If you cool it down to below That is why air conditioning systems often have a dehumidifier built-in. Without them, your walls in the home would be soaking wet during the summer. Unable to hold any more, it would rain. Colder climates often have lower humidity levels than warmer climates as colder air holds less moisture than warm air.

In winter, humidity levels tend to be typically lower. Whereas in summer, humidity levels will be higher, as air can hold more water vapor at a higher temperature. Small everyday tasks can affect humidity levels. Cooking, cleaning, dishwashing, breathing, clothes washing, showering, and other indoor processes release moisture into the indoor air, making indoor humidity levels rise.

Maintaining healthy humidity levels inside your house is vital. As explained below, poor humidity levels can have an impact on your health and the house itself. Too much humidity can cause dampness and mold, too little means the air becomes dry and uncomfortable. The humid conditions provide an excellent home for bacteria, as well as mold growth. The excess moisture in buildings can be caused by leaks, rain seeping in through windows and basements, or even rising damp from the ground floors.

More problems can develop as the levels rise. Did you know that dust mites could not survive without humidity from the air? The microscopic creatures can worsen allergies and asthma, so maintaining healthy humidity levels is key to minimizing them and their effects.

Dew point is simply a measure of how much moisture is in the air at a given time. Take the example where the dew point is 65 degrees and the air temp is 65 degrees. Hold that dew point at 65 with the air temp rising to In this scenario, it would feel quite humid or muggy and even uncomfortable despite the relative humidity being fairly low.

In fact, the heat index temperature — what it actually feels like outside — would be 98 degrees! We can see from these examples that the closer the temp is to the dew point, the higher the relative humidity. The farther apart they are the lower the relative humidity.
