Everyone feels tired sometimes. Fatigue is different: a lasting lack of energy that rest doesn't fix and that gets
in the way of daily life. It usually has an identifiable cause — often sleep, stress, anaemia, thyroid or blood
sugar — and most causes are treatable. Ayurveda calls tiredness without exertion Klama and treats it by
restoring digestion, routine and vitality (Ojas).
What is fatigue?
Fatigue can be physical (heavy limbs, weakness, breathlessness on effort), mental (poor concentration, low
motivation), or both. Short-lived tiredness after a late night, a busy week or a viral illness is normal and
passes. See a doctor if tiredness lasts more than 3–4 weeks, is getting worse, or comes with
any of the warning signs below.
Daylight, gentle movement and a steady daily routine support mood, sleep and energy — alongside, not instead of, professional care.
Common causes
Fatigue usually has more than one contributing cause. Most can be found with a history, an examination and simple blood tests.
Iron-deficiency anaemia — very common in India, especially in women, adolescents and vegetarians; causes tiredness, breathlessness, pale skin and hair loss.
Vitamin B12 deficiency — common in vegetarians and people on metformin or long-term acid medicines; can also cause tingling and memory problems.
Underactive thyroid and diabetes — both can begin with tiredness alone.
Sleep disorders — loud snoring with pauses in breathing (sleep apnoea) leaves people exhausted despite a full night in bed.
Depression, anxiety and prolonged stress.
After infections such as dengue, typhoid, COVID-19 or glandular fever, tiredness can linger for weeks. If it lasts for months and worsens after effort, see our page on chronic fatigue syndrome.
Warning signs — see a doctor promptly
Unexplained weight loss, fever or drenching night sweats
Breathlessness, chest pain, palpitations or fainting
Blood in stools, black stools, vomiting blood, or very heavy periods
New lumps, swollen glands, or a cough lasting more than 2 weeks
Excessive thirst and urination; yellow eyes; swelling of the legs
Low mood with hopelessness or thoughts of self-harm — call Tele-MANAS 14416
Tests & assessment
A doctor will ask about sleep, mood, diet, periods, medicines and alcohol, and examine you. Common first tests
include a complete blood count, ferritin (iron stores), blood sugar or HbA1c, thyroid function (TSH), kidney and
liver function, vitamin B12 and vitamin D, and sometimes an ESR/CRP, urine test or chest X-ray. Treatment follows
the cause — for example iron for anaemia, thyroid hormone for hypothyroidism, or a sleep study for suspected apnoea.
Ayurvedic view
Restore digestion (agni) and clear ama → balance the dosha → rebuild Ojas through rest, food and Rasayana.
Ayurveda distinguishes Shrama, the healthy tiredness that follows work, from Klama, fatigue
without exertion, which it treats as a sign of imbalance. Weak digestion producing ama leaves a heavy,
sluggish, Kapha-type fatigue; overwork, irregular meals and poor sleep give a restless, depleted,
Vata-type exhaustion; and overheating, anger and perfectionism burn out energy in a Pitta pattern.
The deeper goal is to protect Ojas — the essence of strength and immunity — which is depleted by chronic
stress, grief, illness and irregular living.
An energy routine
Fix your wake-up time, even at weekends, and get morning daylight within an hour of waking.
Sleep 7–8 hours; keep screens out of the last hour before bed.
Move a little every day — a 20–30 minute walk improves energy more than rest does for most causes of tiredness. Build up gradually.
Break up long sitting with a few minutes of movement every hour.
Pace demanding work and plan short breaks; say no to some commitments.
A short warm-oil self-massage (abhyanga) before bathing, and slow breathing (Nadi Shodhana), calm an overstretched Vata.
Diet
Eat regular meals — don't skip breakfast; include protein (dal, pulses, curd, eggs, paneer) at each meal.
Iron-rich foods: green leafy vegetables, beans, jaggery in moderation, dates, and meat or fish if you eat them — with vitamin C (amla, lemon, guava) to improve absorption. Avoid tea or coffee with meals, as it reduces iron uptake.
Vegetarians should ask their doctor about vitamin B12.
Drink enough water; limit caffeine after midday, sugary snacks and alcohol.
When digestion feels heavy, favour light, warm meals such as kitchari, soups and steamed vegetables for a few days.
Herbs & safety
Ayurvedic physicians use Rasayana herbs such as Ashwagandha, Shatavari, Guduchi
and Amalaki (the base of Chyawanprash) to support recovery. Start them only after
treatable medical causes have been checked — a tonic can mask anaemia or thyroid disease. Ashwagandha can
affect thyroid function and has rarely been linked to liver injury; Chyawanprash contains sugar, which
matters in diabetes. Use licensed products under a qualified practitioner's guidance.
