There are many reasons why you might feel tired all the time, including:
- You might not be getting enough sleep, or your quality of sleep is poor. This could be due to shift work, family demands, study, or social life. Other causes include sleep disorders, snoring, or drinking too much caffeine.
- You might not be getting enough exercise, or you might be exercising too much. You might also have an unhealthy diet, or be overweight or obese.
- Stress can be caused by life challenges, such as bereavement or looking after a new baby. It can also be caused by work-life imbalance, such as long working hours or not having enough time to relax.
- You might be experiencing depression, anxiety, or emotional exhaustion.
- Some medications, like chemotherapy, can cause drowsiness.
- You might have anemia, sleep apnea, an underactive thyroid, or chronic kidney disease.
- You might not be drinking enough liquids to replace what you lose through sweat, urine, stools, and breath.
- You might be lacking certain nutrients, like vitamin B12, folate, vitamin D, iron, or magnesium.
