At first, I thought the thermostat was lying.
The little screen glowed a smug 22°C, the radiators ticked and hummed, and yet my hands felt like they belonged to someone waiting for a delayed train in January. I put on thicker socks, then a sweater, then another one. Still cold. The kind of cold that seeps into your shoulders and never really leaves.
I nudged the heat up a degree. Then another. I heard the boiler kick in again, worked out the extra euros in my head, and tried not to think about the gas bill. The room was “warm on paper”, but my body insisted otherwise.
Something wasn’t adding up.
“My home says 22°C, my body says 16°C”: what’s really going on?
The scene is almost cliché: you come home, drop your bag, tap the thermostat, and wait for comfort to arrive like a delivery. The temperature climbs, the numbers look reassuring, but that cosy wave never really hits. You walk from room to room, feeling little pockets of chill, like invisible drafty islands in your own house.
People often blame their “terrible circulation” or a mysterious vitamin deficiency. Yet energy experts hear this same complaint all winter long. The culprit is usually not your blood, but your building. Your body reads comfort in a completely different way than your thermostat does. And that silent disagreement costs you money, sleep, and a lot of frustration.
Take Marie, who lives in a 1970s apartment on the edge of Lyon. Last winter, she kept turning the heat up to 23°C, sometimes even 24°C, and still ended up wrapped in a blanket in front of the TV. She thought the radiators were failing. A technician came, checked everything, and shrugged: “They’re fine.”
A few weeks later, an energy auditor visited her building. He didn’t even start with the boiler. He went straight to the windows, the walls, the tiny gaps around sockets and skirting boards. With a thermal camera, her living room suddenly turned into a map of blue and purple wounds. “You’re heating the street,” he told her. Marie felt silly, but also relieved. The problem wasn’t in her head.
The science is brutally simple. Your body doesn’t just feel air temperature. It feels the average temperature of everything around you: the walls, the floor, the windows, the furniture. When your walls are cold, your body radiates heat toward them like a tiny stove, and you feel chilled, even if the air itself is at 21°C.
So you turn the heat up, trying to force your way to comfort. The boiler works harder, your bill climbs, yet the cold surfaces keep “stealing” your warmth. This is why two homes at the same thermostat setting can feel completely different. And why experts say that chasing comfort only through the thermostat is a bit like drying your hair with the car heater. It sort of works. But at what cost?
Stop punishing your thermostat: expert gestures that actually warm you
The first expert tip is almost disappointingly simple: track where your body feels cold, not just where the thermostat is. Stand barefoot in each room for a moment. Sit by the window. Put your hand on the wall near a corner. That’s your real “climate map”.

Energy advisors often start with micro-gestures that don’t require any renovation at all. Move your sofa away from an external wall by 10–15 cm. Add a thick rug on that freezing laminate floor. Seal the obvious gaps around windows with inexpensive foam tape. None of this is glamorous, but it slightly warms the surfaces that were draining your body heat. One degree of extra comfort, gained without touching the thermostat.
One of the biggest everyday mistakes, specialists say, is blasting the heat for a short time, then turning it down too far. The walls never really warm up, so the air swings wildly while the surfaces stay cold. You end up living in a yo-yo climate: too hot right after the boiler runs, too cold an hour later, never truly comfortable.
They also see people blocking radiators with massive furniture “for design reasons” or drying entire laundry loads on them for days. That’s like asking a marathon runner to breathe through a straw. The energy is there, but it can’t spread. Let’s be honest: nobody really optimizes every radiator and crack every single day. Yet the small things you do once, like unblocking a heat source or adding a curtain, quietly work for you every evening.
*The experts repeat the same sentence over and over: “Heat the home, not the outside world.”*
“People think they have a heating problem,” explains building engineer Daniel Frey, “but in most homes, they really have a **heat-loss problem**. Once you slow the heat from escaping, you often can lower your thermostat and still feel warmer.”
To break the “thermostat spiral”, many specialists suggest a simple checklist before raising the temperature again:
- Check for drafts with the back of your hand along windows, doors, and plugs.
- Free every radiator: no big sofas or heavy curtains directly in front.
- Add one layer to the floor (rug, mat) in the room where you sit longest.
- Close internal doors in the evening to keep a smaller, warmer zone.
- Lower the heat at night only slightly, not by 5–6 degrees in one go.
These moves sound basic, almost boring. Yet they change how your body experiences the same number on the thermostat.
When your home and your body finally agree on “warm enough”
Once you start paying attention, you notice that your “cold problem” is rarely just one thing. It’s the old window that leaks like a sieve, the tiled hallway that chills your feet, the habit of heating the whole apartment while you only use two rooms at night. You may also notice how different people in the same home feel completely different: the teenager in a T-shirt, the grandparent wrapped in three blankets.
Experts insist that the goal isn’t to live in a perfectly sealed, sterile bubble. It’s to find that sweet spot where your walls, floors, and air all sit close enough in temperature that your body stops fighting the room. A home where you no longer stare suspiciously at the thermostat, wondering if it’s lying to you. A home you step into and your shoulders simply drop.

FAQ:
- Why do I feel cold at home when the thermostat says 22°C?Your body senses not only air temperature but also the temperature of walls, floors, and windows. If those surfaces are cold, you radiate heat toward them and feel chilly even in “normal” room conditions.
- Is it better to keep the heating on low all day or turn it on and off?Experts generally prefer a relatively stable temperature with small day–night variations. Constant big swings mean cold walls and higher energy use.
- Can better clothing really replace turning up the heat?Warmer clothes help, especially on hands, feet, and neck. Yet if your home leaks heat badly, you’ll still feel uncomfortable. Clothing and building tweaks work best together.
- Do smart thermostats solve this problem?They can help optimize timing and avoid overshooting, but they don’t fix cold walls, drafts, or blocked radiators. Think of them as a tool, not a magic wand.
- When should I call a professional?If you keep increasing the temperature and still feel cold, or if bills jump sharply, an energy audit or heating check can reveal hidden leaks, poor insulation, or system issues that simple gestures can’t solve.
