Brain, nerves & sleepAnswered 15 September 2026

I sleep eight hours but still feel tired the whole day. Is this weakness?

Asked by a patient, 29 — Karachi

Constant tiredness after full sleep is usually not weakness. In most cases it points to poor sleep quality, low iron, or an unbalanced routine. Get your haemoglobin and vitamin D checked first, then look at your meal timings and screen time before bed.
