Sleep And Sleep : Sleep Schedule Look Like

This investigation examines is it possible for light pulses to alter the motor skills, and cardiac movements of biological life forms. Is it possible to change how biological lifeforms functions if we were to shine a light on them every hour at night? Knowing how most animals work, and from that of human experience I can say that light is what makes us stay awake; therefore if we have a light shined on us every hour would we lose sleep? These are the type of questions I will be answering throughout my extended essay. I will talk about how our sleep is affected by light, and monitor this so I can then record the data. I will also be discussing why we sleep. Which you may be wondering how this ties into light, however light does damage our skin

Sleep is a complex mysterious phenomenon that we don’t know much about including why we dream and different actions associated with lack of sleep like yawning or illness, but there are many theories as to why these things occur along with facts. Why do we dream or have nightmares? What is the point to these things and how do they contribute to our health? Scientists are doing their best to research these things but sleep and things related to it are very mysterious and many things are still left unsolved. There are also many disorders and illnesses connected to the need for sleep and sleep itself, including sleepwalking, sleep apnea, snoring, yawning, dreaming, nightmares, and other various things.

There are four stages of sleep. In the first stage (10 min. into sleep), your pulse slows down and your muscles begin to relax. Your breathing

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

The neonatal or special care nursery environment is one of variable but constant movement, light and noise. Such an environment is not conducive to the entrainment of good sleep habits. Discuss the impact this environment has on preterm infants in terms of their neuropsychological development and sleep patterns. Consider the longer term implications, and the measures that can be taken to minimise or overcome these.

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 a condition were the body & mind which is typically recurs for several hours every night in which the nervous system is relatively inactive, the eyes closed the postural muscles relax and consciousness practically suspended.

Even before I deal with night shift work I've always had an inconsistent sleep schedule. I usually wake up between 6:30 pm to 1:30 am and sleep between 12:00 pm to 6:00pm. It might be confusing, but regardless how chaotic my sleep schedule is, I love how I'm constantly awake past midnight before the dawn. I don't know what's the term between midnight and dawn, but anyhow, I'm pretty sure you get what I'm saying.

A normal night's sleep is when a person successfully goes through all five stages of sleeping. The first stage is when you are lightly sleeping and muscle activity starts slowing down a little. You then start slowing your breathing and heart rate down, as well as your body temperature. The 3rd stage is what is called deep sleep. Deep sleep is whenever your brain start to generate delta waves. The next stage is number 4. This stage is whenever your body is in a very deep sleep and your brain is producing delta waves. The last stage of sleep is the 5th. While in this stage a person may start having rapid eye movement. This is also the stage wear dreaming occurs. It is always important to get a good and full night's rest. Not sleeping can cause

It all starts off with “Stage one”. Although dreaming is rare during this period a lot happens before sleep really has begun. This is the stage where the body is between wakefulness and sleep. This stage is also sometimes referred to drowsy sleep. Breathing gradually becomes more regular, the heart rate begins to slow, the muscles in the body are still quite active, and the eyes roll around slowly and may open and close from time to time (Mastin). This all happens when, the body is preparing to go through, “Alpha and Theta, and have periods of dreaminess, almost like daydreaming, except we are beginning to fall asleep” (Walcult). Alpha and Theta are wave patterns that can be classified into two types of waves. Alpha waves are slow, and increase in amplitude, both occurring at the same time. As for Theta waves, are even slower in frequency and greater in amplitude than alpha waves. These waves are experienced throughout the day but both waves mix together once the body is at sleep. During this short period of very light, easily interrupted sleep, usually only lasting about less than ten minutes, the sleeper may be aware of sounds and conversations, but feels unwilling, rather than unable, to respond to them. A person awakened during this period will often say they have never slept at all, and feel exhausted. Typically, this stage represents only about 5% of the total sleep time (Mastin). All of

Throughout the night most people do not even notice all the different stages of sleep that they go into without even thinking about it. In an entire night of sleep a person goes through four different stages of sleep. When a person first lies down before their body even reaches the first level of sleep they lay there in a relaxed state slowing all of their natural body activities In the first actual

When we receive proper amounts of sleep, we wake up feeling refreshed and ready for the day’s challenges. Sleep can also affect how we feel and perform the day’s tasks as well as how we look. Sleep was once known as a passive state but is now known to be a highly active process during which the day’s events are processed and energy is restored. The sleep cycle involves two distinct phases that alternate cyclically from light sleep to deep then deeper and deepest sleep throughout the sleep period. There are two main phases of sleep: non-rapid eye movement (NREM) and rapid eye movement (REM) sleep, during which dreaming occurs.

Sleep is a complex cycle generated by the brain that consists of 24 hours of regulated wake and sleep stages. This cycle is called the circadian rhythm which is mostly stable, but can be altered by light and individual differences; the individual differences are classified as an either/or dichotomy: you’re a morning person, or you are a not a morning person (Kalat 2013). In normal individuals, sleep is an automatic process; we can fight against it for a while, but eventually the sleep cycle will restore itself, causing the individual to fall asleep at inappropriate times, like during the middle of a lecture, driving down the highway, or while operating heavy machinery. To understand why the circadian rhythm works so hard to stay regulated requires knowledge about the way sleep works and its adaptive
