The temperature you keep your house at in winter matters a lot more than you think! Sure, here in Texas, you’re not really at risk of your pipes bursting from the temperature being too low when you’re gone…

But today, we’re going to talk about the dangers of keeping your home too cold, when it comes to your health.

Now, please don’t feel attacked if you’re one of those people who tries to keep the thermostat down in winter to save on your heating bill. We completely understand, and are in support of less strain on your HVAC system!

When we talk about what indoor temperature is too cold for your home, we mean less than 64 degrees. This is coming straight from the World Health Organization. They recommend not setting your thermostat lower than this, and they recommend not going less than 70 degrees if there are very young or very old people in your home (or people with a compromised immune system).

You may be rolling your eyes right now, but don’t worry, we wouldn’t make a statement like that without proof!

There are two big reasons why a low indoor temperature is dangerous:

1. Mold and Mildew

First, if your house is cold, but it’s humid outside, then condensation forms on your windows and elsewhere on your house! This is a breeding ground for mold and mildew.

This is also is a good reason not to turn your heat off when you go on vacation in winter!

And as you probably know, mold causes respiratory problems, even chronic and dangerous ones.

2. Getting Sick

When you’re cold, you’re more likely to get sick.

A lot of people think that this is because, when you’re cold, your immune system doesn’t function as well. But really, the primary reason people are more likely to get sick when they’ve been out in the cold is because it causes the MUCUS in their upper respiratory tract to get thicker! If mucus can’t travel around quickly in your respiratory system, then it can’t clean up bacteria and viruses.

Of course, it’s your HVAC system, your home, and your body, and we can’t tell you what to do.

(Plus, if your family is anything like our families, then chances are you all are passive-aggressively changing your thermostat back and forth anyway!)

We just wanted to let you know that, even with the comparably mild winters here in Texas…When it comes to immunity, arthritis pain, respiratory health, even blood pressure…The doc recommends never going below 64 degrees!

And as long as we’re talking about preventing health problems, then why don’t we talk about the health of your HVAC system? By opting into our preventive maintenance plan, you won’t have to worry about whether your HVAC system is going to be able to run from one winter to the next.
