Stay Cool This Summer, Sustainably

As temperatures rise and heatwaves become more frequent, staying cool in summer is more essential than ever. But blasting the air conditioner all day isn’t great for the planet and some of us don’t even have access to it! Luckily, there are simple, sustainable ways to beat the heat without contributing to climate change. Here’s how to stay cool the eco-friendly way this summer.

1. Rethink Your Space

Start by keeping heat out. Close blinds or curtains during the hottest parts of the day to block sunlight. Opt for light-coloured window coverings that reflect rather than absorb heat. In the evening, open windows to let cooler air in and use cross-ventilation to flush warm air out. Ceiling or standing fans use far less electricity than AC and can be surprisingly effective when combined with open windows or a bowl of ice.

2. Switch to Natural Fibres

Your clothing and bedding choices matter. Linen, cotton, and bamboo fabrics breathe better than synthetic materials, helping your body regulate temperature more naturally. Swap heavy duvets for lightweight sheets and wear loose-fitting, light-coloured clothes to stay comfortable.

3. Go Green—Literally

Plants don’t just brighten up a room—they help cool it down. Strategic placement of indoor plants can lower indoor air temperatures through a process called transpiration. Outdoors, shade trees and climbing vines can cool your home’s exterior walls and reduce the heat island effect.

4. Cook Smart

Avoid heating up your home with ovens or stovetops. Summer is the perfect time for fresh salads, cold soups, or meals cooked on an outdoor grill. Even small appliances like toaster ovens or air fryers use less energy and generate less heat than traditional ovens.

5. Upgrade Efficiently

If air conditioning is necessary, consider an energy-efficient model or a smart thermostat that learns your habits and reduces unnecessary usage. Look for ENERGY STAR-certified appliances and keep filters clean to maximise performance.

6. Hydrate & Cool Down Naturally

Sometimes the simplest tricks are the most effective: stay hydrated, take cool showers, or apply a damp cloth to pulse points like your wrists and neck. These small habits help regulate body temperature and reduce the need for external cooling.

By combining a few of these sustainable strategies, you can stay cool and comfortable this summer, without heating up the planet. 🌱
