What is the ideal bedroom temperature and why does an overheated room backfire even before you fall asleep?<\/strong> The answer is more specific than expected \u2014 and has less to do with heating than you would guess.<\/p>\n

\"Ideal
The bedroom doesn't have to be the warmest room in the flat. On the contrary \u2014 an environment a few degrees cooler than in the living room makes it easier to fall asleep.<\/figcaption><\/figure>\n

According to sleep recommendations, the ideal bedroom temperature is between 16 to 19 \u00b0C<\/strong>, with the optimum around 18 \u00b0C. Yet during the heating season, most Czech households maintain a temperature of 21 to 23 \u00b0C in the bedroom \u2014 exactly the same as in the living room. It is precisely this difference that is often the reason why a person tosses and turns in bed without knowing why.<\/p>\n

Why the ideal bedroom temperature is lower than you expect<\/h2>\n

Body temperature is not constant throughout the day. Roughly an hour to two hours before the usual time of falling asleep, it begins to drop naturally, and this drop is one of the signals the body uses to transition into sleep. For the heat to be able to leave the body, the surrounding air needs to be cooler than the skin.<\/p>\n

In an overheated room, this drop does not happen so easily. The body tries to cool itself down through more intense sweating, sleep is lighter, and a person wakes up more frequently \u2014 often so briefly that they don't even remember it. A cooler bedroom simply doesn't get in the way of this process.<\/p>\n

The other side of the coin applies equally: below 15 \u00b0C, the body, by contrast, expends energy on keeping warm, and sleep becomes fragmented once more. The goal is therefore not to freeze, but to hit the right range.<\/p>\n

How many degrees in winter and how many in summer<\/h2>\n

The seasons do not change the recommended range, they change the way you get into it. In winter it is about setting the heating and ventilation, in summer about shading and airflow.<\/p>\n\n\n\n\n\n\n\n\n

Children's and babies' bedrooms<\/h3>\n

For small children, the upper limit of the range is recommended, that is 18 to 20 \u00b0C. But the principle is the same as for adults: address the temperature through layering, not by overheating. An overheated child wakes up just like an overheated adult, they just find it harder to communicate.<\/p>\n

\"Ventilating
Five minutes with the window fully open will refresh the air better than an hour on the latch, and without the masonry having time to cool down.<\/figcaption><\/figure>\n

Air humidity is inextricably linked to temperature<\/h2>\n

A thermometer alone does not tell the whole story. It feels different to breathe at 18 \u00b0C and 30 % humidity than at 18 \u00b0C and 60 % humidity. The recommended range for relative humidity in the bedroom is 40 to 60 %<\/strong>.<\/p>\n

During the heating season, humidity typically falls below 35 %, which manifests as dry mucous membranes and a dry throat in the morning. A bowl of water on the radiator, houseplants or a humidifier can help. In summer and in poorly ventilated rooms, the problem is the opposite \u2014 humidity above 65 % makes even 20 \u00b0C feel uncomfortably stuffy.<\/p>\n

How to fine-tune the temperature with bedding and mattress<\/h2>\n

Air temperature is only half the equation. The other half is the microclimate right beneath your duvet, where you hover around 30 \u00b0C regardless of what the thermometer on the wall says. This is precisely where you can intervene most cheaply and quickly.<\/p>\n

\"Bedding
Two lighter duvets instead of one heavy one offer much more flexibility during the transitional period than fiddling with the thermostat.<\/figcaption><\/figure>\n
