Some homes seem to hold onto the cold even with every window shut. Meanwhile, the neighbor’s apartment in the same building feels a lot more comfortable. That kind of difference isn’t random — there’s real physics behind it.
Why some rooms get colder than others
Factors like a room’s sun exposure, wall insulation, flooring type, and even which floor of the building it’s on directly affect how heat is retained. Rooms with little direct sunlight and cold flooring (tile, porcelain) tend to cool down faster and take longer to warm up.
Effects of staying in a cold room for a long time
– Constant low-grade discomfort: the body spends extra energy trying to maintain temperature, causing subtle fatigue.
– Cold hands and feet for longer: extremities lose heat faster in cold environments.
– Harder to relax at night: sleeping in a very cold room can disrupt the body’s natural wind-down process.
– More muscle stiffness: muscles tend to tense up more in low temperatures.
These are general effects of thermal discomfort, not a medical issue — people with specific conditions should follow professional guidance on cold exposure.
How to solve the problem
Full thermal insulation is expensive and not always possible in rental properties. For rooms that stay cold even closed up, a portable space heater solves the problem on the spot, heating only the room that needs it without any renovation.
