How does height affect peak flow?

Height can influence peak flow by affecting lung capacity and respiratory function. Taller individuals may have larger lung volumes, which can lead to greater airflow and higher peak expiratory flow rates. However, factors such as age, fitness level, and underlying health conditions also play significant roles in determining an individual's peak flow, making height just one of several contributing factors. Consequently, while there may be a correlation, it is not solely dependent on height.
