How does Dr. Biplab Das explain the link between sleep and vitamin C?

Dr. Das explains that sleep deprivation increases oxidative stress, leading to faster depletion of vitamin C reserves.

What is the impact of poor sleep on magnesium levels?

Poor sleep increases urinary magnesium loss and reduces intestinal absorption, potentially lowering levels by 10-20%.

Why is sleep essential for iron absorption according to Dr. Das?

Sleep deprivation raises inflammatory markers, increasing hepcidin and reducing iron absorption by 15-30%.

Sleep Loss Harms Nutrient Absorption

Summary

Inadequate sleep impairs micronutrient absorption, weakening immunity.
Poor sleep disrupts gut function, reducing nutrient uptake efficiency.
Chronic sleep deprivation can lead to deficiencies in vital vitamins.

Chronic sleep deprivation is increasingly recognized for its detrimental effects beyond simple fatigue. Emerging research highlights that inadequate sleep profoundly interferes with the body's absorption and utilization of vital micronutrients. This silent disruption weakens immune responses, impairs cognitive functions, and disrupts metabolic processes.

The connection between sleep and gut health is critical, as the gastrointestinal tract's rhythm aligns with sleep-wake cycles. Poor sleep alters gut motility and microbiome balance, directly reducing the efficient absorption of vitamins and minerals. This means even a balanced diet may not provide adequate nutrition if sleep is compromised.

Deficiencies in key micronutrients such as Vitamin C, calcium, magnesium, iron, and B-complex vitamins can arise from insufficient sleep. These deficiencies can lead to serious health issues including weakened immunity, bone problems, neurological disturbances, and anemia. Prioritizing 7-9 hours of quality sleep is therefore essential for maintaining health and optimal bodily functions.
