Answer the questions above
Your likely energy drains, and the tests worth discussing with a doctor, will appear here.This check points you towards common, fixable causes. It isn’t a diagnosis. Only a doctor and blood tests can confirm what’s behind your tiredness.
8 common reasons you’re always tired
1. Too little (or poor) sleep
Most adults need 7–9 hours. Late-night scrolling delays sleep, and phone light disturbs your body clock, so even 8 hours in bed can leave you groggy.
Signs: hard to wake, need tea to function, crash after lunchFix: same wake-up time daily, no phone for 30 minutes before bed, dark and cool room2. Iron-deficiency anaemia
Low iron means less oxygen reaches your muscles and brain. It’s very common in Indian women, especially with heavy periods or after pregnancy, and in vegetarians.
Signs: breathless on stairs, pale skin, hair fall, cold hands, craving iceFix: CBC and ferritin test. Eat iron-rich foods (dal, chana, green leafy vegetables, jaggery) with vitamin C, and avoid tea with meals3. Low vitamin B12
B12 comes mainly from animal foods, so vegetarians with little dairy are at higher risk. Long-term use of the diabetes drug metformin and of acidity pills can also lower it.
Signs: tingling hands and feet, poor memory, low mood, mouth ulcersFix: B12 blood test. Milk, curd, paneer and eggs help, and doctors often prescribe supplements4. Low vitamin D
Despite all the sunshine, indoor jobs, covered skin and pollution mean nearly half of Indians tested are deficient.
Signs: body aches, low back pain, weak muscles, frequent illnessFix: 15–30 minutes of mid-morning sun on your arms and face, plus a vitamin D test. Only take high-dose supplements on a doctor’s advice5. An underactive thyroid
Hypothyroidism slows your whole metabolism. It’s more common in women and often goes undiagnosed for years.
Signs: weight gain, feeling cold, dry skin, constipation, puffy faceFix: a simple TSH blood test. Treatment is usually one daily tablet6. Not drinking enough water
Even mild dehydration lowers your concentration and energy, and Indian heat, AC offices and too much tea or coffee make it worse.
Signs: headaches, dark yellow urine, dizziness when standing upFix: 2–3 litres a day (more in summer). Aim for pale yellow urine7. Blood-sugar crashes
Meals heavy on white rice, maida, biscuits and sweet chai spike your blood sugar, then drop it, and you feel sleepy. Constant tiredness with thirst can also be a sign of diabetes.
Signs: sleepy after meals, sugar cravings, very thirsty, urinating oftenFix: add protein and fibre to each meal, and get an HbA1c test if you have symptoms or a family history8. Stress, low mood and sitting all day
Mental load and long hours at a desk are big, underrated energy drains. Fatigue is also a common symptom of anxiety and depression.
Signs: tired but wired, poor sleep, no motivation, feeling low most daysFix: a 20-minute daily walk, short breaks every hour, and talking to a doctor or counsellor if low mood lasts more than 2 weeksA simple 7-day energy reset
| Day | One change to make |
|---|---|
| 1 | Fix your wake-up time, even on weekends. Get 10 minutes of morning sunlight |
| 2 | Keep your phone out of the bedroom, or at least 30 minutes before sleep (always tired) |
| 3 | Drink a glass of water before every cup of tea or coffee. No caffeine after 4 pm |
| 4 | Add protein to breakfast: eggs, besan chilla, curd, sprouts or paneer |
| 5 | Take a 20-minute brisk walk, ideally after lunch or dinner |
| 6 | Swap one refined-carb snack for fruit, roasted chana or nuts |
| 7 | Book a basic blood test: CBC, ferritin, B12, vitamin D, TSH and HbA1c |
Many diagnostic labs in India offer these tests together as a “full body” or “fatigue” package. Compare prices, and ask your doctor which tests you actually need.
- unexplained weight loss, fever or night sweats
- breathlessness, chest pain or a racing heartbeat (always tired)
- very heavy periods, or blood in your stool or urine
- tiredness that hasn’t improved after 2–4 weeks of good sleep
- feeling hopeless or low most days. You can also call Tele-MANAS on 14416, the government’s free mental-health helpline
FAQ
Why am I tired even after 8 hours of sleep?
The quality of your sleep, not just the hours, matters. Late screens, loud snoring (a possible sign of sleep apnoea), alcohol or an irregular schedule can all spoil it. If your habits are fine, low iron, B12, vitamin D or thyroid problems are the most common medical causes.
Which blood tests should I get for constant tiredness?
Doctors commonly check a complete blood count (CBC), ferritin (iron stores), vitamin B12, vitamin D, TSH (thyroid) and HbA1c (blood sugar). Your doctor may add others based on your symptoms.
Can I just take a multivitamin?
It might help a little, but it can hide the real problem, and large doses of some vitamins such as vitamin D can be harmful. Test first so you treat the actual deficiency at the right dose.
Does tea or coffee make tiredness worse?
It can. Caffeine late in the day spoils sleep, and tea with meals reduces how much iron you absorb. Keep tea and coffee to the morning and early afternoon, and have it between meals rather than with them. (always tired)
