Understanding Why We Feel Cold and How Our Bodies Respond

Experts explain the science behind shivering, goosebumps, and effective ways to stay warm during winter.

The human body maintains a core temperature of around 37°C, with the skin and extremities allowed to be cooler to preserve vital organ function.
Cold triggers the body's defense mechanisms, including reduced blood flow to extremities, shivering to generate heat, and activation of brown fat for additional warmth.
Key cold-sensitive areas, such as the abdomen, have high concentrations of temperature sensors that signal the brain to initiate these responses.
Effective ways to stay warm include wearing insulating clothing, staying active, and avoiding alcohol, which can cause faster heat loss despite the sensation of warmth.
Prolonged exposure to extreme cold can lead to dangerous hypothermia, with confusion and unconsciousness as warning signs requiring immediate medical attention.
