Essential Tips to Keep Your Home Cool During a Heatwave

As temperatures in Ireland soar, with forecasts predicting highs of 27 degrees Celsius, residents are increasingly seeking effective strategies to maintain comfort within their homes during heatwaves. According to a recent report by Energia, common household habits may inadvertently contribute to increased indoor temperatures, making it crucial for homeowners to implement changes to mitigate heat accumulation.

The significance of this issue is underscored by the potential health risks associated with extreme heat, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. The World Health Organization has noted that heat-related illnesses can lead to increased hospitalizations and fatalities, emphasizing the importance of maintaining a cool living environment (World Health Organization, 2021).

### Common Mistakes to Avoid during Heatwaves

1. **Keeping Windows Open During the Day**: While it may seem inviting to open windows for fresh air, during peak heat hours—typically from noon until 4 PM—outdoor temperatures can surpass indoor levels. Energia advises homeowners to keep windows closed during these hours, as allowing hot air to enter can exacerbate indoor heat buildup (Energia, 2025).

2. **Leaving Curtains or Blinds Open**: Sunlight streaming through windows can significantly increase indoor temperatures, particularly in rooms that receive direct sun exposure. According to Energia, direct sunlight can elevate room temperatures by as much as 7 degrees Celsius within a few hours. Homeowners are encouraged to close curtains or blinds during the hottest parts of the day to effectively block this heat (Energia, 2025).

3. **Using Heat-Generating Appliances**: Appliances such as ovens, tumble dryers, and hairdryers generate considerable heat when in use. Utilizing these devices during the hottest times of the day can raise indoor temperatures further. Instead, homeowners should consider preparing cold meals or using microwaves and outdoor drying options during these peak heat hours (Energia, 2025).

4. **Keeping Electronics Plugged In**: Even when turned off, devices like televisions, gaming consoles, and chargers can produce heat when plugged in. The Irish Institute of Technology emphasizes that this phenomenon can contribute to an increase in indoor temperatures, especially in smaller, poorly ventilated spaces. Using power strips to easily unplug multiple devices can help reduce this heat buildup (Irish Institute of Technology, 2023).

5. **Leaving Lights On**: Traditional incandescent bulbs emit substantial heat, and leaving them on unnecessarily contributes to indoor warmth. Experts recommend switching to energy-efficient LED bulbs, which produce less heat and consume less electricity. Furthermore, turning off lights when not in use is an easy yet effective way to lower indoor temperatures (Energia, 2025).

### Broader Implications

The implications of rising temperatures extend beyond mere discomfort; they pose significant health risks, particularly for vulnerable groups. The Centers for Disease Control and Prevention (CDC) has reported that prolonged exposure to high temperatures can lead to heat exhaustion, heat stroke, and exacerbation of chronic conditions (CDC, 2022). Moreover, the economic impact of increased energy consumption during heatwaves can strain both household budgets and local energy resources.

### Future Outlook

As climate change continues to influence weather patterns, the frequency and intensity of heatwaves are expected to rise. A study published in the Journal of Climate Change and Health (2023) indicates that residents in temperate regions may need to adapt their living environments to cope with increasingly extreme weather conditions. This adaptation may involve more than just immediate changes; it could lead to broader societal shifts in how homes are designed and constructed to withstand higher temperatures.

In conclusion, by identifying and rectifying common mistakes, homeowners can significantly enhance their comfort during heatwaves. Implementing simple strategies not only improves indoor living conditions but also contributes to overall health and wellness. As extreme weather events become more prevalent, such adjustments will be paramount to maintaining a safe and livable environment.
