Haunted rooms are always especially cold: What exactly is a cold spot?

In ghost stories, there is a detail that almost always appears: you walk into a certain room and suddenly feel cold, cold enough to shiver, with your hairs standing on end. Some say it's like a cool breeze blowing past you; others say it's like something is pressed against your back.

People who investigate the paranormal call such places "cold spots." They pull out thermometers and find that a certain corner is indeed two or three degrees lower than the surrounding area, and they become convinced that a ghost is there.

But cold spots in a house are very common. The most common cause is gaps. Old houses have doors and windows that don't close properly, and corners, floors, chimneys, and vents always have drafts, with cold air seeping in bit by bit. When a person stands there, they feel cold. Warm air rises, cold air sinks, and in a room, there is natural convection, flowing along walls, staircases, and stairwells, forming bands of cold. Then there is another kind of cold—not from the air, but from the surface: an old stone wall, a single-pane glass window, temperatures far lower than the body. When a person stands nearby, their body heat constantly disperses toward it, making them feel cold.

Another kind of cold is in the mind. When a person is nervous or afraid, their skin gets goosebumps and their spine feels chilled. This reaction is produced by themselves and has nothing to do with the room's temperature. So after being told "this place is haunted," when they walk in, they are more likely to feel cold.

In 2001, British psychologist Wiseman's team recruited hundreds of volunteers to visit two famous "haunted" places: Hampton Court near London, and Edinburgh's underground vaults. The volunteers didn't know where the legendary "haunted zones" were. They walked around separately and wrote down where they felt something strange. The result was that their reports concentrated in those legendary places, and these places shared common characteristics: dim lighting, small spaces, or winding layouts. The researchers concluded that the environment itself could make people feel "something is off here," without any ghosts needing to appear.

So if you encounter a cold spot in your home, you can do a small experiment: light an incense stick and bring the smoke close to that position, and see which way the smoke drifts. If the smoke is blown at an angle, it means there is a draft; if the smoke goes straight up, then measure the temperature again, comparing day and night. Most of the time, you will find a gap. Tape it up with adhesive tape, and the cold spot will disappear.
