We've been having a bit of a heat wave here this week, with temperatures in the nineties and way too much humidity. Our thermostat is currently set to 78; this feels really nice when coming in from outside, but too warm when we're trying to sleep. Here are some ways to stay cool without fiddling with the thermostat:
Close the curtains to keep sunlight (and heat) out.
Keep a bottle of lotion in the refrigerator. Apply liberally.
Fill a spray bottle with water and keep it in the refrigerator. Give your face a spritz every so often.
Wear loose-fitting clothing in breathable fabrics (like cotton).
Stick your pillow in the freezer for half an hour before bed. (I haven't tried this; my pillow would probably end up smelling like chicken and ground beef.)
Cool The House (Or Leave It!):
Turn on some fans.
Try not to use the oven, stove, or clothes dryer.
Keep the lights off as much as possible.
Have a water fight (outside, of course!). Forget little water pistols; grab the garden hose!
Hang out somewhere that uses air conditioning liberally, like the mall or library. Or the frozen section of the grocery store.
Take a COLD shower.
Drink a glass of ice water.
Eat a popsicle, or some ice cream.
Soak a bandana in cold water and tie it around your neck.
Try using a lotion or body wash containing mint, which has a cooling effect.
