Experts Explain Causes of Fatigue Despite Adequate Sleep Duration

Feeling tired despite 7-8 hours of sleep can result from factors beyond sleep duration, including nutrient deficiencies and cognitive overload. Nutritionist Lovneet Batra highlights that low levels of vitamin B12 and iron may cause fatigue and reduced energy. Neurologist Dr. Aniruddha More emphasizes that sleep quality, depth, and consistency are crucial for restoration. Additionally, mental exhaustion often stems from cognitive overload rather than true fatigue, requiring intentional rest beyond passive activities like screen time.
