Houseplants tend to be comfortable with the same temperatures their owners prefer. They can handle the daytime heat, the nighttime chill, and, of course, room temperature. But just as you shrug your shoulders when brushed with a burst of chilly wind, houseplants can be decimated by a cold draft. So, you shouldn't keep yours near a drafty window, a door that is constantly opening and closing, or a window or wall that's poorly insulated. If need be you can make a draft blocker for your window or learn to fix a leaky door. Just remember to put yourself in your indoor plant's shoes.
