September Safety Message: Stay Hydrated
One of the first signs of being dehydrated, is your thirst. Your brain gets a signal that it's thirsty, after being about 1% below your body weight. With mild dehydration starting just after your body loses 1.0-1.5% of its body weight. Here are some signs and symptoms to look out for when your body is at a mild level of dehydration. They include headache, exhaustion, rapid HR, muscle cramps, dry mouth and irritability.
Pleases make special note that on working fires, firefighters should anticipate losing 50-70 oz of sweat in just 30-45 minutes of fireground activities. To put that in perspective, under normal circumstances the body will only lose 35-90 oz of water a day through sweat, breathing and body waste. Which makes you lose sweat 5X faster than athletes in working conditions with gear on. This level of sweating this could push you into a severe level of dehydration which can really put a strain on your cardiovascular function.
The best solution to staying hydrated is to just drink water throughout the day, every day.
