Farmer's lung occurs because repeated exposure to antigens, found in the mold spores of hay, crops, and animal feed, triggers an allergic reaction within the farmer's immune system. [5] The defense mechanisms of the body present as cold and flu-like symptoms that occur in individuals who experience either acute or chronic reactions.
Tropical plants may begin to experience cold damage when the temperature is 42 to 48 °F (5 to 9 °C), symptoms include wilting of the top of the stems and/or leaves, and blackening or softening of the plant tissue. Frost or cold damage can be avoided by ensuring that tender plants are properly hardened before planting, and that they are not ...
Cold weather can make it harder for patients to breathe. [24] Whether high altitude helps or worsens asthma is debatable and may vary from person to person. [25] Obesity and the systemic inflammation of obesity has been shown to worsen lung function and increase the risk of developing asthma exacerbations. [26]
Eczema, otolaryngeal symptoms of hay fever or asthma will often dominate leading to the food allergy being unsuspected. Often well-cooked, canned, pasteurized, or frozen food offenders cause little to no reaction due to denaturation of the cross-reacting proteins, [ 9 ] causing delay and confusion in diagnosis as the symptoms are elicited only ...
Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.

Thunderstorm asthma (also referred to in the media as thunder fever or a pollen bomb [1]) is the triggering of an asthma attack by environmental conditions directly caused by a local thunderstorm. Due to the acute nature of the onset and wide exposure of local populations to the same triggering conditions, severe epidemic thunderstorm asthma ...
Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C.
As a result, inflammation and associated healing process leads to scar formation and tissue remodelling, which are symptoms that can be found in almost all asthmatics patients. Thus, asthma is a chronic inflammatory disorder of the airways. Asthma is divided into two subgroups: atopic (extrinsic) and non-atopic (intrinsic).
