Welcome to Iowa in August! It’s hot! This time of year, we always go to the Iowa State Fair.
It is easy to over-do it on treats, but I can never resist sharing some funnel cake and lemonade with my family. It can get really hot walking around in the sun. I always make sure we have plenty of sunscreen and water. The recommendation is to drink close to 12 cups of water per day for women and 16 for men. When eating a balanced diet, 20% of you water comes from your food. This means women should drink 9 cups per day and men should drink 12. You need to drink more water when you’re doing activities outside in hot temperatures- such as walking around the Iowa State Fair. You should also try to drink extra in the winter (when there is less moisture in the air), during illness and during exercise.
Try to drink water every 15-20 min when exercising, don’t wait until you are thirsty! When you are thirsty, your body is already dehydrated. If working really hard or doing exercise lasting more than a couple hours, sports drinks could be helpful to replace water and electrolytes. If you are just doing moderate exercise, sports drinks are not necessary.
Other beverages count toward your daily requirement as well. If not drinking water, drink unsweetened drinks such as 100% fruit juice and milk. Coffee and unsweetened tea count too, though caffeine is mildly dehydrating and should be enjoyed in moderation. Best bet is to stick to water as much as possible. It is a good habit to carry a water bottle when you’re on the go and drink a glass with every meal.
