Understanding Dehydration: How To Prevent It

As summer temperatures rise, so does the risk of dehydration. Lack of hydration is especially dangerous to children, the elderly, and outdoor workers.

Summer in the high desert is no joke. Hot days, dry air and wind pull water from the body faster than many people realize. Dehydration can sneak up on anyone, but some people are at higher risk, and some medicines can make it more likely.

What dehydration is

Dehydration happens when your body loses more fluid than it takes in. Water helps control your temperature, protect your joints and keep your organs working. When levels drop, your body struggles to keep up.

Know the warning signs

Early signs can be easy to brush off. Watch for:

• Thirst and a dry or sticky mouth.
• Dark yellow urine, or urinating less than usual.
• Headache, tiredness or dizziness.
• Muscle cramps.
• In babies, fewer wet diapers and no tears when crying.

Confusion, a racing heartbeat, fainting, or not urinating at all are signs of serious dehydration. Call 911 or get to emergency care right away.

Who is at higher risk

Young children, older adults and people who work outside are most at risk. Older adults may not feel thirsty even when they need fluids. People with diabetes, kidney disease or heart conditions should be especially careful.

Certain medicines also play a role. Water pills, some blood pressure medicines, and some medicines for mood or allergies can affect how your body handles fluid and heat. Do not stop any medicine, but do ask us whether yours needs extra attention in hot weather.

If you are thirsty, your body is already asking for help. Drink before you feel it.

Simple ways to stay hydrated

Keep a refillable water bottle with you and sip through the day. Eat water rich foods like watermelon, cucumbers and oranges. Limit sugary drinks and alcohol. Plan outdoor work or play for early morning or evening. Wear light, loose clothing and take breaks in the shade.

If you have been told to limit fluids because of a health condition, follow your doctor's guidance and ask how to stay safe in the heat. Our pharmacists can also help you choose an oral rehydration product if you have been sick or sweating heavily.

Check on neighbors and relatives during heat waves, especially older adults who live alone. A quick call or visit to make sure they have water, a cool place to rest, and their medicines can make a real difference. If someone you know relies on home delivery for prescriptions, remember that CarePoint offers free delivery anywhere in California, so no one has to wait in the heat.
