How to stay cool without aircon during extreme heat
Stay hydrated, stay indoors when you can, and remember: Even without air conditioning, you have the power to keep your home cooler and your body safer.
Allow cooler air to circulate throughout your home by opening your windows at night.
The Philippines is no stranger to heat, but this summer has pushed temperatures — and people — to the brink. The heat index, which measures what the temperature feels like when humidity is factored in, has consistently soared past 40°C in many parts of the country. In some areas, it has reached a scorching 45°C to 47°C, prompting warnings from health and weather authorities to stay indoors and stay hydrated.
This level of heat is not just uncomfortable — it’s dangerous. High heat index levels can lead to heat exhaustion, dehydration, and even heat stroke, especially for the elderly, children, and those with pre-existing health conditions. For many Filipinos, the natural response is to blast the air conditioning. But with rising electricity costs and concerns about sustainability, not everyone can — or wants to — rely on AC 24/7.
Thankfully, there are several low-cost, energy-saving ways to cool your home and body without air conditioning. Here are practical tips to beat the heat:
1.Open your windows at night
If you’re in an area where the evening temperature drops even slightly, take advantage of this by opening your windows at night. This allows cooler air to circulate throughout your home. Just remember to shut them early in the morning before the sun starts heating things up again.
Keep blinds, curtains, or shades drawn during peak sun hours.
2. Keep your curtains closed during the day
Sunlight streaming through your windows brings in more than light — it brings heat. Keep blinds, curtains, or shades drawn during peak sun hours (usually 10 a.m. to 4 p.m.). Use light-colored or reflective curtains to block and reflect heat away from the room.
Switching LED light bulbs reduces room heat.
3. Switch to LED bulbs
Traditional incandescent bulbs waste about 90 percent of their energy as heat. Swapping them out for LED or CFL bulbs not only reduces room heat but also lowers your electric bill.
4. Cook after sunset (or take it outside)
Ovens, stovetops, and even rice cookers radiate a lot of heat. If you need to cook, do it after the sun has set — or better yet, take your cooking outdoors and fire up the grill. Bonus: You’ll avoid making your kitchen feel like a sauna.
