Fatigue is a universal phenomenon experienced by both healthy and sick people. It is a subjective, multi-factorial and multidimensional phenomenon. It is considered an unpleasant physical sensation, with cognitive and emotional components, described as tiredness that is not relieved with common strategies to restore energy. Its duration and intensity vary and it reduces, to different extents, the ability to perform usual activities. Cognitive fatigue, an increasingly common human condition that results from sustained cognitive engagement that taxes people’s mental resources. Persistent cognitive fatigue has been shown to lead to burnout at work, lower motivation, increased distractibility, and poor information processing. In addition, cognitive fatigue is detrimental to individuals’ judgments and decisions, even those of experts.

For many students, reading is a skill that eludes them for a variety of reasons. Cognitive processes such as working memory and phonological processing can account for some of the variability in reading comprehension. These processes allow the reader to not only decode words but access memory “stores” to understand written text. Readers also rely on lexical knowledge and reading strategies to comprehend the specific words they have read. Additionally, a reader’s motivation too can influence reading comprehension. Reading is essential not only to school success but for other reasons as these (e.g., getting a job or further studies). Understanding which factors are most important to reading comprehension is vital to inform instructional practices so that students are able to make academic progress that will ensure they have avenues for academic success. Fatigue is extreme tiredness resulting from mental or physical exertion or illness. It is also the weakness in metal or other materials caused by repeated variations of stress. Fatigue is a feeling of constant tiredness or weakness and can be physical, mental or a combination of both. It can affect anyone, and most adults will experience fatigue at some point in their life. Overall, fatigue is a term used to describe an overall feeling of tiredness or lack of energy. It isn’t the same as simply feeling drowsy or sleepy. When you’re fatigued, you have no motivation and no energy. Being sleepy may be a symptom of fatigue, but it’s not the same thing. Fatigue is a common symptom of many medical conditions that range in severity from mild to serious. It’s also a natural result of some lifestyle choices, such as lack of exercise or poor diet. If your fatigue doesn’t resolve with proper rest and nutrition, or you suspect it’s caused by an underlying physical or mental health condition, see your doctor. They can help diagnose the cause of your fatigue and work with you to treat it. Physical fatigue concerns the inability to exert force with ones muscles to the degree that would be expected. It may be an overall tiredness of the whole body, or be confined to particular muscle groups. Physical fatigue most commonly results from physical exercise or loss of sleep. Physical fatigue often leads to mental fatigue. Mental fatigue, which may include sleepiness, concerns a general decrease of attention and ability to perform complex, or even quite simple tasks with customary efficiency. Mental fatigue often results from loss or interruption of the normal sleep pattern. Sleep patterns are naturally associated with the body's circadian rhythms. Shift patterns and transit across time zones can interrupt circadian rhythms. SYMPTOMS OF FATIGUE Chronic tiredness or sleepiness. Headache. Dizziness. Sore or aching muscles. Muscle weakness. Slowed reflexes and responses. Impaired decision-making and judgment. Moodiness, such as irritability. CAUSES OF FATIGUE Fatigue can have causes that aren't due to underlying disease. Examples include lack of sleep, heavy exertion, jet lag, a large meal or ageing. The wide ranges of causes that can trigger fatigue include: Medical causes – unrelenting exhaustion may be a sign of an underlying illness, such as a thyroid disorder, heart disease or diabetes. Lifestyle-related causes – alcohol or drugs or lack of regular exercise can lead to feelings of fatigue. Workplace-related causes – workplace stress can lead to feelings of fatigue Emotional concerns and stress – fatigue is a common symptom of mental health problems, such as depression and grief, and may be accompanied by other signs and symptoms, including irritability and lack of motivation. Fatigue can also be caused by a number of factors working in combination. MEDICAL CAUSES OF FATIGUE There are a number of diseases and disorders which trigger fatigue. If you experience prolonged bouts of fatigue, consult your doctor. LIFESTYLE-RELATED CAUSES OF FATIGUE Common lifestyle factors that can cause fatigue include: Lack of sleep – typically adults need about eight hours of sleep each night. Some people try to get by on fewer hours of sleep. Too much sleep – adults sleeping more than 11 hours per night can lead to excessive daytime sleepiness. Alcohol and drugs – alcohol is a depressant drug that slows the nervous system and disturbs normal sleep patterns. Other drugs, such as cigarettes and caffeine, stimulate the nervous system and can cause insomnia. Sleep disturbances – disturbed sleep may occur for a number of reasons, for example, noisy