Fatigue is usually caused by stress, anxiety, depression, viruses — such as the flu or COVID-19 — or sleep problems. Some medications may also cause you to feel fatigued. Sometimes fatigue is a symptom of a physical condition such as: anaemia — not having enough iron in your blood.
The reason you're tired in the morning could also just be part of your normal waking up process. The period between opening your eyes and actually feeling energized is called sleep inertia. "It can take anywhere from 15 minutes to an hour (or even two hours in extreme cases) to feel like a functioning person," says Dr.
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.

Teens (14-17 years) require about eight to 10 hours of nightly sleep. Adults: Between the ages of 18 and 64, adults should aim for seven to nine hours of nightly sleep. If you're older than 65, you may need a little less: seven to eight hours is recommended.
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.
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. Lifestyle changes can often improve feelings of fatigue in these situations.
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.
The inability to get out of bed is a common symptom of someone suffering from a mental health disorder or substance use disorder.

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.
One possible reason for feeling tired, anxious, and weak is having low levels of iron, vitamin D, or B12. Many experts believe that a significant percentage of the U.S. population is deficient in vitamin D. Having low levels of vitamin D can cause muscle weakness and pain.
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.
