Heatwaves: Prepare and Protect Yourself

Heatwaves are a frequent occurrence in Athens during the summer months. These extended periods of excessively high temperatures demand vigilance and proactive measures to safeguard your health. Here’s how to stay safe during a heatwave:  

• Hydration is Your Best Defense: Drink plenty of water throughout the day, even if you don’t feel thirsty. Carry a reusable water bottle and refill it frequently. Electrolyte drinks can help replenish lost salts.  
• Time Your Explorations: Schedule your outdoor activities for the cooler parts of the day, such as early mornings or late afternoons. Avoid strenuous activities during the peak heat of midday (11 am to 4 pm).
• Find Refuge in Shade and Air Conditioning: When you’re outdoors, take frequent breaks in shaded areas. Spend time in air-conditioned environments like museums, shopping malls, cafes, and your hotel room to regulate your body temperature.
• Dress to Beat the Heat: Wear loose-fitting, light-colored clothing made from breathable fabrics like cotton and linen. A wide-brimmed hat will protect your face and head, and sunglasses are essential for shielding your eyes from the intense glare.  
• Listen to Your Body’s Signals: Pay close attention to any signs of heat exhaustion, such as dizziness, headache, nausea, or excessive sweating. If you experience these symptoms, find a cool place to rest, rehydrate, and seek medical assistance if necessary.
• Prioritize Vulnerable Groups: The elderly, young children, pregnant women, and those with pre-existing health conditions are more susceptible to heat-related illnesses. Ensure they stay hydrated, cool, and avoid excessive sun exposure.  
• Stay Informed: Keep an eye on weather forecasts and pay attention to any heatwave warnings issued by local authorities.
