The secret to keeping your bedroom cool on hot summer nights

It’s official – the chill of winter is just a memory and we can emerge from our warm, stuffy burrows to sniff the air and greet the sun. Although summer brings an invigorating feeling of freedom from bundling up in woolly layers and hogging the heater, clammy summer nights frequently impair effective sleep. Here’s how to keep cool in the bedroom and increase all-important rest time.

Love your linen
Bedlinen has a significant effect on sleep quality. In hot weather, the prime factors are breathability, and moisture-wicking, the ability of fabric to draw moisture from skin to outer layers of clothing or release it into the air. Natural fabrics are more effective at this than blends containing polyester or other synthetics. Cotton and linen are superb for breathability, and bamboo has superior moisture-wicking abilities.

Open wide
It’s been proven that a cool bedroom, around 18 to 20°C, promotes restful sleep, even in winter. A well-ventilated room is essential to prevent a stuffy atmosphere that gets warmer during the night. Without resorting to power-hungry air-con, try opening windows to take advantage of lower night temperatures and fresh air.

Tip: If bedroom windows are exposed to full sun during the day, keep them closed and curtains and blinds drawn to stop heat build-up. Open them when the sun goes down and temperatures drop.

7 ways to create a more energy efficient home

1. Ventilate naturally

Make sure your home has plenty of natural ventilation and light, says Jeff Angel of the Total Environment Centre.

“Cross-ventilation will enable it to get as much airflow through as possible, with cooling breezes in summer that means you don’t have to use airconditioning as much, if at all.”

Orienting a new home carefully and making sure it has a well-designed layout will help, but houses can also be renovated to introduce greater airflow with the use of louvres, too.”

Windows in areas that will see more sunlight, as well as the use of skylights, will also make a home brighter without the need for constant artificial lighting.

2. Seal the home

There are times when you’ll want to seal your house off completely from the outside to maintain a constant temperature inside. That’s when installing good insulation in the roof space and walls, effective water and draught proofing and double-glazing makes all the difference.

“That’s about making your house an excellent esky,” says architect Tone Wheeler of the Environa Studio. “It will help to preserve heat in winter and keep it cool in the hottest part of a mid-summer day.”
