Your grandma was never cold, and she didn’t have good insulation in her home growing up. How did people live before modern HVAC systems and creature comforts? Here’s how, and how you can too:

You Put On Layers

Before there was central heat and air conditioning, there was this fashion thing called “dressing in layers.”

You’ve heard the term “bundle up” before, right? This is where it comes from. Start with long underwear. Yes, it still exists. Then, wear your normal pants and socks (make sure to tuck your long underwear into your socks to prevent drafts).

Wear a base layer shirt (wool works best), and then on top of that wear something reasonably-loose-fitting, but not baggy.

Tuck your base layer shirt into your pants and wear a belt. Now, if you need more warmth, wear a sweater over that.

Now for the hat. Yes, people wore hats in the olden days – even inside. To keep the chill off your neck, consider wearing a scarf. Invest in thick blankets for those times when you’re sitting around and reading or watching T.V.

You Don’t Go Barefoot

Lots of people make this mistake. They get home, kick off their shoes, and turn up the heat. Why? Because even if you’re wearing layers, your feet are going to get cold. Most socks aren’t insulated. And, even the ones that are only do so much without shoes on.

If your feet get cold, get slippers with rubber soles. It might seem old-fashioned, but it’s sensible and allows you to walk around the house without having to crank up the heat to keep your feet warm.

You Wear PJ’s At Night

Pajamas seem like an “old person” thing, but Sleepyheads actually makes them look cool. Think of pajamas as “business clothes for bed.” You wouldn’t walk into work naked. Why climb into bed that way?

Intuitively, maybe you think that it “just makes sense” to wear nothing or minimal clothing to bed. But, if you’re trying to save money on your heating bill, or you’re just constantly cold at night, wearing pajamas is a simple way for you to stay warm and save money.

You Heat Your Bed

Don’t like climbing into a cold bed? Here’s how to heat it up before you jump in: use an electric blanket.

Remember those? Your mom probably has one. And, if she doesn’t, grandma definitely does.

Just make sure you turn it off before you actually go to sleep because they can be dangerous to run all night long. If you don’t have an electric blanket, can’t borrow or buy one, you can do something similar with a heating pad or a large tube sock full of rice.

Set the heating pad to the highest setting and then have it shut off after 15 minutes or so after you’ve climbed into bed.

Put a sock full of rice into the microwave and nuke it on high for a few minutes until it’s nice and hot.

Put it at the foot of your bed. In 15 minutes, you’ll climb into a warm bed. And, if you have a thick comforter, you should stay that way all night long.

You Open The Shades

During the day, open the shades. Let the passive solar gain from the sun heat the house. It may not bring it all the way up to temperature, but it will get you part of the way there.

You Spend Time Cooking

If you cook in the afternoon, including using the stove, you’ll stay warm – especially if you’re baking (something that’s fun to do on the weekends). You’ll be running around so much and the heat from the oven will keep the whole kitchen warm without you having to touch the thermostat.

You Get The Blood Pumping During The Day

Don’t sit around all day. If you work a desk job, take some time to move around, whether it’s walking, doing a lap around the office, or doing some unweighted air squats. If you can bang out 100 squats throughout the day, you will keep your joints lubricated, your blood pumping, and you’ll be surprised by just how much energy these require.

Plus, you’ll stay warm.
