Fatigue can have a variety of causes. Some conditions that cause fatigue include thyroid disorders, iron deficiency anemia, diabetes, chronic fatigue syndrome, and COVID-19. Some other causes of fatigue may involve your diet, sleep, and levels of stress.
Most of the time fatigue can be traced to one or more of your habits or routines, particularly lack of exercise. It's also commonly related to depression. On occasion, fatigue is a symptom of other underlying conditions that require medical treatment.

Call for an appointment with your doctor if your fatigue has persisted for two or more weeks despite making an effort to rest, reduce stress, choose a healthy diet and drink plenty of fluids.
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.
But if you're always feeling tired, it can be more than just not getting enough sleep. Feeling tired can stem from more serious issues like sleep apnea, depression, diabetes or chronic kidney disease. Family medicine specialist Jared Ankerman, MD, discusses the different reasons you might be feeling so tired.
Working while fatigued can be dangerous. Research suggests that the effects of fatigue on the brain are as harmful as drunk driving. Fatigue affects employees' memory, balance, concentration, decision-making, and motor skills. It also causes about 13% of workplace accidents and injuries each year.
This sleep inertia, or transition from sleep to wake that comes with temporary grogginess, is part of the natural sleep-wake cycle. Sleep inertia typically lasts for 60-90 minutes. Natural light, exercise, coffee, and low sleep debt can help reduce its length and severity.
The eight B vitamins (thiamin, riboflavin, niacin, pantothenic acid, B6, biotin, folate and B12) provide the most energy, as they aid in cell metabolism, help the body transform carbohydrates and fats into energy and carry energy-nutrients around the body.
For most people, feeling tired when you wake up is the result of sleep inertia, which is a natural feeling you experience as you transition between being asleep and awake. This feeling generally dissipates between 15 and 60 minutes after waking, but for some it can last longer.
Chances are, your morning grogginess is just sleep inertia, which is a normal part of the waking process. Your brain typically doesn't instantly wake up after sleeping. It transitions gradually to a wakeful state. During this transition period, you may feel groggy or disoriented.
Most likely, you're still tired after eight hours of sleep because of these three factors: (1) you don't know your sleep need, (2) you're not taking into account your sleep efficiency, and (3) you carry sleep debt.
Endurance can decline as you age — and you can tire more quickly — but fatigue is not a natural part of aging.
The common symptoms include sleep problems muscle or joint pain, headaches, feeling dizzy or sick and fast or irregular heartbeats (heart palpitations) but there are many more, which can often be exaggerated by exercise.
But myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) isn't just being tired. It's a new state of fatigue that has lasted for at least 6 months and can be so severe that it gets in the way of your normal daily activities, at home and at work. Rest and sleep don't seem to help.
When are we considered old? For women, the old age threshold is about 73; for men, 70.
According to the research, the average American starts feeling old at the age of 47. Similarly, the average respondent starts to really worry about age-related bodily changes around 50 years old.
Ageing, an inevitable process, is commonly measured by chronological age and, as a convention, a person aged 65 years or more is often referred to as 'elderly'.
The most common cause of sleepiness is not sleeping long enough. Getting enough restful sleep is crucial for maintaining good health. Research over the past decade has shown that healthy sleep is just as important as exercising regularly and eating a healthy diet.
