windrespiratory

Windrespiratory is a term used in environmental physiology and ecophysiology to describe the interactions between wind and respiratory processes across organisms and environments. The concept encompasses how wind speed, direction, and turbulence affect gas exchange, moisture exchange, particle transport, and thermal regulation during respiratory activity.

In animals and humans, wind influences the conditioning of inhaled air by the upper airways, with higher wind speeds increasing convective heat and moisture loss from the respiratory tract. Outdoor wind can alter perceived comfort and exercise performance, and may change exposure to airborne particles and pathogens, affecting inhalation risk and respiratory irritation.

In plants, wind modulation of the boundary layer around leaves affects stomatal conductance and transpiration. Moderate wind tends to reduce boundary layer resistance, promoting CO2 uptake and cooling, while very strong wind can cause desiccation and mechanical stress that closes stomata or reduces photosynthetic rate.

Researchers study windrespiratory effects using field measurements, wind tunnels, computational fluid dynamics, and respirometry. Applications include improving athletic training in outdoor conditions, occupational health for workers in windy environments, air quality assessment, urban design, and understanding plant ecophysiology in windy habitats.
