Little Green Idea – Keep Your Cool This Summer

On hot summer days a breath of cool air-conditioning can provide much-needed refreshment. However, constantly running the AC is hard on your wallet and the planet.

So, how can we keep cool without racking up financial and ecological debt?

• Wear loose, lightweight clothing. This is not only cool but can provide good sun protection if chosen well. Natural fibres allow easier air flow.
• Eat light and cool. Summer salads, microwaved vegetables and cooking small food items on the barbeque all keep your house (and you) cooler. If you must turn on the stovetop or oven, try to choose meals that cook quickly such as stir-fries rather than roasts or casseroles.
• Drink plenty of water. Many girls carry around water bottles and sip, but do not drink deeply. Having several substantial drinks each day will help you to keep well hydrated on sweaty days. Sydney tap water is a very healthy and environmentally friendly choice for drinking.
• Take quick, cool showers. These save energy both from water heating and home cooling, as well as saving water. A short, cool shower before bed can help you to sleep on warm nights.
• Close your curtains and blinds during the day to block out the heat. At night, open them to allow breezes to flow and cool the rooms naturally.
• Use fans to encourage air flow and help sweat to evaporate. These can dramatically cut the need for air conditioning.
• Hang out at the shops. The shopping centres are running air conditioning, so you may want to take advantage of this during the hottest times of day.
• Make large ice blocks for your pet. Our dogs and cats get hot, too! A large ice block made in an ice cream container can provide much-needed coolness and hydration on a hot day. If you add a little bit of stock (not too much, as it will be very salty) or some kibble, your pet will have tasty, cool fun.

With the tips above you can enjoy your air conditioning in moderation, save money and shrink your ecological footprint.
