ANATOMY

Detailed explanation-1: -Respiratory infections can be caused by cold air through increased bronchial inflammation caused by association of trigger factors such as cold and infections are both able to destabilize the patient.

Detailed explanation-2: -Cold weather, and particularly cold air, can also play havoc with your lungs and health. Cold air is often dry air, and for many, especially those with chronic lung disease, that can spell trouble. Dry air can irritate the airways of people with lung diseases.

Detailed explanation-3: -Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature. A body temperature that is too low affects the brain, making the victim unable to think clearly or move well.

Detailed explanation-4: -Toes, fingers, ears and nose are at greatest risk because these areas do not have major muscles to produce heat. The body preserves heat by keeping the internal organs warm; thus, reducing the flow of blood to the extremities under cold conditions.

Detailed explanation-5: -An increase in mucus production (a runny nose). Swelling of the lining of the nose (making it hard to breath and congestion). Sneezing (from the irritation in the nose). Cough (from the increased mucus dripping down the throat).
