External Factors Influence Of Sleep Research

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

Exposure to light and sounds can make sleep difficult to maintain. Light is one of the most important external factors that can affect sleep. It does so both directly, by making it difficult for people to fall asleep, and indirectly, by influencing the timing of our internal clock and thereby affecting our preferred time to sleep. Having a comfortable mattress and pillow can help promote a good night’s sleep. You also sleep better if the temperature in your bedroom is kept on the cool side.

Disturbances in circadian rhythms, the body’s normal sleep and wake cycle, can also impair a person's ability to sleep well. Insomnia can range from mild to severe and occasional to frequent. Doctors often treat insomnia with sedatives to reduce activity in the nervous

A big amount of light plays a decisive role in your sleep.The human body refuses to adjust to the change of time or to adjust to it. Ruining your sleep can also change your mood and the way you do things.Losing sleep can also lack your concentration or memory level. An another effect is that it messes up a farmer's’ morning productivity.

Psychiatric disorders, environmental issues, life depression, chronic stress, and pain or discomfort at night are all factors that can lead to a sleep disorder.

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.

Furthermore, environmental factors can also cause insomnia, as Breslau (1996) found that insomnia was also associated with increased risks of drug and alcohol abuse.

The sleep assessment conducted on the patient had an interesting dynamic in how we think we sleep opposed to how our partner says we sleep. The patient wakes up every morning at 6 a.m. and takes a nap right after lunchtime approximately at 1 p.m. The daily naps, according to the patient, last about forty-five minutes to an hour. When asked about restlessness when waking up the patient with a stern voice and pointed finger says, "When I'm up I'm up and ready to go." The patient also explained that they have no trouble staying asleep; however going to sleep can be challenging depending on if anything troubling is on her mind.

Circadian rhythm is another sleep disorder that has to do with our body functions. In this case, our body clocks are off, due an internal change or external factors like a change in time zones or regions where a midnight sun occurs during a 24-hour period. Bright lights in a room have a similar effect on sleep.

However, Susan Holcomb states that stress is the most common factor leading to insomnia and a variety of factors can affect it worst like being female of the intake of caffeine (2007). Another major statement about the cause of insomnia is simply difficulty falling asleep. These factors causing little sleep one night can add up since postponing an adequate amount of sleep until the end of the week has been shown to cause long term effects. Students who know they will have to stay up late some nights should set aside one or two nights each week when they can afford to sleep more.

Being sleep deprived can also affect driving, can affect performance in school, and can lead to illness (Iarovici, 2014, p. 32). Social activities in college contribute to sleep problems, for example, drug use and heavy alcohol drinking (Iarovici, 2014, p. 32). However, sleep problems are not only caused by unhealthy lifestyles. Sleep problems during college years, a major time of development, can be a sign of mental illness such as depression, anxiety, or bipolar disorder (Iarovici, 2014, p. 40). However, there are students who try have tried everything to fall asleep (e.g., not drink alcohol or caffeinated drinks) and they still experience sleeping problems. Some people have genes that cause them to be more alert during the night than in the morning, and others have delayed sleep syndrome, in which circadian rhythms are abnormal (Iarovici, 2014, p. 42). Delayed sleep syndrome is more common in young adults and interestingly, people obtain enough sleep, but they tend to fall asleep during the early morning than during the night (Iarovici, 2014, p. 42). Even though the individual may be getting eight hours of sleep, such a shift in sleeping time can lead to individuals feeling depressed because they cannot enjoy the activities others enjoy during the day, and can lead to individuals having

In this world there are many problems, but one specific problem is sleep loss. Sleep loss can cause many problems in our world such as health problems, an unproductive habit, and the scientific reasearch of how much sleep people need.

One of the most fascinating natural occurrences known to science is something everyone's body requires them to do, this strange phenomenon is sleep. Sleep is not fully understood by anyone, there are too many variables and unanswered questions to discover what sleep is for and why the human body stresses sleeping so much. Dreams are just as undiscovered as sleep. There are many observations made about dreams and what parts of the brain are utilized during these inter-sleep hallucinations. But like sleep, there is no official reason or meaning behind it. Sleep and dreams, although strange and without apparent purpose, reveal many things about an individual, his or her habits, and potentially innermost subconscious thoughts.

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.

Bright artificial lights at evenings suppress melatonin’s release, a hormone regulating sleep and circadian rhythms. Decrease in melatonin levels weakens internal clocks’ ability to prepare the body for sleep. This not only causes sleeping difficulties but also a groggy and tired feeling after waking up. Rapid-eye movement (REM) during sleep also lessens. This diminishes the brain’s ability to learn and store memories during sleep. Reduced sleep also increases risks of obesity, diabetes, depression and accidents. Greater exposure to natural light could reduce the body’s sensitivity to artificial light.
