What is Sleep Deprivation?
A sleep disorder characterized by having too little sleep, can be chronic or acute. Long – term sleep deprivation (lasts four days or longer) is quite uncomfortable. Effects:
-Health ; in form of physical & mental impairment, impairs our ability to think, handle stress, maintain a healthy immune system and moderate emotions. •Depression
•Heart Disease
•Hypertension
•Irritability
•Slower reaction times
•Slurred speech
•Tremors
•Weight Change (Fatigue)
Sleep deprivation can be a fatal at times to and can cause death

Why we Sleep?
One main function of sleep is to provide a time-out period ; body can eliminate waste products from muscles and repair cells, strengthen immune system, recover physical abilities lost during day.
Without sleep our bodies react abnormally.

Rapid Eye Movement (REM)
What is REM? Sleep periods characterized by quick eye movements, loss of muscle tone, and dreaming. The REM periods last from a few minutes to as long as an hour, averaging about 20 mins length.:
Briefin
History
•Breakthrough occurred in the laboratory; by Nathaniel Kleitman.
•He had given one of his grad students, Eugene Aserinsky, a task of finding out whether the slow, rolling eye movements that characterize the onset of sleep continue throughout the night.
•They did rapidly
•William Dement were then able to correlate the REM of sleepers with changes in brain-wave patterns.
•When you first climb into bed, close your eyes and relax, your brain bursts of alpha waves.
•Gradually, these waves slow down further, and you drift into the land of nod, passing through 4 stages, each one deeper then the other. Sources

    Stage #4: brain produces Delta waves stage three and four are called deep sleep cycle. It is important to go through adequate sleep and get the sleep cycle run its course correctly. Our body repairs itself during sleep. Our body has an ingenious way of restoring our body as we sleep; during the day, there is a buildup of different chemicals including adenosine. All of these chemicals are what is thought to make us want to sleep. Scientists have discovered an immunity system in the brain that is called the lymphatic system. The glymphatic system is the main system that clears the waste product that build up in your brain.…

    Any of us if not more than some have experienced some difficulty sleeping. This can happen because of a number of things: We worry about some sort of troubling thing to come or one that has passed, or there is the all too famous insomnia, which gets the best of us from time to time. There are many times in my life that I have had trouble sleeping, whether it was from one of my three children being sick, my husband being sick, me being sick, or my mind just running from here to there which happens quite frequently.…

    When human beings are awake, the electrical activity in their brain usually takes the form of fast, erratic brain waves. These waves are known as beta waves. During stage 1 of sleep, the brains electrical activity begins to change, with the brain waves becoming more slow and regular. This demonstrates that the persons mind is beginning to relax, and these waves are known as alpha waves. The presence of alpha waves in the brain can usually be used to indicate that the onset of sleep has occurred, and that the person is no longer awake. As well as a change in electrical activity, the persons core body temperature will also drop and their heart-beat slow down.…

    Sleep deprivation is a factor that has also contributed to the high death total every year. While many don’t know it, sleep isn’t just mental, sleep is a factor that is also connected to our immune system. In the book Sleep Thieves, our immune system is proven to be more active while we are asleep and can be disrupted of its normal response pattern with loss of sleep (Coren 171). Also, an experiment conducted in Finland had about 10,778 adult subjects where they were followed for six years, being monitored for their health and sleep times. By the end of these six years, the scientist were able to found out that the poorer sleepers from the group was two and a half times more likely to die during that testing period (Coren 173). This is very significant due to the fact that when we are sick, we are asleep through most of the sickness because it allowed the immune system to become increasingly more active. With less sleep, it puts us at risk for disease or sickness because by losing hours of sleep would result in a decreased immunity to illnesses. In addition, a Doctor named Damien Leger was apart of the US national commision of sleep disorders. He created a report full of findings in 1988 where he obtained information of resulting incidents from sleep deprivation. For example, in Dr. Leger’s findings, there were 24,318 deaths and 2,474,430 disabilities that were caused by sleep deprivation (238). This is…

    Sleep Deprivation can lead to fatigue, learning and concentration difficulties and workplace accidents. Medications, illness, stress related to work or home and just personal choice (i.e. going out the night before work) can all be causes of sleep deprivation. Emotional issues such as anxiety and depression can often lead to sleep deprivation or in worse cases, insomnia. Studies suggest that sleep loss may have an effect on the cardiovascular, endocrine, immune, and nervous systems.…

    Sleeping sickness is infection with germs carried by certain flies. These germs are Trypanosoma brucei rhodesiense and Trypanosomoa brucei gambiense. The more severe form of the illness is caused by T. rhodesiense. This results in swelling of the brain. Tsetse flies carry the infection. When an infected fly bites you, the infection spreads through your blood. And some of the risk factors include living in parts of Africa where the disease is found and being bitten by tsetse flies. The disease is very rare in the United States, and is only found in travelers who have visited or lived in Africa. Symptoms are being anxiety, drowsiness during the day, fever, weakness, sweating…After knowing all this about the disease (sleeping sickness) is when we will understand the impact of genomic Education. How we can use this genomic knowledge towards development of new tools for diagnosis, treatment and prevention of sleeping sickness.…

    Machine Design II Prof. K.Gopinath & Prof. M.M.Mayuram FATIGUE CONSIDERATION IN DESIGN OBJECTIVES AND SCOPE In this module we will be discussing on design aspects related to fatigue failure, an important mode of failure in engineering components. Fatigue failure results mainly due to variable loading or more precisely due to cyclic variations in the applied loading or induced stresses So starting from the basic concepts of variable (non-static) loading, we will be discussing in detail how it leads to fatigue failure in components, what factors influence them, how to account them and finally how to design parts or components to resist failure by fatigue WHAT IS FATIGUE? Fatigue is a phenomenon associated with variable loading or more precisely to cyclic stressing or straining of a material. Just as we human beings get fatigue when a specific task is repeatedly performed, in a similar manner metallic components subjected to variable loading get fatigue, which leads to their premature failure under specific conditions.…
