What is the three-layer clothing system for winter?

The three-layer system consists of: 1) Base Layer (moisture-wicking), 2) Insulating Layer (traps heat), and 3) Outer Layer (blocks wind and moisture). This system allows you to add or remove layers as needed for optimal temperature regulation.

Why are older adults more susceptible to cold stress?

Older adults are more vulnerable due to decreased metabolic rate, reduced subcutaneous fat, impaired vasoconstriction response, slower shivering thermogenesis, and diminished sensation of cold. Medications and chronic conditions can further affect thermoregulation.

What are the early signs of hypothermia?

Early signs include shivering, cold pale skin, and slurred speech. Danger signs include confusion, drowsiness, and loss of coordination. Hypothermia can occur even above freezing temperatures and requires immediate warming and medical attention.

How does wind chill affect body temperature?

Wind chill makes temperatures feel colder than they actually are by blowing away the warm air layer around your body. For example, 32°F (0°C) with 20mph wind feels like 21°F (-6°C). Wind increases heat loss through convection and raises frostbite risk.
