Many possible factors cause chronic fatigue, such as underlying medical conditions, nutrient deficiencies, sleep disturbances, caffeine intake, and chronic stress. If you're experiencing unexplained fatigue, it's important to talk with your doctor to find the cause.
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.
The two most likely reasons you're always so tired no matter how much sleep you get are you've got high sleep debt or you're not living in sync with your circadian rhythm. You may also feel sleepy if you're ill, pregnant, or you've got a medical condition like anemia or diabetes.
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.
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.
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.
Lack of energy is a typical symptom for most major diseases, like heart disease, many types of cancer, autoimmune diseases such as lupus and multiple sclerosis, and anemia (too few red blood cells). Fatigue also is a common sign of depression and anxiety. And fatigue is a side effect of some medications.
What is vitamin B-12? Vitamin B-12, or cobalamin, is a nutrient you need for good health. It's one of eight B vitamins that help the body convert the food you eat into glucose, which gives you energy. Vitamin B-12 has a number of additional functions.
Disease and infection: Cancer, kidney disease and multiple sclerosis are just a few diseases that cause fatigue. Fatigue can also be a sign of infections such as mononucleosis, HIV and flu. Mental health conditions: Fatigue from depression or anxiety may make it difficult or impossible to perform daily activities.
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.
But tiredness or exhaustion that goes on for a long time is not normal. It can affect your ability to get on and enjoy your life. Unexplained tiredness is one of the most common reasons for people to see their GP.
This discrepancy is often due to a heightened state of sleep inertia, a circadian process that modulates memory, mood, reaction time and alertness upon waking, according to a 2015 study. Some people experience impaired performance and grogginess in this period after first turning off the alarm.
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.
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.
So does vitamin B12 give you energy? While B12 doesn't directly provide energy, it does give the body the tools it needs to convert food molecules into energy. Getting the recommended daily amount of B12 can therefore help ensure that the body is able to make the energy it needs to do everything you need it to do.
B vitamins help create energy in cells. Having a deficiency in B vitamins can cause fatigue . Older adults, vegetarians, and vegans may be at higher risk of a vitamin B-12 deficiency , as it is only in animal products or fortified foods. A B-12 deficiency can cause anemia, making people feel low in energy.
People may feel fatigued in body or mind (physical or psychological fatigue). Most of the time, fatigue can be traced to one or more of your habits or routines. Fatigue can be a normal and important response to physical exertion, poor eating habits, emotional stress, boredom, or lack of sleep.
Magnesium plays many crucial roles in the body, such as supporting muscle and nerve function and energy production.
