So in general, regarding perishable foods like meat, most dairy, unshelled eggs and shell eggs (in the US) , cooked casseroles, and so on: if the food (or its perishable components) have been at room temperature for more than two hours, you should discard that food.
This directly effects how comfortable it will feel outside. Many times, relative humidity can be misleading. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%.
The term ârelative humidityâ simply means the amount of water vapor the air contains compared to the maximum amount it could hold at any given temperature. Indoor humidity can be controlled in two ways: it can be lowered with a properly sized and functioning air conditioning system (in some situations assisted with the use of a dehumidifier); or humidity can be raised by using a humidifier. Air conditioning and heating equipment affect humidity Before going into more detail on dehumidifiers and humidifiers, we should first list the roles air conditioning and heating equipment play in humidity control. In addition to cooling indoor air, the conditioning of air has to do with removing humidity. If an air conditioning system has too much cooling capacity, it cools too quickly and cycles on and off in short intervals.
