Constant fatigue is tiredness that does not improve with normal sleep and lasts for weeks. Common causes include iron deficiency anaemia, low vitamin D or B12, thyroid problems, diabetes, poor sleep, stress and dehydration. Start with a regular sleep routine, balanced meals, enough water, daily movement and stress control, and ask a doctor about basic blood tests if it persists.

Constant fatigue is tiredness that does not go away with a normal night's sleep and starts to affect work, study or family life. It usually has a cause that can be found, such as low iron, a vitamin deficiency, a thyroid problem, poor sleep, stress or dehydration. The best natural solutions start with sleep, food, water, movement and stress control, alongside simple blood tests if the tiredness lasts for weeks.
Feeling tired all the time is not laziness. Below, we explain the common reasons for low energy, how persistent fatigue differs from ordinary tiredness, why some people feel sleepy all day, what to ask your doctor, and where a traditional supplement like shilajit may fit as support.
Common Causes of Constant Fatigue
Fatigue can be physical (the body feels heavy and weak), mental (poor focus, slow thinking, brain fog) or emotional (linked to worry, sadness or burnout). Often it is a mix. The table below lists the most common medical and lifestyle reasons for low energy and what usually helps.
| Cause | Typical signs | What helps |
|---|---|---|
| Iron deficiency anaemia | Pale skin, breathlessness on stairs, fast heartbeat, headaches, hair fall, cold hands and feet | CBC and ferritin test, iron-rich foods, iron treatment if your doctor advises it |
| Vitamin D deficiency | Tiredness, bone or muscle aches, low mood, weak muscles | Vitamin D test, safe sunlight exposure, supplements if prescribed |
| Vitamin B12 deficiency | Tiredness, tingling or numbness in hands and feet, poor memory, sore tongue | B12 test, eggs, milk, meat and fish, injections or tablets if your doctor advises |
| Underactive thyroid | Slowness, weight gain, feeling cold, dry skin, constipation | TSH test and treatment from a doctor |
| Diabetes or high blood sugar | Thirst, passing urine often, tiredness after meals, slow-healing wounds | Blood sugar test, diet changes, medical follow-up |
| Poor sleep or sleep apnoea | Loud snoring, waking up tired, morning headaches, dozing during the day | Regular sleep routine, weight management, sleep assessment by a doctor |
| Stress, anxiety or depression | Low mood, loss of interest, broken sleep, overthinking | Talking to someone, relaxation habits, professional support |
| Dehydration | Headache, dizziness, dark urine, dry mouth, especially in summer | Regular water through the day, extra fluids in heat or after sweating |
| Medicines | Drowsiness that started after a new medicine | Ask your doctor or pharmacist; do not stop a medicine on your own |
| Long COVID or post-viral fatigue | Exhaustion after an infection, worse after effort, brain fog | Pacing activity, gradual return to exercise, medical review |
Lifestyle factors add to all of these: too much sugary and fried food, very little physical activity, long hours of screen time, smoking, and depending on tea, coffee or energy drinks to get through the day. For more on iron, see our guide to khoon ki kami ka ilaj (anaemia).
Persistent Fatigue vs Normal Tiredness
Normal tiredness has an obvious reason, such as a late night, a long journey or a hard day at work, and it improves after rest. Persistent fatigue is different:
- It continues for weeks even when you sleep enough.
- Rest does not refresh you, and small tasks feel draining.
- It comes with other signs such as breathlessness, low mood, weight change or poor concentration.
- It affects your ability to work, study or look after your family.
Extreme fatigue and exhaustion that comes on suddenly, or extreme tiredness that keeps getting worse, should always be checked by a doctor rather than managed at home alone.
Why Am I Sleepy All the Time? Causes of Excessive Sleepiness
Fatigue (lack of energy) and sleepiness (struggling to stay awake) often overlap but are not the same. If you nod off while reading, in meetings or, more seriously, while driving, the causes of excessive sleepiness are worth looking at carefully. Common reasons for too much sleepiness include:
- Not enough sleep or late nights: scrolling the phone in bed and irregular sleep times are the most common reasons.
- Poor-quality sleep: sleep apnoea, where breathing pauses during the night, often causes loud snoring and daytime sleepiness, especially in people who are overweight.
- Heavy meals: large, oily or very sugary meals, particularly at lunch, can leave you drowsy.
- Medical conditions: anaemia, thyroid problems, diabetes and depression can all cause more sleepiness.
- Medicines: some allergy, sleep, mood and blood pressure medicines can cause drowsiness.
- Shift work: working nights or changing shifts confuses the body clock.
- Rarer sleep disorders: such as narcolepsy, which needs a specialist assessment.
If you feel sleepy while driving, stop and rest, and speak to a doctor. Daytime sleepiness that is strong enough to affect safety should never be ignored.
