The first cold snap always arrives the same way. One morning, you step out of the shower and the tiles feel like ice cubes, the mirror fogs up faster than usual, and you catch yourself eyeing the thermostat like it’s a forbidden dessert. In the back of your mind, that old rule echoes: “19 °C, not a degree more.” You half-remember it from the news, from leaflets left in the mailbox, from the winter when everyone was urged to save every kilowatt-hour.
You hesitate for a second… then nudge it up a notch.
In living rooms all over the country, that guilty little click is happening again.
The surprising part? Specialists are starting to say that 19 °C might no longer be the magic number.
So, is 19 °C really outdated now?
For years, 19 °C was treated like a moral limit. The “good citizen” temperature. Heating above it felt almost indecent, especially when energy prices spiked and the word “sobriety” landed in every government campaign. People boasted about surviving at 18 °C in wool socks, as if comfort had become a sign of weakness.
Now, heating experts and doctors are quietly revising that script. They say the right temperature isn’t a single sacred number pinned on every wall, but a range that changes with age, health, and room use.
The thermostat, they argue, should fit humans, not the other way around.
Energy agencies across Europe once repeated the 19 °C mantra like a hymn. It was simple, punchy, easy to include in a TV report between a weather map and a story about fuel prices. People needed a target. Some households followed it religiously, dropping their living room from 21 °C to 19 °C overnight. Others nodded politely and secretly stayed at 22 °C.
*Let’s be honest: nobody really does this every single day.*
Recent studies have shown what every frozen teenager knew already: not everyone copes at 19 °C. Seniors, babies, and people with certain medical conditions feel the cold more. For them, that famous number is less a benchmark and more a source of low-grade discomfort.

Specialists now lean towards a more nuanced rule: aim for around **20–21 °C** in living spaces, a bit cooler in bedrooms, and a touch warmer for vulnerable people. That one extra degree might sound trivial on paper, yet it changes how your body behaves. At 19 °C, your muscles tense slightly to stay warm, your extremities cool down, and your sense of comfort drops, especially if you’re sitting still.
At 20 or 21 °C, the body relaxes. You move more naturally. You don’t hunch over your laptop in a hoodie and scarf. Energy experts admit that this small rise, combined with better insulation and smarter habits, can hit a better balance between bills and well-being.
The “right” temperature is becoming less dogma, more conversation.
What experts really recommend for each room
Heating engineers now talk about zones, not just a single household number. In the living room, where you sit for long stretches, they increasingly suggest **around 20–21 °C** as a realistic comfort range. In bedrooms, they still favor 17–18 °C for sleep quality and fresh air, but with a clear caveat: if you’re shivering under the duvet, bump it up a little.
Kitchens, where ovens and stoves add heat, can easily stay at 18–19 °C. Bathrooms are the exception most people secretly respected all along. There, experts are comfortable recommending 21–22 °C during use, particularly for children and older adults.
Nobody wants to step out of a hot shower into a 19 °C icebox.
One energy adviser tells the story of a retired couple who prided themselves on keeping the thermostat at 18.5 °C “for the planet.” They wore three layers inside, drank tea constantly, and complained of joint pain all winter. When a home visit was carried out, the specialist didn’t start by blaming their habits. He checked drafts, old windows, a poorly balanced radiator system.
Once the circulation was adjusted and a few leaks sealed, he suggested they try 20 °C in the living room and 21 °C in the bathroom at specific times. Their bill didn’t explode. In fact, with better regulation and shorter heating cycles at the right moments, consumption stayed under control.
The difference was that they finally felt at home, not in a nicely insulated fridge.
Behind this shift lies a simple logic: cold is not just discomfort, it can be a health risk. When you live long-term in a home that’s too chilly, your body works harder to stay warm. For those with heart or respiratory problems, that extra strain is real. Children, who run around barefoot and forget their slippers, lose heat faster.
This is why pediatricians and geriatricians have gradually pushed back against the one-size-fits-all 19 °C rule. They talk more about “thermal security” than “thermal sobriety”. On the other side, climatologists remind us that pushing every interior to 23–24 °C is unsustainable.
