g.‚ conduction‚ convection‚ radiation and evaporation) exceeds heat production (e.g.‚ chemical thermogenesis). Hypothermia/cold stress is due to a disturbance in the net regulation of heat production and heat loss that can result from defective homeostatic regulation‚ reduced metabolism (e.g.‚ diminished cellular metabolism) or increased loss from exposure to extreme cold. (31) Exposure to cold stimulates the hypothalamus through afferent fibers of cold receptors and via cold circulating blood. Hypothalamic

In asthma‚ the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma is either extrinsic
