[Grounds of the duration of work shift for female vegetable growers working in the field in the summer].

Analysis of changes in heat state of female vegetable-growers within the shift helped to determine correlation between microclimate parameters (including general indicator of extrinsic heat load--WBGT index) and temperature state in the females adjusted and non-adjusted to heat. Depending on various relationships between the microclimate parameters inducing variable overheating, duration of the working shift is set for stably optimal heat state.
