Cold Waves: Unmasking Hidden Dangers to Immunity, Hydration & Overall Health

• Cold waves weaken immunity by constricting respiratory blood vessels, hindering immune cell movement, and dry air aids virus spread.
• Shorter daylight hours in winter reduce Vitamin D levels, crucial for immune regulation, increasing infection risk.
• Dehydration is a hidden winter risk; cold suppresses thirst, leading to reduced fluid intake despite ongoing fluid loss.
• Inadequate hydration thickens respiratory secretions, impairs circulation, digestion, kidney function, and slows recovery.
• Common myths like layering being sufficient or cold killing germs increase vulnerability to health risks.

Why It Matters: Cold waves pose hidden health risks to immunity and hydration, requiring awareness and preventive measures.
