Close your curtainsAround 30% of unwanted heat comes from your windows, so closing them and shutting the curtains can lower the temperature of your home. It may be tempting to fling the windows open, but it’s important to keep them closed, especially in the bedroom, to keep the humidity out. Sleep aloneCuddling might be on the table during the winter months but it’s the last thing you want during the muggy nights. This will blow the hot air out and cool the air coming in. Open windows at nightOnce the sun has gone down, open the windows to let in the cooler night air and some of the pent-up humidity out.
