Why are my fingers colder than room temperature?

So, I was using a thermocouple at work. It showed ambient temperature at around 18°C. When I held the thermocouple with my fingers, I noticed that the temperature reading dropped by about 1°C.
I’m a little concerned by this. Even if I had no circulation in my hands, I don’t think they would get any colder than room temperature.
