Comfort at home varies depending on temperature and moisture levels. But what levels are pleasant? Although the temperature should be between 20 and 22°C - up to 24°C, the level of comfort differs from one person to another.
Researchers conducted only a few scientific studies on the impact of temperature level on the health of home occupants. However, temperatures below 20 or 22°C can lead to physical stress, such as increased blood pressure in the elderly and people who suffer from chronic health problems. Viruses such as influenza survive better if the air is dry and colder, so it should never drop below 20°C.
Besides the actual temperature of the air in the home, its effect on occupants can vary depending on the relative humidity level.
Moisture content
The relative humidity (RH) plays a major role in indoor air quality. Health Canada believes it should not fall under 30% in winter and not exceed 55% in summer. Too much humidity in a house can lead to mould and dust mites, and they can cause respiratory problems such as asthma. Below 30% relative humidity, the air is too dry and it can affect the health of its occupants by irritating mucous membranes of the nose and the throat, and cause breathing difficulties.
If the moisture level becomes too high in winter, the house might require more ventilation. To ventilate without cooling the premises, consider a heat or energy recovery ventilator. If the humidity level is too low, the occupants can use a portable humidifier or one connected to a central heating system.
There are many ways to control temperature and humidity in a home, including daily use of the range hood and a bathroom fan.
