Got Water?

Keep in mind as you enjoy the hot summer months that higher temperatures combined with outdoor activity can lead to dehydration. Knowing how to prevent dehydration and treat it in its early stages is the key to avoiding serious health consequences.

What is Dehydration?
Dehydration occurs when your body loses too much water. Your body reacts to fluid loss by redirecting blood flow to your two most important organs: your brain and heart. That means there’s less blood flow to other parts of your body and, after a while, you may start to feel the effects. The symptoms of mild or moderate dehydration often include:

• Thirst


• Dry, sticky mouth


• Sleepiness


• Decreased urine output


• Headache


• Few or no tears when crying


• Muscle weakness


• Dizziness or lightheadedness


• Decreased sweating


• Irritability

More severe dehydration can lead to serious symptoms such as anxiety and agitation, parched skin, or rapid heartbeat, and requires emergency treatment.

Who’s Most at Risk?
Any one can become dehydrated, but certain people are at greater risk. Infants and children can more easily become dehydrated due to their high metabolic rate and low body mass. Older adults are often more susceptible since their bodies are less able to conserve water and they tend to lose “thirst sense” as they age. People with chronic illnesses (such as diabetes) may become dehydrated due to disease symptoms, medications, or lack of appetite. In addition, endurance athletes and people living or working at high altitudes are at greater risk.

Medication Complications
Planning to take a cruise, go on a camping trip, or simply spend a lot more time outside than usual? If you take certain medications that can cause dehydration (or make it worse), you may need to adjust your dosage or alter your hydration strategy. Medications that can cause dehydration include:

• Antihistamines (e.g., Benadryl)


• Chemotherapy drugs (e.g., Cytoxan)


• Diuretics (e.g., Lasix)


• Laxatives (e.g., Correctol)


• Heart and blood pressure medicines (e.g., Digoxin)


• Psychiatric drugs (e.g., Seroquel)

Even over-the-counter drugs like Aspirin and Ibuprofen can affect your body fluid balance. If you take one of these types of drugs, contact your doctor before your next big outdoor excursion. He or she can tell you what you need to do to prevent dehydration.

Hydration Strategy

Everyday Prevention: Follow these tips to stay healthy and hydrated.

For everyone:

• Drink water every 15-20 minutes during exercise, and after.


• Avoid caffeine (it can accelerate dehydration).


• Eat fruits and vegetables, and consider taking a multivitamin to replace
  depleted vitamins and minerals .


• Wear light-weight, light-colored clothing outdoors.

For adults:

• Drink 8 to 10 cups of water each day.


• Pack a sports drink containing electrolytes (like salt and calcium) if you’ll
  be exercising longer than 60 minutes.


• Avoid alcohol (it can accelerate dehydration).


• On a high-protein diet? Drink more water.
  

For kids:

• Drink 4 to 10 cups of water each day (depending on age).


• Choose water or a kid’s oral rehydration solution (ORS) like Pedialyte.


• Avoid sports drinks, soda, and juice (these contain a lot of sugar, which can aggravate dehydration).


• For babies under 1 year, breast or bottle-feed often.

At-Home Dehydration Treatment
If you catch it early, you can often treat mild or moderate dehydration at home. If you notice symptoms of dehydration:

For everyone:

• Stop your activity and rest. Get out of sunlight and lie down in a cool spot indoors or in the shade.


• Prop up your feet.


• Remove excess clothing.

For adults and kids 12+:

• Drink water, juice, or a sports drink. Consume 8 cups of cool liquid over the next 2 to 4 hours.


• Rest and continue to drink lots of fluids for the next 24 hours.
  

For kids 1-11:

• Drink a kid’s ORS, half-strength orange juice, or plain water (if also eating food).
  

For babies under 1 year:

• Feed them an ORS via bottle, spoon, or dropper if dehydration develops.
