1. Inadequate Sleep Quality
Even when you log 7‑8 hours, poor sleep architecture can leave you exhausted. Tips: keep a cool, dark bedroom and avoid screens 30 minutes before bed.
2. Iron Deficiency
Low ferritin reduces oxygen transport. Include iron‑rich foods (red meat, lentils) and pair with vitamin C to improve absorption.
3. Hidden Food Intolerances
Gluten or dairy sensitivities can trigger inflammation and fatigue. An elimination diet for 2‑3 weeks can reveal culprits.
4. Chronic Stress
Elevated cortisol disrupts mitochondrial function. Mind‑body practices like meditation or short walks restore balance.
5. Dehydration
Even mild dehydration impairs cognitive performance. Aim for ~2 L water daily, more with exercise.
6. Thyroid Imbalance
Sub‑clinical hypothyroidism often presents as fatigue. Check TSH levels if other causes are ruled out.
7. Vitamin D Deficiency
Low vitamin D is linked to low energy. Supplement 1,000–2,000 IU daily after testing.
