Humidity is the measurement of water vapour in the air. Water vapour is water that has turned from a liquid in to an invisible gas. The term absolute humidity is the total amount of water vapour that a specified volume of air.

Then we have relative humidity which is the ratio of moisture content that air can hold. This relative humidity will vary depending upon the temperature of the air. Warm air will hold more moisture than cold air.

Humidity affects how we react to a given temperature. If you have a room at the same temperature but with a higher humidity level, we will feel warmer. This is because the body cools itself by sweating. When the air around you contains more moisture levels, the dampness on the skin will not evaporate so easily, making you feel warmer.

It is important to know the levels of humidity, especially indoors because the humidity can effect your health, how comfortable you feel and the condition of most of your household effects.

The hygrometer is an instrument that can be used for measuring the moisture content in the environmental air. Humidity meters are a range of moisture meters that can monitor the air moisture content in a particular area or specific room in a building. As well as measuring the humidity these meters will also include temperature readings as well. This is because air humidity is closely linked to the relative temperature. How to use a hygrometer

If the indoor humidity in your home is too high, it is natural to think that the room temperature is hot and stuffy, even if the room temperature is at a temperature that is normally comfortable to you. The opposite can be said for too little humidity in the home.

Keeping humidity levels within an optimal range will help to control bacteria, viruses, fungi and allergies. Measuring and keeping records of humidity levels in your home will also inform you as to how well your humidifiers, dehumidifiers and air conditioning are functioning. It is worth noting as well that keeping a proper humidity control in the home will reduce your energy bills as well as helping any indoor equipment perform properly.

Humidity outdoors will also make a difference to how a particular temperature will feel to you. The human body finds it extremely difficult to cope with hot weather where the air humidity is high. It is not possible to control outdoor humidity but knowing relative humidity levels can alert you as to how warm or cold the outside air will feel. Knowing outdoor humidity will inform you whether rain, snow or reduced visibility will occur. If the air has relative humidity of 100% the air is saturated with moisture and will not be able to hold anymore moisture. So even if the air cools just a little, the moisture content will be released in the form of fog or mist.

The Effect Of Humidity In The Home

It is essential to know the humidity level in you home to maintain good air quality and comfort within it.

Too much humidity will invite unwanted guests in such as mold, bacteria and dust mites.

Too little humidity in the home will cause nosebleeds, skin irritation, breathing problems and a large problem with static electricity.

The trick is to try and maintain a healthy balance.

How To Measure Humidity

To measure humidity you need to use a hygrometer. They can be designed for both or either indoor and outdoor use. There are 2 types of hydrometer; analogue and digital.

The analog hygrometer employs a moisture sensitve material which is attached to a coilded spring. This spring will in turn operate a needle on an easy to read display dial. With just a glance you will be able to see any current information about humidity levels. There are many examples of the analog hygrometer and many come combined with thermometers and have different finishes so that they can fit in to your home in a decorative manner.

The digital hygrometer employs a sensor to monitor the electric current which is affected by the moisture content levels in air. The digital hygrometer is more advanced than the analog hygrometer and with one you can keep records of high and low humidity measurements and any trends that occur. They are more precise with their results and do not require manual calibration.

To Control Mold One Must Control Temperature And Humidity

Mold is a form of fungus that can damage your health, your home and your possessions. In order for mold to thrive it requires the right temperature and moisture levels. Mold spores are everywhere and to control them one must control temperature and humidity.

An exposure to indoor mold can make allergies, asthma and respiratory disorders a lot worse. Mold can also irritate the eyes, skin and lungs of very healthy people. As well as affecting health it can also ruin household furnishings.

Being able to measure humidity and control it is a great step forward in preventing mold growth in your home. Mold thrives in the same temperature range that we humans find comfortable. When condensation occurs it will provide ideal conditions for the mold. So you cannot control mold through temperature alone. You also need to control and monitor humidity.
