As Temps Soar, Be Heat Aware

Summertime is fun time, but it can also be a dangerous time.
Topping the list of summertime hazards are extreme heat and drowning. As the heat blankets Tennessee this week, let’s talk about how to prevent heat related illnesses.
Extreme heat is the number one weather-related killer in the U.S. and overexposure can be especially dangerous for children, seniors, those with preexisting illnesses and patients on certain types of prescriptions and over-the-counter medicines. There are three major types of heat-related health conditions you should be familiar with:
- Heat cramps typically occur in the stomach, arms and legs, and are the result of losing too much water and salt. They’re often the first sign of a heat-related illness and can lead to more serious conditions like heat exhaustion and heat stroke.
- Heat exhaustion occurs when your body loses too much water and salt, and can’t cool itself. It typically presents as a combination of many symptoms, including headache, nausea, dizziness, weakness, irritability, thirst, heavy sweating, elevated body temperatures, decreased urine output and skin that appears cool, moist, pale, ashen or flushed. If left untreated, heat exhaustion can lead to heat stroke.
- Heat stroke is a medical emergency that occurs when the body has lost excessive amounts of water and salt, and is completely overwhelmed by heat. Characterized by dizziness, fainting, loss of consciousness, slurred speech, confusion, agitation, hallucinations and an altered mental state, a heat stroke requires immediate medical attention, as it can lead to organ failure and death. Placing ice packs in the patient’s armpits and groin area can help with cooling while being transported to medical care.
Here are a few simple ways you can beat the heat this summer and help prevent heat-related illnesses:
- Be aware of temperature and humidity levels in your area and avoid going outdoors for activities or exercise in extreme heat.
- Stay hydrated by drinking plenty of water, regardless of how active you are (and remember to keep your pets hydrated too!). Sports drinks can also be helpful to replace salts and provide some sugar.
- Always use an SPF-15 or higher sunscreen that protects against both UV-A and UV-B rays, applying 30 minutes prior to exposure and reapplying accordingly.
- NEVER leave infants, children or animals in cars unattended, even if the windows are cracked open.
- Take frequent breaks when enjoying the outdoors, especially if you are not accustomed to working or exercising in a hot environment.
- Break out your favorite lightweight, light-colored and loose-fitting clothing.
- Take advantage of cooler areas (even when outside), and when the temperature rises above 90 degrees, consider switching to an indoor activity.
- Limit or avoid alcoholic beverages, as they can impair your body’s ability to self-regulate its temperature and compromise your hydration status.
- Stay mindful of the signs and symptoms of heat-related illnesses and know how to respond.
Nothing feels better than a dip in the water in summer, but it’s important to keep your safety in mind at all times. Every year in the U.S. there is an estimated average of 11 drowning deaths per day and an estimated average of 22 non-fatal drownings per day.
Drowning can happen in seconds and is often silent. And even non-fatal drowning can result in very serious injuries, permanent disabilities and long-term health problems.
Be it poolside, lakeside or beachside, the tips listed below are key to ensuring a fun, safe summer for all:
- Only swim in designated areas supervised by lifeguards.
- Always swim with a buddy, especially if you have a seizure disorder or other medical condition that increases your risk of drowning.
- Never dive in the shallow end of a pool.
- Designate a responsible adult to supervise children closely and constantly when they are in or near water (including bathtubs).
- Make sure young children and inexperienced swimmers always wear U.S. Coast Guard-approved life jackets around natural water and swimming pools.
- Always be cautious around natural bodies of water, which can contain hidden hazards like dangerous currents, underwater objects and limited visibility.
- Always wear a life jacket when boating – most boating fatalities occur from drowning.
- Avoid drinking alcohol before or during swimming, boating, and other water activities, and while you’re supervising children.
- Don’t hyperventilate or hold your breath for long periods of time in water – this can result in “hypoxic blackout” or “shallow water blackout.”
- If you have a pool or hot tub, or live near a body of water, always keep reach-and-throw equipment, a cell phone, life jackets and a first aid kit nearby in case of an emergency.
Following these helpful tips, taking the proper precautions and using your common sense can go a long way towards helping you stay safe and healthy all summer long. If you or someone you’re with shows signs of a heat-related illness or is a victim of a drowning incident, it’s important to seek proper medical attention immediately and – in cases of emergency – call 9-1-1.