Muscle Exhaustion and Fatigued Muscles
Muscle exhaustion is when your muscles feel heavy, weak or shaky and tire quickly. After a hard workout or physical labour, fatigued muscles are normal and recover with rest, fluids and food. It is less normal when muscles feel weak without effort or stay weak for weeks.
Common reasons include:
- Overtraining or not resting between workouts.
- Not eating enough protein or total food.
- Dehydration and loss of salts through heavy sweating in summer.
- Low vitamin D, low potassium or low magnesium.
- Anaemia, thyroid problems or uncontrolled diabetes.
To help muscles recover, eat protein at each meal (eggs, daal, chicken, yoghurt), drink enough fluids, sleep well and build up exercise gradually. If weakness affects one side of the body, comes on suddenly, or comes with dark urine or severe muscle pain, seek medical help urgently. For general weakness, read our guide on kamzori ka ilaj and natural remedies for weakness.
Natural Remedies for Fatigue: Sleep, Food, Water, Movement and Stress
For many people, the most effective natural remedies for fatigue are simple daily habits done consistently. These work best once medical causes have been ruled out or are being treated.
Fix your sleep routine
Sleep is the body's main recovery time. Go to bed and wake up at about the same time every day, including weekends. Keep your room dark, quiet and well ventilated, avoid heavy meals and tea or coffee late in the evening, and keep the phone away from the bed. If you need a daytime nap, keep it short so it does not disturb night sleep.
Eat balanced meals on time
Skipping breakfast and then eating a large, oily meal often leads to an energy crash. Regular meals with whole grains, protein, vegetables and fruit give steadier energy. Too much sugar, sweets and fried snacks give a short lift followed by more tiredness.
Drink enough water
Mild dehydration is one of the most ignored causes of tiredness and headaches, particularly in Pakistani summers. Sip water through the day, and add lassi, lemon water, coconut water or ORS after heavy sweating. Sugary fizzy drinks and too much tea or coffee are not good substitutes.
Move your body, even when tired
It sounds backwards, but light activity usually increases energy. A daily brisk walk, stretching, cycling, yoga or simple home exercise improves blood flow, mood and sleep. If you sit for long hours, stand up and move for a few minutes regularly. If you have post-viral fatigue, increase activity slowly and stop before you are exhausted.
Manage stress and mental fatigue
Overthinking, money or family pressure and heavy workloads drain mental energy and disturb sleep. Deep breathing, journaling, time in nature or sunlight, and talking to a trusted friend or family member can help. Balance work with rest and family time; working without breaks leads to burnout. If low mood or anxiety does not lift, speak to a doctor or counsellor.
Cut back on caffeine, screens and smoking
Many cups of tea, coffee or energy drinks give short alertness but can cause anxiety, poor sleep and more fatigue later. Reduce slowly and swap some cups for water, herbal tea or warm milk. Take regular breaks from screens while working, avoid scrolling before bed, and stop smoking, which lowers the oxygen your blood can carry.
Energy Foods: Pakistani Examples
You do not need expensive products to eat for energy. Everyday Pakistani foods can cover most needs:
| Nutrient | Why it matters | Pakistani food examples |
|---|---|---|
| Iron | Carries oxygen in the blood | Palak, chanay, daal, kaleji, beef and mutton, dates |
| Vitamin C | Helps the body absorb iron from plant foods | Lemon, oranges (kinnow), guava, amrood, tomatoes |
| Vitamin B12 | Needed for red blood cells and nerves | Eggs, milk, dahi, chicken, fish, meat |
| Protein | Supports muscle strength and recovery | Eggs, daal, chanay, chicken, fish, yoghurt |
| Slow-release carbohydrates | Gives steady energy without a crash | Whole wheat roti, oats, daliya, brown rice |
| Magnesium and healthy fats | Support muscle and nerve function | Almonds, walnuts, pumpkin seeds, leafy greens |
| Potassium | Helps muscles and fluid balance | Bananas, potatoes, dates, coconut water |
A squeeze of lemon on daal or palak, or a piece of fruit after a meal, helps you absorb more iron. Avoid drinking tea straight after meals, as it can reduce iron absorption. Honey and dates can give quick energy, but keep portions moderate, especially if you have high blood sugar.
Treatment for Fatigue and Tiredness: Tests to Ask Your Doctor
If tiredness lasts more than a few weeks despite better sleep and diet, the right treatment for fatigue and tiredness depends on finding the cause. Before trying many supplements, ask your doctor whether these basic blood tests are suitable for you:
- CBC (complete blood count): checks haemoglobin for anaemia and signs of infection.
- Ferritin: shows your iron stores, which can be low even when haemoglobin is normal.
- Vitamin D: deficiency is common in people who spend little time in sunlight.
