Cold

Definition

Cold refers to a reduction in body temperature or exposure to low environmental temperatures. It can increase metabolic demands and impact pulmonary function, requiring tailored nutritional strategies for optimal wellness.

5 Must Know Facts For Your Next Test

1. Cold environments can increase the body's caloric needs as it works harder to maintain core temperature.
2. Adequate intake of antioxidants is crucial in cold conditions to support immune function and reduce oxidative stress on the lungs.
3. High-protein diets can help maintain muscle mass and respiratory strength during cold exposure.
4. Hydration remains critical in cold weather as dry air can dehydrate mucous membranes, affecting lung health.
5. Cold-induced thermogenesis necessitates additional micronutrients such as Vitamin C and zinc to support metabolic processes.

Review Questions

• How does cold exposure affect the body's caloric needs?
• Why is antioxidant intake important for pulmonary wellness in cold conditions?
• What role does hydration play in maintaining lung health during exposure to cold?

Thermogenesis: The process of heat production in organisms, typically increased in response to cold environments.

Oxidative Stress: An imbalance between free radicals and antioxidants in the body, which can be exacerbated by cold weather.

Micronutrients: Vitamins and minerals required by the body in small amounts for proper metabolic functions, especially important during increased metabolic demands like those caused by cold exposure.
