What should be my house’s humidity?

Being concerned about having adequate heating and cooling for the home is a common thing that most homeowners do. Have you ever wondered what exactly the humidity level in your property should be, especially when summer or winter is coming around the corner? If you are curious to know the right home humidity level, then you have come to the right page.
Maintaining the right level of humidity within the property ensures that you and your family live a more comfortable life. On top of that, it will help regulate the temperature and protect your space.

In most studies, researchers suggest that the right humidity level for a house in winter should be 30% to 40% in order to stay cozy. And 50% to 60% humidity level is ideal for a home during summer.

What do you mean by humidity?

Before figuring out the right humidity level for your property, you need to understand what exactly humidity is. In general, the amount of water in the atmosphere is called humidity. Technically, it is quite trickier than that definition. To know humidity in a better way, you should know the major difference between absolute and relative humidity.
Absolute humidity versus Relative humidity

Absolute Humidity: An estimate of the actual amount of moisture or water vapor in the atmosphere regardless of air temperature

Relative Humidity: An estimate of the amount of vapor in a water-air mixture as compared to the maximum amount possible.

What’s the suitable humidity level for the air in your property?

When it comes to comfort levels, the humidity should be appropriate. However, changes in climate and weather have a huge impact on the humidity level in your home. Beyond that, it will depend on where you live, the type of clothing you’re wearing, and, most importantly, the temperature outside.

Many scientific researchers suggest that the suitable humidity for indoor environments should be between 40%- 60%. But the level should be below 50% to prevent and discourage mold growth. Make sure this humidity level suits your comfort levels. Also, the home’s humidity levels should be even with the outside humidity level.

According to Health Canada guidelines, a relative humidity level of less than 50% in the summer and 30% during the winter represents a suitable location for maintaining good indoor humidity.
Remember, the higher the humidity level in the atmosphere, the stickier and hotter you feel. With the drastic increase in humidity, one may experience certain health problems, including allergies, and asthma, leading to difficulty breathing.

If the air is dry, your skin may turn dry, which means the level of humidity is quite low. Also, you may experience other issues, such as itchy eyes or irritated throat.

What’s the ideal indoor humidity level?

You can often see that the absolute humidity level changes due to changes in outdoor temperature and the transition of seasons. During summers, the air comprises more moisture, while less moisture stays in the environment during winter. If you want to maintain a comfortable indoor environment, look at the information below, which helps you know the optimum indoor humidity level by outdoor temperature.

Problems caused by suboptimal humidity levels
