Winter Dehydration

Category: Toolbox Talks
Dehydration is usually associated with work being conducted in the warmer summer months. However, workers have an elevated risk of dehydration in cold weather because the body’s thirst response is diminished. This can easily be overlooked if we are not looking for the signs and symptoms of dehydration.

Cold weather dehydration can lead to:
• Reduced work performance
• Reduced Blood Volume
• Increased Heart rate
• Reduced skin & muscle blood flow
• Impaired thermo-regulation (sweating)
• Headache, nausea, insomnia, dry mouth

Workers can be protected from the dangers associated with working in cold
environments and dehydration by doing the following:
• Train workers how to recognize symptoms and how to respond appropriately when working in cold weather
• Dress in layers to absorb perspiration
• Check the color of your urine
• Eating fruits and vegetables with a high water content
• Drink one cup of water every fifteen to twenty minutes/ warm or at room temperature to keep your body temperature optimal
• Water and sports drinks are the best fluids to maintain hydration
• Keep plenty of water in the job trailer or connex on the job site
• In severe cases follow your site protocol to get medical assistance
