How to Keep Your House Cool in Extreme Heat

As summers become increasingly intense around the globe, staying cool at home isn’t just about comfort—it’s a matter of health and safety. 

Prolonged heatwaves put stress on our living environments, often making even the indoors feel unbearable. While air conditioning helps, it’s not always efficient—or affordable—if not managed properly. 

Fortunately, there are ways to keep your space cooler while staying energy-conscious, especially with modern smart home technology, like smart thermostats.

The Health Risks of Heatwaves

During extreme heat events, the best defense is staying indoors. 

Unfortunately, being inside isn’t always enough to shield us from the risks. High temperatures can trigger a wide range of physical symptoms, including:

• Persistent headaches
• Itchy or irritated skin
• Dizziness or nausea
• Dehydration
• Heatstroke
• Vomiting

What’s more concerning is the decline in air quality that often accompanies a heatwave. Higher temperatures intensify ozone and particulate pollution, even inside homes. 

Wildfires and droughts only add to the issue, releasing dangerous pollutants like carbon monoxide. 

Without proper ventilation, indoor air can trap these contaminants, increasing the risk of respiratory problems—especially among children, seniors, and those with existing conditions.

Practical Ways to Keep Your Home Cool During a Heatwave

It’s essential to prepare your home before the heat strikes. Here are a few proven strategies:

1. Install or Upgrade Air Conditioning

An effective AC unit is your first line of defense. But not all systems are created equal. Older models tend to be energy-hungry, while newer, ductless AC units are designed to cool efficiently and cost less to operate. 

According to the U.S. Department of Energy, cooling accounts for around $29 billion annually in electricity costs across the country. 

Investing in modern cooling solutions, like smart thermostats lets you control temperatures remotely, turn systems on only when needed with smart schedules, and keep energy bills in check.

2. Use Nighttime Ventilation

Although daytime heat can trap your home in a stifling atmosphere, temperatures typically drop during the night. 

Take advantage of this natural cooldown by opening windows after sunset. Even just a 15-minute airing session helps flush out stale indoor air and replace it with fresher, less polluted outdoor air. 

Studies show indoor air can be several times more polluted than the air outside, so this simple routine can make a big difference.
