No one likes dry skin. Think about it: it makes one feel flaky and depending on severity, it may be painful. However, the cause of dry skin is not always due to inadequate care. At times, it is caused by home heating system. How exactly does this happen and what can one do to avoid dry skin caused by HVAC systems?
First of all, it is important to know how the skin works in order to appreciate why it gets dry at times. The skin is a very active component of the human body. The skin works as a radiator for the body, cooling it down to maintain the temperature of the body. In addition, it allows for the body to perspire thereby releasing waste substances from the body through sweat.
Through perspiration, the body cools down. The skin secrets water onto the surface of the skin which evaporates and in the process body cools down. It is the same mechanism that other mammals use to keep their bodies cool.

For evaporation to occur, water requires specific latent heat. Normally, the body provides this heat and in the process, cools down. In most cases, the skin is able to replenish the water that has evaporated from the skin. However, when the water evaporates faster than the skin can replenish it, dry skin is the result.
Heating systems work by elevating room temperature. If the thermostat settings are not too high, then there is no problem. However in some cases, the settings are set too high. In this environment, the body looses water faster than it can replenish leading to dry skin. This explains why it is important to set HVAC systems at comfortable levels. Dry skin can also be a sign of dehydration. It is important to drink water at all times whether on a hot day or on one where artificial heating is in use.
