HEAT SAFETY AWARENESS

As we all know, this summer is already warming up pretty quickly, and the first official day of summer isn’t until June 20th!  OSHA is partnering with the National Oceanic and Atmospheric Administration (NOAA) on weather service alerts to incorporate worker safety precautions when heat alerts are issued across the United States.  NOAA is including pertinent worker safety information on its Heat Watch Web page.   

 Because conditions are extremely hot with high humidity this season, companies would be wise to follow all advisories to keep their employees as safe as possible during this trying time. 

Which brings up the question, how much water should we drink?  Water is the body’s principle chemical component and makes up about 60 per cent of your body weight.  Your entire body’s system depends on water.  Lack of water can lead to dehydration, a condition that occurs when you don’t have enough water in your body to carry out normal functions.  You can become tired and suffer energy loss with even mild dehydration.   We’ve all been told to consume six to eight glasses of water per day.  Dr. Margaret McCartney, a Scottish physician, states that there is no quality scientific evidence to support this recommendation, which she says can lead to over-hydration in some individuals.  This eight-glass formula doesn’t fit everyone.  The more active a person is, the more they will need to replace fluids.  Larger people, pregnant and nursing women, and those who take dehydrating medications will likely need to add more water to their diet.  

The Mayo Clinic staff suggests that your water needs depend on many factors, such as your health, how active you are, and where you live.  Because water is essential to good health, needs vary by individual.  If you use thirst as a guide for when to drink, by the time you are thirsty, you may already be slightly dehydrated.  As you get older, your body is less able to sense dehydration and send your brain signals of thirst.  Here are some tips to ward off dehydration, and make sure your body has the fluids it needs:

  • Drink a glass of water with each meal and between each meal;
  • Hydrate before, during and after exercise;
  • Substitute sparkling water for alcoholic drinks at social events. 

Many outside workers are exercising in temperatures that are very hot,  causing them to sweat more.  These folks will need to increase their water intake.  Oral hydration solutions, such as Powdered Gatorade Mix, Powerade or CeraLyte may help those who are in situations that cause them to sweat heavily.  Some experts recommend that bodies only need a minimal amount to keep the body in balance and give that energy kick.  Sometimes simply taking sips or swishing a sports drink will do the trick. 

At home, select foods that keep you hydrated and healthy.  Strawberries, cantaloupes, watermelon, and peaches are packed full of water and potassium, which is the electrolyte lost when your body sweats.  This is a great way to balance fluids that your body needs, and regulate your heartbeat and circulation.  Plus – they are delicious!  

Rest, shade and water are very important for your employees.  Individuals know what their body needs, and they must be diligent about taking the time to stop for a drink of water throughout the day. You can find more information on the OSHA website, as well as NOAA’s  website.  Try to stay cool, take breaks during the day, and stay hydrated! 

Last, but not least, wear a hat, sunscreen, long-sleeve shirts if possible, and safety sunglasses that offer UVA and UVB protection for your eyes.  It’s going to be a long, hot summer, so take all the precautions you can to avoid heat-related illness.

WATER KEEPS YOU RUNNING IN THE SUMMER HEAT!

August days are sweltering in Texas, as well as many other parts of the country.  There are many athletes – baseball players, football players, and runners that are exposed to the heat during the hottest time of the day, in many cases.  There are some keys to staying healthy while exercising, whether as an athlete, or worker who is exposed to the elements every day,  becoming dehydrated.

Mild dehydration is the loss of no more than 5% of the body’s fluid. Loss of 5-10% is considered moderate dehydration. Severe dehydration (loss of 10-15% of body fluids) is a life-threatening condition that requires immediate medical care. 

One of the first steps to getting used to the heat is to become acclimatized.  As the weather heats up, you must ratchet down your outdoor workout for at least five days to two weeks, in order to build up heat tolerance.  If you ride a bike, ride it a little slower until you get used to hotter temperatures.  Walk instead of running, if you are a jogger.  If you are involved in an intense workout, you are creating more heat for your body.  

A sweat rate test will tell you how much fluid you need to replace from your workout: weigh yourself without clothes before and after a workout; add the amount of any fluid you drank from your weight-loss difference, and you’ll have the amount of fluid you lost through sweat.  Hydration keeps your body from overheating.  The best policy is to know what works best for each individual.  The American College of Sports medicine suggests that too much water can cause a sodium imbalance in the body.  Listen to your thirst.  Some fitness program coaches recommend athletes drink 16 to 20 ounces of water before training, carry 20 ounces of water to sip during the workout, and change to an electrolyte sports drink such as Gatorade after the first hour.  Lost sodium can also be replaced with salty snacks.  

There is a common belief that caffeinated drinks dehydrate you, but according to cardiologist Benjamin Levine, caffeinated drinks such as coffee and tea will help hydrate your body throughout the day, because they contain water. Dr. John Carlo, Medical Director of Dallas County Health and Human Services recommends that drinking more fluids the day before strenuous exercise will help prevent dehydration.  Hydrating at night is also a good idea, says Dr. Carlo. 

If you have health problems or are more susceptible to heat, you may want to exercise in an air-conditioned wellness center, or gym.  They contain all types of equipment that will enable you to get the amount of conditioning you want.  

Even when the weather is just a few degrees higher than normal, it can take its toll on our bodies.  Those who work outdoors should always take the proper precautions and be able to take breaks away from the sun as often as possible.  Always have fresh water available, and drink it often.  We all need to keep our cool anyway we can!
