A simple two-minute task performed every morning can make the difference between a hot and a cool home during summer, without relying on air conditioning or fans. The trick involves closing curtains and blinds early in the day, before the sun fully heats the house, to block sunlight and reduce heat absorption.
Why UK Homes Overheat
UK summers are becoming increasingly warmer, with heatwaves now a regular part of the season. Unlike many countries, most homes in the UK lack built-in air conditioning, and portable fans often struggle to make a real difference. Keeping indoor spaces such as bedrooms cool during hot weather can be challenging. Hot weather in the UK feels particularly intense because homes are designed to retain heat rather than release it. This makes cooling strategies that don't rely on electricity important.
The 2-Minute Morning Task
One of the most effective ways to block the sun and heat out is to control sunlight throughout the day. Sunlight beaming through windows can quickly turn a room into a greenhouse, especially during peak afternoon hours. That is why many people, including the author, close curtains and blinds early in the morning before the sun fully heats the house.
When sunlight enters through the window, it heats up floors, walls, and furniture, which then radiate warmth back into the room. By keeping curtains and blinds closed during the hottest part of the day, heat absorption is massively reduced. Blackout curtains or weighted curtains can be even more effective, but standard curtains can also make a noticeable difference.
Ventilate at the Right Time
Once the outside temperature drops in the evening, it becomes the perfect time to open curtains, blinds, and windows. Cross-ventilation works best, which involves opening windows on opposite sides of the house to create effective airflow. If complete darkness is not desired, Brits can angle blinds to reduce glare while still blocking direct sunlight.
Additional Cooling Tips
Alongside managing curtains and airflow, other small adjustments can make UK summers more bearable. These include avoiding the use of ovens or tumble dryers during the hottest part of the day, as well as using frozen hot water bottles at night to stay cool.
