As climate change intensifies, the Philippines is experiencing longer, hotter, and harsher dry seasons. Extreme heat waves—once rare—are now common, with temperatures often soaring above 40°C and heat indices reaching dangerous levels. For Filipino families, this means one thing: protecting your home and staying cool isn't just about comfort—it’s about safety.

Whether you're living in your own house or renting a home through platforms like RentPH, preparing your space for extreme heat is a necessity. This guide offers practical, budget-friendly, and family-safe ways to keep your home comfortable, energy-efficient, and protected.

🌞 Why Extreme Heat Is Becoming a Bigger Problem in the Philippines

In recent years, PAGASA’s heat alerts have become more frequent. Longer dry spells, El Niño cycles, and climate change all contribute to rising temperatures. Extreme heat affects:

• Your health – heatstroke, dehydration, dizziness

• Your home – warped doors, cracked paint, damaged appliances

• Your electricity bill – skyrocketing because of 24/7 cooling appliances

• Your overall comfort – especially for kids, seniors, and pets

This is why preparing your home for heat waves should happen before temperatures spike.

🏡 Practical Ways to Prepare Your Home for Extreme Heat

Below are effective and realistic steps Filipino families can take to cool down their homes—even on a budget.

1. Improve Ventilation and Airflow

Proper airflow is your first defense against extreme heat.

✔️ Open windows strategically

Open opposite windows to create cross-ventilation, especially during early morning and late afternoon.

✔️ Use electric fans efficiently

• Set fans near windows to drive hot air out.

• Use ceiling fans counterclockwise to push cool air downward.

✔️ Install window or wall vents

These small installations help reduce indoor heat buildup.

If you’re renting, you can always ask the landlord for simple improvements. RentPH-listed homes often highlight good ventilation—something worth checking when choosing a rental unit.

2. Keep Sunlight Out During Peak Heat Hours

The sun between 10 AM to 4 PM is the hottest. Block it before it heats your home.

✔️ Use blackout curtains or thermal drapes

These can cut heat by up to 40%.

✔️ Install reflective window film

Affordable and renter-friendly—no drilling required.

✔️ Add blinds or roll-up shades

Great for west-facing windows that catch the afternoon sun.

3. Cool Down Your Roof (It’s Where the Heat Starts)

Your roof absorbs the most heat, and most homes in the Philippines have metal roofing that gets extremely hot.

Here’s what you can do:

✔️ Apply heat-reflective roof paint

This can lower indoor temperatures by 2–4°C.

✔️ Install insulation

Foam or fiberglass insulation keeps heat from entering the home.

✔️ Consider a “green roof”

Plants help cool surfaces—ideal for houses with flat roofs.

Many rental homes on RentPH already have insulated roofing—something to look for when choosing a comfortable home.

4. Keep Your Walls Cool

Walls trap heat, especially concrete ones. Try:

✔️ Exterior wall paint in light colors

White, beige, or light yellow reflects (not absorbs) heat.

✔️ Install wall insulation

Even thin insulation boards make a huge difference.

5. Switch to Heat-Friendly Appliances

Whether renting or owning, your appliances play a major role in indoor temperature.

✔️ Use inverter appliances

They run cooler and consume less electricity.

✔️ Choose LED lights over incandescent bulbs

LED lights produce very little heat.

✔️ Unplug unused devices

Chargers, TV boxes, and modems generate heat even on standby.

6. Set Up a Natural Cooling System

Natural cooling is budget-friendly and effective.

✔️ Add indoor plants

Plants like snake plant, rubber plant, and peace lily improve humidity and temperature naturally.

✔️ Place bowls of ice in front of fans

A quick hack for instant cool air.

✔️ Use clay pots for cooling

They help regulate indoor humidity.

7. Manage Indoor Humidity

Humid air makes heat feel more intense.

✔️ Use dehumidifiers or moisture absorbers

Affordable options are available in hardware stores.

✔️ Keep doors open between rooms

Prevents hot air from being trapped.

✔️ Repair water leaks

Leaks increase moisture and heat discomfort.

8. Protect Your Home’s Structural Integrity

High temperatures can damage parts of your home.

Heat can cause:

• Cracks on walls

• Loose tiles

• Warped wooden doors

• Faded paint

Preventive steps:

• Repaint every few years

• Seal cracks early

• Maintain proper roofing

• Inspect plumbing and pipes

If you’re renting, a well-maintained home is a must. RentPH makes this easier by connecting renters to property managers who ensure regular home upkeep.

9. Create a Cool Sleeping Environment

Sleep is affected the most during extreme heat.

✔️ Use breathable fabrics

Cotton or bamboo sheets are lightweight and cool.

✔️ Freeze water bottles

Wrap them in towels to make DIY “cool packs.”

✔️ Sleep in the lowest part of the house

Heat rises, so ground-level rooms are cooler.

10. Prepare for Power Interruptions

Brownouts happen more often during heat waves because grids become overloaded.

✔️ Charge power banks and fans

Always keep portable fans ready.

✔️ Store extra water

Heat = faster dehydration.

✔️ Keep your home shaded

Use curtains and shades proactively.

💧 Keep Yourself and Your Family Safe Too

Protect your household by forming good habits:

• Drink water every hour

• Avoid outdoor activities at noon

• Give pets access to shade

• Check on kids and seniors regularly

• Never leave anyone inside a parked vehicle

Extreme heat is not just uncomfortable—it can be fatal. Taking it seriously is a form of home preparedness and family care.