The new recommendation sits in the middle: a home that protects your health while still respecting the planet and your wallet.
How to reach the new comfort range without exploding your bill
The first step is almost boring: know your actual temperatures. Many thermostats are poorly calibrated, mounted in the wrong place, or surrounded by furniture. Put a small independent thermometer in the middle of the room, at about chest height, and check what “20 °C” really looks like at home.
Then, play with timed heating. Program your living room to reach around 20–21 °C when you’re actually there in the evening, not all day while you’re at work. Let it drop by 1 or 2 degrees at night or when you’re out. Small, predictable shifts use less energy than sudden temperature jumps from 16 °C to 21 °C at 7 p.m.
Comfort comes as much from timing as from the number on the display.
We’ve all been there, that moment when you push the thermostat up to 23 °C “just to take the chill off” and forget about it for hours. The mistake isn’t wanting warmth, it’s relying only on the boiler. Experts now encourage layering strategies: a decent pair of socks, a thicker curtain, a draft stopper under the door, a rug on tiles.
None of this replaces heating, but it reduces the need to overcompensate. Many households live in poorly insulated buildings and feel guilty for not sticking to the 19 °C slogan. Guilt doesn’t warm anyone. What helps is accepting that you’re allowed to adjust according to your body, while shaving off waste where you can.
Comfort is not a moral failure. It’s a parameter you can tune with a bit of nuance.
“People cling to 19 °C because they were told it was the patriotic number,” explains a heating consultant who advises both families and small businesses. “What I tell them now is simple: aim for 20–21 °C in main rooms, cooler where you sleep, and warmer where you’re naked. Then fight energy waste, not yourself.”
- Adjust day and night: keep living areas around 20–21 °C when occupied, drop by 1–2 °C at night.
- Different rooms, different rules: bathrooms slightly warmer, bedrooms slightly cooler, corridors lower still.
- Seal invisible leaks: windows, doors, electrical outlets on outside walls can leak more heat than you think.
- Bleed radiators once a year: air pockets reduce heat output and tempt you to turn the thermostat up.
- Watch the “bonus degree”: every extra degree above your comfort range pushes the bill up with no real benefit.
The end of the sacred number, the beginning of personal comfort
The era of a single national thermostat setting is quietly fading. The 19 °C rule helped raise awareness in a moment of crisis, but it forgot something essential: homes are different, bodies are different, and winters are not all alike. You might genuinely feel fine at 19 °C in a well-insulated apartment with sunlight pouring in every afternoon. Your neighbor, in a damp ground-floor flat, might be shivering at 20 °C.
The new expert message is less catchy but more human. Instead of repeating one number, they talk in ranges, routines, and priorities. Warm the right rooms, at the right times, to the right level for the people who live there. Accept that children, seniors, and sick relatives may need that extra degree.
The rest comes down to conversations around the thermostat: within couples, between generations, even among roommates. A small plastic box on the wall has become a mirror of how we negotiate comfort, money, and climate anxiety.
The next time your finger hovers over the +/- button, the real question might not be “Am I betraying 19 °C?” but “What temperature genuinely lets us live well here, today?”

FAQ:
- Is 19 °C officially no longer recommended?
Public guidelines still mention 19 °C as a benchmark, mainly for energy savings, but many experts now speak in terms of ranges, often around 20–21 °C for living spaces, adjusted to people’s needs.- Does one extra degree really change the bill that much?
On average, each extra degree can raise heating consumption by around 7%, especially in poorly insulated homes, so the idea is to stop at the lowest temperature where you still feel genuinely comfortable.- What temperature is healthiest for sleeping?
Most sleep specialists suggest 17–18 °C, with a good duvet and ventilation, but if you’re cold in bed or sick, nudging it slightly higher is acceptable.- How do I know if my home is too cold for my health?
Warning signs include constant shivering, very cold hands and feet indoors, condensation and mold on walls, and aggravated joint or respiratory issues during winter days at home.- Can I stay eco-friendly without sticking to 19 °C?
Yes, by targeting a reasonable range around 20 °C, improving insulation where possible, avoiding overheating empty rooms, and using programmable systems, you can stay both comfortable and energy-conscious.
