The temperature. Also, thermal conductivity.
Your breath should be warmer than room temperature unless you are a zombie! I am guessing you are asking why does blowing on your wet finger feel colder even though your breath is warm? Moving air allows the water on a wet finger to evaporate faster. Evaporation of a liquid to a gas requires energy and the water is taking that energy from your finger. Less energy means a lower temperature and your finger gets cold.
Evaporative cooling. As the water evaporates from your body it takes with it a good deal of energy (heat) as the latent heat of vaporisation
Why does ice seem much colder to the teeth than ice water; even though they may be out the same temperature
Even though the temperature is so high, one would not feel warm in the thermosphere, because it is so near vacuum that there is not enough contact with the few atoms of gas to transfer much heat. Related links are mentioned below.
If the temperature is low , the air will feel cold.
The Thermosphere feels very cold to us because of its low Thermal Energy.There are very few particles in the Thermosphere, so even if they were very, very hot, it would feel cold.
Cold air is relative to your skin temperature. if your skin is 98.6*f, than 90*f air blowing over it will actually feel cool, albeit not very cold, even though when it is 90*f outside it is considered hot outside.
When they feel hot they think it's hot n feel cold then they feel cold
because they have just exercised.
Our body temperature is high then cold water so when it comes in contact with our body energy in the form of heat is transferred from body to water so it decreases our body temperature and we feel cold.
