How Indoor Humidity And Temperature Affect Your Health

During the winter, everyone wants to save money on their energy bills. Homeowners everywhere use tips and tricks to seal the warm air inside their homes and keep the cold air out. Since the wintertime leads to drier air, people will find any way possible to add moisture back into their homes.

While you might feel better after adding humidity back into your home, you might be unaware of the effects too much moisture — or too little — can have on your health. Indoor air quality directly relates to the health and wellness of occupants, so having the correct humidity and temperature can help you avoid serious health issues.

Below, you can find out how indoor humidity and temperature affect your health.

Humidity and Temperature

When you hear the word “humidity,” you might be taken to summertime. Humidity can affect how your hair lays on your head — the more humid the air, the frizzier it will be. It can also make outdoor workouts more difficult because the dense, moist air makes it harder to breathe.

To put it simply, humidity is the amount of water present in the air, and it directly affects the way you “feel” the temperature. A summer day could be in the high 70s, but if the humidity levels are high, that air might feel like it’s in the high 80s, and your body feels warmer. Your body’s response is to cool down, causing you to sweat, but if there’s too much humidity in the air, the sweat won’t evaporate, causing you to feel even warmer.

As the temperatures drop in the wintertime, the humidity levels decrease. The air is colder, which means the water molecules in the air shrink down, and they can’t hold in all of the moisture. Sweat will evaporate right off your body. You likely experience dry skin or chapped lips because the air is trying to get more moisture. Therefore, you’re colder.

You can tell whether the air around you is too dry by things such as dry skin, itchy throat, and bloody noses. Too-humid air will cause you to feel too hot, have frizzy hair, or notice mold around your home. Good indoor air quality, whether at home or work, is essential in keeping you healthy.

How Your Health May Suffer

Worse symptoms than dry lips or frizzy hair can result from indoor humidity and temperature. Here are some ways it can affect your health:

More Susceptible To Illness

The more humid your home is, the more viruses and other germs can thrive. Germs can stay airborne for longer as well, so even though someone in your home may have been sick a week ago, you could still catch a cold. A house that is too cold can also make you ill because your body cannot fight off the germs.

Interrupted Sleep

Sleep is essential for the human body to function correctly. It seems as though everyone has a preferred sleeping temperature. Yet, if you are too hot or too cold during the night, your body will respond by waking up. Interrupted sleep cycles can affect the rest of your day and can make you feel sluggish.

Worsening Of Previous Medical Conditions

If you’re turning on the humidifier during the winter, the cold temperature mixed with excessive moisture can lead to higher allergen levels and mold growing in your home. Those who have allergies to mold or a respiratory illness, like asthma, will experience a worsening of symptoms. Air that’s too dry may cause excessive coughing as well.

Increasing Contaminants in Your Home

When you clean your home with chemicals, especially during the winter, where do you think the particles go? They likely stay in your home, which can cause health concerns. Plus, building materials like carpet or wood can release contaminants into the air when it’s too humid, causing irritation and respiratory problems.

How To Control Indoor Air Quality

Fortunately, there are ways in which you can both control the temperature and humidity in your home. Ideally, the humidity in your home should be between 30% and 50%, and temperatures should be between 64 degrees and 70 degrees.

Humidifiers, dehumidifiers, house plants, and air purification systems all help control the temperature and humidity in your home. As long as they are properly maintained, you can live a healthier life with cleaner air.

Stay Healthy With Quality Air

You spend so much time in your home or even in your office at work. You deserve to have the best air quality to maintain your health and breathe easier.
