Many human being think seeing your breath has everything to execute with temperature, but the spectacle has actually just as lot to perform with the quantity of humidity in the atmosphere.

Because our bodies contain nearly 70% water, the wait in our lungs is almost completely saturated with water vapor (water in gas form) and also is the same temperature as our body (98.6oF). Cold wait cannot hold as lot moisture as warm air. So once one exhales a warm, saturated breath top top a cold job the cold air swiftly lowers the temperature of our breath, whereupon the combination briefly reaches dew point. At dew point, air have the right to no longer host water vapor; once air is cooled past dew suggest water vapor turns to liquid form, the physical procedure known together condensation. The is this liquid kind of her breath – minuscule droplets that water – that creates the fleeting, misty cloud us see as soon as breathing in cold weather.
