Sleep quality

Explanation of the problem

Heat can result in hot bedrooms. Whether this occurs and to what extent depends on various characteristics of the home and the bedroom, such as the level of insulation, the orientation of the bedroom and windows in relation to the sun, the presence of sunshades or climate control, ventilation options, and the floor on which the bedroom is located. The location in the city also plays a role: is the residence in a warm neighbourhood or not? Furthermore, individual behaviour is crucial: is sun shading applied, and is ventilation done at the right times of the day?

High temperatures in bedrooms can cause sleep problems. As a result, people may sleep less soundly, less deeply, wake up more often, and take longer to fall back asleep. This can lead to  health problems. Poor sleep also results in daytime concentration problems, affecting both indoor and outdoor work productivity.

If it remains warm at night, it is more challenging to maintain a comfortably cool environment indoors, which is necessary for a good night’s sleep.
