The Perfect Average

If you’re aiming for the sweet spot, set your thermostat to around 21°C (70°F) during the day—experts say this is just right. Keep in mind, personal circumstances can shift this ideal temperature. Families with young children might want to keep it a few degrees warmer (about 24°C or 75°F), especially during bath time.

What to Choose for Nighttime

What to Choose for Nighttime
You’ve probably heard that a cooler room helps you sleep better. But what counts as "too warm"? While personal preferences matter, the general advice is to keep the bedroom between 18-19°C (64-66°F) at night. It might feel chilly to some, but it really supports restful sleep. Experts recommend layering up with pajamas or a thicker blanket instead of turning up the heat.

Why Cooler Is Better

Why Cooler Is Better
Many worry about cooler air around kids, but warm, stuffy rooms can actually make it harder for little ones to regulate their body temperature—and increase their chances of catching a cold if the indoor and outdoor temperatures differ too much. For you, too, a hot room can drain your energy and tire you out faster. A good, fresh airing can work wonders if you notice these signs! Still, don’t swing too far the other way—if your home is consistently cooler than average, everyone in the family might catch a chill. This goes for nighttime temps as well as daytime.

How to Set It Just Right

How to Set It Just Right
It might cost a bit more upfront, but investing in heating systems with individual thermostats for each room is worth it in the long run. You can program these devices in advance, so you won’t have to adjust the temperature every morning and evening. Just make sure the temperature difference between rooms isn’t too big—2-3°C (4-5°F) is fine, but more than that can cause discomfort.

Keep an Eye on Humidity!

Keep an Eye on Humidity!
Humidity plays a big role in how warm or cool we feel. Finding the right balance is key—too dry air can lead to irritated eyes, dry skin, and scratchy airways, while too much moisture encourages mold and dust mites, increasing allergy risks. Aim for a humidity level between 40-60%, which can be a bit higher for kids.
