Abstract

The aims of this study were to explore the effect of (I) a 2 % CO2 atmosphere, and (II) of a night-work shift every other day, on the following circadian rhythms: oral temperature, peak expiratory flow, grip strength, arterial blood pressure, speed and urinary pH, volume and potassium excretion.
