Braving the Freeze: Protecting Your Body Against Extreme Cold

The video explores how cold weather affects the body, focusing on why lips crack, hands dry out, and extremities go numb. It explains the unique skin structure of lips, the lack of sebaceous glands, and the impact of cold air on hydration. For hands, frequent washing and thin skin contribute to dryness. Numbness in fingers and toes is due to vasoconstriction, a process where blood flow is reduced to maintain core body temperature. Hormonal differences also affect cold sensitivity, particularly in women. The video suggests protective measures like using greasy substances and layering clothing.
