household electricity users, especially in warmer countries. It is therefore necessary to limit its use as much as possible in order to save energy and reduce the effects of the greenhouse gas emissions associated with electricity generation. Take a quick look at these 12 ways that you can keep your room cool without air conditioning:
- Keep the blinds or curtains closed, especially on windows facing towards the sun. Apparently, up to 30% of unwanted heat enters through the windows of your house. Covering the windows insulates the room, and reduces the entrance of heat, keeping you cooler for longer¹.
- Set up a fan to blow across a bowl of ice, or something equally cold. This will have the effect of circulating cold, misty air through the room – something an air conditioner can’t even do¹.
- Let the hot air out at night to ensure that your house is a cool as possible the next morning. This can involve opening windows and doors and setting up fans to force the hot air out of the house. However, this won’t work if you are unfortunate enough to live in a place where it remains hot 24 hours a day¹.
- As crazy as it sounds, freezing your sheets can work wonders in helping you fall asleep. Simply throw your sheets in the freezer a few hours before you go to bed, and prepare for a wonderful period of coolness when bedtime comes².
- Turn off lights and other electrical appliances when they aren’t in use. Anything which uses electricity will generate heat, and therefore will warm up the room. Turning them off will help keep you cooler for longer³.
- Although this method involves some form of long-term planning, shading your house with trees and shrubs can dramatically reduce the amount of heat which finds its way into your house. However, be careful planting too much shrubbery close to the house if you live in a fire-prone area³.
- Make sure your home has adequate insulation. Not only does insulation keep heat in during those cooler winter months, it is equally efficient at keeping heat out during the summer³.
- Seal any leaky doors or windows. Any opening which allows the free movement of air will allow the entrance of hot air. Cover or remove these gaps to keep yourself cool. This could also include weatherproofing a single room³.
- If you are lucky enough to have a basement, you can use a fan to circulate the cool underground air through the rest of the house⁴.
- Avoid steamy, heat creating activities. Don’t take hot showers, cook, or wash dishes during the hottest part of the day. Doing so will only serve to heat up the room even more, making it simply unbearable. Rather, wait until later in the evening when it has begun to cool down⁴.
- Use pale coloured roofing if you have a choice. This will reflect heat, rather than absorbing it as a darker roof would⁴.
- Turn on your bathroom and kitchen fans in the evening, as they will both work to pull the heat out of the house, replacing it with cooler night air¹.