neighbors, young children who wake in the night, a snoring partner, or an uncomfortable sleeping environment such as a stuffy bedroom. Lack of regular exercise and sedentary behaviour – physical activity is known to improve fitness, health and wellbeing, reduce stress, and boost energy levels. It also helps you sleep. Poor diet –low carbohydrate diets or high energy foods that are nutritionally poor don’t provide the body with enough fuel or nutrients to function at its best. Quick fix foods, such as chocolate bars or caffeinated drinks, only offer a temporary energy boost that quickly wears off and worsens fatigue. Individual factors – personal illness or injury, illnesses or injuries in the family, too many commitments (for example, working two jobs) or financial problems can cause fatigue. WORKPLACE-RELATED CAUSES OF FATIGUE Common workplace issues that can cause fatigue include: Shift work – the human body is designed to sleep during the night. This pattern is set by a small part of the brain known as the circadian clock. A shift worker confuses their circadian clock by working when their body is programmed to be asleep. Poor workplace practices – can add to a person’s level of fatigue. These may include long work hours, hard physical labour, irregular working hours (such as rotating shifts), a stressful work environment (such as excessive noise or temperature extremes), boredom, working alone with little or no interaction with others, or fixed concentration on a repetitive task. Workplace stress – can be caused by a wide range of factors including job dissatisfaction, heavy workload, conflicts with bosses or colleagues, bullying, constant change, or threats to job security. Burnout – can be described as striving too hard in one area of life while neglecting everything else. ‘Workaholics’, for example, put all their energies into their career, which puts their family life, social life and personal interests out of balance. Unemployment – financial pressures, feelings of failure or guilt, and the emotional exhaustion of prolonged job hunting can lead to stress, anxiety, depression and fatigue. PSYCHOLOGICAL CAUSES OF FATIGUE Depression – this illness is characterized by severe and prolonged feelings of sadness, dejection and hopelessness. People who are depressed commonly experience chronic fatigue. Anxiety and stress – a person who is chronically anxious or stressed keeps their body in overdrive. The constant flooding of adrenaline exhausts the body, and fatigue sets in. Grief – losing a loved one causes a wide range of emotions including shock, guilt, depression, despair and loneliness. FATIGUE TYPES There are three types of fatigue: transient, cumulative, and circadian: Transient fatigue is acute fatigue brought on by extreme sleep restriction or extended hours awake within 1 or 2 days. Cumulative fatigue is fatigue brought on by repeated mild sleep restriction or extended hours awake across a series of days. Circadian fatigue refers to the reduced performance during nighttime hours, particularly during an individual’s “window of circadian low” (WOCL) (typically between 2:00 a.m. and 05:59 a.m.). READING COMPREHENSION Reading comprehension is the process by which we understand the texts we read. It is the purpose of reading, why we teach it, and why we care about it. It is also the prerequisite for meaningful learning from text. Comprehension is the understanding and interpretation of what is read. Readers who have strong comprehension are able to draw conclusions about what they read, what is important, what is a fact, what caused an event to happen, which characters are funny and so on Reading comprehension is also the process of creating meaning from text. The purpose is to get an understanding of the text rather than to acquire meaning from individual words or sentences. The outcome of reading comprehension is the mental representation of a text meaning that is combined with the readers’ previous knowledge. FATIGUE AND READING COMPREHENSION Fatigue is a term used to describe an overall feeling of tiredness or lack of energy. It isn’t the same as simply feeling drowsy or sleepy. When you’re fatigued, you have no motivation and no energy. Being sleepy may be a symptom of fatigue, but it’s not the same thing. However, at some point in school student begins to feel tired or fatigued while reading, comprehension recall goes down immensely. The extra load imposed on cognitive processing systems causes the reader to be more focused on their fatigue than the reading material. This syndrome is marked by symptoms of eyestrain, headaches, dry eyes, and neck pain. “When reading paper text, the haptic modality might offload some cognitive demands onto the visual modality, thereby alleviating visual fatigue”. When a reader is less focused on their fatigue, more cognitive ability is allotted to understanding the text. Therefore, when student feel fatigued, it becomes difficult to comprehend while reading and when comprehension is not attained while reading, is a total waste of time. In conclusion, it is important that students study their body and know when they are fatigued so as to take the appropriate rest or seek medical attention. Since paying less attention to your body when fatigued can lead to some underlying illnesses and consequences inclusive of reading comprehension difficulty.
