COLOMBO – The Department of Meteorology has issued a critical advisory as a heat wave sweeps across the island. The Heat Index—the actual temperature felt by the human body—is expected to climb to the ‘Caution’ level (38°C–42°C) in the Western, Sabaragamuwa, Southern, and North-Western provinces, along with the Anuradhapura, Monaragala, Mannar, and Vavuniya districts.
This isn’t just about “feeling hot.” At these levels, prolonged exposure can lead to fatigue, heat cramps, and life-threatening heatstroke. As your news editor, I’ve compiled this essential guide to help you protect your loved ones, your vehicles, and your livelihood.
Protecting Your Loved Ones
The most vulnerable are children under four, adults over 60, and those with pre-existing heart or kidney conditions.
- Hydrate Constantly: Don’t wait until you are thirsty. Adults should aim for at least 2.5 to 3 liters of water daily. Stick to natural coolers like King Coconut (Thambili) and avoid sugary or caffeinated drinks which can worsen dehydration.
- Dress Smart: Wear light-colored, loose-fitting cotton clothing. Dark colors absorb heat, making you feel several degrees warmer.
- The Golden Rule for Parents: NEVER leave a child or a pet in a parked vehicle, even for a minute. In this weather, the temperature inside a car can reach fatal levels in less than 10 minutes.
- Shift Your Schedule: If you exercise or work outdoors, do so before 7:30 AM or after 5:00 PM.
Safeguarding Your Home & Property
Your house can become an oven if not managed correctly.
- Seal the Heat Out: During the day (8:00 AM – 5:00 PM), keep windows and curtains closed to block direct sunlight. Open them at night to let the cooler air circulate.
- The Fan Trap: Be careful—when the air temperature exceeds 35°C, fans may actually blow hot air onto your body, increasing the risk of heat exhaustion. Use them in combination with damp cloths on your skin for evaporative cooling.
- Electrical Safety: Heat causes electrical components to work harder. Unplug unnecessary appliances to reduce internal heat and prevent potential short circuits.
Protecting Your Vehicle
Extreme heat is a silent killer for car engines and tires.
- Check Tire Pressure: Heat causes air to expand. Over-inflated tires are at a higher risk of blowouts on the highway.
- Coolant Levels: Ensure your radiator is topped up with coolant (not just plain water) to prevent the engine from seizing in traffic.
- Park in Shade: Whenever possible, use covered parking. If parking outside, use a sunshade on the windshield to protect your dashboard from cracking.
Saving Your Crops and Garden
For our farmers and home gardeners, the next few days are critical.
- Mulching is Key: Cover the soil around your plants with straw, dried leaves, or “Vaisakhi” grass. This keeps the roots cool and prevents moisture from evaporating.
- Watering Times: Only water your plants in the very early morning or late evening. Watering during the noon heat can actually “cook” the roots and waste water through instant evaporation.
- Temporary Shade: Use green nets or cadjan leaves to provide temporary shade for sensitive nursery plants and young vegetables.
Know the Warning Signs
If you or someone nearby starts feeling dizzy, nauseous, or stops sweating despite the heat, act immediately. Move them to a cool, shaded area, apply wet towels to their neck and armpits, and seek medical help.
Stay safe, stay hydrated, and look out for your neighbors.
