Introduction Quite a large number of American workers as well as all workers around the world have experienced fatigue and stress at work. Studies have shown that there is constant relation between the health of an individual and the person’s productivity at work. Fatigue seems to be more common to women which can be attributed to their diverse duties. Apart from office work, women always have other duties when they get home from work such as cooking, looking for the wellbeing of their children and husbands. For instance, after work, a woman may pass through the shopping mall on her way from work, she may be the one cooking once she gets home or she may wake up earlier than the husband in the morning to prepare the children to go to school as well as preparing the husband for work by making him breakfast or getting his clothes ready. By the time she gets to work she will be already tired and may be sleepy for getting up early and reluctant to perform office duties opposed to men who have fewer duties to perform besides office work. The result of fatigue is a great percentage of productivity which may lead to low income returns (Cable,1). Causes of fatigue Fatigue is caused by many factors in our daily life activities. Lack of enough sleep is a major contributing factor to fatigue with many people sleeping for less than seven hours which should be the minimum length of sleep by adults. The cause of inadequate sleep may result from extended working hours where many working people today continue with their office work at home especially at night since they get out of office late in the evening. As a result they end up consuming their time for sleep leaving only few hours for rest (Michael, 1). Others may not continue with office work at home but may attend to other personal business at that time leaving them no time to get the required sleep. Most companies are now having irregular working hours forcing them to organize shifts for workers. Those whose shifts are at night are the most affected because they go to work at night and during their free time which is daytime, they always find it difficult to sleep but rather find other income generating activities and they end up sleeping for only few hours or not sleeping at all. With the economy inflating greatly, many people are resolving to have more than one job. For instance, a university professor may be a university lecturer shift during the day and a night shift doctor at the same time. Such an individual finds it difficult to create time to relax and sleep and as a result he is always tired and having fatigue which is more likely to bring inefficiency in work. In other cases, some people may get the time to sleep and relax but fail to do so mainly because they are stressed may be from workplace stress or their own stress. Others may not even be stressed but may be suffering from sleeping disorders where affected individuals generally lack sleep for no particular reason and they may go to the extremes of staying awake until morning during which they have to go to work. Shift work may also disrupt the normal sleeping rhythms where one gets used to staying awake at night to the point where he cannot find sleep even when the person gets the time to do it. Age may also be a factor contributing to inadequacy in sleep with many teenagers sleeping late at night compared to the middle aged ad
