Topic : Adverse effects to the body caused by less sleep.

The topic that I choose starts from the habit that is considered normal but not realized the impact is very bad for the health of the body, yes the impact of sleep deprivation, very dangerous can cause weak immune system, according to the definition of sleep experts are as follows, according to Oxford English Dictionary " "According to Potter & Perry (2005), Sleep is a physiological process, which, according to Potter & Perry (2005), is a physiological process which cycles alternately with longer periods of waking. So sleep is a state of unconsciousness but can still be wake up and sleep is a break for all organs of the body. While the definition of "less" according KBBI is the state of something that has not fulfilled as a portion. So lack of sleep can be interpreted as a state of the body that does not get enough rest. If we know that sleep deprivation is bad for health, we will think why sleep deprivation is bad for the body, what illness is caused by lack of sleep, and whether excessive sleep also causes bad thinking for the body.

     Less sleep can cause a person's body to experience a bad condition for the health, brain, or psychological aspects. According to Experts from Harvard Medical School "when a person sleeps less than 6-7 hours every night, the body becomes weak, difficult concentration, body immunity will decrease and increase the risk of contracting the disease, those who sleep less than five hours, have a risk more likely to die at any age of 15% ". So sleep is very important for the health of the human body, if we want to aged elderly then sleep early, and try quantity of sleep time not less than 7-8 hours one day.

     Another argument explaining the effect of sleep deprivation on the brain is the increased performance of the amygdala, the amygdala is part of the brain associated with the emotional aspect, it can also affect the performance of the hippocampus, the part of the brain that serves as a temporary storage of new memories. As a result, people who sleep less likely to have difficulties when having to remember new information. Quoted from The Independent, (27/6). Also according to researchers from Western University, Ontario, Canada, has also conducted research on the impact of sleep deprivation on the brain. '' There is reduced activity on the front and pariental lobes. These areas are very important in terms of decision making, problem solving, and memory, '' harmful effects on brain power are also caused from lack of sleep in my opinion jiga continuous our body lack of sleep then our brain will experience a very unusual forget which is called amnesias.

     

     This discussion is going to explain what the illness suffered by people who sleep less, not only one disease that will come to the body but very much and dangerous from the disease is relatively mild to severe disease, such as the incidence of acne to cancer. Some experts describe the types of diseases that will arise from lack of sleep is obesity, ugly facial skin, osteoporosis, heart disease.

   Obesity is a disease that is often experienced by a person due to overeating, but the factor of lack of sleep is also very influential on obesity. A team from the University of California said they used magnetic resonance imaging (MRI) imaging to see changes in brain activity of sleep deprived people. "These findings provide an explanation of brain mechanisms, which lead to persistence or increased obesity if people are deprived of sleep," scientists wrote in Nature Communications magazine. For the study, experts twice scanned twenty-three people who became guinea pigs. First of all after they slept soundly overnight, and then, after not sleeping overnight. The next day their brain activity is measured when they choose food and portion sizes from 80 food items. Clearly sleep deprivation is a frightening specter assuming obesity or overweight and long-term effects of obesity can cause people to die quickly.

      When sleeping, the cells in the body will regenerate; no exception to the existing cells on the skin of the face. So you can imagine if you lack of sleep, the skin cells will not regenerate optimally. Impact, the skin will look more dull. In addition, lack of sleep can also encourage the body to produce excess hormone cortisol. This is what then makes the skin lose its natural elasticity and smoothness. a natural study conducted in Sweden, compares photos of groups of people who have enough sleep - sleep at least 7 hours a night - with groups of people who sleep only 3-5 hours a night. From the photos taken, groups of people who sleep with enough time is more fresh, healthy, and not sluggish. Some researchers say that sleep deprivation can change the appearance of your face, making the face look older. In some studies mentioned that someone who does not have enough time to sleep at night will look 10 years older than the original age. In the study mentioned that people who sleep less potentially have more facial wrinkles than people who sleep with enough. Under normal circumstances, the body will form collagen - a substance to maintain healthy and skin rejuvenation - when a person is asleep.

 

     The study, published in the journal Experimental Biology and Medicine, shows that mice lacking hours of sleep have decreased bone mineral density that may indicate osteoporosis. The rats' bone marrow is also reported to contain less fat than mice fed enough sleep while doubling the number of megakaryocytes or spinal cells in charge of producing platelets (a component of blood that plays a role in blood clotting or often called platelets). From the experiments of the above scientists we know that lack of sleep causes osteoporosis which is very dangerous for human bone health as well. "These findings indicate that chronic sleep deprivation can affect bone metabolism and bone marrow composition that can have implications for the development, aging, healing and repair of bone and differentiation of blood cells," said the researcher as quoted by huffingtonpost, Thursday (27/09/2012) . "If such a condition also occurs in humans then this study can provide a remarkable understanding to us about the impact of lack of sleep hours on the emergence of symptoms of osteoporosis and the inability of the body to repair bone damage with age," commented journal editor Experimental Biology and Medicine, Dr. Steven R. Goodman.

   

      The next is a disease that often kills people all of a sudden ie heart disease. It is very likely that people who sleep less than five hours a week will experience a heart attack, because the heart will feel tense if not get enough sleep because sleep is the time the heart rate decreases and when the wake up recovered. According to a short sleep study it produces a higher heart rate during the day. In the daytime group, they were seen to have higher levels of norepinephrine and the variability of the pulse at night, when they were awake. "When pulse variability diminishes, this is a marker for increased cardiovascular risk," said lead study author Dr. Daniela Grimaldi, an assistant professor of research at Northwestern University Feinberg School of Medicine. In the study also seen, when they enter the phase of deep sleep, blood pressure drops, heart rate down, really allows the body to recover. But in both groups of which sleep is limited, the heart rate actually increases, especially for groups who sleep during the day.

     If we have been talking about sleep deprivation, is it good sleep? It turns out that excess sleep is also bad for health, who said? "Sleep is one of the things the body needs in order to maintain health and fitness. Do not lose sleep or even late to rest. Because if you sleep over 12 at night, there are many health risks that threaten. '' Reported from Medical Daily. Simply sleep 6-8 hours in one day, because the ideal count like that, do not sleep too often less than five hours and do not also sleep more than ten hours in one day.

     

     So after we discuss about our sleep as human beings who think should take lessons from the material that our body needs to sleep enough to stay healthy and all the organs can function properly. The danger of lack of sleep is always ready to come if we forget to rest. Ideal sleep in one day is 7-8 hours. "To get that healthy 8-hour sleep, which is the number of most people sleeping, you need to be in bed for 8.5 hours," Dr. Daniel Gartenberg of Penn State University, but should not be remembered over sleep let alone up to twelve hours in a day anyway the impact is bad for the body.
