As we head into the peak summer months, temperatures rise, and with them comes an increased risk of heat exposure. Heat stress, also known as hyperthermia, results in numerous deaths every year, according to the Centers for Disease Control. It can also lead to exhaustion and heat strokes in extreme cases, with cramps, rashes, and burns possible as well.
Managing hydration, electrolyte levels, and medication considerations is key to navigating the next few months safely. Whether for yourself or your family, it’s worth taking some time to ensure you have all the knowledge and supplies you need.

Hydration, Electrolytes, and Medical Considerations for Heat Safety
Approaching heat safety from multiple angles helps ensure you stay protected and healthy all season long. The three key metrics we recommend keeping in mind are hydration, electrolytes, and medical considerations, as managing these well significantly increases your level of safety.
Hydration
- The general daily recommendation is around 8 8-ounce glasses of water, but heat and activity can significantly increase that need.
- Thirst is a late indicator of dehydration. Drink proactively throughout the day rather than waiting until you feel parched.
- During outdoor activity, aim for an additional 1.5 to 2.5 cups of water per hour to replace what you’re losing.
- Caffeinated and alcoholic beverages can accelerate fluid loss, so balance them with extra water intake on hot days.
Electrolytes
- Sodium, potassium, and magnesium help your body retain fluids and keep muscles functioning properly, which is especially important in the heat.
- On a normal day, a balanced diet naturally replenishes electrolytes, but heavy sweating quickly changes the equation.
- After strenuous activity or prolonged heat exposure, sports drinks, electrolyte powders, or coconut water can quickly restore balance.
- Look for electrolyte options low in added sugar to get the benefit without unnecessary calories.
Medication & Supplement Considerations
- Certain medications, including diuretics, antihistamines, blood pressure medications, and some antidepressants, can increase heat sensitivity and fluid loss.
- If you or a family member takes any of these regularly, monitoring hydration and limiting prolonged exposure to heat are especially important.
- Magnesium is commonly depleted through heavy sweating and supports muscle function and recovery.
- Vitamin C has antioxidant properties that help protect skin during increased sun exposure.
- When in doubt about what supplements are right for you, ask a pharmacist to review your current medications and make safe, personalized recommendations.
Keeping your body fueled and hydrated is essential, but what’s happening around you matters as much. A few key environmental metrics can help you stay one step ahead of the heat.
Other Heat Safety Metrics to Monitor
Hydration is just one piece of the heat safety puzzle. Keeping an eye on a few additional factors can make a meaningful difference in how your body holds up through the summer.
- UV Index: Check the daily UV index before heading outside. A rating of 3 or above warrants sunscreen (SPF 30 or higher), protective clothing, and sunglasses. At 8 and above, limit direct exposure during peak hours (10 am-4 pm).
- Heat Index: This is the “feels like” temperature that accounts for humidity. A 95°F day with high humidity can feel like 110°F, dramatically increasing the body’s strain. Check the heat index alongside the actual temperature forecast.
- Air Quality: Poor air quality compounds heat stress, especially for those with asthma or respiratory conditions. On high-heat days, check your local AQI (Air Quality Index) before planning outdoor activities.
- Warning Signs: Recognize early symptoms of heat exhaustion: heavy sweating, weakness, dizziness, nausea, and headache. These are your body’s signals to get indoors, cool down, and rehydrate immediately.
With the right information and a little preparation, navigating even the hottest days of the year becomes more manageable.
Stay Safe and Cool All Summer Long
Summer has the longest days, which can easily be filled with all kinds of fun outdoor activities, meaning significant time in the sun. Don’t overlook heat safety before making a plan, as when you take the right steps to prepare, you give your body what it needs to stay healthy and function without harm.
Stock up on electrolytes, check your medications for heat-related risks, and know your numbers for UV and the heat index. A little preparation goes a long way toward staying safe and well hydrated all summer long.
