- Fitness for work is affected by persons not frequently rehydrating in hot work environments and climates. A low rehydration replenishment rate would be 4 – 6 litres per day with hotter climates and excessive work demands requiring a higher rate. It is essential that workers being placed to work in remote or isolated locations must have adequate water to rehydrate for the duration of their task.
- The most effective rehydration fluid is water. Isotonic drinks, soft drinks, cordials and fruit juices do not offer rehydration as effective as water. To assist in the reduction of dehydration, supplementary controls such as brimmed hats, long sleeved shirts, the provision of shade, rest regimes, neck coolers and ventilation should be provided at the work site.
Symptoms / signs of dehydration may involve the following
- Headache
- Dizziness
- Nausea / Vomiting
- Fainting
- Dark urinary discharge
If you experience these, seek immediate rehydration, report it to your supervisor and rest. If required, a first aider should refer you to professional treatment.
