FATIGUE: is the reduction in energy as a result of physical/mental work or weariness from labour or exertion. Fatigue may be physical/physiological or mental/ psychological. In physical or physiological fatigue, the individual’s ability can only be regained through rest, because the individual is physically tired.
Mental or psychological fatigue could result from or in a person’s dislike of a particular task. This dislike then prevents work from being accomplished, though the physical energy for work may be in the form of boredom or frustration. Boredom is characterized by yawning, restlessness and a desire to stop the work being done, though the capacity to do work is not changed.
TYPES OF FATIGUE
There are two types of fatigue
1. Physical fatigue which results from doing work with the hands or any other part of the body.
2. Psychological or mental fatigue which may result from concentration or attention on a situation for too long such as sewing or reading. Others include:
Listener fatigue: listening devices with earphones that seal the ear canal can lead to listening fatigue.
Age fatigue: advance age has an effect on both the body and the brain.
Pregnancy Fatigue: normal fatigue can occur with childbearing .women often feel exhausted during the early stages of pregnancy.
PREVENTION OF FATIGUE
Avoid doing too many things at the same time.
Have enough rest.
Eat adequate and regular meals.
Alternate tasks that require much energy with those that require less.
Break big tasks into smaller ones and do them in bits.
Use the best method for every task.
Take the best posture for each task when doing it.
Do not overwork yourself.

LINKING ENERGY TO TIME MANAGEMENT:
Energy is often interwoven with time planning. For instance, alternating light with heavy jobs, including rest periods at specific times of the day and deciding what part of the day to use for certain tasks, are decisions leading to both time and energy planning.
FACTOR THAT AFFECT ENERGY USE
1. Age: the older an adult gets, the less able he is to do certain types of work
2. Physical handicap: a person who is physically handicapped, lame, crippled or in a wheel chair, is likely to spend more energy doing some household tasks than a person without any disability.
3. Attitude/Emotion: A home-maker who says she is tired may suddenly feel capable of preparing a meal when her husband arrives home from a long journey.
4. Health: A sick person or an invalid does not usually have as much strength or energy to do household tasks as a physically healthy person would have.
