The first thing that I thought sleep was very important for most people, especially the students. In the article “Sleep patterns of college students at a public university,” stated “many students have sleep problems that may interfere with daily performance, such as driving and academics.” (Sleep 1) I was a student, I knew not enough sleep would make me felt pain. When we went to school, we need much energy to listen to the teacher. Most of the time, we need to do a lot homework and review for the exam. In the other day, our eyes would fall down, ears would close, brains would mess. Not enough sleep gave us a lot problem to make us be stress. Sometime we would drink something that has caffeine or melatonin to make them has more energy. “Caffeine or melatonin effects on sleep and sleepiness after rapid eastward transmeridian travel,” stated “caffeine or melatonin could degrade the sleepiness.” (Caffeine 2) This was good for us could use the caffeine or melatonin to help us to be focus. Even though the caffeine or melatonin could help for us to degrade sleepiness, student still needed to sleep more to minus their stress.The second things that I though sleep was so important were “Sleep habits and susceptibility to the common cold,” stated “Poorer sleep efficiency and shorter sleep duration in the weeks preceding exposure to a rhinovirus were associated with lower resistance to illness.” (Sleep habits 3) and “Risks: Extra Sleep Is Found to Lower a Heart Risk ,” stated “sleeping an extra hour a night may help control coronary artery calcification, a major risk factor for heart disease.” (Risks 1) These two articles stated sleep could make us be more health. “Sleep duration, general and abdominal obesity, and weight change among the older adult population of Spain.,” stated sleep more than eight or night hour was associated with obesity and with short- term weight gain in women. (Sleep duration 6) if we did not sleep too much it would not be fat.
