The prolonged period of extreme heat continues to pose a significant health risk, with emergency room doctors seeing a surge in patients suffering from heat exhaustion. While we may think we’re doing everything to keep cool, the blistering temperatures can take a toll on our bodies before we even realize it. Here’s what experts want you to know:
The Dangers of Dehydration and Heat Exhaustion:
Even a short period of exposure to extreme heat, as little as 20 to 30 minutes, can lead to rapid water loss. This dehydration can catch up to anyone, but it’s particularly dangerous for individuals working outdoors, those without air conditioning, and people with chronic health conditions.
Dr. Rafael Chavez, an emergency medicine physician at Providence St. Joseph Medical Center, highlights the increased risk for individuals with diabetes. They experience higher blood sugar levels during heat, leading to increased urination and further dehydration, creating a vicious cycle. Similar concerns exist for those with chronic heart failure and individuals taking diuretic medications, who are already predisposed to dehydration.
Even spending time at the beach or pool doesn’t guarantee safety from heat exhaustion. While we may feel cool in the water, we’re still exposed to the heat and continue to sweat, leading to dehydration.
Protecting Vulnerable Individuals:
Newborns, in particular, are highly vulnerable to heat. They cannot sweat and are at extreme risk if covered with blankets in strollers. This practice is as dangerous as leaving a child in a locked car and should be avoided at all costs. Dr. Diana Lev of Dignity Health Northridge Hospital Medical Center stresses the importance of taking extra precautions with infants during scorching temperatures.
Staying Safe During Extreme Heat:
While the general advice is to avoid strenuous activities like exercise or walking pets during the hottest part of the day, even late-night outings aren’t entirely safe. Temperatures often remain dangerously high even after sunset, so it’s crucial to seek activities early in the morning.
Key Tips for Staying Safe:
*
Stay Hydrated:
Drink water every 20 minutes throughout the day.*
Limit Sun Exposure:
Avoid direct sunlight during the hottest hours.*
Seek Air Conditioning:

Stay Aware of Symptoms:
Watch out for signs of heat exhaustion, such as dizziness, nausea, headache, and muscle cramps. If you experience any of these symptoms, seek medical attention immediately.By taking these precautions and staying informed, you can better protect yourself and your loved ones from the dangers of extreme heat.
