If vomiting continues, seek immediate medical attention. At 75 degrees Fahrenheit & 65% RH there is no risk for mold. Dew point is the temperature of the air when it cools to a point where it saturates with water vapor (known as the dew point temperature). On the other hand, if the outdoor air is very cold, your furnace will warm the air, and its relative humidity will lower. Additionally, high relative humidity can damage the interior of your home and your HVAC system. The ideal indoor humidity level in summer is 40 to 50 percent; any higher than that and you run the risk of mold and mildew growth.
