Feeling thermally comfortable means you’re neither too hot nor too cold. However, there are no strict measures to determine the sensation of heat: it is very subjective and variable. The activities you do and the clothes you wear play an important, but not exclusive, role: your personal thermostat is a determining factor.
The temperature felt is a very individual sensation. Some people will experience a feeling of freshness with a thermostat set to 22 °C, while others will start to sweat just thinking about it.
- The living rooms (living room, dining room, kitchen and office). The temperature should be around 66 °F – 68 °F (19 °C – 20 °C). However, if you are cooking or watching TV, the temperature you experience will not be the same. This is also the case if your home is humid or facing south.
- Bedroom. The recommended temperature is 62 °F. This helps to ensure good sleep. If you’re a little cold, a good cover will solve the problem. If you are really cautious, you can go up to 65 °F or 18 °C. This temperature is the minimum required where a baby sleeps (between 65 °F and 68 °F).
- The bathroom. A temperature of 63 °F or 17 °C is sufficient for the bathroom. During use, it should rise to 71 °F or 22 °C if you take a bath or a shower.
Why turn down the heat a little?
- For the environment. Lowering the thermostat a little and wearing an extra layer of clothing if necessary contributes to the reduction of greenhouse gas emissions. We thus concretely support the effort against global warming and for the preservation of the environment. One degree less represents on average a reduction of 7% in greenhouse gas emissions.
- For your wallet. Less heating consumption means lower energy bill.
- For your health. The temperature at home (or in the office) has an effect on our health. Exposure to too high a temperature can cause dehydration, headaches, fatigue, dizziness and even heart problems in people who are more sensitive, especially if they have high blood pressure or are taking certain medications (sleeping pills, anticoagulants, sedatives, etc).
Don’t go too low!
By lowering the temperature too much, there is a risk of humidity formation, especially in rooms with cold surfaces. It is therefore important first not to drop below a certain threshold (around 58 °F) and then to ensure good ventilation (fifteen minutes, morning and evening). In addition, this ventilation, whatever the temperature displayed by the thermostat, makes it possible to clean the ambient air (microbes, polluting particles, etc.). A home that is too confined can be the cause of health problems: drowsiness, headaches, allergy, irritation of the eyes and respiratory tract.
