality hours of sleep. Many other factors such as pregnancy,aging,previous sleep deprivation and sleep quality can also affect how many hours of sleep you need. In order to get the amount of sleep you need, you must make sleeping a priority! If an activity is interfering with your sleeping, then you should put that activity on pause.
Leonardo da Vinci used naps so much that he didn’t need to sleep at night. Every two hours, he would take a fifteen minute nap. Many believe this contributed to his seemingly endless supply of creativity (Griffey 10). Thomas Edison would take one to two naps per day, and once turned a patron away because he was taking a nap (Griffey 73). Bill Clinton was known for taking naps whenever he could (Griffey 52). These famous figures dispel the myth that taking naps means ones lazy. They accomplished so much, yet knew their individual limitations. They gave full effort when frequent occasions required, but they also refused to run too fast. We can learn from their examples, and restore the nap to our everyday routine.
Everyone knows what sleep is but do they know what it really is? Sleep by definition is the process in which humans and other animals periodically rest, with greater or lesser degrees of unconsciousness and decreased responsiveness to the surrounding world. With the mentioning of consciousness, it is known that our brain is still active while we sleep and has its own biological rhythm. This rhythm includes four distinct stages that repeat
The human body has a plethora of rhythms that regulate activity such as behavioral processes, physiological functions, moods, and performance. Sleep is a major action that falls into this category of
Most people joke around about how important sleep is and they say things like: “If I don’t sleep right now I might die!”. But many people don’t know how true that statement can be or how important sleep really is. The amount of sleep you get is important and how much sleep you need varies depending on your age. Even naps can help people that have unusual sleeping schedules. Sleeping and napping give you the energy you need to go through the day, but over sleeping or napping can make you even more tired than you were before. Sleeping and napping is a very important thing you need to do to be healthy, to have enough energy to go through the day, and help you be more focused throughout the day.
Sleep is an altered state of consciousness. Consciousness, modern psychologists believe, is an awareness of our environment and us. Sleep is the tendency to think of rest. When people get tired they want to close their eyes, lie down and sleep. What is the reason we do this? The human body requires long periods of sleep in order to restore and rejuvenate. When the body sleeps it helps to grow muscle, repair tissue, and structure hormones.
The average human spends about 25 years of their life sleeping. That is equal to one-third of a person’s life. So if sleep is vital and common among every single human, what do you know about it? What happens when we sleep (Attention Grabber)? Before the 1950s, scientists believed that the brain would just “shut off” when we would go to sleep. It wasn’t until the discovery of the Rapid Eye Movement (REM) state that scientists really looked into what happens in the brain while we are asleep. Studies have found that we go through a cycle of stages during sleep, and it is important for our health (Orientation to Topic). Today, I am going to inform you about what really happens when we sleep, and some issues that are found among it (Specific Purpose). In order to really understand this worldwide commonality, you need to know some background on sleep, the stages in the cycle, and some common disorders (Central Idea). I have taken a year long psychology course that went into depth on sleep psychology, and I have done extensive research on the topic to better grasp it (Statement of Credibility). I want to inform you on sleep so you can understand what happens when you close your eyes every night, and so you can detect any irregularities in your sleep pattern (Statement of Goodwill). First, I will give a background of why and how we know to sleep, then I will explain the stages in the sleep cycle, and finally I will tell you about some common disorders (Preview).
Sleep is undoubtedly one of the most essential requirements for the human body to function properly. It plays a very important role in ensuring the wellness of the human body both physically as well as mentally. In fact, the importance of sleep is clear from the fact that it helps you in maintaining a good lifestyle throughout our entire lifetime. Not only does it help maintain our physical and mental health; rather 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. This in itself is a big proof of the importance of sleep in our lives. While sleeping, our body finally gets its share of rest and it also gets ample time in rejuvenating from all the wear and tear that it went through during the entire day. Not only this, the body is in its own working condition when we are sleeping as this is the time when it supports the healthy functioning of the brain as well as physical attributes of our body.
What do the effects of sleep deprivation have on people? When a person does not get enough sleep, he or she is depriving his or her body of something that it needs. A delightful sleep is one of the most satisfying human experiences with a role to play in supporting a good mood and cognitive acuity as well as in promoting physiologic balance and resilience (Chittora, Jain and Suhalka). People think because they get an insufficient number of hours of sleep, they will not have an emotional impact by it. Sleep is a required need for peoples’ day to day life to be able to perform and stay healthy emotionally and physically. The effects of sleep deprivation are an issue because it affects mood, performance, and health.
To begin with, sleep is important so you can feel energized. In source 1; “How Much Sleep Is Enough?” it states that when you take a nap, it boosts your performance. Also, in the chart it states the age and the amount of sleep that age group needs to get.
Sleeping is extremely important for all mammals, but humans especially. Without sleep we are unable to function properly and at our fullest abilities. When we sleep we grow, and it is an opportunity for us to dream which has many benefits. Sleep is also a way for us to relieve ourselves of stress.
 Sleep is not uniform activity, but one produced of different brain waves throughout the night.
We all need sleep to survive. We sleep to rest our weary bodies after a physical day of labor. We sleep to recover from a mentally challenged day. We sleep because it is necessary for our survival as human beings. Growing up I have always heard that we all need at least 8 hours of sleep to function properly the following morning. However, it has been researched that if your normal sleep habit falls between 5 to 7 and you wake refreshed and rested the following morning, this is perfectly fine. Normally we spend approximately one-third of our lives sleeping. That’s a lot of sleep, but without sleep there would be no survival. Although this may be true for most, it is but a well wished fantasy for the insomniac. A person who suffers from insomnia may appreciate getting 3 uninterrupted hours of sleep on any given day (admin, 2011). Insomnia is defined as someone who has trouble falling asleep or staying asleep at nights. There are two types of insomnia: Primary and Secondary insomnia and their potential causes.
A typical night’s sleep is much more complicated than just closing your eyes and waking in the morning. As humans, we live our life on a circadian rhythm. This means that changes occur roughly based upon a 24-hour basis. This circadian rhythm plays a major role in when we get tired and decide it’s time to sleep. This rhythm is theorized to have helped us stay safe thousands of years ago. We would fall asleep during the time that their seemed to be threats roaming around in the dark. to Once we finally get to sleep, our brains and bodies are doing much more than laying in complete stillness. There are five distinct stages of sleep that we experience as we sleep. Each is uniquely different and serves a purpose throughout the night. The first stage of sleep is a very light sleep that lasts for 5 to 10 minutes. During this stage of sleep, you may not even realize that you’re sleeping. While in this stage of sleep our brains power down by 50 percent and produce theta waves four to seven times per second. We proceed to stage two after this. During stage two, our brains power down
Sleep is one of the things that most students can say they do not get enough of. It is a time for us to rest and for a few blissful hours hopefully forget about the stress and worries of school and life. Unfortunately, due to too much work or too much studying to do, often enough, we do not get the amount we need each night to be fully rested the next day. But we have learned to cope with the sleep deprivation by drinking coffee in the morning to wake us up. Even though we are awake, how well can we function throughout the day when we have only had less than five hours of sleep? How much does our behavior change without enough sleep?
