Temperature Extremes
A change in body temperature due to extreme workplace conditions can lead to heat- or cold-related illness. If not treated in time, both heat and cold stress can develop into life-threatening situations.
- Heavy work in high temperatures can cause muscle cramps, dehydration, sudden collapse, and unconsciousness.
- Cold temperatures can lead to fatigue, irregular breathing, confusion, and loss of consciousness (hypothermia).
