Energy companies and green experts already recommend bathing, doing laundry and cooking during cooler times of the day, which can also help you control the heat in your home. If you have to use the shower, washer, or oven in the heat of day, counteract the heat rise by helping control the humidity. "Turn on ventilating fans to help extract warm, moist air, but be sure to turn them off when you're finished so they don't extract cooled air from the house," said HomeTips.
Get a ceiling fan
A ceiling fan doesn't lower the temperature in the room, but it can make you more comfortable by circulating the air, allowing you to give your AC a break, or at least turn it down.
Get a whole house fan
A whole house fan can use as little as 10–20% of the energy expended by an AC unit, depending on the size of the unit. "A whole-house fan ($1,000 to $1,600, including install) exhausts hot inside air out through roof vents," said Houselogic.
Take a look at your sheets
Getting through the day during a steamy summer may not be a problem, especially if you work outside of the house. But those nights when the temps don't go down can be unbearable. Sheets made of certain materials can make it worse, but new options can help.
"Cool bed sheets are made with natural fibers that are breathable and can prevent perspiration or feature moisture-wicking fabrics that whisk your sweat away faster than you can produce it — so you'll stay dry through the night," said Bustle. "Considering that the ideal temperature for sleep is between 60 and 67 degrees, it stands to reason that sleeping with sheets that keep you cool can make your bed feel less like a sauna is a very good idea."
Look for natural fibers like cotton (especially Egyptian) or bamboo, and away from sateen and silk.
