As temperatures climb during the summer months, staying cool and properly hydrated becomes more than a comfort—it becomes a health necessity. Hot weather can pose serious risks, especially if you’re on certain medications or have underlying health conditions. Dehydration and heat-related illnesses like heat exhaustion and heatstroke can develop quickly and lead to serious complications if not addressed promptly.
At Olympia Plaza Pharmacy, we care about helping you stay healthy all year long. In this article, we’ll explore the warning signs of dehydration, how your prescription medications might increase your risk, and simple, pharmacist-approved tips for staying hydrated and safe in the summer heat.
Your body relies on water to regulate temperature, support organ function, and keep energy levels steady. When you’re exposed to high heat, you sweat more to cool off—losing fluids and essential electrolytes in the process. If you’re not replacing those fluids, you can quickly become dehydrated.
Dehydration symptoms can sneak up on you, and they’re often mistaken for just feeling tired or run down. Left unchecked, dehydration can lead to heat exhaustion or even heatstroke, which can be life-threatening without medical intervention.
Recognizing the early warning signs of dehydration and heat-related illness can help you take action before things get serious. Here’s what to watch for:
Dry mouth or a sticky feeling in your mouth
Headaches, dizziness, or lightheadedness
Fatigue, sluggishness, or feeling weak
Muscle cramps or a flushed, overheated sensation
Dark yellow urine or decreased urination frequency
Rapid pulse or shallow breathing
Nausea, vomiting, or upset stomach
Cold, clammy skin—even in hot weather
Mental confusion or difficulty concentrating
Fainting or passing out
Pro Tip: If you’re feeling very thirsty, you’re likely already dehydrated. It’s better to hydrate consistently throughout the day, rather than waiting until you feel thirsty.
Many people don’t realize that common prescription or over-the-counter medications can make them more vulnerable to dehydration or overheating. Some medications may cause increased urination, suppress sweating, or affect your body’s natural temperature regulation.
Diuretics (“water pills”) – Often prescribed for high blood pressure or heart failure, these increase urine output and fluid loss.
Antihistamines – Used for allergies or cold symptoms, they can cause dry mouth and reduce your ability to sweat.
Antidepressants or Antipsychotics – Some can interfere with your body’s temperature regulation or increase fatigue in the heat.
Diabetes Medications – Dehydration can lead to dangerous blood sugar fluctuations, especially if you’re active or skipping meals.
Laxatives – Overuse can cause excessive fluid loss, especially when combined with heat exposure.
If you’re currently taking any of these medications—or a combination—talk to your pharmacist about your heat and hydration risks.
Fortunately, preventing dehydration and heat exhaustion doesn’t have to be complicated. With a few mindful habits, you can enjoy summer activities while protecting your health.
Keep a reusable water bottle with you and take small sips throughout the day. Set phone reminders or use hydration tracking apps to stay on schedule.
Incorporate fruits and vegetables with high water content into your meals. Great options include:
Watermelon
Cucumber
Strawberries
Oranges
Celery
These foods also provide natural electrolytes to help replenish what you lose through sweat.
Both caffeine and alcohol can contribute to dehydration. If you do consume them, be sure to increase your water intake to compensate.
Wear loose-fitting, breathable clothing in light colors. Avoid dark, heavy fabrics that trap heat. A wide-brimmed hat and sunglasses can also provide extra protection.
If you’re outdoors for extended periods, give your body regular rest breaks in shaded or air-conditioned spaces. Even short breaks can help regulate your core temperature.
If you’re sweating a lot or engaging in intense physical activity, electrolyte supplements can help replace lost minerals. Ask your pharmacist about safe, low-sodium options tailored to your health needs.
