The feeling of fatigue is usually a state of drowsiness or exhaustion that makes a person feel less able to carry out physical or mental activities.
Fatigue can have a variety of causes and can be temporary or long-term, but is usually caused by a combination of factors, including:
Sleep deprivation: if a person does not get enough sleep, sleep deprivation can cause tiredness and drowsiness.
Stress: Increased stress or anxiety can cause fatigue due to the brain’s constant functioning.
Exercise: Intense exercise, especially if the person is not used to it, is associated with fatigue.
Poor eating habits: unhealthy food and insufficient fluid intake do not provide enough nutrition for healthy body function, which can lead to tiredness.
Medical conditions: several medical conditions can cause fatigue, including thyroid problems, anaemia, low blood pressure and malnutrition.
Medications: certain medications, such as antihistamines, antidepressants and blood pressure medications, can also cause tiredness
There are different types of fatigue, which have different causes.
Here are some of them:
General fatigue: this is the most common type, causing a general feeling of exhaustion and drowsiness. It is usually caused by lack of sleep or stress.
Mental fatigue: this condition can be the result of intense brain work. This includes lack of concentration, difficulty remembering and reduced decision-making.
Physical fatigue: Fatigue resulting from physical activity, which may be caused by exercise and heavy physical work. In this case, the body and muscles become fatigued.
Chronic fatigue syndrome: a condition characterised by constant exhaustion and fatigue that is not relieved by rest or sleep. The exact causes are unknown, but chronic tiredness syndrome may be linked to immune system problems and lifestyle.
Mood fatigue: This condition is often caused by depression or emotional stress. Mood tiredness is a condition in which a person feels exhausted, loses interest in life and has difficulty with motivation and energy.
Weather-related tiredness: some people may feel tired and sleepy when the weather changes, for example on rainy or overcast days. Although we don’t fully understand the cause, experts believe that this tiredness may be due to changing times of day, lack of light or changes in barometric pressure.