- Vitamin B12: especially important for vegetarians, older adults and people on long-term stomach or diabetes medicines.
- TSH: screens for an underactive or overactive thyroid.
- Blood sugar (fasting sugar or HbA1c): checks for diabetes or prediabetes.
Your doctor may also check kidney and liver function or other tests based on your symptoms. Correcting a confirmed deficiency is often the single biggest step towards better energy. Only take iron or high-dose vitamins on medical advice, because too much can cause harm.
When to See a Doctor
See a doctor if tiredness lasts more than a few weeks, keeps getting worse, or affects daily life. Seek urgent medical help if fatigue comes with any of these red flags:
- Chest pain, a racing or irregular heartbeat, or shortness of breath.
- Fainting, severe dizziness or confusion.
- Unexplained weight loss, fever or night sweats.
- Blood in stools or vomit, black stools, or very heavy periods.
- Sudden weakness in the face, arm or leg, or difficulty speaking.
- Extreme thirst and passing urine very often.
- Low mood with thoughts of self-harm; please contact a doctor or emergency service straight away.
Older adults, pregnant women and people with long-term conditions such as heart disease, kidney disease or diabetes should get new fatigue checked sooner.
Where Shilajit Fits
Shilajit (salajeet) is a mineral-rich resin used for generations in traditional medicine in the mountains of Chitral and Gilgit-Baltistan. It is not a treatment for fatigue, and it does not replace sleep, good food or medical care. Once the basics are in place, some adults choose it as a supplement that may support general energy and stamina.
The research is limited:
- Keller et al. (2019): in a study of active men, taking 500 mg of shilajit a day for eight weeks helped them retain muscle strength after a fatiguing exercise test. This was a small study in healthy men, so it cannot be applied to everyone with fatigue.
- Surapaneni et al. (2012): this was an animal study in rats, which suggested shilajit reduced signs of chronic fatigue. Animal results often do not carry over to people.
- Wilson et al. (2011): a review that noted much of shilajit's reported activity still lacks substantial evidence.
If you have anaemia, iron treatment from your doctor comes first; our article on shilajit and iron deficiency explains what is and is not known. A typical serving is 300 to 500 mg a day, about the size of a pea, dissolved in warm water or milk; see how to take shilajit resin for details.
Shilajit is not suitable for pregnant or breastfeeding women or children. Speak to your doctor first if you take medicines for blood pressure, diabetes or blood thinning, or have kidney disease, gout or iron overload. Read our shilajit side effects and precautions guide before starting.
If you decide to try it, our lab-tested 10g pure shilajit resin is a sensible starting size, and the full range is in our shilajit resin collection.
FAQs
What is the main cause of constant fatigue?
There is no single cause. The most common reasons are poor sleep, stress, an unbalanced diet, dehydration and low activity, followed by medical causes such as iron deficiency anaemia, vitamin D or B12 deficiency, thyroid problems and diabetes. Simple blood tests can rule out the medical causes.
What are the best natural remedies for fatigue?
A regular sleep routine, balanced meals with iron and protein, enough water, daily light exercise and stress management are the most reliable natural remedies for fatigue. Cutting back on caffeine, late-night screens and smoking also helps. If tiredness continues, see a doctor rather than adding more supplements.
What are the reasons for too much sleepiness during the day?
Common reasons for excessive sleepiness include late nights, poor-quality sleep from snoring or sleep apnoea, heavy meals, shift work and some medicines. Anaemia, thyroid problems, diabetes and depression can also cause it. If you feel sleepy while driving or at work, speak to a doctor.
Why do my muscles feel tired and weak all the time?
Fatigued muscles can come from overtraining, too little protein, dehydration, or low vitamin D, potassium or magnesium. Anaemia and thyroid problems can also cause muscle exhaustion. If weakness is sudden, on one side, or comes with severe pain or dark urine, get urgent medical help.
What is the treatment for fatigue and tiredness?
Treatment depends on the cause. Lifestyle changes help most people, while confirmed problems such as anaemia, vitamin deficiencies or thyroid disease need treatment from a doctor. Ask about a CBC, ferritin, vitamin D, B12, TSH and blood sugar test if tiredness lasts for weeks.
Is extreme tiredness a sign of something serious?
Often it is not, but extreme fatigue and exhaustion with chest pain, breathlessness, fainting, weight loss, fever or bleeding needs prompt medical attention. Tiredness that steadily worsens over weeks should also be checked.
Can shilajit help with constant tiredness?
Shilajit may support general energy and stamina, but the evidence is limited, and one of the fatigue studies was only in animals. It works best, if at all, alongside good sleep, diet and medical care, not instead of them. Check with your doctor first if you have a health condition or take regular medicines. If tiredness comes with poor memory and focus, our guide to dimagi kamzori ka ilaj may also help.
