Rising temperatures and higher humidity levels raise health concerns about heat illness for all Iowans, especially those doing flood preparation work. “The strenuous work of flood preparation is challenging, even for young and healthy individuals,” said Iowa Department of Public Health (IDPH) Director Dr. Mariannette Miller-Meeks. “Whether doing flood prep work in western Iowa, or simply doing yard work in other parts of the state, make sure you take time to refresh, re-hydrate and rest.” One of the most important ways to protect against heat illness is to replace fluids and minerals lost through sweating:
Drink plenty of non-alcoholic, sugar-free fluids like water. If possible, avoid caffeinated and carbonated beverages.
Don’t wait until you are thirsty to drink water. If you feel thirsty, you are already low on fluids.
When temperatures are high, drinking two to four 8-ounce glasses of cool fluid an hour will help you keep hydrated.
Salt and minerals lost through sweating can be replaced with re-hydration fluids like sports beverages designed for athletes and Pedialyte for young children. Salt can also be replaced with foods like salted crackers, and minerals like potassium can be replaced by eating fruits, especially bananas.
In addition, take steps to avoid over-heating:
Work during the cooler times of day and wear appropriate, loose, light-weight clothing.
If working outdoors, wear sunscreen, large brimmed hats and stay in the shade as much as possible.
Ventilation and air movement will help reduce heat-related illness. Use fans and air conditioning whenever possible. Take cool showers to help cool off.
Pace yourself. Start slowly and pick up intensity gradually. If exertion makes your heart pound and leaves you gasping for breath, STOP the activity.
Take frequent breaks, at least 5 minutes each hour, to drink cool fluids and rest in a shady or air conditioned area.
Watch the condition of co-workers or those around you. Heat-induced illness can cause a person to become confused or even lose consciousness. A decrease in urination or dark- colored urine, a dry mouth and throat, and feeling dizzy when standing up are all symptoms of dehydration and potential heat illness. If you or those around you experience any of these symptoms, stop immediately and take time to re-hydrate and rest.
