Usually we identify them by touching. But we cannot always rely on our sense of touch to decide whether an object is hot or cold.
Because your senses can only sense heat flow, your skin temperature and the conductivity are factors in how something feels, not just the temperature of the object. Our biology just isn’t designed to determine objective temperatures. We can only tell how it feels, not what it really is.
You use your sense of temperature to observe how hot or cold objects or your surroundings are. The sense of temperature is made up of distinct sensory receptors for hot and cold located in the dermis. There are more receptors for cold than for hot. As with the sense of touch, every part of your skin senses temperature.
These two studies establish that, as a screening procedure, touch will seriously overestimate the incidence of fever, but with touch, fever will rarely be missed; also, a patient who does not feel hot is very likely not to have fever. A child who feels hot needs to have a temperature taken before fever is diagnosed.
Your skin can’t actually detect the temperature of other objects—it only senses its own temperature. When you touch a piece of metal that is colder than your hand, your fingers rapidly lose heat and feel cold—and the opposite happens when you touch metal that is hotter than your hand.
