Many warning signs of summer illnesses actually start in the mouth. Though no two patients experience the same constellation of symptoms, many initially report problems with thirst, dry mouth and dry tongue before the onset of more worrisome indicators.
The most important thing you can do to prevent summer heat illnesses is drink plenty of fluids. This is especially true if one has been outdoors working or playing in the sun. Establish a schedule and drink plenty of fluids at regular intervals. You should also be drinking even if you do not feel thirsty or dehydrated. For an extra push, drink solutions like Pedialyte or Gatorade. These help maintain electrolyte balance during extreme heat. Avoid alcohol consumption, as liquor often dehydrates the body and leaves it wanting of critical fluids.
